I have been trying for 3 days to get a correct asp.net postback event for some asp.net controls put inside an Ext.Window... no success...
If we put a LinkButton in the window it does do the callback (of course 'cos its calling __doPostBack() too)
So first question : why does the UseSubmitBehavior is compulsory for ASP:Button within Ext Window ?
Second, I decided to add a ASP:TextBox within the window, and code a simple Button1_OnClick server side event handler where I just read the value of the textbox... and it is always empty !!!
so, second question : why can't we get the posted values of .net webcontrols ?
