在ComboBox中的DataGrid中显示所选项

时间：2021-11-15 23:00:47

I have a WPF toolkit DataGrid as the dropdown in a ComboBox template.

我有一个WPF工具包DataGrid作为ComboBox模板中的下拉列表。

<toolkit:DataGrid x:Name="InnerGrid"
                  ItemsSource="{TemplateBinding ItemsSource}" 
                  CanUserReorderColumns="False" CanUserResizeColumns="True" 
                  CanUserSortColumns="False" CanUserResizeRows="False" 
                  AutoGenerateColumns="False" CanUserAddRows="False" CanUserDeleteRows="False">
    <toolkit:DataGrid.Columns>
        <toolkit:DataGridTextColumn Header="Account" Binding="{Binding Name}" IsReadOnly="True" />
        <toolkit:DataGridTextColumn Header="Description" Binding="{Binding Description}" IsReadOnly="True" />
    </toolkit:DataGrid.Columns>
</toolkit:DataGrid>

When I select a value using the DataGrid in the dropdown, the selected item shows as highlighted in the DataGrid. When I set the selected value of the ComboBox programmatically or by using the arrow keys when the dropdown is closed, the selected item won't highlight in the DataGrid.

当我在下拉列表中使用DataGrid选择值时,所选项目在DataGrid中显示为突出显示。当我以编程方式设置选定的ComboBox值或在关闭下拉列表时使用箭头键时,所选项目将不会在DataGrid中突出显示。

Is there some kind of binding I need to do within the DataGrid to highlight the selected item?

我是否需要在DataGrid中进行某种绑定以突出显示所选项?

As Chris Nicol mentioned, I did just need to add a binding to the SelectedItem of the ComboBox, in this case the TemplateBinding.

正如Chris Nicol所提到的,我只需要添加一个绑定到ComboBox的SelectedItem,在本例中是TemplateBinding。

<toolkit:DataGrid x:Name="InnerGrid"
                  ItemsSource="{TemplateBinding ItemsSource}" 
                  SelectedItem="{TemplateBinding SelectedItem}"
                  CanUserReorderColumns="False" CanUserResizeColumns="True" 
                  CanUserSortColumns="False" CanUserResizeRows="False" 
                  AutoGenerateColumns="False" CanUserAddRows="False"
                  CanUserDeleteRows="False">
<snip>

Sounds like you need to bind the selectedItem of the ComboBox to the SelectedItem of the DataGrid. Can you update the question to include the comboBox?

听起来你需要将ComboBox的selectedItem绑定到DataGrid的SelectedItem。你能更新问题以包含comboBox吗?
