hmm,but  what about the div not creating dynamicaly on screen
Suthish Nair16y agoPosted Nov 9, 2010, 11:19 PM
Ok, you cannot do Response.Write in update panels
EM
erum mirza16y agoPosted Nov 9, 2010, 8:40 PM
well nair i commented  the line 

'Response.Write(RadioButtonList2.SelectedValue) 

and i m not getting this error but div is not created dynamically means not showing any thing on screeen 
Suthish Nair16y agoPosted Nov 9, 2010, 11:30 AM
am not saying updatemode is the solution.

did you copy the code and tried to run on an .aspx page.

its clearly saying what the error is..
EM
erum mirza16y agoPosted Nov 9, 2010, 9:53 AM
thanks nair for ur reply   i set 

updatemode="conditional" but gettinga n error  when clcik on radiobuttlist2 

 

Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.
Details: Error parsing near 'tion||WebForm1.aspx|'.
Suthish Nair16y agoPosted Nov 9, 2010, 3:05 AM

also, always use updatemode="conditional" for update panels
