.net repeater的用法

     <div class="bbstextline">            <asp:Repeater ID="Repeater1" runat="server" DataSourceID="SqlDataSource1">            </asp:Repeater>            <asp:SqlDataSource ID="SqlDataSource1" runat="server"                 ConnectionString="<%$ ConnectionStrings:ConnectionString %>"                 SelectCommand="SELECT TOP 6 [zp_title] FROM [t5cms_jobinfo]">            </asp:SqlDataSource>        </div> 绑定数据源了啊，怎么用，急啊，谢谢各位了！

获取分页数据方法(多个排序字段)
/// <summary>
/// 获取分页数据(多个排序字段)
/// </summary>
/// <param name="pageSize">页面大小</param>
/// <param name="pageIndex">当前页索引</param>
/// <param name="recordCount">记录数</param>
/// <param name="where">查询条件</param>
/// <returns></returns>
public DataTable GetListManyOrderFile(int pageIndex, int pageSize, string table, string orderField, int orderType, string where, string key, out int recordCount)
{
if (where == null)
where = "";
OpenConn();
SqlCommand cmd = new SqlCommand("P_Page_ManyOrderFile", conn);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("@tblName", SqlDbType.VarChar, 800);
cmd.Parameters["@tblName"].Value = table;
cmd.Parameters.Add("@fldName", SqlDbType.VarChar, 255);
cmd.Parameters["@fldName"].Value = orderField;
cmd.Parameters.Add("@OrderType", SqlDbType.TinyInt);
cmd.Parameters["@OrderType"].Value = orderType;

cmd.Parameters["strWhere"].Value = where;
cmd.Parameters.Add("@doCount", SqlDbType.TinyInt);
cmd.Parameters["@doCount"].Value = 0;
cmd.Parameters.Add("@key", SqlDbType.VarChar,255);

SqlDataAdapter DA = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
DA.Fill(ds);
conn.Close();
conn.Dispose();
recordCount = GetRecordCount(table, where);
return ds.Tables[0];
}

返回记录数
/// <summary>
/// 返回记录数
/// </summary>
/// <param name="table">表名</param>
/// <param name="where">查询条件</param>
/// <returns></returns>
public int GetRecordCount(string table, string where)
{
int RecordCount = 0;
OpenConn();
SqlCommand cmd = new SqlCommand("TZFX_ZHDD_P_Page", conn);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("@tblName", SqlDbType.VarChar, 800);
cmd.Parameters["@tblName"].Value = table;
cmd.Parameters.Add("strWhere", SqlDbType.VarChar, 1500);
cmd.Parameters["strWhere"].Value = where;
cmd.Parameters.Add("@doCount", SqlDbType.TinyInt);
cmd.Parameters["@doCount"].Value = 1;
cmd.Prepare();
SqlDataReader dr = cmd.ExecuteReader(CommandBehavior.CloseConnection);
while (dr.Read())
{
RecordCount = int.Parse(dr[0].ToString());
}
//conn.Close();
//conn.Dispose();
dr.Close();
dr.Dispose();
return RecordCount;

}

Answer 2

我们一般不 是这样用的。 <asp:Repeater runat="server" ID="CustRep" OnItemDataBound="CustRep_ItemDataBound">
<ItemTemplate>
//中间绑定数据也可以写html 代码
<%#Eval("Cust_ContactMan") %>
</ItemTemplate>
</asp:Repeater>

后台只要
CustRep.DataSource = custTable;//custtable是你查询返回的结果集可以是datatable,也可以是dataset
CustRep.DataBind();

Answer 3

在页面中放一个Repeater 控件 里面有ItemTemplate节点 用表达式<%# 表达式%>指定你要绑定的数据
