c# - 在devexpress xtragrid中单击columnheader时选择columnwise？

Question

我正在使用 devexpress 16.1，我将我的数据表绑定(bind)到 xtragrid，现在我想在单击列标题时按列选择，如果有任何选项可以通过 xtragrid 实现此目的的话。

这些都是我尝试过的，

gridview1.optionsselection.multiselect = True
gridview1.optionsselection.multiselectMode = cellselect

试试这段代码:(使用 Gridcontrol 鼠标按下事件)

VB.net:
 Dim hitInfo = GridView1.CalcHitInfo(e.Location)  
If e.Button = Windows.Forms.MouseButtons.Left Then 
    For Each column As GridColumn In GridView1.Columns  
       If column.FieldName = hitInfo.Column.FieldName Then 
            hitInfo.Column.AppearanceCell.BackColor = Color.FromArgb(226, 234, 253)                       
       Else
            GridView1.Columns(column.FieldName).AppearanceCell.BackColor = Nothing
       End If
    Next
End If

 C#: 
var hitInfo = GridView1.CalcHitInfo(e.Location);
if (e.Button == Windows.Forms.MouseButtons.Left) 
{
    foreach (GridColumn column in GridView1.Columns) 
    {
       if (column.FieldName == hitInfo.Column.FieldName) 
        {
            hitInfo.Column.AppearanceCell.BackColor = Color.FromArgb(226, 234, 253);
        }
        else 
        {
        GridView1.Columns(column.FieldName).AppearanceCell.BackColor = null;
        }
    }
}

调用 GridView.CalcHitInfo 方法获取行句柄。然后焦点移动到该行并调用自定义上下文菜单。
