[Solved] Available Decimal Places in Double Editor

Hello,

It seems that the stock editor that the Data Filter provides for double values allows only 2 decimal places. Is there any way to change this, or do I need to implement a custom editor?

Thanks,
Mark.

Event Properties Cause Designer Exception of MS.Internal.Validate+ValidationFailure

Edit: My apologies, it appears this is a known issue and is being worked on.
http://www.telerik.com/support/pits.aspx#/public/wpf/5166

Hello,

I'm having a bizarre issue with the RadTabControl related to the design interface in Visual Studio 2010. Every time I try to edit or view the events of the RadTabControl, it crashes the design interface forcing me to reload. I am getting an exception of MS.Internal.Validate+ValidationFailure each time it fails. Whenever I can actually click on the "Events" tab in the properties window, it continues to show the properties. This seems to be related to the Q1 2011 release as I was not having this issue before. Reinstalling the Q1 release did not fix the issue.

The application compiles and debugs without any problems even with the event still defined, so the problem seems purely on the VS side. Any idea what could be causing this?

Thanks,

Kyle

Using keyboad shortcut and arrow keys problem

I have a menu with vertical orientation, when I use mouse to navigate in the menu I have no problem. But if I open a menu that has a submenu (Accounting in this example) with a short cut key (Alt+A) I have difficulties when using Down Arrow key to navigate to the next menu item inside the submenu popup.
This is not an accepted behaviour. I have noticed that if I leave my mouse pointer in the place that the submenu popup opens and open the menu with a shortcut key there won't be any problem using Down Arrow key to move down inside the popup.

Grid became crashable in the edit mode

Hello there,

I found that the WPF grid is easy to crashed while in the edit mode. Take an example as the attached screenshot.
I have 2 grid. The one on the top is the master and the one below is the detail table based on the selection of the row in the master table.
What I found that if I was editing the detail table but didn't commit. While the detail table is still in the edit mode, if I accidently select another row in the master table, it will cause the crash/frozen of the Grid control.

I have the screenshot upload usign the general ticket system.

Error 12 The type reference cannot find a public type named 'RadDataPager'

Hello,

Im having an issue with the RadDataPager and the RadTabControl:

When adding this section to our ResourceDictionary, I get a compile error "Error 12 The type reference cannot find a public type named 'RadDataPager'":

   <Style TargetType="{x:Type telerik:RadDataPager}">
   <Setter Property="telerik:StyleManager.Theme" Value="Office_Blue"/>
   </Style>

The same goes for the RadTabControl.

This error does not occur for the rest of the telerik controls within the dictionary, which set the theme for the RadButton, RadGridView, RadExpander etc.

Kind regards,
Mike

Video tearing/Flickering in WPF

I am using a TCP/IP protocol to connect to the Device(Video) and render the Video onto WPF application. The frame rate from the device is around 3 - 4 Frames/Second . I also understand that the lower frame rate could also be the possible reason for flicker but when i run my C++ application and try to render the video its flicker free (even though there is some latency).

Please suggest on this ....
