How to force DataGrid to rebuild VisualTree for its columns

I have WPF form with DataGrid. New columns can be added to the datagrid manually by user via button.

How to change 'sort glyph icon' color in DataGridView of Windows Form C#?

WPF-如何将 LayoutTransform 应用于特定的 DataGridColumnHeader(WPF- How to apply LayoutTransform to a specific DataGridColumnHeader)

问题 我有一个DataGrid其ItemsSource绑定到System.Data.DataTable 。 这个DataTable表在运行时填充了一些文本列和一些布尔列。 正如预期的那样,文本列显示为DataGridTextColumn ,布尔值显示为DataGridCheckBoxColumn 。 到目前为止没有问题。 现在我希望复选框列的列标题显示为垂直。 所以我定义了一个这样的样式: <Style x:Key="ColumnHeaderStyle" TargetType="{x:Type DataGridColumnHeader}"> <Style.Triggers> <!--<Trigger Property=??? Value=???> <Setter Property="LayoutTransform"> <Setter.Value> <RotateTransform Angle="270"/> </Setter.Value> </Setter> </Trigger>--> </Style.Triggers> </Style> 问题是 - 正如代码中所评论的那样,我不知道应该为样式使用哪种触发器才能仅应用于DataGridCheckBoxColumn而不应用于其他类型的列。 有任何想法吗? 回答1 要满足这两个要求: 时间:设置 ItemSource 后翻转标题过滤器

WPF- How to apply LayoutTransform to a specific DataGridColumnHeader

I have a DataGrid whose ItemsSource is bound to a System.Data.DataTable. This DataTable is filled at runtime with some text columns and some boolean columns. As expected, the text columns are displayed as DataGridTextColumn and the boolean ones are displayed as DataGridCheckBoxColumn. No problem so far. Now I want the column headers of the checkbox columns to be displayed as vertical. So I defined a style like this: <Style x:Key="ColumnHeaderStyle" TargetType="{x:Type DataGridColumnHeader}"> <Style.Triggers> <!--<Trigger Property=??? Value=???> <Setter Property="LayoutTransform"> <Setter.Value

WPF 4: What happened to DataGridColumnHeader?

What happened to DataGridColumnHeader? It looks like it was dropped when the DataGrid was moved into PresentationFramework.
