Hello,

If i am not wrong then you are using the onsubmit() method on the same function because of which your program is not responding. Its better to run it in the separate function to work properly to produce the the proper outcome. Here i am giving the code which will display the onsubmit() method in the separate function. So try your luck this time with the code given below.

form runat="server" onsubmit="frmfirst_onsubmit()" id="Default">
function frmfirst_onsubmit()
{
var _frmObj = document.getElementById('Default');
_frmObj.style.cursor = 'hold';
ShowXHideY('Hold for a moment', 'MainTable');
}

It is an Internet Explorer error caused by the attempt to access the non-existent style collection of document object. It can be corrected by changing a line in the "getOffsetParent' function by securing the "getStyle" from being called the document object.
Here is the example to change the line:

while ((element = element.parentNode) && element != document.body)
After converting the code:
while ((element = element.parentNode) && element != document.body && element != document)

First make sure that the ID of object which you are using is the object of the showError. It is because if you are using the UserControl or the MasterControl and then it is the server side control then ID could be recognized by the containers ID. For confirmation purpose to avoid this just right click on the page and go to the view source of the HTML and look for the control and check the generated ID property. That all i know about this.

Hope it will work. Thank you.
