Hi all,
I have a CheckBoxList control which has about 10 items. I have set
autopostback=true and also set an eventhandler for
OnSelectedIndexChanged. The problem is I want to identify which
checkbox item caused the event to fire to perform some routines based
upon the value of that individual checkbox. How can I determine this?
For example, 5 of the 10 items maybe checked. However, when I uncheck
one, I want to perform some code based upon the value of just that 1
checkbox that fired the event.
You can't identify which checkbox caused the event to fire, because several
may be selected, and the control doesn't keep track of which one was changed
(it does keep track internally, but it doesn't let you know).
You'll have to store the list of selected items before the postback in
ViewState, and compare this with the selected items after postback.
Another option might be to replace the checkboxlist with a set of separate
checkboxes, and link them all to the same OnCheckedChanged handler. The
first parameter of the event handler (sender) will refer to the checkbox
that caused the postback.
