can you please give an example?

BuBa1947 9-Dec-14 16:17pm View

The exception is because the web method GetMyEmployeeId() returns an array containing the user ID's but i am trying to return the method's array of user ID's as integer. Pls suggest instead of integer what should I declare the property employeeID?

BuBa1947 9-Dec-14 14:50pm View

pls see my improved question, have added the function

BuBa1947 2-Dec-14 13:59pm View

How to pass the ID's to the webmethod?

BuBa1947 7-Mar-13 10:08am View

yes, my problem is the selecteditem-row stays idle only for those 5 secs, after 5 secs, my datagrid loads the selecteditem of the first row automatically. could you pls suggest tell me how..

BuBa1947 4-Mar-13 18:12pm View

No, i haven't..

BuBa1947 4-Mar-13 18:03pm View

I am sorry for the confusing the question, it is how to move from one tab to another tab item wen a user selects a row on the datagrid.

BuBa1947 26-Feb-13 10:37am View

I have already tried using breakpoint at top of the method. everything works fine until I select the item in the second datagrid, there it takes a pause for 3-4 secs and an exception occurs at da.Fill(row) :(

I suspect here,

do I have to create a separate property again for <PersonDetails> as

private ObservableCollection<PersonDetails> personDetails;
public ObservableCollection<PersonDetails> Details
{
get { return personDetails; }
set { this.SetProperty<observablecollection<persondetails>>(ref this.personDetails, value); }
}

but this creates duplicate for Details.

did u have a look at my MainViewModel. is everything ok there Mr.Jason. what do u think?

BuBa1947 26-Feb-13 9:28am View

Hello Mr.Jason,
i am trying to work on this selecteditem on three datagrid's now. but i am stuck with a silly error. if u have time pls have a look over this post - http://www.codeproject.com/Questions/553025/Selectedplusitemplusforplusmutilpleplusdatagrid-27

Thank you

Hello Mr.Jason,

actually this explanation is quite confusing. is it possible to explain with some example.

BuBa1947 20-Feb-13 9:18am View

Hello Mr.Jason,

First of all, let me thank u.. I tried this above Model and finally I got the output which i needed. I will post the solution down. This time I have used my Person database which has two tables, Persons and Persondetails, where it should display the data in the Persondetails datagrid when a row is selected on the Persons Datagrid.

I have created class for Person and PersonDetail, One ViewModel as MainViewModel and a View which is present already. but I dont know where to place the Timer here ( as you have mentioned above "don't place the timer in the Model, but rather in ViewModel"). But I am afraid to touch my code which is running perfectly now.

the need for timer is to update my grid every 3 seconds because I have many incoming new data in my database. kindly have a look at my updated solution & output. ( this works fine without the Timer). Kindly have a look at Solution 3.

BuBa1947 19-Feb-13 9:57am View

Jason, kindly have a look at my edited question. I have added new code blocks. is this approach ok ?

BuBa1947 19-Feb-13 9:19am View

I am gonna try and get back to you Jason. Thanks a lot for taking effort to explain.. I actually saw this reply very late, as i got many e-mails and thought it was a spam.

BuBa1947 7-Feb-13 4:49am View

Many Thanks for your reply Jason.
but I have a query, each of the datagrid ( for eg. here is HOST and LOG file) has to select the items from their respective tables from the database. how can I implement it when I have one ViewModel ?

BuBa1947 9-Jan-13 17:17pm View

Hello Mr.Sanjeev Singh,
I am facing the similar issue, I have to auto refresh a WPF page for every 60 seconds ( after updating a record). Please help me with issue.

BuBa1947 9-Jan-13 8:52am View

@Sandeep Mewara: Kindly check my code above. is that the right way ?

BuBa1947 9-Jan-13 7:37am View

Thank you sanjay, I have refereed these links already. But in both links, they have binded the Itemsource from list , not from a database. my question is , how to bind Pie Chart datacontext to a DataBase

BuBa1947 13-Dec-12 5:24am View

is it this way ?

dataGrid1.ItemsSource = ds.Tables[0].DefaultView;

BuBa1947 13-Dec-12 5:24am View

is it this way ?

Yes,I have already tried something..
I created a converter that gets the cell value, for instance Value='Stopped'
and it highlights as red.

public class myConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
string cellvalue = value.ToString();
return cellvalue = ("Stopped");
}
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{
return false;
}
}

I have already setup'd a monitoring agent that looks over my server statuses.
My database is already defined and is running well. Now I have to bring this to a presentation layer, to display the server status.
So I decided to display in a form of traffic signal (RED-stopped, Green-running and Yellow for critical). But I don't have much knowledge in WPF animation.

BuBa1947 12-Dec-12 11:32am View

BuBa1947 11-Dec-12 4:57am View

Do I have to add the Converter class as a part of the MainWindow.xaml.cs class or add a new class naming Converter and then mapping it to the MainWindow.xaml.cs class ?

Because on the first try, I added the as a part of Mainwindow.xaml.cs on the first try, then my Intellisense didn't detect, but when I added a separate class as Converter.cs , my Intellisense detects but I dont know the way to map to my Mainwindow.xaml.cs class :(

Converter.cs

public class Converter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
string cellvalue = value.ToString();
return cellvalue = ("Pass");
}
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{
return false;
}

MainWindow.xaml.cs

namespace BlinkApplication
{
public partial class MainWindow : Window
{
SqlConnection cn;
SqlDataAdapter da;
DataSet ds;
public MainWindow()
{
InitializeComponent();
DataContext = this;
cn = new SqlConnection(@"Data Source=CZC0239ZWZ\SQLEXPRESS; Initial Catalog =Student; Integrated Security=true");
cn.Open();
}

private void Window_Loaded(object sender, RoutedEventArgs e)
{
da = new SqlDataAdapter("select * from dbo.View_StudentResults",cn);
ds = new DataSet();
da.Fill(ds);
dataGrid1.ItemsSource=ds.Tables[0].DefaultView;

}

}
}
