Hi,
You will need to handle the dialog's ClientSideOnAccept event. Inside that event handler you can then trigger a postback (you can use our ScriptEvent control to do that). It will be something like this:
Code: JavaScript
function on_dialog_accept()
{
eo_GetObject("ScriptEvent1").trigger("command_name", "command_argument");
}
Code: HTML/ASPX
<eo:Dialog ClientSideOnAccept="on_dialog_accept" ...>
...
</eo:Dialog>
You will then handle the ScriptEvent's Command event. The event arguments contains the command name and command argument you passed from your client side code when "trigger" method is called.
Thanks!
