Hi, i need to understand how to implement following thing. We are unable to navigate with Down key to Exit button in the backstage. I think this is a bug. I do not provide any source because it can be seen also in the example provided by your company (look at the attached picture). When user comes with keyboard to "Help" (look in the picture) he is unable to go down to buttons that are only "command" without anything to show on the right side of the backstage menu. This is a BUG. I should be possible to go there and in the area on the right should not be shown anything

Does anyone know how to Hide the Control Panel at the top of a RadGridView control? This is these are the controls that allow you to show and hide the different columns and such.

I'm trying to pass  a Telerik CrystalPalette to a Sub but I get an error "...is class type and can not be used as an expression".  Hints?

Public Function DoSomething() As Boolean
 
   ApplyThemeFontSizes(CrystalTheme)
 
End Function
 
Private Sub ApplyThemeFontSizes(Of T)()
 
        Try
 
            T.Palette.FontSizeXS = 8 + Me.FontOffset
            T.Palette.FontSizeS = 10 + Me.FontOffset
            T.Palette.FontSize = 12 + Me.FontOffset
            T.Palette.FontSizeL = 14 + Me.FontOffset
            T.Palette.FontSizeXL = 16 + Me.FontOffset
 
        Catch ex As Exception
 
            ' TODO: Log error to file (possible the Theme doesn't have a "Palette")
 
        End Try
 
    End Sub

Hello All,

      After hours of digging through the forums and help pages and examples, I have NOT found a complete example of how to bind a RadRichTextBox to a viewmodel property.  I would like to see a complete example , all the XAML and all the code in the viewmodel to setup the binding.  I think it should be fairly easy , all I want to do is display some simple text from my database (it's a property in the viewmodel) in a RadRichTextBox...  I'm sure I'll have to use a TxtFormatProvider for the control, but I can't seem to find a complete example of how to do this to bind to a viewmodel property.  The viewmodel property gets set on the viewmodels object instantiation .  I have looked at the Developer Focused Examples and found the data binding example , but that's not a View-View Model example.  

Thanks in advance,

Since you folks don't provide any Telerik Label or TextBox controls, we have to use the Microsoft default controls which I then find out will NOT be themed via StyleManager per this link.  

If using the XML approach, how are we supposed to use themes without key support for two of the most fundamental and basic controls like Label and TextBox?

It makes the entire purpose of "Application level" themes useless without this basic support.

Am I missing something?

Rob.

It seems when I set a theme globally (using Implicit) and new Window I show doesn't have the theme applied to the actual Window ... like Title bar color, font, windows background ... they all seem to inherit default and not my assigned theme (i.e. GreenTheme).  The telerik controls on the Window do indeed use my assigned theme.

Does Telerik UI WPF suite provide an alternative or is this a bug?

Cheers, Rob.

Hi,

I need to draw arrows on my ImageEditor.
These arrows must be drawn in multiple directions (N, NE, E, SE, S, SW, W, NW).
How can I accomplish that?

I implemented a Custom Shape tool and in my GetShapeGeometry() function I return the arrow Path figure.
But my shape seems to be crushed...

Any idea?

 

Thanks.

I linked the Search Command to the context menu in a gridview but the command is not executable. How can I enable the command?

See code:
        <telerik:RadGridView ItemsSource="{Binding Countries}" IsReadOnly="True" ClipboardCopyMode ="Default"
                             SelectionUnit="Mixed" SelectionMode="Extended"
                             >
            <telerik:RadContextMenu.ContextMenu>
                <telerik:RadContextMenu x:Name="ContextMenu32">
                    <telerik:RadMenuItem Header="Copy" Command="Copy"/>
                    <telerik:RadMenuItem Header="Open searchbar" Command="Search"/>
                </telerik:RadContextMenu>
            </telerik:RadContextMenu.ContextMenu>
        </telerik:RadGridView>

Thanks in advance for your help.
