Question

我添加了这个控件如何动态地为它分配标签和内容？

<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>

Answer 2

serversList.Items。??

例如，您可以将文本框添加为您的combox项目

TextBlock tx = new TextBlock();
tx.Text = "something";
cbTst.Items.Add(tx);"

或者你可以删除这样的项目： cbTst.Items.RemoveAt（要删除的项目的索引）
