Kan godt se logikken, men det giver stadig fejl.! Forstår det simpelthen ikke.
WebUserControl giver følgende fejl:
Handles clause requieres a WithEvents variable defined in the containing type or one af its base type
i
Private Sub myEventHandle(ByVal logoUrl As String) Handles WebUserControl1.myEvent
Label1.Text = logoUrl.ToString
End Sub
og
myEvent giver følgende fejl:
"myEvent " is not an event of "WebUserControl"
i
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
RaiseEvent myEvent("Det virker")
End Sub
Her er hele koden:
aspx:
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" %>
