I have a Winform user control hosted in IE. the control and asp.net page wrote in .net 2.0.

I have adjusted the trust level. the control looks Ok on the asp.net page.

the problem is on the page I have a button to trigger a Javascript function. the Javascript will pass a value to Winform control by using property defined in winform user control. but that value never been set properly. also I tried to call a control's public method from Javascript function on the page. I got a Javascript error :" Object doesn't support the property or method".

anyone got idea what's going on, please help!
thank
