Can u think of any soln for this so that hiddenfield is retrieved..Do u think there is problem in the Program.ascx..Just check it if i have put form and div correctly... And also i have not pasted all my code but only the code that is neccessary...Here the program which i am doing goes like this..If user does any changes in the drop-downlist,It should notify to the user..For that m using hiddenfield concept but its not working ..

the better approach as i look to this is to have a property in the usercontrol and by default have that false and once user changes the dropdown then set that to true...
and properties could be accessed from aspx.cs or ascx.cs...
