请问大家,DataList与Repeater如何实现分页？
解决方案
解决方案二：
用pagedatasource，如果有需要，我把源代码给你其实你也可以看一下这个http://www.lokcore.com/avrilxu/article.asp?id=5repeater的详解

解决方案四：
可以试用pagedatasource这个类，提供了分页的功能，不过数据量太大的话效率不是很高。我的一个例子楼主可以看一下：publicpartialclassRepeterExcerise:System.Web.UI.Page{stringConStr=ConfigurationManager.ConnectionStrings["NorthwindConnectionString"].ConnectionString;SqlConnectionCon;protectedvoidPage_Load(objectsender,EventArgse){if(!IsPostBack){//设置默认的排序顺序ViewState["CompanyName"]="SupplierID";ViewState["Direction"]="ASC";ViewState["LineNo"]=0;//初始化的时候默认显示第一页lblCount.Text="1";BindRepeter();}}//判断命令protectedvoidRepeater1_ItemCommand(objectsource,RepeaterCommandEventArgse){StringIndex=((Label)Repeater1.Items[e.Item.ItemIndex].FindControl("lblID")).Text;Session["ID"]=Index;//编辑模式if(e.CommandName=="Edit"){stringCompanyName=((Label)(Repeater1.Items[e.Item.ItemIndex].FindControl("lblCompanyName"))).Text;stringName=((Label)(Repeater1.Items[e.Item.ItemIndex].FindControl("lblName"))).Text;stringAddress=((Label)(Repeater1.Items[e.Item.ItemIndex].FindControl("lblAddress"))).Text;stringCity=((Label)(Repeater1.Items[e.Item.ItemIndex].FindControl("lblCity"))).Text;txtCompanyName.Text=CompanyName;txtContactName.Text=Name;txtAddress.Text=Address;txtCity.Text=City;if(Panel1.Visible==false){ShowMessage("进入编辑模式");}SetDisplayTrue();btnInsert.Visible=false;btnUpdate.Visible=true;Button1.Visible=true;}//删除elseif(e.CommandName=="Delete"){if(Panel1.Visible==true){ShowMessage("编辑模式下禁止删除");}else{SetDisplayFalse();stringDeleteStr="DELETEFROMSuppliersWHERESupplierID='"+Index+"'";Con=newSqlConnection(ConStr);SqlCommandDeleteCmd=newSqlCommand(DeleteStr,Con);try{Con.Open();DeleteCmd.ExecuteNonQuery();ShowMessage("删除成功");BindRepeter();}catch(Exceptionex){ShowMessage("删除有错误，请检查");}finally{Con.Dispose();}}}//新增elseif(e.CommandName=="New"){if(Panel1.Visible==true){ShowMessage("编辑模式下禁止添加新行");}else{SetDisplayTrue();ClearWord();btnInsert.Visible=true;btnUpdate.Visible=false;Button1.Visible=true;}}}//绑定RepeterprivatevoidBindRepeter(){stringQueryCon="SELECTSupplierID,CompanyName,ContactName,Address,CityFROMSuppliers";Con=newSqlConnection(ConStr);SqlDataAdapterNorthWindDa=newSqlDataAdapter(QueryCon,ConStr);DataSetDs=newDataSet();NorthWindDa.Fill(Ds,"Suppliers");//Repeater1.DataKeyNames=newstring[]{"SupplierID"};DataViewDv=Ds.Tables["Suppliers"].DefaultView;//排序表达式stringSortExpress=(string)ViewState["CompanyName"]+""+(string)ViewState["Direction"];Dv.Sort=SortExpress;//绑定数据源//Repeater1.DataSource=Ds.Tables["Suppliers"];//利用PagedDataSource进行分页PagedDataSourcePageDs=newPagedDataSource();PageDs.DataSource=Dv;PageDs.AllowPaging=true;PageDs.PageSize=10;intCurrentPage=Convert.ToInt32(lblCount.Text);//当前页PageDs.CurrentPageIndex=CurrentPage-1;btnPage.Enabled=true;Button2.Enabled=true;if(CurrentPage==1){Button2.Enabled=false;}if(CurrentPage==PageDs.PageCount){btnPage.Enabled=false;}//PageCount=PageDs.PageCount;lblPage.Text="共"+PageDs.PageCount+"页,当前在第";//将PageDs作为数据源进行绑定Repeater1.DataSource=PageDs;Repeater1.DataBind();}//显示编辑区域privatevoidSetDisplayTrue(){lblCompanyName.Visible=true;lblName.Visible=true;lblAddress.Visible=true;lblCity.Visible=true;txtCompanyName.Visible=true;txtContactName.Visible=true;txtAddress.Visible=true;txtCity.Visible=true;Panel1.Visible=true;}//隐藏编辑区域privatevoidSetDisplayFalse(){lblCompanyName.Visible=false;lblName.Visible=false;lblAddress.Visible=false;lblCity.Visible=false;txtCompanyName.Visible=false;txtContactName.Visible=false;txtAddress.Visible=false;txtCity.Visible=false;Panel1.Visible=false;}}
