XamDataPresenter v13.1 Theme Error on XamComboEditor
posted

I receive the following error at runtime when using the DataPresenter.  

System.Windows.Data Error: 4 : Cannot find source for binding with reference 'ElementName=BtnImage'. BindingExpression:Path=ActualHeight; DataItem=null; target element is 'XamComboEditor' (Name=''); target property is 'Height' (type 'Double')

I am attempting to use the Metro theme but since it seems I cannot set "Theme" on the XamComboEditor in XAML I am using the Metro styles (including all required styles).

The issue seems to stem from DataPresenter but shows up regardless of if I include the DataPresenter styles or not. I started including these styles to rid myself of this error. 

The error is not really impacting my application aside from throwing 3 binding errors which the user never sees. The error IS preventing me from performance profiling my application however.

Keep in mind that I get the error regardless of if the style files are included in my application. This is one of the source lines that apparently causes an issue:

From DataPresenterMetro.xaml in the FilterButtonStyleBase style:

<editors:XamComboEditor MinDropDownWidth="150" DropDownResizeMode="None" Opacity="0" ItemsSource="{Binding Operands, RelativeSource={RelativeSource TemplatedParent}}" SelectedItem="{Binding SelectedOperand, Mode=TwoWay, RelativeSource={RelativeSource TemplatedParent}}" IsDropDownOpen="{Binding IsChecked, Mode=TwoWay, RelativeSource={RelativeSource TemplatedParent}}" MaxWidth="1" Height="{Binding ActualHeight, ElementName=BtnImage}"/>

I am using the XamDataPresenter and I've specified a CardView. I am not allowing record filtering and I have no fields that would be edited with a combobox.
