OnFocus function does not work

<asp:HiddenField ID="hdnBlockRefresh" runat="server"/>

<script type="text/javascript">
function BlockGridRefresh() {
         document.getElementById('hdnBlockRefresh').Value = '0';
            alert(document.getElementById('hdnBlockRefresh').value);
        }
        function GridRefresh() {
            document.getElementById('hdnBlockRefresh').Value = '1';
        }
</script>

And

txtTechnician.Attributes.Add("onfocus", "BlockGridRefresh()");
txtTechnician.Attributes.Add("onblur", "GridRefresh()");

I have a griView with many textboxes with the same id and i want to set the hiddenField value when is no focus one of them.

If a pun alert in BlockGridRefresh is displayed over and over again...and my hiddenField value is not set. Why this is happening?

Re: OnFocus function does not work

Hi,

U have used .Value but javascript is case sensitive U need to use .value ( lowercase 'v').

document.getElementById('hdnBlockRefresh').value = '0';

and make sure the Id name is same as client ID

Re: OnFocus function does not work

Hi,

I think until you submit the form, you can't access the Hidden field variable value!

What you can do is, assign the value to a temp variable and access it!

Hope it helps u...
