Gridview模板显示数据库中图像问题
我在做C#.net的web网页应用开发
数据库中存有手机信息以及相应的图片路径，数据库存的是图片相对路径，如：~/Images/1.jpg，然后想用个gridview模板把手机的信息以及其对应的图片显示出来，形成个列表。

下面是前台代码：
<asp:GridView ID="GridView1" runat="server" Width="100%"  
  AutoGenerateColumns="False" Font-Size="Small" Height="16px" 
  style="margin-right: 0px" 
  EmptyDataText="No Records" PageSize="5" ShowHeader="False" onselectedindexchanged="GridView1_SelectedIndexChanged" 
  >
  <Columns>
  <asp:TemplateField>  
  <ItemTemplate>
  <table style=" border:1px thin solid #6699FF; width:100%" >
  <tr>
  <td style="border-color: #00FFFF; height: 19px; text-align: left;"> 
   
  Product ID：<font color='#FF0000'><%# DataBinder.Eval(Container.DataItem, "pid")%></font>&nbsp; &nbsp;
  Product Name：<font color='#FF0000'><%# DataBinder.Eval(Container.DataItem, "pname")%></font>&nbsp; &nbsp;Model:<font color='#FF0000'><%# DataBinder.Eval(Container.DataItem, "model")%></font><br />color：<font color='#FF0000'><%# DataBinder.Eval(Container.DataItem, "color")%></font>&nbsp; &nbsp; Material Quality：<font color='#FF0000'><%# DataBinder.Eval(Container.DataItem, "materialquality")%></font>Quantity：<font color='#FF0000'><%# DataBinder.Eval(Container.DataItem, "quantity")%></font><br />Import Price: <font color='#FF0000'><%# DataBinder.Eval(Container.DataItem, "importprice")%></font>&nbsp; &nbsp; Sale Price: <font color='#FF0000'><%# DataBinder.Eval(Container.DataItem, "saleprice")%></font>&nbsp; &nbsp; Supplier <font color='#FF0000'><%# DataBinder.Eval(Container.DataItem, "supplier")%></font>&nbsp; &nbsp;
  <br />Image:<font color='#FF0000'><%# DataBinder.Eval(Container.DataItem, "image")%></font>&nbsp; &nbsp; Description: <font color='#FF0000'><%# DataBinder.Eval(Container.DataItem, "description")%></font>&nbsp; &nbsp;</tr>
   
   
  <asp:Image ID="Image1" runat="server" ImageUrl='<%# DataBinder.Eval(Container.DataItem, "image").ToString)%>'/>
  </table>
  </ItemTemplate>
  </asp:TemplateField>
  </Columns>
  </asp:GridView>

后台代码：
  protected void bind()
  {
  String qs = "select pid, pname, model, color, materialquality, importprice, saleprice, quantity, supplier, image, description from product ";
  DB dbb = new DB();
   
  DataSet ds = dbb.GetData(qs);//GetData(queryString);
  if (ds.Tables.Count > 0)
  {
