应该可以帮助您的一个因素是:
DataGridView.ColumnDividerWidthChanged事件 [

Bookmark this page for yourself: DataGridView Events[^]

The one that should help you out is:
DataGridView.ColumnDividerWidthChanged Event[^]

这是DataGridView
的ColumnWidthChanged事件
调整父窗体的大小时，您必须过滤掉此事件触发.使用ResizeBegin设置一个正在调整大小的标志，使用ResizeEnd重置该标志.

另外，您还必须知道用户正在调整哪一列的大小.为此使用MouseDown事件.

It is the ColumnWidthChanged event of the DataGridView

You''ll have to filter out this event firing when parent form is resized. Use ResizeBegin to set a flag that form is resizing and ResizeEnd to reset the flag.

Also you''ll have to know which column is being resized by user. Use MouseDown event for this.

private void dataGridView_MouseDown(object sender, MouseEventArgs e)
{
    for (int i = 0; i < dataGridView.ColumnCount; i++)
    {
        if (dataGridView.GetColumnDisplayRectangle(i, true).Contains(e.Location))
        {
            columnBeingResized = dataGridView.Columns[i];
            break;
        }
    }
}
