Custom Templated Control not rendering controls correctly

Discussion in 'ASP .Net' started by, Apr 8, 2005.

  1. If I have an button inside a template for a custom control and use
    the code below, everything works fine and it generates the correct id and
    the button calls serverside click event as it should:

    _myTemplateContainer = New ContentContainer(Me)

    But if I use this code, it does not generate the unique ID and no serverside
    event will be called:

    Dim SB As New StringBuilder()
    Dim SW As New StringWriter(SB)
    Dim htmlTW As New HtmlTextWriter(SW)
    _myTemplateContainer = New ContentContainer(Me)

    If Not Me.Page.IsClientScriptBlockRegistered("MainWindow_" & Me.ID) Then
    Me.Page.RegisterClientScriptBlock("MainWindow_" & Me.ID, SB.ToString)
    End If

    The reason I was trying to do it this way is because I need the html of the
    template and some other html table code to be output to the top of the html
    page no matter where the actual custom control is sited and this was the
    only way I could figure out how to do that.

    Do you happen to know either of these answers:

    1. Is there something else I need to do to get RenderControl to generate
    proper ID's for control that exist on the template I am trying to
    render or is that just not possible.
    2. Is there another way I can make sure the output of the template always
    appears at the top of the page html?

    on the second code block, you don't add the template container to the
    Controls collection, that's the key part in when Page generates IDs for
    controls or when events are handled (for postback events, control would need
    to be in Controls collection at Page_Load at the latest)
