GridView分页的实现(通用分页模板)

protectedvoid gvwDesignationName_PageIndexChanging(object sender, GridViewPageEventArgs e)

{

gvwDesignationName.PageIndex=e.newIndex;

bingDesignatioonName();

}

<PagerTemplate>

当前第:

//((GridView)Container.NamingContainer)就是为了得到当前的控件

<asp:Label ID="LabelCurrentPage" runat="server" Text="<%# ((GridView)Container.NamingContainer).PageIndex + 1 %>"></asp:Label>

页/共:

//得到分页页面的总数

<asp:Label ID="LabelPageCount" runat="server" Text="<%# ((GridView)Container.NamingContainer).PageCount %>"></asp:Label>

页

//如果该分页是首分页，那么该连接就不会显示了.同时对应了自带识别的命令参数CommandArgument

<asp:LinkButton ID="LinkButtonFirstPage" runat="server" CommandArgument="First" CommandName="Page"

Visible='<%#((GridView)Container.NamingContainer).PageIndex != 0 %>'>首页</asp:LinkButton>

<asp:LinkButton ID="LinkButtonPreviousPage" runat="server" CommandArgument="Prev"

CommandName="Page" Visible='<%# ((GridView)Container.NamingContainer).PageIndex != 0 %>'>上一页</asp:LinkButton>

//如果该分页是尾页，那么该连接就不会显示了

<asp:LinkButton ID="LinkButtonNextPage" runat="server" CommandArgument="Next" CommandName="Page"

Visible='<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>'>下一页</asp:LinkButton>

<asp:LinkButton ID="LinkButtonLastPage" runat="server" CommandArgument="Last" CommandName="Page"

Visible='<%# ((GridView)Container.NamingContainer).PageIndex != ((GridView)Container.NamingContainer).PageCount - 1 %>'>尾页</asp:LinkButton>

转到第

<asp:TextBox ID="txtNewPageIndex" runat="server" Width="20px" Text='<%# ((GridView)Container.Parent.Parent).PageIndex + 1 %>' />页

//这里将CommandArgument即使点击该按钮e.newIndex 值为3

<asp:LinkButton ID="btnGo" runat="server" CausesValidation="False" CommandArgument="-2"

CommandName="Page" Text="GO" />

</PagerTemplate>

protected void gvwDesignationName_PageIndexChanging(object sender, GridViewPageEventArgs e)

{

// 得到该控件

GridView theGrid = sender as GridView;

int newPageIndex = 0;

if (e.NewPageIndex==-3)

{

//点击了Go按钮

TextBox txtNewPageIndex = null;

//GridView较DataGrid提供了更多的API，获取分页块可以使用BottomPagerRow 或者TopPagerRow，当然还增加了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

{

//点击了其他的按钮

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;

//重新绑定

bingDesignatioonName();
