I have a button on my page (with ajax ConfirmButtonExtender).
If on the page the user has selected over say, 1 million rows of data (this is calculated in the code-behind), when they then click on the the button, a pop up message will ask if they wanted to batch export the selection (i.e. Yes or Cancel).
So essentially, there are 2 possible scenarios.
1) Selection under 1 million rows.
Do NOT show the pop-up confirm message at all when click on the button - just run some codes in code-behind page. (i.e. Bypass the ConfirmButtonExtender msg).
2) Selection over 1 million rows.
A pop up message appears asking user to confirm if they'd like to batch export selection. User will select Yes or Cancel.
My question is - is it possible for the confirm message from ConfirmButtonExtender to be conditional (based on some calculation in the code-behind)?
How do I go about achieving this? Keep in mind that when user first clicks on the button, some codes will first need to run on code-behind to calculate the # of selections then decide whether to prompt the pop-up message.
Any ideas?
