Problem description:

The sample project contains a RadGrid (2 columns, 4 rows) that switches the  second column in the second and fourth rows in edit mode. The problem is that the first column does not display its value anymore (the value is "lost") while the second column is in edit mode. When I try to iterate through all the rows in Save_Command handler, I cannot get the value from these columns either.

I also have a second question: I would like to have an extra row to show the rollup on the editable column. Is it possible to have this total being updated as the user modifies the editable fields ?

Hi,
I am trying to retrieve data from a Rad Grid and inserting it into a dataset.
I am using the following code, but somehow it's not working.  I would appreciate it if you could tell me how I should get it to work.

Imports System.Data.SqlClient
Imports System.Data
Protected Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button2.Click
    Dim dt As DataTable = New System.Data.DataTable("Parameters")
    Dim ds As New DataSet
    Dim column As DataColumn
    Dim row As DataRow

    column = New DataColumn
    column.DataType = System.Type.GetType("System.String")
    column.ColumnName = "ParameterID"
    column.Unique = True
    dt.Columns.Add(column)

    column = New DataColumn
    column.DataType = System.Type.GetType("System.String")
    column.ColumnName = "ParameterDesc"
    column.Unique = True
    dt.Columns.Add(column)

    Dim PrimaryKeyColumns(0) As DataColumn
    PrimaryKeyColumns(0) = dt.Columns("ParameterID")
    dt.PrimaryKey = PrimaryKeyColumns

    ds.Tables.Add(dt)

    For Each Item In RadGrid1.MasterTableView.Items
        row = dt.NewRow
        row("ParameterID") = Item.Cells(0).Text
        row("ParameterDesc") = Item.Cells(1).Text
        dt.Rows.Add(row)
    Next
End Sub

Hi
I'm trying to add text description and linkbuttons to the groupdheaderitem of a grid.  I've added the controls in both ItemDataBound and ItemCreated grid events.   As per the samples I'm using 

DataRowView groupDataRow = e.Item.DataItem as DataRowView;

to access the data for the row, but this is not available on postback and I can't find another way to get the data for the row. 
I can't access the DatakeyValues in ItemCommand events as the itemindex isn't set on the group header.
Is there another way to customize the contents of the group header to include buttons that will postback correctly and allow me to identify the data row for the event?

I'm using the latest version of the grid. 

Thanks

Sub rcLt_ItemsRequested(ByVal sender As Object, ByVal e As RadComboBoxItemsRequestedEventArgs)

Dim comboBox As RadComboBox = DirectCast(sender, RadComboBox)

comboBox.Items.Clear()

comboBox.DataSource = itemsList

comboBox.DataBind()

'How do I retrieve the value of the textbox from before I entered edit mode?

End Sub

If somebody could give me some guidanc on this that would be great!

Thanks

Private Sub GridViewControl_ItemCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles GridViewControl.ItemCommand

If (e.CommandName = RadGrid.UpdateCommandName) Then

If (e.Item.GetType.ToString = "Telerik.Web.UI.GridEditFormItem") Then

Dim editedItem As GridEditFormItem = CType(e.Item, GridEditFormItem)

_Session(

"RadGrid.SavedOldValues") = editedItem.SavedOldValues

End If

End If

End Sub
