hey! guys:
 I created a datatable by code and set it to gridView's itemsource, everything looks good ,I could grouping cols my drag it to group panel.
then I created a button, in button's behind code, I created some group descriptors and added them into grid's group descriptors, Oops,
the problem is coming , the grid is not grouped as I expected, some rows were missing. 
  After I deleted the group cols by closing the grouping button and drag cols into group panel, the group is ok again.
The codes is same as demo. Did I miss something ?

Dear Team ,
                  Is it possible in radtileviewitem to create custom template for minimize and maximize states.

Kind Regards 

Hi..

Do you have any Demo link for TreeListView Control in using WPF ?

Not quite sure how to detail this problem as it does not happen right away but only after the application has done some work, I'm still trying to isolate the issue but thought I'd post what I know.

Eventually the grid starts displaying a lot of wrong data especially when another window overlays the application and then is removed, the application window does not refresh until the mouse is moved over the screen. The odd part is that if you move the mouse down the screen is correct but when you move the mouse up the screen will display incorrect information.

In the simplest form the highlight line breaks up, but only when the mouse is moved up the screen. Its always correct when you move the mouse down the screen.

The attached image shows this condition where the current link and the highlight line are broken across multiple screen rows; again only when the mouse is moved up the screen, if its brought down over the rows they are then correctly refreshed.

Any clues on where I start looking for the problem.


After returning to the application it now displays the firefox screen in the body of the window as shows in the second attached png file. If you minimize the screen and restore it the display is correct but as soon as you move the window about the display it returns to the incorrect view - with the firefox window showing. Moving the mouse over the window causes it to be updated with the correct information. But the minimize/restore/move sequence again returns to junk.

I'm a newbie with WPF and I copied some code into my Resource Dictionary so that all standard TextBoxes and Buttons would get the radcontrols styles. I found it in another thread.

Now, I found that I can customize the error template using the following code.


How do I combine the two TextBox styles so that I can keep the Error Template at a common level (Control), and use it for all controls. Can I change the Error template style to be based on the Telerik ThemeResourceKey for Control? then base all other controls on it instead?

Hello,
I want simple full-text search on grid and with your api it seem to be very easy.


Problem arise when column type is not String. For Int or DateTime it raises exception.

1. Are you aware of this exception behaviour?
2. How to create FilterDescriptor not depend on column type, and how to search "formated value visible in grid" (not value in DTO)?

Hi,
I'm new to Telerik and have just downloaded the latest WPF trial.
I'm having trouble with the Gridview (version 2010.3.1110.35).
I'll post the XAML below, but I'm populating from an observableCollection pulled from a WCF service.
The grid populates OK, but I cannot group the columns please can you advise.
The window is binding to an ViewModel.

I've tried another sample wher I create some objects on the fly, putting them into an observableCollection and binding to it ... and
the grouping has worked fine.

Many thanks,
Joseph.

Hi,

I have a GridViewComboBoxColumn defined in my GridView in Xaml.  I have it set up to bind properly when I set the ItemsSource property on the GridView itself.  That works great.  I would like to know how to hide the combobox that is generated in specific rows when the Grid is bound based on certain criteria of the data items for each row.  How do I do this?

Thanks.
