If I create a binding to the IsReadOnly property of the DataGridTextColumn, it does not actualize. If I set it through markup, it works.
<DataGridTextColumn IsReadOnly="{Binding IsReferenceInactive}"/> <!-- NOP -->
<DataGridTextColumn IsReadOnly="True"/> <!-- Works as expected, cell is r/o -->
The IsReferenceInactive property is a DP and works fine (For testing purposes I've bound it to a checkbox, that worked)
Is this a known limitation?
Update
Uups, other than I wrote, there is a message in the output window:
System.Windows.Data Error: 2 : Cannot find governing FrameworkElement or FrameworkContentElement for target element. BindingExpression:Path=IsReferenceInactive; DataItem=null; target element is 'DataGridTextColumn' (HashCode=23836176); target property is 'IsReadOnly' (type 'Boolean')
