Hi, I'm tryin' to do DragDrop in my radtree. I see it's different against system.treenoview, 'cause what I cade in treeview don't work iwith radtreeview. Ok, I'm goin' to investigate what's the matter. But now, I want to know how to implement DragDrop like the example show in the demo of controls. DragDrop that show a red righ-arrow (node in node), up-arrow (node up node) or down-arrow (node below node). How??

Thanks.

Hi, I'm developing under VISTA. Reading help from RadTreeNodeComparer, i saw this:

Target Platforms: Windows 98, Windows NT 4.0, Windows Millennium Edition, Windows 2000, Windows XP Home Edition, Windows XP Professional, Windows Server 2003 family

Is there any problem with VISTA?

I used the property builder tool and added a checkboxcolumn to my radgridview.  I want to have an picturebox in the column that will put a different image based upon some boolean value.

I have everything working, but I cannot get the control to be centered in the column.  I am adding the RadImageItem as such:


I'm sure that there is an easy way to do this, but I am not able to locate it.  The Alignment Properties do not seem to adjust this.

Thanks as always.

Hi,
I bind a List<T> to the grid and get the items displayed properly. When I want to add a new item into the list of items, I do that from the code - so, a user presses 'Add' button, and in the code I actually add an instance of type T into the list. However, the grid does not get updated with that new row. This is the code I use to bind:

List<T> myList = whatever;
GridInstance.DataSource = myList;

When I add a new item:

myList.Add(new T());

If I check GridInstance.DataSource right after I add an instance into the list, then I can see that the DataSource refers to the updated list, but the UI stays the same...

What should I do to update the UI in this case? Thanks!

Hi

I am using Telerik.WinControls.UI.RadGridView

I've got a bit of a problem I'm trying to work around. I'm hoping there's a much better way to do this..

I've got a DockingManager on my form, and I've assigned it the Office2007Black theme. I'm not entirely happy with it, so I want to edit the theme. Unfortunately, the docking manager smart tags don't allow me to edit the theme of the Docking Manager!

Not only that, but I can't figure out how to load the Office2007Black theme into the visual builder for the Dock Panel and Document Panel, so I'm left with trying to duplicate the look all over again.

Not only that, but in general I want to use my own customized theme for every single control, but have it based off of the 2007 theme with some minor tweaks. How would I go about making sure of the following:

1. All controls are themed in all my forms, consistently across the entire application
2. Any controls I add to my form automatically take on the theme of the application, without me having to manually go in and set every single theme property
3. Any controls that I may not have used yet (say, a RadHScrollBar) automatically can be set to my new theme, without mucking around inside the theme (essentially, how to copy the *entire* Office2007Black theme, for *all* controls, once. Not every time I add a new control).

Additionally, 2 more questions..

4. Anyone have any sample buttons for the title bar that actually work with the Office2007black theme?
5. Where on earth do you find the Visual Style Builder Options? I can't figure out where you set the smart buttons & outline options..

Hello,

other than expected setting the LayoutTree prop with an saved tree string doesn't restore the layout. It just saves the value to an private field.

How is it intended to reload a layout persistet from the LayoutTree property? I suggest there should be a loadXML not only for file but also for string and the LayoutTree property should only offer a getter.

Thx

I have the necessity to put a bmp in the X axis because I must do a Chart for a spectrum graph.
I think can be useful can put a property that use a picture instead a normal line in the X axis.

Maybe if you want do a full kind of chart it work in this way

the Y axis go to 0 to 100 and the X axis from 350 to 750 with step 10 or 20 and in the X axis there is the picture of the gamma colors . If you need I can send a Image with the control because I made it in vb6 but with a picturebox.
