Hi all,

The issue is fixed and will be available as of R1 2021. 

Then, if you want to show the status bar during export and hide it using the cookies approach, you would need to improve the OnCommand handler as follows:

function OnCommand(sender, args) {
                
    if (args.get_commandName().indexOf("Export") > -1) {
        // show status panel
        var label = $get(sender._statusLabelID);
        if (label)
        {
            label.title = sender._loadingText;
            label.style["visibility"] = "visible";
        }
        pollingAPI.startPolling(function (cookieMessage) {
            //alert(cookieMessage)
            clearStatusPanel(sender)
        }, 200);
    }
}

Also, you would be able to use any loading panel instead of the status bar when exporting, e.g. RadAjaxLoadingPanel as explained here:

Hello Wilberto,

The following workaround based on Use cookies to help execute custom JavaScript after a file starts to download can be used: 

<telerik:RadGrid ID="RadGrid1" runat="server" OnItemCommand="RadGrid1_ItemCommand"  ShowStatusBar="true">
   ...
    <ClientSettings>
        <ClientEvents OnCommand="OnCommand" />
    </ClientSettings>
</telerik:RadGrid>

protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
{
    if (e.CommandName.Contains("Export"))
    {
        // add cookie to know the file begins downloading
        HttpCookie myCookie = new HttpCookie("file-download");
        myCookie.Value = "The file started downloading!";
        HttpContext.Current.Response.Cookies.Add(myCookie);
    }
}


<script src="polling-api.js"></script>
<script>
    function OnCommand(sender, args) {
        if (args.get_commandName().indexOf("Export") > -1) {
            pollingAPI.startPolling(function (cookieMessage) {
                //alert(cookieMessage)
                clearStatusPanel(sender)
            }, 200);
        }
    }
 
    function clearStatusPanel(grid) {
        var label = $get(grid._statusLabelID);
        if (label) {
            label.title = "";
            label.style["visibility"] = "hidden";
        }
    }
</script>
