c# access,Dataset及數據綁定

先看下後臺代碼，數據庫用的是access.

designers.aspx.cs:

using System.Collections;
using System.Text;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

public partial class Designers : System.Web.UI.Page
{
        protected void Page_Load(object sender, EventArgs e)
        {
                string strConn = System.Web.Configuration.WebConfigurationManager.ConnectionStrings["connStr"].ConnectionString;
                OleDbConnection Conn = new OleDbConnection(strConn);
                string StrComm = string.Empty;
                StrComm = "select    id,Dname,jieshao from [designers] ";
                OleDbDataAdapter Comm = new OleDbDataAdapter(StrComm, Conn);

                DataSet ds = new DataSet();                                                     //DataSet 初試化
                Comm.Fill(ds, "Book");
                designers.DataSource = ds.Tables["Book"].DefaultView;
                designers.DataBind();
                     }


        protected string CutLongString(string longString, int charNum)
        {
                if (longString.Trim().Length > charNum)
                {
                        return longString.Substring(0, charNum);
                }
                else return longString.Trim();
        }        


}

前臺綁定：

<asp:DataList ID="designers" runat="server"    RepeatColumns="2"    
                RepeatDirection="Horizontal"    
             >
        <ItemTemplate>
        <br />
         <div id="designtable">
        <div id="fenleitiaomu"><img src="designers/<%# Eval("id")%>.jpg"    alt="" /> <a href="product.aspx?classid=<%# Eval("id")%>" target="_blank"><%# Eval("Dname")%></a>
        
        </div>
         <%# CutLongString(DataBinder.Eval(Container.DataItem,"jieshao").ToString(),12)%>        
        <div>    
                 </div>
        </div>

        </ItemTemplate>
        </asp:DataList>

web.config

<connectionStrings>
        <add name="connStr" connectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|\data.mdb" providerName="System.Data.OleDb"/>
    </connectionStrings>
