Winforms 调整DevExpress XtraGrid列大小时的命中测试不正确

自定义排序和列大小调整不起作用

但是，在MouseUp事件处理程序上实现了自定义排序

if ( hitInfo.InColumnPanel && hitInfo.HitTest == GridHitTest.ColumnEdge)
{
   (e as DXMouseEventArgs).Handled = true;
    return;
}

不适用于该事件

希望能够通过拖动列边缘来单击列标题进行排序和调整大小

private void OnMouseDown(object sender, MouseEventArgs e)
{
   GridHitInfo hitInfo = gridView1.CalcHitInfo(e.Location);
   if (hitInfo.HitTest == GridHitTest.ColumnEdge)
   {
      isEdgeClicked = true;
   }
}

private void OnMouseUp(object sender, System.Windows.Forms.MouseEventArgs e) 
{
   if (isEdgeClicked)
   {   isEdgeClicked = false;
       return;
   }
   else 
   {
      (e as DXMouseEventArgs).Handled = true;
   }
}
