Hello,

I have a strange issue with the datacontext-binding to the application-menu, which I do not have when binding to the ribbon-tabs

I have my Viewmodel which exposes iCommands.

First, whta is working correctly:

When I bind to a ribbonTabItem, the following works OK

<

igRibbon:RibbonTabItem x:Name="xamRibbon1_Tab_Main" Header="Main" DataContext="{Binding Path=Ribbon_ApplicationMenu_ViewModel}">

<igRibbon:RibbonGroup Id="ribgrp_Main_MainData" Caption="Main Data">

<igRibbon:ButtonTool Id="rib_Main_Data_ProjectNew" Caption="New Project" Command="{Binding Path=Project_New_Command}"</igRibbon:ButtonTool

</igRibbon:RibbonGroup>

</igRibbon:RibbonTabItem>

When I bind to the same to the applicationMenu --> my commands don't work when clicked on button

<igRibbon:XamRibbon.ApplicationMenu>

<igRibbon:ButtonTool Id="rib_App_Menu_ProjectNew" Caption="New Project" Command="{Binding Path=Project_New_Command}"</igRibbon:ButtonTool>

</

igRibbon:ApplicationMenu>

</igRibbon:XamRibbon.ApplicationMenu>

In my output-debug window I wrote system.out-lines when the "get of the Command" in my viewModel is executed.

Now the strange part: in both cases, the debug-line is printed out (so the correct command should be linked...)

But when clicking on it in the application-menu, nothing happens. but when clicking on it in the ribbontabitem, my command is executed.

I did the test also with simple databinding with a string to the caption --> both thimes the getter for the text is executed, but in the application-menu the caption is EMPTY !!!

Does anyone have an idea what could be wrong?

*) is setting the datacontext for applicationmenu working: I think yes, because the getters on my viemwodel are executed

But why do they not react to a click, why is the caption EMPTY in app-menu and not in ribbontab...

My goal is having different Viewmodels for the application-menu, eacht tabitem, ... instead of one big Viewmodel for the whole ribbon.

But if that's the solution, only 1 datacontext binding to the whole ribbon, then I can maybe change my idea.

thx

Fred
