         >
            <RowStyle BackColor="#F7F6F3" ForeColor="#333333" Font-Size="Small" />
            <Columns>
                <asp:BoundField DataField="punchdate" HeaderText="PUNCH DATE" />
                <asp:BoundField DataField="timein" HeaderText="IN TIME">
                <ItemStyle HorizontalAlign="Left" />
                 </asp:BoundField>
                <asp:BoundField DataField="timeout" HeaderText="OUT TIME">
                 </asp:BoundField>
            </Columns> 
           <FooterStyle BackColor="#5D7B9D"  ForeColor="White" />
                   <PagerStyle BackColor="#284775" ForeColor="White" HorizontalAlign="Center" />
            <selectedrowstyle backcolor="#E2DED6" forecolor="#333333" />
                   <HeaderStyle BackColor="#5D7B9D"  ForeColor="White" Font-Size="Medium" />
                  <EditRowStyle BackColor="#999999" />
                   <AlternatingRowStyle BackColor="PaleGoldenrod" />
        </asp:GridView>

和pageindexedchange事件代码

and pageindexedchange event code

protected void GridView1_PageIndexChanging(object sender,GridViewPageEventArgs e)
       {
          GridView1.PageIndex = e.NewPageIndex;
           GridView1.SelectedIndex = -1;
                 }

我该怎么办?

What should I do?

推荐答案

看起来像您忘记了重新绑定gridview一样.您需要做的就是增加页数并重新绑定网格. .NET将自动显示正确的行.

在这里，请看以下示例文章:
MSDN:ASP.NET 2.0的GridView示例:对GridView的数据进行分页和排序 [ ^ ]
ASP.NET中的GridView分页示例 [ ^ ]

Looks like you forgot to rebind the gridview. All you need to do is increase the page count and rebind the grid. .NET will automatically show the correct rows.

Here, have a look at these sample article:
MSDN: GridView Examples for ASP.NET 2.0: Paging and Sorting the GridView''s Data[^]
GridView Paging Sample in ASP.NET[^]

再次绑定网格视图...

Bind your gridview again...

GridView1.PageIndex = e.NewPageIndex;
GridView1.SelectedIndex = -1;
bindgrid();

谢谢

Thanks

创建会话

Session["grid"] = ds;
protected void GridView1_PageIndexChanging(object sender,GridViewPageEventArgs e)
        {
           GridView1.PageIndex = e.NewPageIndex;        
            GridView1.SelectedIndex = -1;
GridView1.DataSource=Session["grid"] ;
GridView1.DataBind();
                  }
