Designer error with HierarchicalData
posted

I have a bogus error in the designer, apparently, when using the xamGrid 14.1.

"A column has been added with an Empty key.  All columns must have a unique key."

The same thing happens in the sample browser: IGGrid.Samples.Data.HierarchicalData


The error appears on the first column in the first child band/relationship.  That column has a key.

Any advice?  Its not a biggie since the code compiles and runs correctly.  Its not annoying enough that I'd move the junk to the code behind.  I'm a bit of a WPF novice.  Are there error suppression options to tell the WPF designer not to complain about certain issues?

Thanks, David
