Discuss "Reference User Control in nested repeater" in the .Net Development forum.

Hi again

the scenario:
my user control is loaded into a ModalPopupExtender via OnItemDataBound of
a repeater sitting in the diaplay Panel of the ModalPopup.

inside that panel is an update button which fires an event, which in turn fires
an update event in my user control's code-behind.

All of this is happening within a nested repeater (grandchild), and this is what
makes it difficult to reference controls etc.

here's my logic:
the sender is the 'Update Button'
from there I can reference the Panel the button resides in
from there I can reference the Repeater that resides in the Panel.

this all works, so from there I wanted to reference my UserControl that
was in the repeater, but alas it doesn't find my UserControl.

my code for the Update event of my Update Button:
green = works
red = doesn't work

Code:

Public Sub ActiveSpecificationsUpdate(ByVal sender As Object, ByVal e As EventArgs)
        Dim myButton As Button = sender
        Dim pnlActiveSpecification As Panel = myButton.Parent
        Dim rpActiveSpecification As Repeater = pnlActiveSpecification.FindControl("rpActiveSpecification")
        If CType(ViewState("FormsArt"), String) = "1" Then
            Dim FormsArt As CustomControls_form_art = rpActiveSpecification.FindControl("FormsArt")
            FormsArt.SpecID = myParams.SpecID
            FormsArt.Visible = True
            FormsArt.Update_Form()
            ViewState("FormsArt") = "0".ToString()
        End If
    End Sub

any ideas?

You will need to search through the repeater items to find your user control. If the user control is in the same repeater item as the button that you clicked:

Code:

Public Sub ActiveSpecificationsUpdate(ByVal sender As Object, ByVal e As EventArgs)
    Dim btn As Button = sender
    Dim FormsArt As CustomControls_form_art = btn.Parent.FindControl("FormsArt")
End Sub

Or, you can try iterating through the repeater items:

Code:

Public Sub ActiveSpecificationsUpdate(ByVal sender As Object, ByVal e As EventArgs)
    For Each item As RepeaterItem in Repeater1.Items
        Dim FormsArt As CustomControls_form_art = TryCast(item.FindControl("FormsArt"), CustomControls_form_art)
    Next
End Sub

    For Each item As RepeaterItem in Repeater1.Items

    Next
