Checkbox List Item selected

When a user clicks a checkbox in my checkbox list I want to get the column numer they clicked on. For example, if they click the first box the number should be 0, the second box should be 1, and so on.

I tried this

rblAlerts.SelectedIndex

But this always return a 0 value no matter which check box is clicked. I have my code in the SelectedIndexChanged sub.

I am using VB .Net 2003.

Thanks

Do you have autopostback=True for the control?

Yes the auto postback value is set to True. If it wasn't then nothing would happen when the user clicked on the check box list. Like I said before I am getting the 0 value back no matter which check box the user clicks on.

Do any of your items share the same value, but different display text?

The event that handles the checkboxlist checkbox selection should have a... say, ItemIndex. So you can go

e.Item.ItemIndex or e.ItemIndex.

I don't think this works in the selectedindexchanged sub of either the radiobuttonlist control or the checkboxlist control. This is the only way that I could make it work.

if radiobuttonList1.items(0).selected = true then blah

if radiobuttonlist1.items(1).selected = true then blah

It would be more efficient if I could get back the slected value in one line of code than having to check for all possible radio buttons that could be selected.

I was wrong about the radiobuttonList. You can use radiobuttonList.selectedindex and that will give you the row that is selected.

However, I don't think this is possible for the CheckBoxList since more than one of these can be checked.

Yes, you can get the clicked item ID by accessing

Page.Request.Form["__EVENTTARGET"]

in the event CheckboxList_SelectedIndexChanged.
