如下所示:<a title='<%# DataBinder.Eval(Container.DataItem,"InfoName")%>'
href='/InfoShow.aspx?InfoID=<%# DataBinder.Eval(Container.DataItem,"InfoID") %>' target="_blank">
<span style="CURSOR: hand">
<img src="images/news.jpg"></img>
<%# DataBinder.Eval(Container.DataItem,"InfoName") %>
</span>
</a>问题:
我通过sql查询最新10条记录显示,这个没有问题.
问题是我现在想在前台上述代码中将前面三条后面显示一个news图片,
就不知道该咋个弄了哈

将itemtemplate中的一个<asp:literal id="newpic" runat="server" />的内容指定为newpic.text="<img src=newpic.gif>"
<ItemTemplate>
<%# eval("usr") %><asp:Literal ID="pic" runat="server" /><br />
</ItemTemplate>
</asp:DataList>CodebehindDim dsn As String = "provider=microsoft.jet.oledb.4.0;data source=" & Server.MapPath("~/app_data/db1.mdb")
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not IsPostBack Then
Call bind_datalist()
End If
End Sub Function getdatasource() As DataTable Dim conn As New OleDbConnection(dsn)
Dim cmd As OleDbCommand = conn.CreateCommand
cmd.CommandText = "select id,usr from usrinfo"
Dim ad As New OleDbDataAdapter(cmd)
Dim ds As New DataSet
Dim tb As DataTable = Nothing
Try
ad.Fill(ds, "usrinfo")
Return ds.Tables("usrinfo")
Catch ex As Exception
Throw ex
Finally
conn.Dispose()
cmd.Dispose()
ad.Dispose()
ds.Dispose()
End Try End Function Sub bind_datalist()
DataList1.datasource = getdatasource()
DataList1.databind()
End Sub Protected Sub DataList1_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DataListItemEventArgs) Handles DataList1.ItemDataBound Select Case e.Item.ItemType
Case ListItemType.Item, ListItemType.AlternatingItem If e.Item.ItemIndex = 0 Or e.Item.ItemIndex = 1 Or e.Item.ItemIndex = 2 Then
CType(e.Item.FindControl("pic"), Literal).Text = "<img src=img/new.gif>"
End If End Select End Sub
codebehind 用 ItemDataBound 事件 来设定 前三条 的状态。

<%# DataBinder.Eval(Container.DataItem,"InfoName") %>
后面直接判断datalist的index进行处理?
如果能该咋个办?
如果不能为什么呢??
{
string strReturn = "";
SqlParameter[] pamNew = {
new SqlParameter("@varDocNo",SqlDbType.VarChar,15,ParameterDirection.Input, true, 0, 0, null, DataRowVersion.Current,strDocNo),
new SqlParameter("@varStaffNo",SqlDbType.VarChar,8,ParameterDirection.Input, true, 0, 0, null, DataRowVersion.Current,strStaffNo)
};
DataView dvNew = objDB.GetDataView("funGetBulletinVisitbyDocNo", pamNew);
if (dvNew.Count > 0)
{
if (dvNew.Table.Rows[0]["IfNewComment"].ToString().Trim() == "1")
strReturn = strReturn + "<img src='../images/comment.gif'>";
}
return strReturn;
}
前台调用::
<%# GetIfNew(DataBinder.Eval(Container.DataItem, "DocNo").ToString())%>自己改一改就可以了
