Hi

I have a grid with a GridDropDownColomn and i tried to add a requiredFieldValidator to it, but it seems that i"m missing something.... First i use RadGrid1_ItemDataBound to add a "Please select item" in my RadComboBox, after that in the RadGrid1_ItemCreated, i'm looking for my radcombo and i associate the RequiredFieldValidator to it but it does'nt works. I assume that the requiredFieldValidator check for the selected text and not the value , so how i can make it works ? There is my code snippet :

Private Sub RadGrid1_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles RadGrid1.ItemDataBound

TypeOf e.Item Is GridEditableItem AndAlso e.Item.IsInEditMode Then

    Dim Combo As RadComboBox = TryCast(e.Item.FindControl("RCB_ResponsibleID"), RadComboBox)

    Combo.Items.Insert(0,

New RadComboBoxItem(Resources.Resources.GRID_SELECT_RESPONSIBLE, Nothing)

End If

End Sub

Private Sub RadGrid1_ItemCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles RadGrid1.ItemCreated

If TypeOf e.Item Is GridEditableItem And e.Item.IsInEditMode Then

Dim Combo As RadComboBox = TryCast(Item("ResponsibleID").FindControl("RCB_ResponsibleID"), RadComboBox)

Dim ResponsibleValidator As New RequiredFieldValidator

ResponsibleValidator.ControlToValidate = Combo.ID

ResponsibleValidator.InitialValue =

Nothing

ResponsibleValidator.SetFocusOnError = True

ResponsibleValidator.ErrorMessage = Resources.Resources.GRID_MUST_SELECT_RESPONSIBLE

Cell = Combo.Parent

Cell.Controls.Add(ResponsibleValidator)

End If

End Sub

Thanks in advance for your helps !

Select the RadScheduler in the designer, and click the ellipsis button on the ResourceTypes property in the property pane.

In the Resource Type Collection Editor, add a new resource type and configure it to bind to the second SQLDataSource:
