这里我实现了DataGrid的个性化分页，现在把代码贴出来朋友们参考，同时在这个功能的实现过程，参考了“飞刀”从国外翻译的一篇文章。
先定义ASPX页面，注意AllowCustomPaging要设为"False"：
＜body＞
＜form id="DictList" method="post"
runat="server"＞
＜TABLE style="BORDER-COLLAPSE: collapse"
cellSpacing="0" width="100%" border="1"＞
＜TR＞
＜td
bgColor="#c0c000"＞信息：＜FONT face="Arial"
color="#ffffff"＞数据维护＜/FONT＞
＜/td＞
＜/TR＞
＜tr＞
＜td＞＜FONT
face="宋体"＞＜/FONT＞＜/td＞
＜/tr＞
＜tr＞
＜td＞＜asp:datagrid
id="MyDataGrid" runat="server" Width="100%" PageSize="20"
AllowPaging="True" AutoGenerateColumns="False"
DataKeyField="FDictid"＞
＜SelectedItemStyle
BackColor="#FFC080"＞＜/SelectedItemStyle＞
＜HeaderStyle
BackColor="#C0C000"＞＜/HeaderStyle＞
＜Columns＞
＜asp:ButtonColumn
Text="选择" HeaderText="选择" CommandName="Select"＞
＜HeaderStyle
Font-Bold="True" HorizontalAlign="Center"
Width="8%"＞＜/HeaderStyle＞
＜ItemStyle Font-Bold="True"
HorizontalAlign="Center"＞＜/ItemStyle＞
＜/asp:ButtonColumn＞
＜asp:BoundColumn
DataField="FDictID" SortExpression="FDictID asc"
HeaderText="标识号"＞
＜HeaderStyle
Width="15%"＞＜/HeaderStyle＞
＜/asp:BoundColumn＞
＜asp:BoundColumn
DataField="FNameCn" SortExpression="FNameCn asc"
HeaderText="名称"＞
＜HeaderStyle
Width="15%"＞＜/HeaderStyle＞
＜/asp:BoundColumn＞
＜asp:BoundColumn
DataField="FNameEn" SortExpression="FNameEn asc"
HeaderText="英文名称"＞
＜HeaderStyle
Width="15%"＞＜/HeaderStyle＞
＜/asp:BoundColumn＞
＜asp:BoundColumn
DataField="FNote" SortExpression="FNote asc"
HeaderText="描叙"＞
＜HeaderStyle
Width="47%"＞＜/HeaderStyle＞
＜/asp:BoundColumn＞
＜/Columns＞
＜PagerStyle
Visible="False"＞＜/PagerStyle＞
＜/asp:datagrid＞＜/td＞
＜/tr＞
＜/TABLE＞
＜TABLE
style="BORDER-COLLAPSE: collapse" cellSpacing="0" width="100%"
bgColor="#ff9966" border="1"＞
＜TR＞
＜td align="right"＞＜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＞＜/td＞
＜/TR＞
＜/TABLE＞
＜/form＞
codebehind主要功能部分代码：
private
void Page_Load(object sender, System.EventArgs e)
{
//
在此处放置用户代码以初始化页面
myConnection = new
SqlConnection(System.Configuration.ConfigurationSettings.AppSettings["ConnString"]);
if (!IsPostBack)
BindGrid();
}
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
