Retrieving SelectedValue from RadCombobox

Hello!

I'm using the RadCombobox for WPF in a winform. I am able to dynamically create the control populating it from a datasource and setting some other properties then adding the control as a .Child to an ElementHost control. My problem is that I don't seem to be able to reference the selected value of the combobox through the ElementHost control. I am also adding an "AddHandler" to this code but don't seem to have the right event to capture the change of selection. The event at this point that seems to work is the DropDownClosed. I'm using vb for code behind. Any code examples or suggestions would be greatly appreciated!

Thanks much!

IsDropDownOpen problem

Hi

I have problems keeping the dropdown open in RadComboBox. My combo is editable, the textsearch is disabled. In the GotFocus event i set IsDropDownOpen to true, but it closes immediately. Also after that i can't open it by clicking on the dropdown button.
I noticed that the regular WPF combo has a StaysOpenOnEdit property, which i couldn't find in RadComboBox. (with the regular combo i got this working, but i'd like to use RadComboBox.)

How to change the node selection style.

How would I go about changing the node selection style of the RadTreeView. I don't like the default color and how it selects the full row.

Thanks

Code

object currentRec = gvMainWorkQueue.SelectedItem;

gvMainWorkQueue.ItemsSource = GetDataSource();

gvMainWorkQueue.Rebind();

if (currentRec != null) {

gvMainWorkQueue.SelectedItem = currentRec;

gvMainWorkQueue.BringDataItemIntoView(gvMainWorkQueue.SelectedItem);

}

Also not having any luck with 2009 Q2.

Binding Collection of Collections to GridView

Anyone,

First, I must say I am new to Telerik controls, so please forgive my ignorance.

My issue: I have a collection of objects which have multiple collections of objects which have objects.

Workflows
-- containing details
-- -- containing specific action
-- containing schedule
-- -- containing recurrence data

I am able to successfully bind the workflows.

I am able to use a variety of methods to bind the next level, details or schedule.

I have not been successful binding the third level of the hierarchy. I have tried the "property" method and the "field descriptor name pair" method.

I would welcome any help,

GridView

We are evaluating Telerik control for our next gen Rich client app development, and downloaded trial version of Telerik WPF Toolkit. However, after installation, i don't see the tileview control in control tool box ? Is it missing or is it available only in silverlight world ?

Cheers

AutoGenerateColumns Ignored under certain conditions

I have the latest build of WPF Q2 SP1 and I am getting the following error:
A TwoWay or OneWayToSource binding cannot work on the read-only property 'xxx' of type 'TelerikTestProject.TestClass'. This error happens whenever I place the GridView inside of a Actipro PopupButton and then inside of a Actipro ResizableContentControl. If I take the RadGrid out of the control I don't get the error. I have a sample project I can send you to reproduce the error.
