Question

I have an update panel and inside the panel text boxes and buttons are available. Now I am using the jQuery Validation plugin, but the validation plugin is not working when it is used in the update panel.

For example:

function GetAddressTargetList() {
    var objArray = new Array();
    var objAddressElement = new Object();

    objAddressElement = new Object();
    objAddressElement.Id = "ddlAccType"; 
    objAddressElement.Rules = "required";
    objAddressElement.TargetControlType = "select";
    objArray[objArray.length] = objAddressElement;
    objAddressElement = new Object();
}

and in the page level (.aspx)

$(document).ready(function () {
    GetAddressTargetList();
});

function pageLoad(sender, args) {
    // To load the tooltip in update panel
    if (args.get_isPartialLoad()) {
        GetAddressTargetList();
    }
}

How can I get the validation when I am using the update panel working?

Answer 1

I think that you have forget to initilize the pageLoad

Add this on your code:

$(document).ready(function () {
    Sys.WebForms.PageRequestManager.getInstance().add_pageLoaded(PageLoaded);
});

function PageLoaded(sender, args) {
    GetAddressTargetList();
}

Update

I have update the pageLoad to PageLoaded, to avoid conflict after the comment of the rs. In my opinion the UpdatePanel have a custom way to handle the events and what we try here is to trigger the event on javascript after the UpdatePanel Updates the content.
