DataGridTextColumn.IsReadOnly seems to be faulty


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')


Solution

  • Same as codekaizen but simpler:

    <DataGridTextColumn>
      <DataGridTextColumn.CellStyle>
        <Style>
          <Setter Property="UIElement.IsEnabled" Value="{Binding IsEditable}" />
        </Style>
      </DataGridTextColumn.CellStyle>
    </DataGridTextColumn>
