GRIDVIEW分页问题

Question

出错的原因是你的分页方法里面少了一条语句
DataSet   ds   =   GetCarList(); 
this.gdvCarList.DataSource   =   ds; 把绑定方法提取出来好一点。
private void Bind()
{
    this.gdvCarList.DataSource   =   GetCarList(); 
                
    gdvCarList.DataBind(); }在你的分页方法里面调用。
Bind()方法。

Answer 1

应该不是page_load()引起的
应该是引起的:
protected   void   gdvCarList_PageIndexChanging(object   sender,   GridViewPageEventArgs   e)
        {
                gdvCarList.PageIndex   =   e.NewPageIndex;
                gdvCarList.DataBind();
        } 因为你只给出了gdvCarList.DataBind();,有了绑定方法,你还的绑定数据源,我想应该是这样的,我一直这样做没有出现过问题
protected   void   gdvCarList_PageIndexChanging(object   sender,   GridViewPageEventArgs   e)
        {
                gdvCarList.PageIndex   =   e.NewPageIndex;
                DataSet   ds   =   GetCarList();
                this.gdvCarList.DataSource   =   ds;               
                gdvCarList.DataBind();
        } 

Answer 2

感谢各位大哥，但我现在加了这两条语句，
                                     DataSet       ds       =       GetCarList(); 
                                this.gdvCarList.DataSource       =       ds;
还是报索引超出范围，真急啊：

Answer 3

DataSet ds=GetCarList();   
gdvCarList.PageIndex = e.NewPageIndex;
gdvCarList.DataSource = ds;
gdvCarList.DataBind();

Answer 4

private void Bind()
{
    this.GridView1.DataSource = (DataSet)this.ViewState["ds"];
    this.GridView1.DataBind();
}
private void Page_Load(.....,.....)
{
    if(!Ispostback)
    {
        DataSet ds = new DataSet();
        假设ds已经有了内容
         .................
        this.ViewState["ds"] = ds;
        Bind();
    }
}protected void gdvCarList_PageIndexChanging(...,....) 
{ 
   this.GridView1.PageIndex = e.NewPageIndex; 
   Bind();
}

ASP.NET 2.0中Gridview的分页与排序
remex 著于2007-9-6 9:02:56
ASP.NET 2.0中，Gridview取代了以前的datagrid控件,本文解释如何在Gridview控件中进行分页、排序以及添加按钮控件(控制其显示/隐藏)。

Answer 6

(1) 你先单独写个数据绑定的方法，如：
pulic void DataBound()
{
     DataSet   ds   =   GetCarList(); 
     this.gdvCarList.DataSource   =   ds;
     this.gdvCarList.DataBind();
}(2)分页代码
protected   void   gdvCarList_PageIndexChanging(object   sender,   GridViewPageEventArgs   e) 
        { 
                gdvCarList.PageIndex   =   e.NewPageIndex1; 
                DataBound（）  //调用上面的绑定方法
          } 
附：如果： gdvCarList.PageIndex   =   e.NewPageIndex1;出来的效果还是不对，那你用 gdvCarList.PageIndex   =   e.NewPageIndex1-1试下看看;
（3）
protected   void   Page_Load(object   sender,   EventArgs   e) 
        { 
                 if (!Page.IsPostBack)
                   { 
                        DataBound（）;  //调用上面的绑定方法
                     }
        {
        }

Answer 8

分页后点查看时总在红字处报索引超出范围。但若是第一页就不会报错。
case   "Detail": 
                                Button   btn   =   e.CommandSource   as   Button; 
                                GridViewRow   row   =   btn.Parent.Parent   as   GridViewRow;                                 string   strCarDtl   =   this.gdvCarList.DataKeys[row.DataItemIndex].Value.ToString().Trim(); 
                                //string   strCarDtl   =   this.gdvCarList.Rows[row.DataItemIndex].Cells[1].Text.ToString().Trim(); 
                                Response.Redirect("/WebSys/Sys/CarInfoDetail.aspx?valueId="   +   strCarDtl); 
                                break;
