Hi. I have a Datagrid with 2 check box columns, one is Match From and the other is Match to. When a user selects a any row from match From column the rest of the check boxes within that row will be disabled including the one next to it. The user will be able to click in the Match To column for multiple checks. I also have a Match button. After selecting what is needed within the relevant check boxes the user must click the Match button. When the user clicks the Match button, the info from the Match From column(only the clicked items) button must change to the info that is in the Match To row. Currently I have a Javascript the can do the enabiling and disabiling. What I need to know is how am I going to write the code behind for when you click the Match Button.

You need to add an attribute for the OnClick event handler:

OnClick="Button1_Click"

Yes I did that. I need the code for the Match Button. For when the User click on it, it can match the relevent data to the relevent clients.

Oh, you want to know what to put in the button click event handler.  You can cast the 'sender' into a Button, and then get parent information to determine the DataGrid item that you are working with, and then use FindControl to get a reference to any other controls for the current item, and then transfer values from one control to another.

Here is the code that I have for the Match Button. It's not working properly. Can you help?  

Private Sub btnMatch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnMatch.Click
        Try
            Dim row As DataGridItem
            Dim SqlHelper As SqlHelper
            Dim MyDataSet3 As DataSet = Nothing
            Dim connection As SqlConnection = New SqlConnection
            Dim SuppParams() As SqlParameter = New SqlParameter(4) {}
            Dim vsVendors As String = ""
            Dim oSessionInfo As SessionManager = New SessionManager
            Dim ds As DataSet = Nothing
            Dim vlfkCompanyID

            SuppParams(0) = New SqlParameter("@VendorCoID", SqlDbType.Int)
            SuppParams(0).Value = vlfkCompanyID


            connection.ConnectionString = Configuration.ConfigurationSettings.AppSettings("ConnectionString")
            MyDataSet3 = SqlHelper.ExecuteDataset(connection, CommandType.StoredProcedure, "spSingleVendorMatchSearch", SuppParams)

            For Each row In dgSearch.Items
                Dim chkbx As CheckBox = row.FindControl("chkItemChecked")
                If chkbx.Checked = True Then
                    vsVendors = vsVendors & row.Cells(0).Text & " ,"
                End If
            Next

        Catch ex As Exception
            Throw ex
        End Try

    End Sub

Try this, and let me know what you get:

Dim btnMatch As Button = CType(sender, Button)
Dim parentType As String = btnMatch.Parent.GetType().Name
Dim grandParentType As String = btnMatch.Parent.Parent.GetType().Name

Put that in the btnMatch_Click event:

Private Sub btnMatch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnMatch.Click

Dim btnMatch As Button = CType(sender, Button)
Dim parentType As String = btnMatch.Parent.GetType().Name
Dim grandParentType As String = btnMatch.Parent.Parent.GetType().Name

...

Now, that is a change of gears (GRIND)!!

Configuration.ConfigurationSettings.AppSettings("ConnectionString")

I would use this instead:

    ConfigurationManager.ConnectionStrings("ConnectionString").ConnectionString

That would mean that the connection string would need to be in the <connectionStrings> section in the config file.
