我正在开发 vb.net windows 应用程序。我有一个网格视图..我正在填充我的数据网格视图，如下所示：

在加载事件中我写了这样的代码：

Dim cd As SqlCommandBuilder = New SqlCommandBuilder(adapter)
        adapter = New SqlDataAdapter("select c.cid,c.CompanyName,d.dtId,d.dtName as Department,d.dtPhone as Phone,d.dtEmail as Email,d.empimage as Image from CompanyMaster_tbl c join  DepartmentMaster_tbl d on c.Cid=d.cId order by cid", con.connect)
        dt1 = New DataTable
        bSource = New BindingSource
        adapter.Fill(dt1) 'Filling dt with the information from the DB
        bSource.DataSource = dt1
        gv.DataSource = bSource
        gv.Columns("cid").Visible = False
        gv.Columns("dtId").Visible = False

所以我的网格视图是这样的：

我想在我的图像列中添加按钮..所以我尝试这样的代码：但这就是再添加一列。

 Dim btn As New DataGridViewButtonColumn
        gv.Columns.Insert(6, btn).  

那么我如何在我的图像列中添加按钮
