You need to write code to handle the on sort event. In that event you should use a dataview and sort it then bind the data to the grid. Check MSDN for on sort events in gridviews.

Please help on this I do not really understand how to do.

I understand that I have to write

Public Event Sorted As EventHandler

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim instance As GridView
Dim handler As EventHandler
AddHandler instance.Sorted, AddressOf func1
end sub

1) what is func1 in my case?
2) How do I link this to the hedearcell of the new header row that I add to the sorting event?

PLease help

In my application, initially i disabled backbutton function. Now i want to enable it. This command "private void DataGrid1_ItemCommand(object source, System.Web.UI.WebControls.DataGridCommandEventArgs e)" is not firing second time when i am clicking the linkbutton in datagrid. In datagrid, some records will be displaying, we will open the records by the name. The record details will be opened in diffrent page. Then, if i want to open another record, i have to go back by clicking BackButton. If i click another record, the previous record only opens.

Prabhakaran.

Convert the column with that button to a template column. Double click the link button in design view to get a method for the button in your code behind.

In the code behind LinkButton lb = (LinkButton) sender;

you can use that to get to your command argument. lb.namingcontaine or parent contrails the gridrow so you have access to that as well. I never use the item command.

Passing parameters to SP

Hi,

I have an SP which provides all the data for a datagrid to be populated(Just like a view). With a view, I would just say something like:

Select * From vw_View
And then fill a dataset..

What is the deal when I need to use a Stored Procedure instead of a view? How do I retrieve the info?

Thanks.

Hi,
If you want a result from stored procedure just run the select query in the store procedure and use the data adapter to fill a dataset. As easy as it sounds.
Hope i am clear enough.

Thanks for the reply!

Here what I have when I use a view:

<br />
Dim ds As DataSet = New DataSet<br />
            Dim Conn As SqlConnection = New SqlConnection(WebConfig.ConnectionString)<br />
            Dim sTable() As String = {"tblRequest"}<br />
            Dim sSql As String<br />
<br />
            sSql = "SELECT * FROM vw_Quote2 "<br />
<br />
            If iProjectID > 0 And iStageID > 0 Then<br />
                sSql = sSql & " WHERE inProjectID = " & iProjectID & " AND inStageID = " & iStageID<br />
            ElseIf iProjectID > 0 And iStageID = 0 Then<br />
                sSql = sSql & " WHERE inProjectID = " & iProjectID<br />
            End If<br />
<br />
            sSql = sSql & " Order By vchStageNumber"<br />
<br />
            SqlHelper.FillDataset(Conn, CommandType.Text, sSql, ds, sTable)<br />
<br />
            Return ds

Now that I am useing the SP, I have All my SELECT statements in there BUT, I do not have the conditions for those 2 Dropdowns. I dont know how to encorporate them. Also, I do not know how to use the SP in this case.

Sorry if I sound a bit dumb, but things arent clicking with me lately. I am finding it very hard to understand get my head around SPs Frown | :(

Thanks again!

But be wary mate, there will always be people who are unaware of this Poke tongue | ;-P

Thanks again. I will see how I can change it. D'Oh! | :doh:

The number of people that were unaware seemed to be going down for a while and in the last few days there has been a spate of people that have really compromisable code.

I'll just have to keep up the fight to ensure that as many people understand what a SQL Injection Attack is and how to write better code.

Hi,

First of all, write a store procedure that will contain all the queries in your view. If you want to check some condition
you can do it in a stored procedure too. (iProjectID and iStageID). You will have to learn the sql syntax of IF statements.
The values which i told you in last sentence, will be passed as input parameters to the stored procedure. This can be done
as told by other poster, using the command object and setting its CommandType property to StoredProcedure. Then add the
parameters to be passed to the stored procedure.

One of the things you might be wondering about, how to return multiple rows from a stored procedure. If you just
execute the query from SP and fill dataset using data-adapter, then you will get data tables for all your queries in the dataset.

Thank you mate! I didn't realise SPs can be so flexible. I will surely have a crack at that.

Also, to the fight against injection attacks.. Keep up the good work! Big Grin | :-D

create your command the same way, then set it's CommandType as System.Data.CommandType.StoredProcedure.

Add the parameters to the command's Parameters using .Add();

then do an ExecuteReader().

Hi I'm developing an application wherein I'm calling some classes in webforms which do some searching,addition etc on the database. Now what I need to know is how can I code the classes in such a way that if I need to call these classes through web service I won't have to redo the code.

Thanks

Encapsulate the functionality in a class, then use that class in any project. You can add the class to the GAC or simply use xcopy.

Hi, Firstly thanks for replying. I'm already aware of these things what I'm asking is can a single class serve both webservice & web form. As in a web service syntax is little different like [WebMethod] attribute etc.
