How do you setup AddHandler on a parent form for a usercontrol event that is nested within a gridview?

I am trying to call a function using delegates in a parent form using AddHandler when a button click event is fired within a usercontrol that is on the form.

I have built a test application where I can get this working. The class on the parent form is:

Partial Class _Default
    Inherits System.Web.UI.Page
    Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
        AddHandler WebUserControl1.btnHandler, AddressOf test
    End Sub

    Public Sub test(ByVal strVacancyID As String)
       Response.Write("Called From TEST: " + strVacancyID)
    End Sub
End Class

The class on the User Control is:

Partial Class usercontrol_WebUserControl
    Inherits System.Web.UI.UserControl

    Public Delegate Sub OnButtonClick(ByVal strVacancyID As String)

    Public Event btnHandler As OnButtonClick

    Protected Sub btnTest_Click(ByVal sender As Object, ByVal e As EventArgs)
        RaiseEvent btnHandler("87")
    End Sub
End Class

However, in my current project the user control is nested within a gridview, when I try to add the "AddHandler" code the form can't "see" the user control, presumably because it is nested within the gridview.

How can I link the nested usercontrol to the AddHandler?

Many thanks,

Hi, you need to add the reference within the usercontrol tag:
<uc1:WebUserControl ID="WebUserControl1" runat="server" OnbtnHandler="test"/>

OnbtnHandler should appear in intellisense.

Hi vb jonas,
Thanks for the solution it works perfectly. I would never have figured that out myself. Thanks very much.
