C# 单击列时要编辑的Gridview弹出窗口

我有一个网格视图。我需要包括一个超链接到其中一列，所以当用户点击链接时，弹出窗口应该带有编辑和保存选项。保存后，gridview将自动刷新

以下是我的Gridview代码：

 <asp:GridView ID="EmployeeGridView" runat="server" AutoGenerateColumns="False"
               DataKeyNames="Emp_id" onrowcancelingedit="EmployeeGridView_RowCancelingEdit"

               onrowupdating="EmployeeGridView_RowUpdating" Width="395px" 
               CellPadding="4" ForeColor="#333333" GridLines="None" 
               onrowdatabound="EmployeeGridView_RowDataBound" AllowPaging="True" 
               onpageindexchanging="EmployeeGridView_PageIndexChanging1" PageSize="5">
