I have a repeater control that displays info. from a datatable. Each row in
the repeater has a checkbox. Also, I have a delete linkbutton outside the
repeater control. What I'm trying to do when the delete linkbutton is
clicked is get the SubscriptionID from the repeater control for each row in
which the checkbox is checked, then call a delete function. (See the code
for the .aspx and .aspx.cs below.)
The problem I'm having is that I cannot get the SubscriptionID for each row
in the repeater in which the checkbox is checked.
How can I cycle through each row in the repeater, check whether the checkbox
is checked or not, and, if it's checked, get the SubscriptionID for that row
in the repeater and send it to a delete function?
