在GridView中实现换页确认功能

首先看效果：

废话不多说，直接贴代码：

<asp:GridView ID="GridView1" runat="server" AllowPaging="true" PagerSettings-Position="Top" OnPageIndexChanging="GridView1_PageIndexChanging">
<PagerTemplate>
<asp:Label ID="lblPage" runat="server" Text='<%# "第" + (((GridView)Container.NamingContainer).PageIndex + 1) + "页/共" + (((GridView)Container.NamingContainer).PageCount) + "页" %> '></asp:Label>
<asp:LinkButton ID="lbnFirst" runat="Server" Text="首页" OnClientClick="return confirm('确定吗？');" Enabled='<%# ((GridView)Container.NamingContainer).PageIndex != 0 %>' CommandName="Page" CommandArgument="First"></asp:LinkButton>
<asp:LinkButton ID="lbnPrev" runat="server" Text="上一页" OnClientClick="return confirm('确定吗？');" Enabled='<%# ((GridView)Container.NamingContainer).PageIndex != 0 %>' CommandName="Page" CommandArgument="Prev"></asp:LinkButton>
<asp:LinkButton ID="lbnNext" runat="Server" Text="下一页" OnClientClick="return confirm('确定吗？');" Enabled='<%# ((GridView)Container.NamingContainer).PageIndex != (((GridView)Container.NamingContainer).PageCount - 1) %>' CommandName="Page" CommandArgument="Next"></asp:LinkButton>
<asp:LinkButton ID="lbnLast" runat="Server" Text="尾页" OnClientClick="return confirm('确定吗？');" Enabled='<%# ((GridView)Container.NamingContainer).PageIndex != (((GridView)Container.NamingContainer).PageCount - 1) %>' CommandName="Page" CommandArgument="Last"></asp:LinkButton>
到第<asp:DropDownList ID="PageDropDownList"
AutoPostBack="true"
OnSelectedIndexChanged="PageDropDownList_SelectedIndexChanged"
runat="server" />
页
</PagerTemplate>
</asp:GridView>

后端的两个事件:

protected void PageDropDownList_SelectedIndexChanged(Object sender, EventArgs e)
{
GridViewRow pagerRow = GridView1.BottomPagerRow;
DropDownList pageList = (DropDownList)pagerRow.Cells[0].FindControl("PageDropDownList");
GridView1.PageIndex = pageList.SelectedIndex;
}

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
GridView1.PageIndex = e.NewPageIndex;
bindData();
}
