This control has been working fine until today, but now it cannot be displayed for some reason.  This occurred after I added an empty WPF Custom Control Library project to the solution, which I have since removed...

The element "acbSelectPerson" could not be displayed because of a problem with Telerik.Controls.RadAutoCompleteBox:

InvalidCastException:

Is there a sample of using guage as aircraft horizon that supported roll and pitch values?

Thanks

I'm using the RadGridView with a dynamic object binding in order to show a grid of business objects (rows), each with properties (columns). The properties are not known before the business objects are selected.

Each property has its own viewmodel and related DataTemplate.

The GridCellPropertyContainerViewModel we are using for each grid cell encapsulates the relevant PropertyContent, so its DataTemplate uses a ContentControl, like so:

In my code-behind for the following XAML fragment, I would like to do "MyTextBox.Focus()", but MyTextBox is not accessible. Is there a way I can access it?

        <telerik:RadPropertyGrid Item="{Binding}"

Hey,

how can I adjust position of pasted element on diagram? Currently it's exactly in the same place as the copied element and it should be better to slightly move it to the right and down, so user will see the copy-paste action actually completed.

Any ideas?

Hi, i have massive problem.

If you only run the image editor, it works fine.

However, when i load an image editor from another program, i can not see the component values. Please check attached file.

Please i need your help. 

I look forward to your feedback.

Thanks

Few of our customers sometimes experience the exception above (I assume it doesn't always happen to them), and we get the crash report through our diagnostics system.

The stack trace is:

The problem looks like coming from:

RadRibbonWindow.SetThemeTemplate

Are you aware of issues that can cause it?

Thanks.

I've got a slider bound to a double property.  The double property controls the opacity of a shape right next to my control

When I drag the center thumb with the mouse, everything works perfectly.  The opacity changes in 0.01 increments, the tooltip updates and the opacity changes.  It does all of this smoothly.

When I try to drag that same thumb via touch, it just doesn't work.  It basically seems to go from 0 to 1.  Even if I set both small and large change to 0.01 and disable SnapToTicks (it has no effect). It won't drag smoothly.  I've even tried styling the thumb to make it use a very large size (just to be sure it's not me missing it with touch).  Still doesn't work.

What property do I have to set to make the slider change smoothly with touch as it does with the mouse?

I've attached an image of me dragging the center slider with the mouse where it's working perfectly.  

Here is my XAML

Hello

I use the RadScheduleView (Version 19.2.510) and have two questions regarding the appointment-editing window.

1) Can the window for the definition of the rule of an appointment repetition be called independently of the ScheduleView (for example, if you want to call the menu item "Edit rule" in a list of appointments)?

2) Is it possible to use your own window to edit an appointment, independent of the ScheduleView and with your own ViewModel?

Thanks
