ASP.NetPager is a commonly used pagination control to implement data pagination on ASP.NET web pages. Here are the general steps for using the ASP.NetPager pagination control:

  1. Add the ASP.NetPager control to an ASP.NET webpage.
<asp:AspNetPager ID="AspNetPager1" runat="server" OnPageChanged="AspNetPager1_PageChanged"></asp:AspNetPager>
  1. Bind data to controls in the code file.
protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        BindData();
    }
}

private void BindData()
{
    // 绑定数据到控件
    AspNetPager1.RecordCount = TotalRecordCount; // 设置总记录数
    AspNetPager1.PageSize = PageSize; // 设置每页显示的记录数

    // 查询当前页的数据
    var data = GetData(AspNetPager1.CurrentPageIndex, PageSize);

    // 绑定数据到GridView或其他控件
    GridView1.DataSource = data;
    GridView1.DataBind();
}
  1. Handle pagination events of the pagination control.
protected void AspNetPager1_PageChanged(object sender, EventArgs e)
{
    BindData(); // 重新绑定数据
}
  1. Handle the query logic for each page’s data as needed.
private List<DataItem> GetData(int pageIndex, int pageSize)
{
    // 根据pageIndex和pageSize查询数据库或其他数据源获取数据
    // 返回一个包含当前页数据的List<DataItem>对象
}

The above are the basic steps of using ASP.NetPager pagination control, which can be adjusted and expanded according to actual needs.
