开始学.Net时写的分页类

public PagedDataSource GetPagedDataSource(DataSet MyDataSet,int PageSize,int PageNum,string AspxName,Label PageLable)

{

PagedDataSource PDS=new PagedDataSource();

PDS.AllowPaging=true;

PDS.PageSize=PageSize;

PDS.DataSource=MyDataSet.Tables[0].DefaultView;

int CurrentPage=0;

if(Convert.ToString(PageNum)!=null)

{

CurrentPage=int.Parse(PageNum.ToString());

}

else

{

CurrentPage=1;

}

PDS.CurrentPageIndex=CurrentPage-1;

int PageCount=PDS.PageCount;

string FirstPage=(PageNum==1)?("9"):("9");

string PrevPage=(PageNum==1)?("7"):("7");

string NextPage=(PageNum==(PageCount))?("8"):("8");

string LastPage=(PageNum==(PageCount))?(":"):(":");

­

PageLable.Text="总记录: "+PDS.DataSourceCount+"   每页: "+PageSize+"   总页数: "+PageCount+""+FirstPage+"  "+PrevPage+"  "+NextPage+"  "+LastPage+"";

­

return PDS;

}

调用示例

//PagedDataSource分页

string MySql="Select * from C_Company";

int PageNum=(Request.QueryString["Page"]==null)?(1):(Convert.ToInt32(Request.QueryString["Page"]));

MyDataSet=MyData.GetDataSet(MySql,0,0,"Table");

PagedDataSource PDS=new PagedDataSource();

PDS=MyData.GetPagedDataSource(MyDataSet,10,PageNum,Request.CurrentExecutionFilePath+"?",Label1);

this.DataGrid1.DataSource=PDS;

this.DataGrid1.DataBind();
