将超级标题列绑定到代码中的DataGrid列宽

我创建了一个绑定到数据网格的超级标头网格。在调整datagrid列的大小时，超级标头会保留在其各自的datagrid列上。将超级标题列绑定到代码中的DataGrid列宽

XAML绑定是伟大的，一切工作正常。

但是，唯一的问题是我需要能够在C＃代码中动态构造这个。尝试了很多方法，但我无法使绑定工作。

什么是以下XAML的C＃等效物

谢谢。

应相当于：

绑定cdBinding =新的Binding（ “RowHeaderWidth”）; cdBinding.Source = DetailDataGrid;

ColumnDefinition colDef = new ColumnDefinition（）; colDef.SetBinding（ColumnDefinition.WidthProperty，cdBinding）;

SuperHeaderGrid.ColumnDefinitions.Add（colDef）;

对于其他列定义也是类似的。
