Are there plans to allow a user to pick a custom color, not just one from the palette?  Without this, the color picker is useful, but much less useful for general purpose use.

I try to use the function ExportToImage(Stream) from a RadChart object and it always throw an null reference exception whatever the chart I try. 

Here is a sample code I try to test the function :



Exception throw at this line :

chartTest.ExportToImage(ms);

Exception message :

{"Object reference not set to an instance of an object."}

Exception call stack :

Hello,

I am looking for general advice/guidance on using the RadDataFilter when the filtered result is displayed in a Grid that uses Value Converters.  Let me paint the scenario...

In the general use case, the RadDataFilter accepts a Source and emits a FilteredItemSource.  The Source is the collection of items to be filtered, and the Filtered ItemSource is the result of the filter, that can be bound to some other control like the RadGridView.  However, if a column in the GridView used to display the results uses a Value Converter to modify the displayed value in any way, you can get into a problem that will cause a lot of confusion to the user.  Namely, the filter no longer operates on values as displayed in the grid.  So when the user enters filter criteria, the grid may not filter as expected because the user is most likely entering values that match the display in the grid, while the filter is operating on the underlying values. 

I believe that this problem can also be demonstrated when perhaps the backing data contains a value of type double, while the datagrid uses a string format to show the value as a percent.

Although I believe I know why things are working this way, I am wondering what the best-practices might be to get things to work as expected from the user.  Should we refrain from using Value Converters in the display, and instead do the conversion in the backing store (i.e. the RadDataFilter's Source collection) hence operating on raw values only?  If so, this seems a little unfortunate.  Is there another approach that might be helpful here?

I am curious to hear whether anyone else has run into this problem and what you might have done.

Thanks,
Mark.

Hello,
I have upgraded RadControls version to RadControls for WPF-2010.3 1314 (Jan 14, 2011) in my WPF form and now the Texts in the Gridview header and rows are not wrapping properly. Please help to find out any property that can be used in design or code for the wrapping the text.

I found that the properties "TextAlignment" and "TextWrapping" is obselete in new Telerik version.

GridView.AlignmentContentPresenter is also obselete.


Thanks,
Sooraj
