Hi,

I'm using RadTreeView on WPF, .NET 3.5 SP1. My goal is to select an item in the treeview programmatically. For this purpose I tried the following:

tree.SelectedItems.Clear();

tree.SelectedItems.Add(item);

This works fine IF and ONLY IF this particular item was visible(expanded) at least once. Please help to resolve this issue. All I need is to select the item (no matter if it was expanded or not).

Thanks in advance,

Ruben.

Support for Item Selection

Hello,

I have a very simply implementation that embeds a radCarousel control on a grid and databinds the ItemSource to an Observable collection. The only way that I am able to select items is by clicking on the "scroll bar" buttons at the bottom of the control. I was under the impression that I should also be able to click on an item in the list as well to bring it to the front as the selected item. From the demos it appears that nothing special is required to support this functionality - am I missing something?

Thanks,
Mark.

BeginInsert() on child GridView

Hi,

Is there away to call the BeginInsert() method on a child grid in a heirarchical grid view? It works fine for me on the master, but I cannot find a way to make it apply to the child grid.

Any input would be appreciated, I couldn't find any forum posts and the documentation isn't really clear on this.

Thanks,
Marty

The type or namespace name 'Windows' does not exist in the namespace WpfApplicationTelerik' (are you missing an assembly reference?) ....WpfApplicationTelerik\Window1.xaml 6 26 WpfApplicationTelerik

What's wrong?

Null Reference exception

I've set up a MVVM approach to using the chart control. The first time a chart control displays it loads correctly and displays all of the data correctly. However, as soon as the the data context changes and a new view model is loaded, I get a null reference exception from the chart control. The stack trace does not contain any reference to my code. Below is the stack trace. Any ideas why this might be happening?

at Telerik.Windows.Controls.Charting.BaseAnimationConverter.GetAnimationSettings()
   at Telerik.Windows.Controls.Charting.BaseAnimationConverter.Convert(Object value, Type targetType, Object parameter, CultureInfo culture)
   at Telerik.Windows.Controls.Charting.StaticConverter`2.Convert(Object value, Object parameter, CultureInfo culture)

[Solved] Examples.CS

I'm a beginner to XBAP development.
The example that comes with Telerik WPF pack it's very cool, and I tryed to read it's source code to understand better how things work on it. But I miss something: I can't find how that left panel (that allow you to access every example) is created... The main wpf form is just a blank one, and I can't figure how Telerik guys did to make it work (how the secondary forms are loaded... I serched in the source but found nothing).

Anybody can help me?
Thank you all!
