Reference UserControl handler from Page form codebehind file

Question

I have changed loading UserControl from declaration in page to codebehind file but now i cannot access the imagebutton handler event?

'This is Click event definition for UserControl control.
    Public Event Click As SlideShowClick

    Public Delegate Sub SlideShowClick(ByVal sender As Object, ByVal e As SlideShowImageEventArgs)


    Protected Sub imgSlideShow_Click(ByVal sender As Object, ByVal e As ImageClickEventArgs)
        RaiseEvent Click(Me, New SlideShowImageEventArgs(CType(sender, ImageButton), e.X, e.Y))
    End Sub



Now loaded in Codebehind

            Dim uc As ASP.WebUserControl2 = CType(Page.LoadControl(controlPath), ASP.WebUserControl2)


**uc.SlideShowClick = "SlideShow1_Click"**

the error states that this is a type and cannot be used as an expression

Hi @peter liles ,
You could use AddHandler.Just like this:
aspx:

 Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load  
        AddHandler SlideShow1.Click, AddressOf SlideShow1_Click  
    End Sub  

user control:

   Public Delegate Sub SlideShowClick(ByVal sender As Object, ByVal e As SlideShowImageEventArgs)  
    Public Event Click As SlideShowClick  
    Public Sub imgSlideShow_Click(ByVal sender As Object, ByVal e As ImageClickEventArgs)  
        RaiseEvent Click(Me, New SlideShowImageEventArgs(CType(sender, ImageButton), e.X, e.Y))  
    End Sub

How i resolved it was to add a handler to the page that reference the event.
I did try to send all relevant code but unfortunately it wont allow html code? and when i attempt sending a txt file it fails?
I am trying to build a slider from horizontal datalist. I am wondering if you may know about any available example scripts other than the popular JQUERY type. They appear to be an essential feature today.

Thanks for your support.

Hi @peter liles ,

uc.SlideShowClick = "SlideShow1_Click"

As I know,it can't use this in vb. Could you post all reference codes to us?
