XamComboEditor throws exception in VS Designer
posted

Since upgrading to v2014.1 VS studio designer will throw an exception "-Infinity is not a valid value for MinDropDownWidth" and will not render the xaml. However the application will build and run without showing this exception.

I believe the problem is in the EditorsGeneric or EditorsMetro.xaml "ComboEditor_EditableComboBoxTemplate" and "ComboEditor_NonEditableComboBoxTemplate"

if I change MinWidth="{Binding (igEditors:XamComboEditor.ComboEditor).MinDropDownWidthResolved, RelativeSource={RelativeSource TemplatedParent}}" to be a static value such as MinWidth="200", then the control will render in the designer.

So I think the MinDropDownWidthResolved should not return -infinity.

    Hello kcongdon,

    What version of Visual Studio are you using?  Also, what exactly do I need to do to reproduce this?  Can you give me some steps to follow?  Right now I added the EditorGeneric and EditorMetro.xaml files to my project along with the other dictionaries they require.  I got these from the Editors folder in the install directory. (C:\Program Files (x86)\Infragistics\2014.1\WPF\DefaultStyles\Editors)  I then added a XamComboEditor to the MainWindow and there is no designer error.  Is there more that I need to do?  I'm using Visual Studio 2012.
