The problem I am facing is that when there is validation on a page and I am trying to display a model pop-up, the pop-up is not getting displayed. And by using fire-bug I have noticed that an error is being thrown.
The button that is used to display the pop-up has cause validation set to false so I am stuck as to what is causing the error.
I have created a sample page to isolate the problem that I am having, any help would be greatly appreciated.
The Error
function () {Array.remove(Page_ValidationSummaries, document.getElementById("ValidationSummary1"));}(function () {var fn = function () {AjaxControlToolkit.ModalPopupBehavior.invokeViaServer("mpeSelectClient", true);Sys.Application.remove_load(fn);};Sys.Application.add_load(fn);}) is not a function
