How to add Custom Commands to TreeView Context Menu

[Nour Douffir]

Hello,

I am trying to add a custom command to add a node to the treeview, but it's not binding. I set the data context to the view model that contains AddNodeCommand, but I keep getting a binding failure.

<sync:SfTreeView.ItemContextMenu>
                <ContextMenu>
                    <MenuItem Command="{Binding AddNodeCommand}" Header="Add Node"/>
                </ContextMenu>
</sync:SfTreeView.ItemContextMenu>

Any assistance with this would be much appreciated.

Hi Nour, 

You can make the command to work properly by binding as shown below.  

<sync:SfTreeView.ItemContextMenu>
                <ContextMenu>
                    <MenuItem Command="{Binding Path=TreeView.DataContext.AddNodeCommand}" Header="Add Node"/>
                </ContextMenu>
</sync:SfTreeView.ItemContextMenu>
