將超級標題列綁定到代碼中的DataGrid列寬

我創建了一個綁定到數據網格的超級標頭網格。在調整datagrid列的大小時，超級標頭會保留在其各自的datagrid列上。將超級標題列綁定到代碼中的DataGrid列寬

XAML綁定是偉大的，一切工作正常。

但是，唯一的問題是我需要能夠在C＃代碼中動態構造這個。嘗試了很多方法，但我無法使綁定工作。

什麼是以下XAML的C＃等效物

謝謝。

應相當於：

綁定cdBinding =新的Binding（「RowHeaderWidth」）; cdBinding.Source = DetailDataGrid;

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

SuperHeaderGrid.ColumnDefinitions.Add（colDef）;

對於其他列定義也是類似的。
