                <ColumnValidationSettings>
                    <ModelErrorMessage Text="" />

Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load
    Dim c As Integer

    c = RadGrid1.MasterTableView.Items.Count

End Sub

Protected Sub Page_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreRender
    If (RadGrid1.MasterTableView.Items.Count > 0) Then
        If (RadGrid1.SelectedItems.Count = 0) Then
            RadGrid1.MasterTableView.Items(0).Selected = True
        End If
    End If
End Sub

Hi Aykut,

I guess you want to keep the first row selected during page load.Please put the code in the OnPreRender event of the radgrid.

VB:

Protected Sub RadGrid1_PreRender(sender As Object, e As EventArgs)
    If (RadGrid1.MasterTableView.Items.Count > 0) Then
        If (RadGrid1.SelectedItems.Count = 0) Then
            RadGrid1.MasterTableView.Items(0).Selected = True
        End If
    End If
End Sub

Thanks,
Shinu
