我知道之前有人问过这件事.我正在检查是否有任何新的聪明解决方案.有没有更好的方法来绑定DataGridComboBoxColumn的Selectedindex？这是我在谷歌搜索后获得绑定工作的方式：
<!-- This is a little ridiculous --> <DataGridComboBoxColumn Header="Batch Type" ItemsSource="{Binding Source={StaticResource methodofPaymentItemsProvider}}"> <DataGridComboBoxColumn.ElementStyle> <Style targettype="ComboBox"> <Setter Property="Selectedindex" Value="{Binding MethodofPayment,UpdateSourceTrigger=PropertyChanged}" /> </Style> </DataGridComboBoxColumn.ElementStyle> <DataGridComboBoxColumn.EditingElementStyle> <Style targettype="ComboBox"> <Setter Property="Selectedindex" Value="{Binding MethodofPayment,UpdateSourceTrigger=PropertyChanged}" /> </Style> </DataGridComboBoxColumn.EditingElementStyle> </DataGridComboBoxColumn>@H_502_2@
解决方法
这是绑定DataGridComboBoxColumn的Selectedindex,ItemSource,IsReadOnly的最佳答案.
<DataGridComboBoxColumn Header="Batch Type" ItemsSource="{Binding Source={StaticResource methodofPaymentItemsProvider}}"> <DataGridComboBoxColumn.ElementStyle> <Style targettype="ComboBox"> <Setter Property="Selectedindex" Value="{Binding MethodofPayment,UpdateSourceTrigger=PropertyChanged}" /> <Setter Property="ItemsSource" Value="{Binding Streets,RelativeSource= {RelativeSource FindAncestor,AncestorType=UserControl},Mode=OneWay}"/> <Setter Property="IsReadOnly" Value="True"/> </Style> </DataGridComboBoxColumn.ElementStyle> <DataGridComboBoxColumn.EditingElementStyle> <Style targettype="ComboBox"> <Setter Property="Selectedindex" Value="{Binding MethodofPayment,RelativeSource={RelativeSource FindAncestor,Mode=OneWay}"/> </Style> </DataGridComboBoxColumn.EditingElementStyle> </DataGridComboBoxColumn>@H_502_2@ @H_502_2@
