c# - 在 Windows 应用商店应用程序中动态填充组合框

Question

我添加了这个控件，我是如何动态分配它的标签和内容的？？

<ComboBox x:Name="cbTst" SelectedValue="{Binding SelectedDirection, Mode=TwoWay}" SelectedValuePath="Tag" Canvas.Left="82" Canvas.Top="19">
  <ComboBoxItem Content="North" Tag="0"/>
  <ComboBoxItem Content="East" Tag="90"/>
  <ComboBoxItem Content="South" Tag="180"/>
  <ComboBoxItem Content="West" Tag="270"/>
</ComboBox>

Answer 1

        ComboBox cbTst = new ComboBox { Height = 30, Width = 100 };
        cbTst.SelectedValue = "{Binding SelectedDirection, Mode=TwoWay}";
        cbTst.SelectedValuePath = "Tag";

        cbTst.Items.Add(new ComboBoxItem { Content = "North", Tag = 0 });
        cbTst.Items.Add(new ComboBoxItem { Content = "East", Tag = 90 });
        cbTst.Items.Add(new ComboBoxItem { Content = "South", Tag = 180 });
        cbTst.Items.Add(new ComboBoxItem { Content = "West", Tag = 270 });

        Gridx.Children.Add(cbTst);

XAML:

   <Grid x:Name="Gridx" Margin="231,162,201,147">
   </Grid>
