Infragistics XamDataGrid AllowEdit property binding not working

Question

In my XAML I'm trying to bind AllowEdit of my XamDataGrid to a property

<igDP:XamDataGrid.FieldSettings>
  <igDP:FieldSettings AllowEdit="{Binding Path=DataItem.Approved}"/>
</igDP:XamDataGrid.FieldSettings>

But it doesn't work. All other bindings work fine. Any ideas? I'm new to WPF so any help would be appreciated

Answer 1

Perhaps you're binding to ObservableCollection? If that's the case, you can't edit your items. You can try bind to BindingList instead.

Answer 2

Apparently you (still.....) cannot bind this property: http://www.infragistics.com/community/forums/t/10907.aspx sigh...

Answer 3

I use a style to get around this limitation, e.g.:

<igWPF:Field Name="SomeValue">
    <igWPF:Field.Settings>
    <igWPF:FieldSettings EditorType="{x:Type igWPF:XamNumericEditor}">
        <igWPF:FieldSettings.EditorStyle>
        <Style TargetType="{x:Type igWPF:XamNumericEditor}">
            <Setter Property="IsReadOnly" Value="{Binding DataItem.IsReadOnly}" />
        </Style>
        </igWPF:FieldSettings.EditorStyle>
    </igWPF:FieldSettings>
    </igWPF:Field.Settings>
</igWPF:Field>

I usually used a style to achieve this as in @larsmona's answer above. Recently I learned about using CellBindings and FieldBindings to achieve this.
