Infragistics的XamDataGrid AllowEdit屬性綁定不工作

Question

在我的XAML我想AllowEdit我XamDataGrid的綁定屬性

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

但它不工作。所有其他綁定工作正常。有任何想法嗎？我是新來的WPF所以任何幫助，將不勝感激

Answer 1

也許你有約束力ObservableCollection？如果是這種情況，則無法編輯您的項目。您可以嘗試綁定到BindingList。

Answer 2

顯然，你（仍然.....）不能將此屬性綁定：http://www.infragistics.com/community/forums/t/10907.aspx 嘆息......

Answer 3

我使用樣式來繞過這個限制，如：

<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>

我通常在@ larsmona的回答中使用了一種風格來實現這一點。最近我學會了使用CellBindings和FieldBindings來實現這一點。
