Validating the page using JavaScript

I was using an AJAX tab control and wanted to validate the tab page before the switching away to another tab. It turns out there is a really easy way to do that – call Page_ClientValidate(“ValidationgGroupName”) from a javascript. If it returned true then the page/group is valid and I can allow the tab selection otherwise, I cancel the tab selection event. The code looks like this:

function TabSelecting (sender, eventArgs)


if (Page_ClientValidate(“CreateAccount”) == false)
