Hi

We have an urgent issue with the WebDataGrids in IE 8 (version 8.0.6001.18702) on XP.  We are using IG controls 13.1.20131.2107 with .NET 4.0

It occurs on pages which have a validator on one/more fields of a WebDataGrid but does not happen consistently.  If we simply swap between two pages using our menu it will happen on one of the pages after a while - sometimes the first time we swap, other times it takes 3 or 4 clicks between the pages.

The error occurs on the last line of this function from ScriptResource.axd file and happens because control.Validators is null.

function ValidatorHookupControl(control, val) {
    if (typeof(control.tagName) != "string") {
        return;  
    }
    if (control.tagName != "INPUT" && control.tagName != "TEXTAREA" && control.tagName != "SELECT") {
        var i;
        for (i = 0; i < control.childNodes.length; i++) {
            ValidatorHookupControl(control.childNodes[i], val);
        }
        return;
    }
    else {
        if (typeof(control.Validators) == "undefined") {
            control.Validators = new Array;
            var eventType;
            if (control.type == "radio") {
                eventType = "onclick";
            } else {
                eventType = "onchange";
                if (typeof(val.focusOnError) == "string" && val.focusOnError == "t") {
                    ValidatorHookupEvent(control, "onblur", "ValidatedControlOnBlur(event); ");
                }
            }
            ValidatorHookupEvent(control, eventType, "ValidatorOnChange(event); ");
            if (Page_TextTypes.test(control.type)) {
                ValidatorHookupEvent(control, "onkeypress",
                    "event = event || window.event; if (!ValidatedTextBoxOnKeyPress(event)) { event.cancelBubble = true; if (event.stopPropagation) event.stopPropagation(); return false; } ");
            }
        }
        control.Validators[control.Validators.length] = val;
    }
}

NOTES:

• The validators work perfectly well on the grid if we actually make changes to the data.
• This error occurs without changing any data.  Ie, we load the page, then we simply click a menu to go to another page.  No data is changed in the grid.
• This only happens in IE8.  We can click between the pages 100 times in IE 9 and it does not occur (yes, I actually did this)

There is an "IF" block above the line which has the problem checking if the object is undefined - if (typeof(control.Validators) == "undefined") should this be also checking whether control.Validators == null??

Are we able to edit this function ourselves somehow to add this to the IF statement to see if it fixes the problem?

Any help much appreciated
