Forms Data Controls :: How To Validate Checkbox In DataList

Apr 17, 2010

I have <asp:Button ID="btnDelete" ..../> and <asp:DataList ID="lstOrder"..../>

"lstOrder" has <asp:CheckBox ..../> for each "lstOrder" item. I am binding "lstOrder" to DataTable at run time (DataTable is being created dynamically"

"btnDelete" first loops through the "lstOrder" and stores the indexes of items which are marked(checked). Next rows are deleted from the DataTable and "lstOrder" is binded again.

I don't want to postback if none of the items are marked in the "lstOrder"

How to validate ?
