I am developing an add-in for Revit 2016 and right now I am using a WPF window to display results in a DataGrid (however the issue I am about to describe also happened while using WinForms)
I am trying to format and setup my DataGridView at Design Time but I cannot bind to the main class which implements the API interface IExternalCommand.
<Transaction(TransactionMode.Manual)>
Public Class MyClass
Implements Autodesk.Revit.UI.IExternalCommand
....
End Class
When I try to set the Window datacontext at design time:
<Window x:Class="MainWindow"
....
xmlns:dvm="clr-namespace:MyAssembly"
d:DataContext="{d:DesignInstance {x:Type dvm:MyClass}}"
....
>I get the following error:
The name "MyClass" does not exist in the namespace "clr-namespace:MyAssemnbly".
Other than this the add-in compiles and works fine, but I would really need be able to use the Designer to ease the development.
What I tried so far (with no success):
- Changing Target Framework from 4 to 4.7 and in between (went back to 4.5)
- Changing target CPU from Any to x64
The workaround for now was to create a dummy class and duplicate the properties from the main class.
Can this be done? What am I doing wrong?
note: when working with WinForms the similar issue was that when defining an Object based DataSource, MyClass would not show up in the list. If I removed the Transaction and Interface implementation (basically making it independent from Revit API assemblies) it did show up.
Thank you in advance to anyone who can help me!
