WPF and RibbonControlsLibrary throws a BindingExpression path error without even using Bindings?
c#, data-binding, ribboncontrolslibrary, wpf, xaml
Solution
I see that error in the VS output for any ribbontogglebutton. I have attempted to resolve it, but with no luck. Unfortunately, the only fix I have come up with is that it's one of those errors you can ignore.
Problem
I have a question regarding WPF and RibbonControlsLibrary. I tried to find the source of this error myself but I just do not seem to be able to find it. I am using the WPF RibbonControlsLibrary from Microsoft. When using the RibbonToggleButton I get the following error even without any bindings in my XAML code. ``` <r:RibbonWindow x:Class="WpfApplication.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="300" Width="300" xmlns:r="clr-namespace:Microsoft.Windows.Controls.Ribbon;assembly=RibbonControlsLibrary"> <r:Ribbon> <r:RibbonTab Header="Admin" > <r:RibbonMenuButton/> </r:RibbonTab> </r:Ribbon> </r:RibbonWindow> ``` System.Windows.Data Error: 39 : BindingExpression path error: 'IsChecked' property not found on 'object' ''RibbonMenuButton' (Name='')'. BindingExpression:Path=IsChecked; DataItem='RibbonMenuButton' (Name=''); target element is 'RibbonToggleButton' (Name='PART_ToggleButton'); target property is 'NoTarget' (type 'Object') I am a bit confused by the last part of the error: `target element is RibbonToggleButton (Name='PART_ToggleButton'); target property is 'NoTarget' (type 'Object').` There is no RibbonToggleButton in my XAML code at all? Did someone else see such a behavior and is able to point me into the right direction to get rid of this error output?
