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：

这里写图片描述

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：
