asp.net web页面自定义分页控件使用详解

这几天学习了一下自定义分页控件，现将实现方法记录下来，亲测可以实现：

1.首先创建一个.ascx文件，命名为turnpage，然后在里面写控件前台展示的界面：

2.然后在turnpage.ascx.cs里面写相应的后台代码，代码如下：

namespace web
{
public delegate void gotopage(int pagenum);

public partial class turnpage : system.web.ui.usercontrol
{
  private gotopage _gotopage = null;

  protected void page_load(object sender, eventargs e)
  {

  }

  public void initcontrol(gotopage gp)
  {
    _gotopage = gp;
  }


  public int datacount
  {
    get { return int32.parse(lbl_totalcount.text); }
    set { lbl_totalcount.text = value.tostring(); }
  }

  public int currpagenum
  {
    get { return int32.parse(lbl_currpage.text); }
    set { lbl_currpage.text = value.tostring(); }
  }

  public int totalpagenum
  {
    get { return int32.parse(lbl_totalpage.text); }
    set { lbl_totalpage.text = value.tostring(); }
  }

  public int pagesize
  {
    get { return int32.parse(ddl_pagesize.selectedvalue); }
  }

  protected void btn_fristpage_click(object sender, eventargs e)
  {
    _gotopage(1);
  }

  protected void btn_prevpage_click(object sender, eventargs e)
  {
    if (int.parse(lbl_currpage.text) > 1)
      _gotopage(int.parse(lbl_currpage.text) - 1);
    else
      _gotopage(1);
  }

  protected void btn_nextpage_click(object sender, eventargs e)
  {
    if (int.parse(lbl_currpage.text) < int.parse(lbl_totalpage.text))
      _gotopage(int.parse(lbl_currpage.text) + 1);
    else
      _gotopage(int.parse(lbl_totalpage.text));
  }

  protected void btn_lastpage_click(object sender, eventargs e)
  {
    _gotopage(int.parse(lbl_totalpage.text));
  }

  public void controlbuttonclick()
  {
    if (datacount > 0)
    {
      btn_fristpage.enabled = true;
      btn_prevpage.enabled = true;
      btn_lastpage.enabled = true;
      btn_nextpage.enabled = true;
    }
    else
    {
      btn_fristpage.enabled = false;
      btn_prevpage.enabled = false;
      btn_lastpage.enabled = false;
      btn_nextpage.enabled = false;
    }



    if (currpagenum == 1)
    {
      btn_fristpage.enabled = false;
      btn_prevpage.enabled = false;
    }

    if (currpagenum == totalpagenum)
    {
      btn_lastpage.enabled = false;
      btn_nextpage.enabled = false;
    }

    if (currpagenum == 0)
    {
      btn_fristpage.enabled = false;
      btn_prevpage.enabled = false;
      btn_lastpage.enabled = false;
      btn_nextpage.enabled = false;
    }
  }

  protected void ddl_pagesize_selectedindexchanged(object sender, eventargs e)
  {
    _gotopage(1);
  }

  protected void btn_go_click(object sender, eventargs e)
  {
    int pagenum;
    if (int.tryparse(txt_pagenum.text, out pagenum))
    {
      if (pagenum > totalpagenum)
        _gotopage(totalpagenum);
      else if (pagenum < 1)
        _gotopage(1);
      else
        _gotopage(pagenum);
    }

  }
}}

3.控件的方法就写好了，现在要做的就是在其它页面引用这个控件了，引用方法如下：

然后在页尾还需配置一下：

4.这就是最后一步了，在你引用这个控件的页面的后台代码里写下以下语句：

大功告成了！
