问题动态创建组合框 [英] Issue in creating combobox dynamically

问题描述

我试图动态创建一个组合框，但无法创建它。
下面是我写的代码

 组合框com_dynamic =新的ComboBox（）。 
 com_dynamic.Height = 50; 
 com_dynamic.Width = 100; 
 LayoutRoot.Children.Add（com_dynamic）; 
 tb.Margin =新厚度（0，145，87，0）; 
 tb.VerticalAlignment = VerticalAlignment.Top; 
 tb.Horizo​​ntalAlignment = Horizo​​ntalAlignment.Right; 
 
 ComboBoxItem com_dynamic_item =新ComboBoxItem（）; 
 com_dynamic.AddChild（com_dynamic_item）; 
 com_dynamic_item.Content =ITEM1; 
  

解决方案

您也应该组合框添加到一个容器控件。如果你想将其添加在 LayoutRoot ，那么这就是你缺少的行。

  LayoutRoot.Children.Add（com_dynamic）; 
  

您可以使用它的利润率在容器中重新定位组合框。

I tried to create a ComboBox dynamically, but cannot create it. Here is the code that I wrote.

        ComboBox com_dynamic = new ComboBox();            
        com_dynamic.Height = 50;
        com_dynamic.Width = 100;           
        LayoutRoot.Children.Add(com_dynamic);           
        tb.Margin = new Thickness(0, 145, 87, 0);
        tb.VerticalAlignment = VerticalAlignment.Top;
        tb.HorizontalAlignment = HorizontalAlignment.Right;

        ComboBoxItem com_dynamic_item = new ComboBoxItem();
        com_dynamic.AddChild(com_dynamic_item);
        com_dynamic_item.Content = "item1";

解决方案

You should also add the combobox to a container control. If you want to add it in the LayoutRoot, then this is the line you are missing.

LayoutRoot.Children.Add(com_dynamic);

You can reposition the combobox using its margin in the container.
