AJAX-refreshing progressArea in grid

[Oscar]

Hello
I have a progress monitoring screen with a radGrid that lists processes.
One of the grid columns contains a progressArea that shows process progress (from 0 to 100%) (see attachment)
To refresh the page I use the following

Page.ClientScript.RegisterStartupScript(

Me.GetType(), "refresh", "window.setTimeout('window.location.reload(true)',10000);", True)

This causes the entire page to reload every 10 seconds, which is annoying,  I want just the progressareas to refresh, but cannot find how.
Thanks for any help

Hello Oscar,

I suggest you to use setInterval() method to perform AJAX request on given interval. You could do this by applying the following JavaScript:
JavaScript:

<telerik:RadCodeBlock runat="server">
    <script type="text/javascript">
        $(document).ready(function () {
            setInterval(alertMessage, 1000);
        });

        function alertMessage() {
            $find('<%=RadAjaxManager1.ClientID %>').ajaxRequest("refreshLabel");
        };
     </script>
</telerik:RadCodeBlock>

You have to set the OnAjaxRequest event handler and update the RadGrid control:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" OnAjaxRequest="RadAjaxManager1_AjaxRequest">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="RadAjaxManager1">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="RadGrid1" />
            </UpdatedControls>

       </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManager>

In code behind you shoud find the control which you want to update and make the appropriate changes. 

protected void RadAjaxManager1_AjaxRequest(object sender, AjaxRequestEventArgs e)
{
    if (e.Argument == "refreshLabel")
    {
        foreach (GridDataItem item in RadGrid1.MasterTableView.Items)
        {
            Label label = item.FindControl("Label1") as Label;
            label.Text = DateTime.Now.ToString();
        }
    }
}

I prepared a small sample and attached it to this thread. I hope this helps.

Kind regards,
