獲取Datagrid（WPF）中ComboBoxColumn的選定值

Question

我使用XAML在Datagrid中實現了DataGridComboBoxColumn。 我可以以編程方式訪問comboboxColumn1，但是如何在值更改時獲取所選項目？

 <DataGrid x:Name="dgData" AutoGenerateColumns="False" Margin="131,93,13,101" Grid.Column="1" SelectionChanged="dgData_SelectionChanged">
       <DataGrid.Columns>

            <DataGridComboBoxColumn Header="Subject" x:Name="comboboxColumn1"/>

       </DataGrid.Columns>
 </DataGrid>

Answer 1

試試這個

<DataGridComboBoxColumn Header="Life Area" SelectedItemBinding="{Binding YourSelectedItem}">
    <DataGridComboBoxColumn.ElementStyle>
        <Style TargetType="ComboBox">
            <Setter Property="ItemsSource" Value="{Binding YourItemSource}"/>
            <Setter Property="IsReadOnly" Value="True"/>
        </Style>
    </DataGridComboBoxColumn.ElementStyle>
    <DataGridComboBoxColumn.EditingElementStyle>
        <Style TargetType="ComboBox">
            <Setter Property="ItemsSource" Value="{Binding YourItemSource}"/>
        </Style>
    </DataGridComboBoxColumn.EditingElementStyle>
</DataGridComboBoxColumn>
