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：
