Winforms DataGridViewresize问题
我不是100％肯定我应该如何说出这个问题，但我会尽我所能。
我有一个PointCtrlForm，在TableLayoutPanel中有一个DataGridView。 DataGridView作为Fill停靠在表中。 PointCtrlForm停靠在另一个设置为MDIParent的窗口，并将dockstyle属性设置为Fill。
正确调整主窗口的大小可以调整PointCtrlForm的大小，然后也可以调整DataGridView的大小。 好吧，至少“一半”的resize正常。 扩大主窗口也会扩大datagridview，这是我的预期，但如果我将主窗口缩小到某个点，DataGridView会停止收缩并隐藏列而不显示滚动条。
我已检查所有列都没有启用Frozen属性，检查datagridview和子窗口是否已正确停靠，并检查scrollbars属性是否设置为两者。
编辑：AutoSizeColumnsMode也填充。
我将在这里发布Designer.cs的内容。 我很感激任何指导。

DGV的行和列大小必须设置为“百分比（相对）”而不是“绝对”，以使对接正常工作。
您可以通过右键单击DGV的其中一个单元格并单击“编辑行/列属性”来编辑大小。
