Question

<td><asp:RadioButton ID="RadioButton1" runat="server" Width="1px" GroupName="1" Height="1px" Text=" " OnCheckedChanged="RadioButton1_CheckedChanged"  /><asp:Image ID="Image1" runat="server" Height="70%" Width="31%" ImageUrl="~/pic/01.jpg" /></td>有五个RadioButton控件，当我选择其中一个时候，把旁边的Image 的 ImageURL插入到 数据库中（字段时src）由于本人新手 会的少只能用最简单的方法，请前辈指点。String strinto = "insert into [message] ([src]) values ('"+strSRC+"')";protected void RadioButton1_CheckedChanged(object sender, EventArgs e)
    {
