How to bind DataGridColumn.Visibility?

I need to have a Column within a Silverlight DataGrid be vis

Answer 1

From your MyDataGridTextColumn class, you could get the surrounding DataGrid. Then you get your ViewModel out of the DataContext of the DataGrid and add a handler to the PropertyChanged event of your ViewModel. In the handler you just check for the property name and its value and change the Visibility of the Column accordingly. Its not quite the best solution, but it should work ;)
