Hi,

I have a treeview in which I load the first two levels server side on PageLoad. Children will be loaded using Webservice load on demand and it works well. I have one problem though, when handling the RadTreeView_OnContextMenuClicked event serverside, the e.ClickedNode property is null. So when clicking context menu items, the event fires but when I want to handle the c.clickednode its null. It works with the server side loaded nodes...

What am I missing?

Can someone help me with how I would display a processing message to my users?  I have a page that allows them to edit lots of items then I have to submit those changes to the database.  This can take up to a couple minutes depending on how many items they updated.  How can I give them a message to let them know that everything is working?

Thanks.

Hi all,
     I have a grid in which i have used commanditemdisplay. Can I hide it from the code behind. If yes how??
thanks for all replies

Hi,

I have a RadPanelBar, which includes several panelitems.  I put a radtreeview under each of the item. then add the first-level treenodes to them programmatically, and the node Expandmode has been set to "ServerSideCallBack" so that the second level node can be expanded on demand.

The program works ok but the only issue is the Scrollbar does not appear automartcally when I expanded the treenode and the content exceed the height. But if I set the Expand="True" and "Selected="true" at the panelitem then the scrollbar appear. But logically only one can be expanded and selected, how to fix this?

I am using the latest build (2012.3.1205.35) and tried on IE 9/Google Chrome, same result

I understand the part about RadAjaxPanel ajaxifying all controls within it's tags but does it ajaxify invisible controls? Say you have five asp panels within a RadAjaxPanel that you toggle visibility on based on link button clicks. If only one panel is visible at a time, does the RadAjaxPanel ajaxify ALL of the five panels' controls on say, a button click contained within the visible panel OR does it ajaxify just the panel that is visible and therefore just the controls contained within the visible panel?

I am having difficulty on a tooltip with grid and this grid has pagination.

Scenario:
Parent page -> radgrid with tooltip -> load ascx for tooltip
Tooltip (ascx) -> radgrid with pagination

If tooltip is shown and next page is clicked, nothing happens since it always call ajaxupdate and not the pagination event or the needdatasource event of the grid on the tooltip (ascx)

Kindly advise on this scenario.

Thanks.

Is there a way to configure the RadRadialGauge for quadrant-style or semi-circle gauges.  The Silverlight gauges have this option, but I don't see it for the ASP.NET gauge controls.
