I have a collection, something like this
Data Source (custom object)
This is a List<MyCustomObject> that contains all the properties.
Properties (strings):
Upon binding to the grid, i need to flip this. I need each unique ID to become a new column, the value to be the data of that column, and the descriptoins to represent rows.
Example of final outcome:
ID ID {Infinite across}
DESCRIPTION VALUE VALUE
DESCRIPTION VALUE VALUE
DESCRIPTION VALUE VALUE
{infinite down}
How do you recommend i accomplish this?

How long before we have a new Roadmap? I'm currently evaluating different WPF components and need to know the future direction before I make a final decision.

I borrowed the code from the C# Examples and modified it to show the issue as well as another problem I've addressed in a separate posting. Notice that changing the resource dictionary that is merged using the buttons at the top does not effect the display of the gridview as expected. The other elements on the page do change, and if the alternate dictionary is loaded at the start it changes, but the buttons do not effect the grid. What gives?

I have a RadGridView that is bound to a list of Medication Objects.
A medication contains the following fields:
Drug - object Bound to Drug.Name
Dosage - string Bound to Dosage
StartTime - DateTime Bound to StartTime
EndTime - DateTime Bound to EndTIme
Comments - String Bound to Comments
When the control binds to my list, all of the fields are allowed to be grouped except for the Drug.Name. Is there a way to group this column?
Here is my XAML

We have a WPF project which uses several telerik grids. We bind to the grids by using setting the DataContext property in the Window_Loaded, and the ItemsSource on each grid to "{Binding}". Using the Q308 release, the grids worked in Blend and Visual Studio (though had a whole host of other issues which I won't get into). Now that Q109 is out, I have upgrade all of our references to the new DLLs, but not changed any code. The project will build just fine, and the application will work (other than an issue that I will submit in another post).
However, with the new DLLS, the Visual Studio designer will crash as soon as I open the XAML (with no error), and Expression Blend refuses to open the XAML - it displays a NullReferenceException, which appears to being thrown in the Telerik.Windows.Controls.GridView.GridViewITemsControl.DisconnectFromDataEventsFunction(). I would paste the entire contents of the exception, but the developers of Blend apparently saw fit to not include the ability to copy the text of errors that occur in the application.
Any ideas, or do you need more information?

Hello,
I have a collection of a class implementing ICustomTypeDescriptor bound to WPF GridView. Basic functionalities such as viewing, sorting, grouping and filtering works fine. But when I try to add an AggregateFunction to the groups I receive a null reference exception. As far as I can see, the Properties collection of the RecordManager for the grid does not contain the property descriptions from the ICustomTypeDescriptor, Is there a solution or workaround for this situation?
Additionally, I would expect TypeDescriptionProvider attribute on a class would perform similar as implementing ICustomTypeDescriptor interface for the class. The Microsfot ListView control, for example, can handle this situation.
Thanks,
Mehmet Ali

Hi,
just loaded up the eval WPF Controls. I browsed through the demos and the only problem I found was with database access configuration (but I'm not too worried about that). What I did notice was the demo itself! On my install the documentation reports as being corrupt (after install, uninstall and install) so I'm unable to look in there, but do you publish details of the application itself? Particularly the Navigation panel on the left :-) The source seems to be only partly supplied with the remainder being in Telerik.Windows.Quickstart.dll.
How is the Navigation panel put together? How does it slide the demo's in and out?
thanks

Can you guys give me an example of selecting a row in the grid using databinding?
My DataContext will have a custom object with two values:
My DataContext will have a custom object with two values:
- Object ItemsSource
- Int SelectedRow
I want to use updates to the DataContexts to auto update the grid, ItemsSource="{Binding Path=ItemsSource}" works for the data, but i cannot figure out the selected row.
