in your page you dont have "txtbox" as name for paritcular control

have you changed the file names individually..
means for .aspx and .aspx.cs seperately

give the error what you have got exactly

Thank For reply..
My error is txtname does not exist in current context and many more controls giving same error.

hitech_s 27-Sep-11 8:34am

are you creating user control..?

abhiamity86 28-Sep-11 2:17am

Yes, it is user control.
And above files are .ascx and .ascx.cs files.
by mistake it has been metined there as .aspx and .aspx.cs.

Hi,

place break points in page load then check in what line it raises that error

and place your code in pre tags for better readability

All the Best
