ASP.NET中自定义DataGrid分页设置的实现

先定义ASPX页面，注意AllowCustomPaging要设为"False"：

＜asp:datagrid id="MyDataGrid" runat="server" Width="100%" PageSize="20" AllowPaging="True" AutoGenerateColumns="False" DataKeyField="FDictid"＞

＜Columns＞ ＜/Columns＞   ＜PagerStyle Visible="False"＞＜/PagerStyle＞   ＜/asp:datagrid＞

 

  ＜asp:linkbutton id="btnFirst" runat="server" CommandArgument="fist"＞首页＜/asp:linkbutton＞     ＜asp:linkbutton id="btnPrev" runat="server" Width="36px" CommandArgument="prev"＞上一页＜/asp:linkbutton＞     ＜asp:linkbutton id="btnNext" runat="server" CommandArgument="next"＞下一页＜/asp:linkbutton＞     ＜asp:linkbutton id="btnLast" runat="server" CommandArgument="last"＞末页＜/asp:linkbutton＞     ＜asp:label id="lblCurrentIndex" runat="server"＞＜/asp:label＞/＜asp:label id="lblPageCount" runat="server"＞＜/asp:label＞     跳转到＜asp:TextBox id="txtGoPage" runat="server" Width="30px" CssClass="textbox"＞＜/asp:TextBox＞   ＜asp:Button id="btnGo" runat="server" Text="GO" CssClass="button" Width="29px"＞＜/asp:Button＞

 

CODE:

 

public void BindGrid()   {   string strSql ="SELECT * FROM t_dict ";   SqlDataAdapter myCommand = new SqlDataAdapter(strSql, myConnection);   DataSet ds = new DataSet();   myCommand.Fill(ds, "t_dict");   MyDataGrid.DataSource=ds.Tables["t_dict"].DefaultView;   MyDataGrid.DataBind();   ShowStatsPage();   }

private void PagerButtonClick(object sender, System.EventArgs e)   {   //获得LinkButton的参数值   String arg = ((LinkButton)sender).CommandArgument;      switch(arg)   {   case ("next"):   if (MyDataGrid.CurrentPageIndex ＜ (MyDataGrid.PageCount - 1))   MyDataGrid.CurrentPageIndex ++;   break;   case ("prev"):   if (MyDataGrid.CurrentPageIndex ＞ 0)   MyDataGrid.CurrentPageIndex --;   break;   case ("fist"):   MyDataGrid.CurrentPageIndex=0;   break;   case ("last"):   MyDataGrid.CurrentPageIndex = (MyDataGrid.PageCount - 1);   break;   default:   //本页值   MyDataGrid.CurrentPageIndex = Convert.ToInt32(arg);   break;   }   BindGrid();   }      void ShowStatsPage()   {   //显示页面信息   lblCurrentIndex.Text = "[＜font color="blue"＞当前为第：" + ((int)MyDataGrid.CurrentPageIndex+1) + "页＜/font＞]";   lblPageCount.Text = "[＜font color="blue"＞共：" + MyDataGrid.PageCount + "页＜/font＞]";   }            private void MyDataGrid_PageIndExchanged(object source, System.Web.UI.WebControls.DataGridPageChangedEventArgs e)   {   //处理按下数字的方法   MyDataGrid.CurrentPageIndex = e.NewPageIndex;   BindGrid();   }         private void btnGo_Click(object sender, System.EventArgs e)   {   //页面直接跳转的代码   if(txtGoPage.Text.Trim()!="")   {   int PageI=Int32.Parse(txtGoPage.Text.Trim())-1;   if (PageI ＞=0 && PageI ＜ (MyDataGrid.PageCount))   MyDataGrid.CurrentPageIndex = PageI ;   }   BindGrid();   }   //----------------------翻页代码结束
