推荐答案

如果你的问题是关于gridview分页，那么将允许分页属性设置为true。你将自动获得next和prev按钮并在pageindexchanging事件中显示功能，或者如果你想使用外部按钮继续分页功能，那么下面给出的例子是这样的。

if ur question is regarding gridview paging then set the allowing paging property as true. u will get next and prev button automatically and wirte the functionality in "pageindexchanging event" or if u want to continue the paging functionality using outside buttons then here is the example given below.

public partial class _Default : System.Web.UI.Page
{
static SqlConnection cn = new SqlConnection("server=DEVAPP;user id=sa;password=sa123;database=test");
protected void Page_Load(object sender, EventArgs e)
{
getdata();
}
public void getdata()
{
SqlDataAdapter da = new SqlDataAdapter("select * from employee", cn);
DataSet ds = new DataSet();
da.Fill(ds, "emp");
GridView1.DataSource = ds;
GridView1.DataBind();
}
protected void prev_Click(object sender, EventArgs e)
{
if (GridView1.PageIndex > 0)
{
GridView1.PageIndex = GridView1.PageIndex - 1;
getdata();
}
}
protected void next_Click(object sender, EventArgs e)
{
GridView1.PageIndex = GridView1.PageIndex + 1;
getdata();
}
}

您必须触发查询才能返回结果以及行号列。为此使用SQL Server的Row_Number（）函数。移动到所选记录的详细信息页面时，也传递行号（客户端或服务器端）。单击下一个或上一个按钮，您可以运行用于绑定gridview的相同查询，并根据您可以显示所选记录的行号。

You will have to fire a query to return the result plus a column for row number. Use Row_Number() function of SQL Server for this. When moving to the details page for the selected record, pass the row number also (client side or server side). on click of next or previous buttons, you can run the same query that you used to bind the gridview and based on the row number you can show the selected record.
