wpf - 在列之间单击以固定大小，消除了我的大小设置 - WPF DataGrid

Question

我在 DataGrid 中通过以下方式定义了列的大小：

<DataGrid x:Name="DG" ItemsSource="{Binding X}" AutoGenerateColumns="False" ColumnWidth="*">

这工作正常，直到我在两列之间按下以查看特定列的全部内容的那一刻，然后他不知道我对该列的定义，并通过其内容增加了超出必要的列。

为什么会发生这种情况以及如何预防？

您可以通过使用此站点的样式来防止这种情况：http: //msdn.microsoft.com/en-us/library/ff506248.aspx并从中删除：PART_LeftHeaderGripper和PART_RightHeaderGripper。
