Answer 1

可以通过dataList来实现
 <asp:DataList ID="DataList1" runat="server" RepeatColumns="3">
                                    <ItemTemplate>
                                    <br/>
                                    <table border="0" style=" padding-top:4px;">
                                    <tr>
                                    <td>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</td>
                                       <td>
                                       <table style=" text-align:center;">
                                            <tr >
                                                <td  align="center">
                                                <a href="Deteils.aspx?id=<%# Eval("id") %>">
                                                    <asp:Image ID="Image1" runat="server" ImageUrl='<%# getImage((Eval("imgUrl")).ToString()) %>' Width="130px" Height="80px" />
                                                 </a>
                                                 </td>
                                            </tr>
                                            <tr>
                                                <td align="center">
                                                <a href="Deteils.aspx?id=<%# Eval("id") %>">
                                                    <asp:Label ID="Label1" runat="server" Text='<%# Eval("title") %>'></asp:Label>
                                                 </a>
                                                 </center>
                                                 </td>
                                            </tr>
                                        </table>
                                        </td>
                                    </tr>
                                    </table>
                                    </ItemTemplate>
                                    </asp:DataList>
这是我页面上显示3列图片的代码

Answer 2

这个简单，点左边的LinkButton，发生click事件，为该事件写代码，改变右边Image的地址即可。

Answer 3

string[] imgs="1.JPG,2.JPG".Split(',')
for(int i=0;i<imgs.lenght,i++){
 
}

Answer 4

听你讲得好容易的.....但我特别蠢"改变右边Image的地址"这里不知道怎样显实，加上图片地址在数据库里

Answer 5

    可以通过Repeter来绑定数据！你在表里给他们加个标识字段，作为改变URL的条件。然后根据标识字段查出来就可以了！不知道我说的是否清楚。 - -！

Answer 6

    OleDbConnection cn = new OleDbConnection();     
    protected void Page_Load(object sender, EventArgs e)
    {
        
        if (!IsPostBack)
        {  
            cn.ConnectionString = ConfigurationManager.ConnectionStrings["con1"].ToString();
            string sqlstr = "select top 2 * from [GoodsInfo] where GoodsIsNew='Yes' order by GoodsDate desc ";
            cn.Open();
            OleDbDataAdapter myda = new OleDbDataAdapter(sqlstr,cn);
            DataSet myds = new DataSet();
            myda.Fill(myds,"GoodsInfo1");
            DataRowView mydrv = myds.Tables["GoodsInfo1"].DefaultView[0];
            ibtnGName.ImageUrl = Convert.ToString(mydrv.Row["GoodsPhoto"]);
            hlinkGName.Text = Convert.ToString(mydrv.Row["GoodsName"]);
            hlinkGName.NavigateUrl = "~/UserManage/EditGInfo.aspx?GoodsID=" + Convert.ToString(mydrv.Row["GoodsID"]) + "";
            DataRowView mydrv1 = myds.Tables["GoodsInfo1"].DefaultView[1];
            ibtnGoods2.ImageUrl = Convert.ToString(mydrv1.Row["GoodsPhoto"]);
            hlinkG2.Text = Convert.ToString(mydrv1.Row["GoodsName"]);
            hlinkG2.NavigateUrl = "~/UserManage/EditGInfo.aspx?GoodsID=" + Convert.ToString(mydrv1.Row["GoodsID"]) + "";        }    }
LZ参考下吧,这是HyperLink 和 ImageButton 的一些关系，这个实现的功能是读取数据库的路径，显示图片，然后如果点击HyperLink就在目标框架显示产品内容。
这个可能有点跟LZ不同，仅供参考
