Setting SelectedDate In Edit Mode via CodeBehind

[Shawn]

I have a grid that displays its details in a Nested FormView.  When in EditMode I am trying to set a RadDateTimePIcket selecteddate property to the database column IF it has one.  Some have no value so I want it to default to Now() or NOTHING.

I am getting a "Object reference not set to an instance of an object." error when trying to do it like this:

ElseIf (e.CommandName = "Edit") Then

            Dim Event_Control As RadDateTimePicker = form_AppNotes.Row.FindControl("txt_event_date")

 -->Dim Event_Date As String = (TryCast(form_AppNotes.Row.FindControl("txt_event_date"), RadDateTimePicker)).SelectedDate.ToString

            Event_Control.SelectedDate = IIf(GenericFunctions.DoIExist(Event_Date) = False, Now, FormatDateTime(Event_Date))

        End If

It does not like the line I arrowed to above.  What am I missing here?!?

<telerik:RadDateTimePicker ID="txt_event_date" Runat="server" Skin="Sunset" SelectedDate='<%# Bind("event_date") %>'>

Hello Shawn,

You can access the RadDatePicker from the Edit From Template in the ItemDataBound using the following code:

VB:

Protected Sub RadGrid1_ItemDataBound(sender As Object, e As GridItemEventArgs)
    If TypeOf e.Item Is GridEditFormItem AndAlso e.Item.IsInEditMode Then
        Dim editItem As GridEditFormItem = DirectCast(e.Item, GridEditFormItem)

        Dim Event_Control As RadDatePicker = DirectCast(editItem.FindControl("txt_event_date"), RadDatePicker)
    End If
End Sub

Also refer to the following documents:

Thanks
