Blank Grid open in Insert Mode

[Elliott]

How do I set up a blank grid to start inserting data?  All I get is a blank screen
I am using VS 2010 with a trial copy of Telerik RAD controls

Hello Marianne,

Try the following code snippet in Page_Load event to set up a blank grid to start inserting data.

VB.Net:

 Protected Sub Page_Load(sender As Object, e As EventArgs)
  If Not IsPostBack Then
     RadGrid1.MasterTableView.IsItemInserted = True
     RadGrid1.DataSource = String.Empty
  End If
 End Sub

Regards,
Shinu.

thanks
I had dummied up a row in a DataTable and bound it to that
your solution is cleaner

however, I need to add some attributes to the newly created Edit row
would you know of an event on either the server side (preferable) or client side when a row opens to Insert?

Hello Marianne,

Please try the following approach:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
{
    if (e.Item is IGridInsertItem)
    {
        //...
    }
}

Protected Sub RadGrid1_ItemCreated(sender As Object, e As GridItemEventArgs) Handles RadGrid1.ItemCreated
    If TypeOf e.Item Is IGridInsertItem Then
            '...
    End If
End Sub
