I have a Winform user control hosted in IE. the control and asp.net page wrote in .net 2.0.
the control looks Ok on the asp.net page.
the problem is on the page I have a button to trigger a javascript function. that javascript will pass a value to Winfom control by using property defined in winform user control. but that value never been set properly. also I try to call the control's
public method from Javascript function. and I got Javascript error :" Object doesn't support the property or method".
anyone got idea what's going on please help.
