GridView分頁的實現(通用分頁模板)

要在GridView中加入
//實現分頁
AllowPaging="true"
//一頁數據10行
PageSize="10"
// 分頁時觸發的事件
OnPageIndexChanging="gvwDesignationName_PageIndexChanging"
在服務器事件裡
復制代碼 代碼如下:
protectedvoid gvwDesignationName_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
gvwDesignationName.PageIndex=e.newIndex;
bingDesignatioonName();
}

這裡我給出一個通用顯示分頁的模板（網上搜的，自己給出注釋)
復制代碼 代碼如下:
<PagerTemplate>
當前第:
//((GridView)Container.NamingContainer)就是為了得到當前的控件
<asp:Label ID="LabelCurrentPage" runat="server" Text="<%# ((GridView)Container.NamingContainer).PageIndex + 1 %>"></asp:Label>
頁/共:
//得到分頁頁面的總數
<asp:Label ID="LabelPageCount" runat="server" Text="<%# ((GridView)Container.NamingContainer).PageCount %>"></asp:Label>
頁
//如果該分頁是首分頁，那麼該連接就不會顯示了.同時對應了自帶識別的命令參數CommandArgument
<asp:LinkButton ID="LinkButtonFirstPage" runat="server" CommandArgument="First" CommandName="Page"
Visible='<%#((GridView)Container.NamingContainer).PageIndex != 0 %>'>首頁</asp:LinkButton>
<asp:LinkButton ID="LinkButtonPreviousPage" runat="server" CommandArgument="Prev"
CommandName="Page" Visible='<%# ((GridView)Container.NamingContainer).PageIndex != 0 %>'>上一頁</asp:LinkButton>
//如果該分頁是尾頁，那麼該連接就不會顯示了
<asp:LinkButton ID="LinkButtonNextPage" runat="server" CommandArgument="Next" CommandName="Page"
Visible='<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>'>下一頁</asp:LinkButton>
<asp:LinkButton ID="LinkButtonLastPage" runat="server" CommandArgument="Last" CommandName="Page"
Visible='<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>'>尾頁</asp:LinkButton>
轉到第
<asp:TextBox ID="txtNewPageIndex" runat="server" Width="20px" Text='<%# ((GridView)Container.Parent.Parent).PageIndex + 1 %>' />頁
//這裡將CommandArgument即使點擊該按鈕e.newIndex 值為3
<asp:LinkButton ID="btnGo" runat="server" CausesValidation="False" CommandArgument="-2"
CommandName="Page" Text="GO" />
</PagerTemplate>

對應該事件中代碼為
復制代碼 代碼如下:
protected void gvwDesignationName_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
// 得到該控件
GridView theGrid = sender as GridView;
int newPageIndex = 0;
if (e.NewPageIndex==-3)
{
//點擊了Go按鈕
TextBox txtNewPageIndex = null;
//GridView較DataGrid提供了更多的API，獲取分頁塊可以使用BottomPagerRow 或者TopPagerRow，當然還增加了HeaderRow和FooterRow
GridViewRow pagerRow = theGrid.BottomPagerRow;
if (pagerRow != null)
{
//得到text控件
txtNewPageIndex = pagerRow.FindControl("txtNewPageIndex") as TextBox;
}
if ( txtNewPageIndex!= null)
{
//得到索引
newPageIndex = int.Parse(txtNewPageIndex.Text) - 1;
}
}
else
{
//點擊了其他的按鈕
newPageIndex = e.NewPageIndex;
}
//防止新索引溢出
newPageIndex = newPageIndex < 0 ? 0 : newPageIndex;
newPageIndex = newPageIndex >= theGrid.PageCount ? theGrid.PageCount - 1 : newPageIndex;
//得到新的值
theGrid.PageIndex = newPageIndex;
//重新綁定
bingDesignatioonName();
}
