Question

我创建了一个绑定到数据网格的超级标头网格。在调整datagrid列的大小期间，超级标头会在各自的datagrid列上保持定位。

XAML绑定很棒，一切正常。

唯一的问题是，我需要能够在C＃代码中动态构造它。尝试了许多方法，但我无法使绑定工作。

以下XAML的C＃等价物是什么

感谢。

Answer 1

应该相当于：

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

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

SuperHeaderGrid.ColumnDefinitions.Add（colDef）;

类似于其他列定义。
