我想以编程方式创建一个带有样式的基本用户控件.在这种风格中我想添加一个Grid(没问题),但是我不能在这个网格中添加列定义.

我的示例代码是

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

headerImg.SetValue(Image.HeightProperty, 32d);
headerImg.SetBinding(Image.SourceProperty, new Binding("ElementImage") { RelativeSource = new RelativeSource(RelativeSourceMode.TemplatedParent) });
headerPanel.AppendChild(headerImg);

FrameworkElementFactory headerTitle = new FrameworkElementFactory(typeof(TextBlock));
headerTitle.SetValue(TextBlock.FontSizeProperty, 16d);
headerTitle.SetValue(TextBlock.VerticalAlignmentProperty, VerticalAlignment.Center);
headerTitle.SetBinding(TextBlock.TextProperty, new Binding("Title") { RelativeSource = new RelativeSource(RelativeSourceMode.TemplatedParent) });
headerPanel.AppendChild(headerTitle);

FrameworkElementFactory mainGrid = new FrameworkElementFactory(typeof(Grid));
FrameworkElementFactory c1 = new FrameworkElementFactory(typeof(ColumnDefinition));
c1.SetValue(ColumnDefinition.WidthProperty, new GridLength(1, GridUnitType.Star));
