customValidation control.
-
I have a drop down list in my asp page. when I selectg an irem and click on a button it appears in the Grid view. But when I again come to the same page and click on the same item from Drop down list it and click on button it again add the same item onin the Grid view. So I need some validatiobn that if this item appears in Grid view Don't add in the Grid view. I can use customValidation control. But I don't know how to use it.

You can aslo accomplish it by clearing DropDownlist item Before adding new Item. Call this
dd.Items.Clear();Before adding new Item. Best Regard Pathan---------------------------------------------------
