分页控件,大家应该都比较熟悉了。但是一直以来分页控件都给我一个很郁闷的地方,几乎都是URL传值,让人很郁闷。
如果我的是高级查询,里面的值有很多,那写死个人。同时对系统的请求也是一个考验。于是我写了这个分页控件。同时支持24种分页样式。
代码如下:
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Web.UI; using System.Web.UI.WebControls; using System.ComponentModel; using System.Web.UI.HtmlControls; namespace MyControl { [DefaultProperty("Text")] [ToolboxData("<{0}:DataPager runat=server></{0}:DataPager>")] public class DataPager : WebControl, INamingContainer, IPostBackEventHandler { public event EventHandler PagerOnclick { add { Events.AddHandler(this, value); } remove { Events.RemoveHandler(this, value); } } protected void _PagerClick(object sender, EventArgs e) { EventHandler hd = (EventHandler)base.Events[this]; if (hd != null) { hd(sender, e); } } public void RaisePostBackEvent(string Index) { //Label lbl = (Label)this.FindControl("lbl"); //lbl.Text += "自己的事件:" + Index; } void btn_Click(object sender, EventArgs e) { try { int pageIndex = int.Parse(((sender) as LinkButton).Text); this.PageIndex = pageIndex; _PagerClick(sender, e); } catch (Exception) { } } /// <summary> /// 当前页数 /// </summary> public int PageIndex { get { return int.Parse(ViewState["PageIndex"] == null ? "1" : ViewState["PageIndex"].ToString()); } set { ViewState["PageIndex"] = value; CreateChildControls(); } } /// <summary> /// 总的页数 /// </summary> public int TotalPage { get { return int.Parse(ViewState["TotalPage"] == null ? "1" : ViewState["TotalPage"].ToString()); } set { ViewState["TotalPage"] = value; } } /// <summary> /// 总的记录数 /// </summary> public int TotalRecord { get { return int.Parse(ViewState["TotalRecord"] == null ? "0" : ViewState["TotalRecord"].ToString()); } set { ViewState["TotalRecord"] = value; } } /// <summary> /// 每页数据大小 /// </summary> public int PageSize { get { return int.Parse(ViewState["PageSize"] == null ? "0" : ViewState["PageSize"].ToString()); } set { ViewState["PageSize"] = value; } } /// <summary> /// 自定义说明 /// </summary> public string CustomText { get { return ViewState["CustomText"] == null ? "" : ViewState["CustomText"].ToString(); } set { ViewState["CustomText"] = value; } } void NextPager(object send, EventArgs e) { this.PageIndex = this.PageIndex + 10 > this.TotalPage ? this.TotalPage : this.PageIndex + 10; } void PrePager(object send, EventArgs e) { this.PageIndex = this.PageIndex-10 > 1 ? this.PageIndex - 10 : 1; } void MaxPager(object send, EventArgs e) { this.PageIndex = this.TotalPage; } protected override void CreateChildControls() { this.Controls.Clear(); HtmlGenericControl div = new HtmlGenericControl(&q
