asp.net如何实现gridview控件进行分页并带有查询的代码
.aspx文件中的代码（格式你自己调）：
<asp:GridView ID="GridView1" runat="server">
</asp:GridView>
<asp:LinkButton ID="lnkbtnFrist" runat="server" OnClick="lnkbtnFrist_Click">首页</asp:LinkButton>
<asp:LinkButton ID="lnkbtnPre" runat="server" OnClick="lnkbtnPre_Click">上一页</asp:LinkButton>
<asp:Label ID="lblCurrentPage" runat="server"></asp:Label>
<asp:LinkButton ID="lnkbtnNext" runat="server" OnClick="lnkbtnNext_Click">下一页</asp:LinkButton>
<asp:LinkButton ID="lnkbtnLast" runat="server" OnClick="lnkbtnLast_Click">尾页</asp:LinkButton>
跳转到第<asp:DropDownList ID="ddlCurrentPage" runat="server" AutoPostBack="True" OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged">
</asp:DropDownList>页
.aspx.cs文件中的代码：
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
this.GridView1.PageIndex = this.ddlCurrentPage.SelectedIndex;
bind();
}
protected void lnkbtnFrist_Click(object sender, EventArgs e)
{
this.GridView1.PageIndex = 0;
bind();
}
protected void lnkbtnPre_Click(object sender, EventArgs e)
{
if (this.GridView1.PageIndex > 0)
{
this.GridView1.PageIndex = this.GridView1.PageIndex - 1;
bind();
}
}
protected void lnkbtnNext_Click(object sender, EventArgs e)
{
if (this.GridView1.PageIndex < this.GridView1.PageCount)
{
this.GridView1.PageIndex = this.GridView1.PageIndex + 1;
bind();
}
}
protected void lnkbtnLast_Click(object sender, EventArgs e)
{
this.GridView1.PageIndex = this.GridView1.PageCount;
bind();
}
public void bind()
{
GridView1.DataSource = getData();
GridView1.DataKeyNames = new string[] { "学号" };
GridView1.DataBind();
this.ddlCurrentPage.Items.Clear();
for (int i = 1; i <= this.GridView1.PageCount; i++)
{
this.ddlCurrentPage.Items.Add(i.ToString());
}
this.ddlCurrentPage.SelectedIndex = this.GridView1.PageIndex;
}
getdata()函数你能不能自己写？就是连接数据库，把查询出来的源码分时指标 源码结果放到一个DataTable对象中，然后函数返回值就是分页分页aop源码鉴别这个DataTable对象。
在asp.net怎么写上一页和下一页的源码春秋争霸源码代码
主要有几种方法，
第一种是分页分页ribbon源码原理使用第三方控件，就是源码2023算命源码所谓的“DLL”。这是分页分页别人写好了封装好了的你拿来用就可以了。
第二种"PagedDataSource"这是源码asp.net自带的分页类所有数据控件都可以使用。
第三种就是分页分页使用sql语句来分割数据。比如“select top * from table where id not in (select top id from table) order by id”
这就好像是源码你数据控件一页只显示条数据 而这个语句就是第二页的查询语句了
