How to get the result preview from the editor

Hi,

I create a RadExpressionEditor and assign an object base on the following class.

class TestClass
{
public string Name { get; set; }
}
Using the editor, I enter the following expression (Count(Name)). At the bottom of the editor, there is a label "Result Preview" that show me the result of the expression.

So, I add a button in my interface to retrieve this value, but I don't see a way to get the result of my expression.

So, what is the best way to retrieve the result of my expression base on a specific object?

Best Regards,

ExpressionEditor

Themes - missing files ?

I have WPF 1Q 2012 SP1 and I am trying to follow the info on this page:
http://www.telerik.com/help/wpf/styling-apperance-themes-runtime.html

the instructions seem to be referring to some dll files that I can not find or do not have.

like this:
Add the required assemblies from the Binaries.NoXaml folder located in the RadControls installation folder. Include also the theme assemblies:

it then shows a screen shot that seems to list some dll files named like this Telerik.WIndows.Themes.* and I do not have them.

later in the help it also tells me to add to the app
Add the needed resource dictionaries for the default theme in App.xaml:
and refers to
Source="/Telerik.Windows.Themes.Office_Black;component/Themes/System.Windows.xaml"/
which reads as a packed URI in a dll also....

but I do not have the dlls ???
do I have to copy the xaml files and make my own dll's to use this or what ??
did some prior release have the files and the version I have assumes I have the prior release installed to provide the missing files ?

Only able to set Date by the picker

I want the user to only be able to set the data by clicking on the calander itself and the textbox that displays the text to be readonly.

If I set the control to IsReadOnly then the whole onctrol does not set the data so that will not work. I also could not find a property with wich I can set this behavior.

QueryableDataServiceCollectionView Distinct not Supported

I have a QueryableDataServiceCollectionView bound to a RadGridView and RadDataPager. Working good so far. Except, when I try to pop down the filtering menu, I get a Distinct is not supported error from WCF Data Services. Which makes a lot of sense. WCF Data Services doesn't support Distinct.

So why are you guys trying to use Distinct? The control should be smart enough to know that it's not supported, and do it some other way...

Problems with Impersonation and GridView

I have been having some issues trying to use an impersonated application with telerik controls in it, especially the RadGridView.

It shows a access denied in one of the resources for the grid.

I have linked to a sample project where you can test it. It requires that someone with no access to the current PC login through the application.

It uses windows authentication for the credentials.

Here is the sample code

Hi,

Below error is seen after upgrading to latest Telerik Release 2012.3.1207.40
