I'm  using a user control in my web application and on its Page_Load i'm using the following code

ClientAPI.RegisterPostBackEventHandler(Me, "CaseAssigned", AddressOf CaseAssignedSrv, False)

When i run the app i get the following error

'System.Web.UI.ResourceBasedLiteralControl' does not allow child controls.

If I try Me.Page instead of Me in the first parameter i get another error

A control cannot modify its parents' control collections.

Thanks in advance!

I can't find neither ClientAPI.NeedsDNNVariable nor ClientAPI.RegisterDNNVariableControl methods on 3.2.2 version of DotNetNuke.WebUtility

Are this features going to be available only in the next version of DNN?

I already solved this problem by adding on the Page's PageLoad the following code

ClientAPI.RegisterClientVariable(Me, "_temp", "", True)

which i suppose is the same as adding the '__dnnVariable' input control in the page.

Thanks for your response
