WPF后台生成datatemplate（TreeViewItem例子）

public void loadCheckListDataTemplate(TreeViewItem tvi)

{

DataTemplate cdt = new DataTemplate();

FrameworkElementFactory cfef = new FrameworkElementFactory(typeof(StackPanel));

cfef.SetValue(StackPanel.OrientationProperty, Orientation.Horizontal);

Binding binding = new Binding();

FrameworkElementFactory subfef1 = new FrameworkElementFactory(typeof(TextBlock));

subfef1.SetValue(TextBlock.TextProperty, binding);

subfef1.SetValue(TextBlock.MarginProperty, new Thickness(0, 0, 5, 0));

cfef.AppendChild(subfef1);

FrameworkElementFactory subfef2 = new FrameworkElementFactory(typeof(CheckBox));

subfef2.SetValue(CheckBox.ContentProperty, "添加");

subfef2.SetValue(CheckBox.MarginProperty, new Thickness(0, 0, 5, 0));

cfef.AppendChild(subfef2);

FrameworkElementFactory subfef3 = new FrameworkElementFactory(typeof(CheckBox));

subfef3.SetValue(CheckBox.ContentProperty, "修改");

subfef3.SetValue(CheckBox.MarginProperty, new Thickness(0, 0, 5, 0));

cfef.AppendChild(subfef3);

FrameworkElementFactory subfef4 = new FrameworkElementFactory(typeof(CheckBox));

subfef4.SetValue(CheckBox.ContentProperty, "删除");

subfef4.SetValue(CheckBox.MarginProperty, new Thickness(0, 0, 5, 0));

cfef.AppendChild(subfef4);

cdt.VisualTree = cfef;

tvi.HeaderTemplate = cdt;
