RadMenuItem FlowDirection Changes Header Text

[James]

My project uses a RadMenu in the upper-right of the screen.  The menu needs to open from right to left so we use the flow direction "RightToLeft".  When using this flow direction, some header text with punctuation is rearranged.  Consider this example:

<telerik:RadMenu x:Name="radMenu2" ClickToOpen="False" Grid.Column="0" FlowDirection="RightToLeft">
  <telerik:RadMenuItem Name="testMenuItem" Header="Test">
     <telerik:RadMenuItem Header="123.ABC"/>
     <telerik:RadMenuItem Header="123ABC"/>
  </telerik:RadMenuItem>
</telerik:RadMenu>

In this case, when the menu is shown the first menu item will display "ABC.123" instead of "123.ABC".  The second item (without the period) displays fine.

  Other examples: 

•   "Test_" will display as "_Test"
•   "(Test" will display as "Test("
•   "100%Effort" will display as "Effort%100"

 
  For some reason, setting a flow direction of "RightToLeft" will rearrange any text that contains certain special characters.

  Is there a way to stop this reversal of the menuitem header text?

Hi James,

We have tested your scenario with our Menu and the regular one and they both behaved the same way. Unfortunately this is the default WPF behavior when using RightToLeft FlowDirection on the strings which contain number followed by a non-letter symbol and something else after that (their places are switched). Currently we are not aware of any work-around for this behavior.

If you have any other questions let us know.

Hi James,

Just a small addition - instead of using RightToLeft you could set HorizontalAlignment=Right. This will place RadMenu on the right of the screen. RadMenuItem has DropDownPlacement property which you can set to Left in order to open its popup from right to left.

Let us know if you need more information.
