这篇文章主要为大家详细介绍了asp.net web页面自定义分页控件使用,具有一定的参考价值,感兴趣的小伙伴们可以参考一下
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!
