asp.net分頁控件PagedDataSource

在這裏總結了一個資料分頁控件PagedDataSource,首先在頁面的類庫中添加如下代碼

public static PagedDataSource Pds;

//源代碼加入以下代碼,一般放在GridView 或者是Repeater控件之後

<asp:Label ID="lblMessage" runat="server" Text="Label"></asp:Label>&nbsp;

当前第<font color="red"><asp:Label ID="lblCurrentPage" runat="server"></asp:Label></font>页<br />

<asp:Label ID="LabCountPage" runat="server" Text="Label" Visible="false"></asp:Label>

<asp:LinkButton ID="lbFirst" runat="server" OnClick="lbFirst_Click">第一页</asp:LinkButton>&nbsp;

<asp:LinkButton ID="lbPre" runat="server" OnClick="lbPre_Click">上一页</asp:LinkButton>&nbsp;

<asp:LinkButton ID="lbNext" runat="server" OnClick="lbNext_Click">下一页</asp:LinkButton>&nbsp;

<asp:LinkButton ID="lbLast" runat="server" OnClick="lbLast_Click">最后一页</asp:LinkButton><br />
