[Mono-dev] Postback on Custom Controls

[Juraj Skripsky]

Thanks for the test case! I'll look into it.

Maybe you should have a look at the source code of WebControl:
http://svn.myrealbox.com/viewcvs/*checkout*/trunk/mcs/class/System.Web/System.Web.UI.WebControls/WebControl.cs?rev=57676

There you can see that Render() calls RenderBeginTag() which in turn
calls AddAttributesToRender(). This method is overridden in LinkButton
and adds the __doPostBack stuff.
