Using ASP.NET 4.0
Bit of a strange one here, my code works but I don't know why!
So I have some HTML like so:
<asp:Repeater runat="server" ID="uxMyRepeater" ClientIDMode="Predictable">
<ItemTemplate>
<asp:Button runat="server" Text="Submit" />
<asp:HiddenField runat="server" ID="uxIsVisibleHiddenField" Value="0" />
</ItemTemplate>
</asp:Repeater>
And the back end:
Protected Sub uxMyRepeater_ItemCommand(source As Object, e As RepeaterCommandEventArgs) Handles uxMyRepeater.ItemCommand
uxIsVisibleHiddenField.Value = "1"
End Sub
So for some reason this works, usually I would expect to have to declare uxIsVisibleHiddenField in uxMyRepeater_ItemCommand like so:
Dim uxIsVisibleHiddenField As HiddenField = DirectCast(e.Item.FindControl("uxIsVisibleHiddenField"), HiddenField)
But in this particular case it works without the declarative statement. Can anyone shed any light on why it would do this?
Please note this is sample code only, not my actual code.
EDIT
Forgot to mention there is an UpdatePanel around each RepeaterItem, removing this causes Visual Studio to give me an error that'd I'd expect: 'uxIsVisibleHiddenField' is not declared. It may be inaccessible due to its protection level.
