Question

Maybe I’m searching with the wrong keywords, but I can’t find a solution to this.

I’ve got an ASPX page on which, within an <asp:Repeater> I want to insert a button (per item) that will:

1. ask (JS ‘confirm’) the user if they really want to proceed, then
2. call a method on the page class passing in the ID (Guid) from that item.

I can do 1 or 2, but can’t figure out how to call back into the page method from JavaScript.

I’ve tried turning on the EnablePageMethods in the ScriptManager, but that didn’t seem to do what I expected — calling PageMethods.Blah(...) did not seem to have any effect.

Are there any ready examples? In fact, the confirmation string is the same for every entry.

Answer 1

here’s what you need to do:

1. make sure your button has runat=’server’
2. in that button, add onClientClick=’javascript:return confirm(‘Are you sure?’);’

3. call your SERVER SIDE code from onClick even of the button

   <asp:Button id='Button1' Text='Do Stuff' OnClick='YOUR SERVER SIDE METHOD'       onClientClick='javascript: return confirm('Are you sure?');' runat='server'/>
