Code Behind

Private Sub WireEvents()
        AddHandler ddlCheck.SelectionChanged, AddressOf ddlCheck_SelectionChanged
        AddHandler ddlCheck.ValueChanged, AddressOf ddlCheck_ValueChanged
    End Sub


    Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init
        WireEvents()
        End Sub

   Protected Sub ddlCheck_SelectionChanged(ByVal sender As Object, ByVal e As Infragistics.Web.UI.ListControls.DropDownSelectionChangedEventArgs)
        Dim i As Integer = 5
    End Sub

    Protected Sub ddlCheck_ValueChanged(ByVal sender As Object, ByVal e As Infragistics.Web.UI.ListControls.DropDownValueChangedEventArgs)
        Dim i As Integer = 5
    End Sub

I put break points on the Int=5 lines and neither of them are hit at any time no matter what. I followed the example on the samples site for ServerEvents and still nothing. Also one other thing, 

<ig:DropDownItem Selected="true" Value="" Text="&lt;Choose Check&gt;" /> does not show up in the drop down. I would like this to be the initially selected item. This item should not be in the template when you actually click the drop down to open it. I tried tapping into DataBound event

Public Sub ChecksDataBound(ByVal sender As Object, ByVal e As EventArgs)
        'ddlCheck.Items.Insert(0, New DropDownItem("<Choose Check>"))
    End Sub

That add the item the way I like, except that it ALSO creates a blank template item which is definitely not what I want. Any help is always appreciated.

 

Code On,
