gridview分页的实现(winform datagridview 分页)
ASP.NET中 gridview 结合 sqldatasource 使用控件 AspNetPaper 进行分页显示。

asp.net gridview分页问题(急)？
（1）写查询语句的方法
public Dataset xxx(string searchString)
{
if(判断searchString是否是空)
{
//如果为空，查询语句为string sql="select xx from xxxx"
//如果不为空，查询语句为string sql="select xx from xxxx where ……"
}
//然后执行查询语句
}
（2）将gridview绑定数据源写一个独立的方法
比如：private void Gvbind()
{
Dataset ds=new Dataset();
if(判断搜索框中是否为空)
……
//如果搜索框为空则ds=xxx(null);
//如果搜索框不为空则ds=xxx(搜索框中的文本);
然后将数据源绑定到Gridview
}
（3）接下来凡是要绑定时都调用Gvbind()方法
gridview如何分页控制显示的行数？大虾帮帮忙
这个要用2个文件，一个是在页面中设置GridView，如：PagerTemplate
table width="100%"
tr
td style="text-align:center"
当前 asp:Label ID="Lb_cur" runat="server" Text ="%# ((GridView)Container.NamingContainer).PageIndex + 1 %"
/asp:Labelspan style="font-size: 12pt"?/ /span共 asp:Label ID="Lb_count" runat="server" text="%#((GridView)Container.NamingContainer).PageCount %"/asp:Label
?页
asp:LinkButton ID="LinkButtonFirstPage" runat="server" CommandArgument="First" CommandName="Page"
Enabled="%# ((GridView)Container.NamingContainer).PageIndex != 0 %"首页/asp:LinkButton
?
asp:LinkButton ID="LinkButtonPreviousPage" runat="server" CommandArgument="Prev" CommandName="Page"
Enabled="%# ((GridView)Container.NamingContainer).PageIndex != 0 %"上一页/asp:LinkButton
?点击跳转至第
asp:TextBox ID="Tb_page" runat="server" Width="40px" Height="15px"/asp:TextBox
?页
asp:LinkButton ID="btnGo" runat="server" causesvalidation="False"
commandargument="btnGO" commandname="Page" OnClick="btnGo_Click" text="跳转" /
?
asp:LinkButton ID="LinkButtonNextPage" runat="server" CommandArgument="Next" CommandName="Page"
Enabled="%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %"下一页/asp:LinkButton
?
asp:LinkButton ID="LinkButtonLastPage" runat="server" CommandArgument="Last" CommandName="Page"
Enabled="%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %"尾页/asp:LinkButton
/td
/tr
/table
/PagerTemplate
还要再CS代码里设置GridViewRow pagerRow = GridView1.BottomPagerRow;
System.Web.UI.WebControls.TextBox Tb = (System.Web.UI.WebControls.TextBox)pagerRow.Cells[0].FindControl("Tb_page");
int iflag = GridView1.PageIndex;
if (Session["page"]!=null)
{
Session.Remove("page");
}
Session["page"] = GridView1.PageIndex;
if (Tb.Text != "")
{
int page = Convert.ToInt32(Tb.Text);
if (page 1 || page GridView1.PageCount)
{
page = 1;
}
GridView1.PageIndex = page - 1;
}
else
{
GridView1.PageIndex = iflag;
}
ret();
ret();是绑定数据的方法
