Hi all I got the answer. By setting the DataKeyNames we can make a auto genereted column read only.

thanks satip but I am unable to fiend what I am looking for. My problem is, I can not find the control in auto generated column in edit mode because I don’t know the control id the text box is auto generated. I want find it in RowEditing event Thanks & regards smruti

Dear Asithangae Thanks for your repay , of course I can use js to validate but it should also work for requiredfieldvalidation control. As I am using .clientId which return the client side id that is id in the browser. Please let me know if there any way out. Regards Smruti:) smruti

Hello. Do you have another "TextBox1" somewhere on your page? Perhaps in the Master page itself? If so - ASP.NET renames the controls in order to get a unique ID. It should automatically rename your RequiredFieldValidator1 reference to the control as well. But perhaps this does not happen as expected. Anyway you should go check it out. I've found the best way to debug this, is to try and rename your control to something logic eg. "txtName" - that way you ensure, that you decide the names, and not Visual Studio, because, well, it's best the other way around. ;-) Best Regards Soeren
