• Download source code - 2.4 MB

Introduction

In this article, we will see in detail how to create a Dynamic MVC Dashboard with Chart and Data display using AngularJS and WEB API. Using this web application now, you can write your own SQL query to bind dynamic Dashboard with Chart and Data. This program makes your work easy to display any Table/Columns details with your entered where Condition, Order BY and with Group By Option for the selected database on your home page with both data and chart.

In our previous article, we explained in detail how to display any data on home page dashboard on our MVC web application. In this article, we will see in detail about how to display data and Chart on dashboard in MVC Web application using AngularJs and Web API.

In this demo application, we have drawn Pie Chart in our MVC Dashboard page. You can draw any chart as per your requirement. In our previous article, we explained how to draw Chart like, Line, Pie, Bar, Donut, Bubble and Line & Bar Chart in MVC application. We used the same logic to draw chart on our MVC dashboard page.

Features in Shanu MVC Dashboard

1. Dynamic SQL Query
2. Column Names
3. Table Names
4. Where Condition
5. Group By
6. Order By
7. Chart SQL Query
8. Chart Setting and Draw Chart

Here, we will see details of each part.

Kindly refer to our previous article for sections from 1 to 6. We explained in detail about each section with animated images.

This article has all the same features with additional Chart Feature to be displayed on our MVC Dashboard.

7. Chart SQL Query

To display chart, first we need to write our select query to display both Chart Item and Value.

Here is the sample query to display Chart on our MVC dashboard page. Here, for chart binding, user can enter the complete select query to bind the result in the combobox.

Sample Select query to be used for our application:

Select ItemName as Name, SUM(Price) as Value FROM ItemDetail _
       GROUP BY ItemName ORDER BY Value, Name

For draw chart, we fixed the standard as always display 2 columns, one is Name and another one is Value. Here, name is the any name (Legend) to be displayed for chart and value is the actual value to draw the chart. In search button click, we first bind the chart item result to the combobox. We will be using this combobox result draw chart.

8. Chart Setting and Draw Chart

User can add Chart Title, Watermark Text as per your requirement at runtime and click on “Click to Draw Chart" button to draw your chart on Dashboard.

Note: You can display any chart data from any table from the given database. All you need to do is write the select query for chart with Name and Value column.

Prerequisites

Visual Studio 2015: You can download it from here.

Using the Code

Step 1: Create a Sample Database and Table for Testing This Application

Here is a SQL script to create database and Table with insert query. Kindly run the below code in your SQL Server to create DB and Tables.

Step 2: Create your MVC Web Application in Visual Studio 2015

After installing our Visual Studio 2015, click Start, then Programs and select Visual Studio 2015 - Click Visual Studio 2015. Click New, then Project, select Web and then select ASP.NET Web Application. Enter your project name and click OK.

Select MVC, WEB API and click OK.

Now, we have created our MVC Application as a next step, we add our connection string in our Web.Config file. Here, we are not using Entity Framework. Here, we will directly get the data from our MVC Web API controller method using normal ADO.NET method.

<add name="dashboard" connectionString="Data Source=SQLSERVERNAME;
Initial Catalog=DashboardDB;Persist Security Info=True;User ID=UID;Password=PWD" 
providerName="System.Data.SqlClient" />

Kindly update with your SQL server connection.

Step 3: Add web API Controller

Right click Controllers folder and click Add and click on Controller.

Here, we will add a WEB API Controller to be used for our AngularJS.

Select Web API 2 Controller – Empty and click Add. Next, enter the controller name as DashboardAPIController.

Get Method

Here, use the Http Get method to get all our dynamic data from database using normal ADO.NET method.

[HttpGet]
        public string getDashboardDetails(string sqlQuery, string columnName, 
        string tableNames, Nullable<int> isCondition, string conditionList, 
        Nullable<int> isGroupBY, string groupBYList, 
        Nullable<int> isOrderBY, string orderBYList)
        {
            if (sqlQuery == null)
                sqlQuery = "";

            if (columnName == null)
                columnName = "";

            if (tableNames == null)
                tableNames = "";

            if (isCondition == null)
                isCondition = 0;

            if (conditionList == null)
                conditionList = "";

            if (isGroupBY == null)
                isGroupBY = 0;

            if (groupBYList == null)
                groupBYList = "";

            if (isOrderBY == null)
                isOrderBY = 0;

            if (orderBYList == null)
                orderBYList = "";

            string connectionString = 
                   ConfigurationManager.ConnectionStrings["dashboard"].ToString();
            DataSet ds = new DataSet();
            using (SqlConnection connection = new SqlConnection(connectionString))
            {
                // Create the SQL command and add Sp name
                SqlCommand command = new SqlCommand();
                command.Connection = connection;
                command.CommandText = "USP_Dashboard_Select";
                command.CommandType = CommandType.StoredProcedure;

                // Add parameter for Query.
                SqlParameter parameter = new SqlParameter();
                parameter.ParameterName = "@sqlQuery";
                parameter.SqlDbType = SqlDbType.NVarChar;
                parameter.Direction = ParameterDirection.Input;
                parameter.Value = sqlQuery;

                command.Parameters.Add(parameter);

                // Add parameter for Column Names
                SqlParameter parameter1 = new SqlParameter();
                parameter1.ParameterName = "@columnName";
                parameter1.SqlDbType = SqlDbType.NVarChar;
                parameter1.Direction = ParameterDirection.Input;
                parameter1.Value = columnName;
                 
                command.Parameters.Add(parameter1);

                // Add parameter for Table names
                SqlParameter parameter2 = new SqlParameter();

                parameter2.Value = tableNames;
                 
                command.Parameters.Add(parameter2);

                // Add parameter to check for  Where condition
                SqlParameter parameter3 = new SqlParameter();

                parameter3.Direction = ParameterDirection.Input;
                parameter3.Value = isCondition;
                 
                command.Parameters.Add(parameter3);

                // Add parameter for Where conditions
                SqlParameter parameter4 = new SqlParameter();
                parameter4.ParameterName = "@ConditionList";
                parameter4.SqlDbType = SqlDbType.NVarChar;
                parameter4.Direction = ParameterDirection.Input;
                parameter4.Value = conditionList;
                 
                command.Parameters.Add(parameter4);

                // Add parameter to check for  Group By 
                SqlParameter parameter5 = new SqlParameter();
                parameter5.ParameterName = "@isGroupBY";
                parameter5.SqlDbType = SqlDbType.NVarChar;
                parameter5.Direction = ParameterDirection.Input;
                parameter5.Value = isGroupBY;
 
                command.Parameters.Add(parameter5);
               
                // Add parameter for Group By
                SqlParameter parameter6 = new SqlParameter();
                parameter6.ParameterName = "@groupBYList";
                parameter6.SqlDbType = SqlDbType.NVarChar;
                parameter6.Direction = ParameterDirection.Input;
                parameter6.Value = groupBYList;
                 
                command.Parameters.Add(parameter6);

                // Add parameter to check for Order By
                SqlParameter parameter7 = new SqlParameter();
                parameter7.ParameterName = "@isOrderBY";
                parameter7.SqlDbType = SqlDbType.NVarChar;

                command.Parameters.Add(parameter7);

                // Add parameter  for OrderBY
                SqlParameter parameter8 = new SqlParameter();

                parameter8.SqlDbType = SqlDbType.NVarChar;
                parameter8.Direction = ParameterDirection.Input;
                parameter8.Value = orderBYList;
                 
                command.Parameters.Add(parameter8);
                
                connection.Open();

                using (SqlDataAdapter da = new SqlDataAdapter(command))
                {                  
                    da.Fill(ds);
                    connection.Close();
                }
            }
            return DataTableToJSONWithJavaScriptSerializer(ds.Tables[0]);
        }

Step 4: Creating AngularJs Controller

First, create a folder inside the Script folder and we give the folder name as “MyAngular”.

Now add your Angular Controller inside the folder.

Right click the MyAngular folder and click Add and New Item > Select Web > Select AngularJs Controller and give name to Controller. We have given my AngularJs Controller as “Controller.js”.

If the Angular JS package is missing, then add the package to your project.

Right click your MVC project and Click -> Manage NuGet Packages. Search for AngularJs and click Install.

Modules.js: Here, we will add the reference to the AngularJS JavaScript and create an Angular Module named “AngularJs_Module”.

// <reference path="../angular.js" />  
/// <reference path="../angular.min.js" />   
/// <reference path="../angular-animate.js" />   
/// <reference path="../angular-animate.min.js" />   
var app;
(function () {
    app = angular.module("dashbordModule", ['ngAnimate']);
})();

Controllers: In AngularJS Controller, we have done all the business logic and returned the data from Web API to our MVC HTML page.

1. Variable Declarations

Firstly, we declared all the local variables that need to be used.

app.controller("AngularJs_Controller", 
    function ($scope, $filter, $timeout, $rootScope, $window, $http) {
    $scope.date = new Date();
    $scope.MyName = "shanu";

    $scope.isQuerys = false;
    $scope.Querys = "";
    $scope.ColumnNames = "UserName,UserType,Phone";
    $scope.TableNames = "UserDetails";

    $scope.isCondition = false;
    $scope.whereCondition = 0;
    $scope.Conditions = "";

    $scope.isGroupBy = false;
    $scope.GroupBy = 0;
    $scope.GroupBys = "";

    $scope.isOrderBy = false;
    $scope.OrderBy = 0;
    $scope.OrderBys = "";
    // Array value to check for SQL Injection
    $scope.sqlInjectionArray = ['create', 'drop', 'delete', 
                                'insert', 'update', 'truncate',
                                'grant', 'print', 'sp_executesql', 
                                'objects', 'declare',
                                'table', 'into', 'sqlcancel', 
                                'sqlsetprop', 'sqlexec',
                                'sqlcommit', 'revoke', 
                                'rollback', 'sqlrollback', 'values',
                                'sqldisconnect', 'sqlconnect', 
                                'system_user', 'schema_name',
                                'schemata', 'information_schema', 
                                'dbo', 'guest', 'db_owner',

Search Method

We call this method on search button click. Here, we check for all the validation of user entered data before passing all the parameter to our Web API method. In this method, we have commented for each condition checking.

In this method, we call the ‘searchbildChartData” method to bind the select result to the combobox.

//search Details

                alert("Enter Your Chart Select Query !");
                return;
            }
    }

Main Search Method

Finally, after validation, we call our main bind method to pass all the parameter to our WEB API to get the dynamic data from the database.

    //Main Select and Bind function
    //All query details entered by user after validation, 
    //this method will be called to bind the result to the Dashboard page.
    function searchTableDetails(sqlQuery, columnName, tableNames, 
    isCondition, conditionList, isGroupBY, groupBYList, isOrderBY, orderBYList) {
       
        $http.get('/api/DashboardAPI/getDashboardDetails/', { params: 
        { sqlQuery: sqlQuery, columnName: columnName, tableNames: tableNames, 
        isCondition: isCondition, conditionList: conditionList, isGroupBY: isGroupBY, 
        groupBYList: groupBYList, isOrderBY: isOrderBY, 
                     orderBYList: orderBYList } }).success(function (data) {

            $scope.dashBoadData = angular.fromJson(data);;
            //alert($scope.dashBoadData.length);

            //if ($scope.dashBoadData.length > 0) {

            //}
        })
   .error(function () {
       $scope.error = "An Error has occurred while loading posts!";
   });
    }

Chart Data Bind Method

This method will be called from our main method to bind the result to combobox to draw our Pie chart.

// For binding the Chart result to Listbox before bind result to Chart
    function searchbildChartData(sqlQuery, columnName, tableNames, 
    isCondition, conditionList, isGroupBY, groupBYList, isOrderBY, orderBYList) {
 
        $http.get('/api/DashboardAPI/getDashboardDetails/', { params: 
        { sqlQuery: sqlQuery, columnName: columnName, tableNames: tableNames, 
        isCondition: isCondition, conditionList: conditionList, isGroupBY: isGroupBY, 
        groupBYList: groupBYList, isOrderBY: isOrderBY, 
        orderBYList: orderBYList } }).success(function (data) {

            $scope.itemData = angular.fromJson(data);           
            $scope.itemCount = $scope.itemData.length;          
            $scope.selectedItem = $scope.itemData[0].Name;           
            $scope.minsnew = $scope.itemData[0].Value;            
            $scope.maxnew = $scope.itemData[$scope.itemData.length-1].Value;    
        })
   .error(function () {
       $scope.error = "An Error has occurred while loading posts!";
   });
    }

Step 5: Draw Pie Chart for our Dashboard

We are using the Jquery to draw our Pie Chart. In Draw Chart button Click event, we call the drawPieChart jQuery method to draw our chart. In this method, we get chart value and name from the combobox and draw the chart on the Canvas tag which we placed on our MVC Dashboard main page.

function drawPieChart() {
     
        var lastend = 0;
        var XvalPosition = xSpace;

        chartWidth = (canvas.width / 2) - xSpace;
        chartHeight = (canvas.height / 2) - (xSpace / 2);

        widthcalculation = parseInt(((parseInt(chartWidth) - 100) / noOfPlots));

        //Draw Xaxis Line
        //-- draw bar X-Axis and Y-Axis Line
        var XLineStartPosition = xSpace;
        var yLineStartPosition = xSpace;
        var yLineHeight = chartHeight;
        var xLineWidth = chartWidth;

        colorval = 0;
        var chartTotalResult = getChartTotal();

        $('#DropDownList1 option').each(function () {
            
            if (isNaN(parseInt($(this).val()))) {
                
            }
            else
                {
        
            ctx.fillStyle = pirChartColor[colorval];
            ctx.beginPath();
            ctx.moveTo(chartWidth, chartHeight);
            //Here we draw the each Pic Chart arc with values and size.
            ctx.arc(chartWidth, chartHeight + 6, chartHeight, lastend, lastend +
              (Math.PI * 2 * (parseInt($(this).val()) / chartTotalResult)), false);
          
            ctx.lineTo(chartWidth, chartHeight);

           ctx.fill();
            lastend += Math.PI * 2 * (parseInt($(this).val()) / chartTotalResult);

            //END Draw Bar Graph  **************==================********************
           
            }
            colorval = colorval + 1;
        });
    }

Points of Interest

First, run the SQL Script to create database and tables and then run the script to create Stored Procedure. Update the Web.Config Connection string with your local SQL Server Connection. Run the application and test with provided sample select scripts to display the dynamic data with chart.
