Is it possible to group a Master-Detail Grid based on the columns in the Detail grid?

For example if you had nested grids of automobiles, the parent grid contained the make, model, color, year, etc... and the child grid contained the price, mileage, location (state or city), etc...

Is it possible to grab the header "location" and place it in the group panel of the parent so that Master-Detail Grid would be grouped by state?

This seems like something that should be available but I have not seen it implemented anywhere.

Thanks!

Merging Headers, or Hiding Header and leaving Group Headers?

I'm looking for a way to have a single column header display above 2 grid columns, but all of the posts I've been able to find from searching seem out of date. I tried styling the headers to hide the line in between (not a good solution anyway, since I need the text to straddle the two header cells), but couldn't figure out how to make it visually match the existing header cells. I don't need the filtering or sorting capabilities in this grid, so even being able to turn off the header while leaving the ColumnGroup headers on would accomplish what I need, but ShowColumnHeaders turns both off.

Is there a recommended approach to accomplish something like this?

Thanks,
Louis

Rounded Cell Corners

Hello, I was looking at this post http://www.telerik.com/community/forums/wpf/gridview/rounded-corners.aspx, and I was wondering if I could do the rounding at the cell level. I'm creating columns dynamically, so I don't know how to do a cell template. I was thinking of just adding a textbox with rounded corners as the cell template and remove the gridlines to get this effect, but adding columns dynamically prevents this I believe. I would like all cells in the grid to have the rounded corners.

Thanks,
Scott

Generate GridView from Dictionnary

Hello everybody,

I need to generate a GridView at runtime from a Dictionary<DateTime,Dictionary<string,double>>.

I would like to display the different DateTime keys in GridView columns. The rows header of the grid would be fill with string keys of the second dictionary and the cells with values of this dictionary.
I precise that the keys of the Dictionary<string,double> are the same whatever the DateTime you choose.
I would like to know if it is possible to do such a thing only using xaml and binding or if it is necessary to build the grid in the xaml.cs file or if I need to use another method.

There is an example of the expected result :

	Date1	Date2	Date3	Date4	…	Date m
String1	0	1	1,8	2,8	…	12,9
String2	0,5	16	15	5	…	2,9
String3	2	8	18	6	…	1,9
String4	4	7	12	1	…	1
…	…	…	…	…	…	…
String n	0	6	17	24	…	13

Thank you for your help.

Regards,
Thomas

Threading issue with RadDocking

The company for which I'm consulting has a specific business requirement that each instance of
certain WPF Windows MUST have their own UI Thread and NOT share the default UI thread created
by .NET Framework when the application is first loaded. From a coding perspective, this is easy to
accomplish and works well, until introducing the Telerik RadDocking control in the WPF Xaml. I have
copied and pasted the xaml form telerik's RadDocking example directly from the sample code without
modifying it. When the app launches, both instances of WindowWithTelerikDockingFromExample
[seemingly] load without issue at first, in fact, the second instance of the window (titled "Window on
seperate UI Thread...") is operational and works, as does "MainWindow". It's not until you activate
the second window and then activate the main window, and then switch back to the second window
that the following exception is thrown:

"The calling thread cannot access this object because a different thread owns it."

Floating Pane Boundary

Hey guys,

I was wondering if there was anyway to force a floating-only pane to stay inside a certain boundary. For example, lets say I have a RadPane that takes up the top half of the screen. I would like the smaller floating pane to be restricted to stay inside that RadPane's border, so the user cannot 'float' the pane to the bottom half of the screen.

Is this possible?

Thanks,
Niko

DataFormDataField Label + Control widths

Is there any (easy) way to create a fixed width label with a variable width edit control (anchored at left, expands to fill available space to the right)? I am not AutoGenerating the fields, but I would prefer to use the telerik:DataFormDataField control for the sake of simplicity, rather than butcher together my own mess using a StackPanel or something similar.

I have a number of resizable forms, and the default way that labels and controls resize themselves doesn't really work that well.

Thanks,

Dan.

Validation message aren't displayed for RadNumericUpDown

Hello,

I'm currently working on a WPF application which has a few RadNumericUpDown controls and RadMaskedNumericInput controls.

We are working with data annotations to perform validation (including custom validation)

Now i've noticed that for RadMaskedNumericInput controls, it will display the validation message next to the control and change the border color to red.
However, for RadNumericUpDown controls it only changes the border to red but doesn't display the message.

Is this standard behaviour or am I missing something?

Kind regards,

NumericUpDown
