Hi,

I have a requirement where Root Category Node should always be in Expanded mode in RadTreeView control.
I have written the code to show it in expanded mode when RadTreeView is loaded first time but to give it a better meaning I also need to remove the Collapse Icon from the Root Node which is always present there.

I tried updating Node element from code behind but could not find any property like "Collapsable" which I can set to false for this particular node.

Please let me know if there is any attribute or customized code exists for this.

Thanks in advance

This Code Project: http://www.telerik.com/community/code-library/aspnet-ajax/grid/excel-like-radgrid.aspx

It works by itself when I run it, but I can't get it to work once I have converted it over to using a LinqDataSource on the page.  Do you guys have an example of this, but using modern constructs like LINQ and LinqDataSource?

Thanks!

Hi,

We are using the Grid with a LinqDataSource and whenever we group by a field the group footer summaries are shown for a per page basis (when expanded), but when we collapse the group only the visible records are collapsed and not the entire group across pages, Can this functionality be achieved, if so How ?

Hi,

Spent ages trying to work out why my RadAjaxLoadingPanel isn't displaying for ajaxified FormViews. Turns out I had the RenderOuterTable property set to "false" on each of the FormViews.

Also notice you get the same problem if in .NET2, you use the CSS Friendly control adapters with FormViews.

Looks like unless you allow the Formview to render as a table, then the LoadingPanel doesn't display.

Has anyone found a workaround for this, either in code or CSS?

Cheers

The above code generate an error when the system try to execute the GetSecurityRoot method.
