Hi Uday,

Firstly, can you let me know if you are creating any dynamic controls in row updating event? And when it Gridview created? Are you creating it from code?

Generally ViewState stores control ID values during postback and these must match before and after postback. So if you are creating any controls dynamically , just make sure to give explicit IDs to those controls.

else, just could you copy and paste that event code here.
