如何在GridView中隱藏自動生成的刪除按鈕

Question

如何在GridView中隱藏自動生成的刪除按鈕。 無法使僅刪除按鈕不可見。 同時使“刪除”按鈕，“取消”按鈕不可見的操作也變得不可見。

取消按鈕也變得不可見

 <asp:GridView ID="gvCompanies" runat="server" CssClass="mydatagrid" PagerStyle-CssClass="pager"
            HeaderStyle-CssClass="header" RowStyle-CssClass="rows"

 if (e.Row.RowType == DataControlRowType.DataRow)
                {
                    // Hide the edit button when some condition is true
                    // for example, the row contains a certain property
                     if (Loggedinuser != "kernel")

                   e.Row.Cells[0].Controls[2].Visible = false;


                }


                }

有兩個選項可隱藏或顯示GridView中的特定列

選項1：使用單元格索引

 protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
        {
          if (e.Row.RowType == DataControlRowType.DataRow)
                {
                if("your Condition")
                  {

                    e.Row.Cells[0].Control[0].Visible = false;//or true
                    }
                 }        
         }

選項2：遍歷GridView行控件集合

protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
    {


            foreach (TableRow row in GridView1.Controls[0].Controls)
            {
             if("your Condition")
                      {
                      row.Cells[0].Control[0].Visible = false;
                      }
            }        
    }
