把這個場景,我與像控制網格工作:綁定依賴屬性到另一個依賴屬性
<RadGrid DataContext={Binding someDataContextObject, Mode=OneWay}>
<RadGrid.columns>
<RadGrid.Column Header="Column Header"
DataMember="{Binding dataContextObjectProperty, Mode=OneWay}">
[...]
<DataTemplate>
<MyCustomControl Data="{Binding ???}" />
</DataTemplate>
<\RadGrid.Column>
</RadGrid.columns>
</RadGrid>
我想MyCustomControl的數據依賴屬性綁定到列的數據成員依賴屬性以避免多個綁定到相同的數據。我該怎麼做?
