I get one postback, for every time I've opened a RadWindow

Hi,

I am opening a RadWindow that calls .ajaxRequest in a javascript function, onclientclose.

I open the window, do NOTHING, then close it by clicking on the close button in the upper right hand corner of the dialog.

My javascript function runs, I get a postback to my main aspx page, and my AjaxRequest method runs as expected.

However, if I then open the RadWindow and close it again, I then get TWO postbacks to my main page, and after the second one my AjaxRequest method runs as expected.

If I open / close the RadWindow N times, I get N number of postbacks to my main page, and after the second one my AjaxRequest method runs as expected.

I'm sure this is something I'm screwing up. It is like there is another instance of the RadWindow created every time I open it, and for each instance I get a postback.

Q. Why am I getting one postback per time I've opened the RadWindow?

Ideas?

Thanks,
Brent

select node when right-click in multi-contextmenu treeview

Hi,

I want to select the node when I right click on the node (to show the contextmenu). Then I use the following javascript code to achieve this:

function onClientContextMenuShowing(sender, args)
        {
            var treeNode = args.get_node();
            treeNode.set_selected(true);
        }

It works fine when I have only one contextmenu for the treeview. But when I using the code on a RadTreeView with two contextmenu, it does not work.

Could anyone tell me how to solve the problem?

Thank you!
Hank

Grid Filtering & genral question

Hello, I am trying to play with the grid and have a few questions. I am completely new to the grid...

1)
I am trying to acheive filtering on multiple datafields. This is what I have done..
I created a custom UserControl which has a certain display and shows data for 4 datafields... I created a GridTemplateColumn that contains the customUserControl. Now I can filter on 1 datafield by setting its DATFIELD property, but what I really want is try to Filter on all 4 fields that are in the Custom UserControl.. So my condition should either Field1 or Field2 or Field3 or Field4 for the usercontrol.. Can I implement an event and get access to that datarow, if so which event?

Can I acheive this? Any help would be greatly apprecaited as I need to get this piece done..

2)
I want to show the Filtering options, but dont want to show the column headers? Can I do this.. When I set ShowHeader it also hides the filters...

Thanks
Tom

Add node to menu plugged on sitemap

I have a menu control that is plugged on a sitemap.

I was wondering if i can, once it's loaded, add a new node at the end of my menu in the code.

I have set the property AppendDataBoundItems but i can only add the node at the beggining of my menu. This is not nice because i want it at the end

thx in advance

Group/UnGroupOnColumnDoubleClick

Requirements
RadControls version	2008.01.0415.20
.NET version	2.0
Visual Studio version	2005
programming language	C#, Javascript
browser support	all browsers supported by RadControls

PROJECT DESCRIPTION

This project illustrates how to preform Grouping/UnGrouping in RadGrid on double clicking the column header. The task is achieved by adding an OnColumnDblClick client event for the Grid and performing a PostBack from the client side. Then in the RaisePostBack event Grouping/UnGrouping can be performed.

Resize Image in TreeView Node?

What is the CSS tag I need to look for so I can resize an image when loaded into a treeview node? I see the .rtLI, but i am assuming that is for the entire line item. Is that the tag I should use to resize the node?
