Repeater添加图片问题!
我的cs 文件代码如下！
private void BindGood()
{
string strsql = @ "select top 5 ( 'BBS_ReferList.aspx?SectionId= '+CAST (S.SectionID as varchar(14))) as url ,S.SectionName, R.Hits
from BBS_Sections as S Inner Join (select top 5 SectionID,Hits from BBS_Refers order by Hits desc) as R On S.SectionID = R.SectionID ";
DataSet objds = new DataSet();
objds = SqlHelper.ExecuteDataset(Operate.SqlConn,CommandType.Text,strsql);
try
{
Repeater1.DataSource = objds.Tables[0];
Repeater1.DataBind();
}
catch(Exception error)
{
Response.Write(error.ToString());
}
}
页面邦定代码如下:
<asp:repeater id= "Repeater1 " runat= "server ">
<ItemTemplate>
<asp:Image id= "Image2 " runat= "server " ImageUrl= "../image/bbs_1.gif " Width= "14px " Height= "15px "> </asp:Image>
<a href= ' <%#DataBinder.Eval(Container.DataItem, "url ")%> '>
<%#DataBinder.Eval(Container.DataItem, "SectionName ")%>
</a> （ <%#DataBinder.Eval(Container.DataItem, "Hits ")%> ）
<br>
</ItemTemplate>
</asp:repeater>
我现在想做的事情是Repeater每换一行输出数据我就把前面的图片换成另外一个
image/bbs_1.gif；
也就是说，Repeater如果输出5行数据（每行一列）的话！平时前面会有5个一样的图标。我想把把这个图片换成5 个不同的图片。。。怎么办？谢谢！
