Hello,

We have a problem with RadTreeView with Context Menus running in the PanelBar. Every time menu gets repainted (right mouse click, etc.) we are getting a JavaScript error. The same tree with the same menus running outside the PadPanelBar functions fine.  The Context Menus both populated in runtime and static – the same behavior.

Details:

Version: .NET 3.5 ; Telerik  ASP.NET controls  for  3.5 (2008.1.619.35)

The error is in the code (js):

Telerik.Web.UI.RadMenu._getMaxRootItemWidth=function(_43){

var _44=Telerik.Web.UI.RadMenu._getChildListElement(_43);

var _45=_44.childNodes; ß-this line, 'childNodes' is null or not an object

_43- is a Context Menu element, at the time of the error it is empty, though after you ignore the errors (there can be a number of them ,all the same) the context menu displays just fine.

_44 is null

Some call stack details (not every call stack element, just those seem important)

Called from: var _3e=Telerik.Web.UI.RadMenu._getMaxRootItemWidth(_3d);

Called from: if(this._flow==Telerik.Web.UI.ItemFlow.Vertical){

Telerik.Web.UI.RadMenu._adjustRootItemWidth(this.get_id());

} –tried to set Flow=”Horizontal” in the menu or in the DefaultSettingsGroup- didn’t help

Called from: _7.repaint();

Called from: $telerik.repaintChildren(this); where “this” is a PanelBar – this.element.id=     ctl00_ContentPlaceHolder1_rpbNav

Called from: this.get_panelBar()._callRadShow();

Called from:

if (!initialLoad) {

            // If this isn't the first page load (i.e. we are doing an async postback), we

            // need to re-raise the Application's load event.

            Sys.Application.raiseLoad();

        }, which is in  MicrosoftAjaxWebForms.js

Looks like the conext menu gets interrogated by repaint from RadPanleBar before it gets populated.

Part of .ASPX page (it is a content page within master page):

For this particular page menus are populated dynamically, although we have the same problem in another tree with a static context menu.

Please help. Our release is closing and we really like the functionality of the PanelBar and would like to include it into the released version.

Thanks a lot,
