网格视图分页

Question

我有GridView，我想实现分页功能。这很好。

protected DataSet FillDataSet()
{
    string source = "Database=GridTest;Server=Localhost;Trusted_Connection=yes";
    con = new SqlConnection(source);
    cmd = new SqlCommand("proc_mygrid", con);
    ds = new DataSet();
    da = new SqlDataAdapter(cmd);
    da.Fill(ds);
    GridView1.DataSource = ds;
    GridView1.DataBind();
    return ds;


}
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
   int newPagenumber = e.NewPageIndex;
   GridView1.PageIndex = newPagenumber;
   GridView1.DataSource = FillDataSet();
   GridView1.DataBind();

}

但问题在于每个分页我都要调用FillDataSet();。有没有办法阻止它。还有其他编码方法吗？

看看Scott Mitchell的文章：Custom Paging in ASP.NET 2.0 with SQL Server 2005。

如果您使用的是2005之前版本的SQL Server，请尝试：A More Efficient Method for Paging Through Large Result Sets

Answer 2

您还可以考虑使用LINQ To SQL as it makes it easy to implement server-side pagingation。
