[Ria12]

Hi...Guys

I have a created a Modal popup as a usercontrol .it also have a button .I want to handle button event of usercontrol on parent page by registering it on parent page.but it does not work properly...plz help me....

This wont work.

The button click event belongs to the user control, and so it has to be handled in the user control.

You could raise an event in your user control, which could be handled in your parent page, that indicates the button was clicked.

I told you.

In the button click event in the user control raise a new event.

If you don't know how to raise an event, check out this article on how to use events in .NET.

Change to Design view.
Double click on the Add button.

This will bring you to the VB.NET code and will automatically create a method that will handle the button click event. It will look something like the following:

Partial Public Class UserctrlPopl
    Inherits System.Web.UI.UserControl
 
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
 
    End Sub
 
    Private Sub AddButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles AddButton.Click
 
    End Sub
 
End Class
 

Once you're viewing the VB.NET code, declare a new event (maybe call it "AddClick" or something).

Partial Public Class UserctrlPopl
    Inherits System.Web.UI.UserControl
 
 
    Public Event AddClick As EventHandler
 
 
 
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
 
    End Sub
 
    Private Sub AddButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles AddButton.Click
 
    End Sub
 
End Class
 

In the method that handles the Button Click event you will raise the Add Click event:

Private Sub AddButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles AddButton.Click
 
    RaiseEvent AddClick(Me, New EventArgs)
End Sub

Now in your Parent page (your AdCreation page) you will have to handle the AddClick event (which you created) for your user control:

Private Sub PopUp5_AddClick(ByVal sender As Object, ByVal e As System.EventArgs) Handlese PopUp5.AddClick
 
    'Do Stuff Here
 
End Sub
