I am having a problem with XamContextMenu. I've just started to look at it but at the moment I cannot get it to work at all.
I am using the most basic example straight from the documentation:
<TextBox Height="23" HorizontalAlignment="Left" Margin="68,30,0,0" Name="textBox1" VerticalAlignment="Top" Width="120">
<ig:ContextMenuService.Manager>
<!--If you use the Infragistics Commanding Framework, you should set the OpenMode property to None-->
<ig:ContextMenuManager ModifierKeys="Shift" OpenMode="RightClick">
<ig:ContextMenuManager.ContextMenu>
<ig:XamContextMenu Name="contextMenu2">
<ig:XamMenuItem Header="Font" />
<ig:XamMenuItem Header="Formatting" />
</ig:XamContextMenu>
</ig:ContextMenuManager.ContextMenu>
</ig:ContextMenuManager>
</ig:ContextMenuService.Manager>
</TextBox>
When I run this and try to invoke the context menu (Shift + Right mouse click), I get a run-time exception:
Unable to cast object of type 'Infragistics.Controls.Menus.XamContextMenu' to type 'Infragistics.Controls.Menus.XamMenu'.
I am using InfragisticsWPF4.v10.3 library. I have tried it for different controls - no luck, the same exception.
What is wrong here?
Hi,
I tried to reproduce your issue but without success. Could you please let me know the build number you are using - it can be seen as the 'Version' property of any of our assemblies, e.g. 10.3.20103.2065?
Could you provide any other additional information, maybe something about your page and other controls on it, etc. Ideally, you could send me a separate project sample where the issue is reproducible.
Thanks,
Thanks Stoimen. I am using 10.3.20103.1003.
Sorry, your other questions: it is a very simple app - I just created it from scratch to get the context menu working at all. Just one window and the text box I posted above. Nothing else there.
Did you try applying any recent Service Release ?
As I stated above, this looks like an issue we had in 10.3 RTM build. Applying the latest Service Release should fix the problem.
Regards,
I am getting the same issue. I use 2010 v3.

Thanks Stoimen and Georgi. I will try that.
The answer georgi provided above should solve your issue - basically you just need to update to the latest Service Release to have that issue solved.
HTH,
