Status bar in self referencing grid visible on collapse but not expand

[Casey]

I have a self referencing grid inwhich the users want to see a processing status indicator. I have set the ShowStatusBar="True" and it appears to be working when the hierarchy within the grid is collapsed but it is not showing when the grid is expanding. There is nothing in the code behind that would stop this from appearing. Does anyone have any idea why this would happen? I need the status to display on both the expand and collapse.

Thanks!

Casey:

If you've not already seen this, there's a previous and recent forum thread that deals with the RadGrid Status Bar display that provides some insights:

ShowStatusBar=true not working

"... the status bar is intended primarily for use when RadGrid is used with RadAjaxManager to indicate when RadGrid is performing asynchronous AJAX requests."

It refers to the Hierarchical RadGrid online demo, which uses the Status Bar: Grid/Declarative Relations. In this demo, the status indicator only appears on collapse, and not on expand.

Apparently, there is no asynchronous AJAX request caused by the expansion.

Hope this helps!

I have code behind for the ItemCommand event for special processing on expand and collapse. Do you know of anything I could add into this to trick the grid into thinking there was an asynchronous AJAX request caused by the expansion?

Hi,

You could achieve your scenario by overriding the RadGrid initializeRequest function at the end of your page as it is shown below.

Telerik.Web.UI.RadGrid.prototype._initializeRequest = function (sender, args)
{
    var postBackElement = args.get_postBackElement();
    if (args.get_postBackElement() == this.get_element() ||
        Telerik.Web.UI.Grid.IsChildOf(postBackElement, this.get_element()))
    {
        var label = $get(this._statusLabelID);
        if (label)
        {
            label.title = this._loadingText;
            label.style["visibility"] = "visible";
        }
        this._isAjaxRequest = true;
    }
}
