现有代码:
<PagerTemplate>
当前第:
<asp:Label ID="LabelCurrentPage" runat="server" Text="<%# ((GridView)Container.NamingContainer).PageIndex + 1 %>"></asp:Label>
页/共:
<asp:Label ID="LabelPageCount" runat="server" Text="<%# ((GridView)Container.NamingContainer).PageCount %>"></asp:Label>
页
<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>
<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="30px" Text='<%# ((GridView)Container.Parent.Parent).PageIndex + 1 %>' />页
<asp:LinkButton ID="btnGo" runat="server" CausesValidation="False" CommandArgument="-2"
CommandName="go" Text="GO" />
</PagerTemplate>
后台代码:
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
BTchaxun_Click(null, null);
// 得到该控件
GridView theGrid = sender as GridView;
int newPageIndex = 0;
if (e.NewPageIndex == -2)
{
//点击了Go按钮
TextBox txtNewPageIndex = null;
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 = Convert.ToInt32(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
GridView1.DataBind();
}问题是:点了前页后页首末页都可以,但就只有那个转到多少页没用,每次都转到第一页,我调试了貌似就没有执行if (e.NewPageIndex == -2)
{
//点击了Go按钮
TextBox txtNewPageIndex = null;
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 = Convert.ToInt32(txtNewPageIndex.Text) - 1;
}
}
这句里边的代码,请高手看看哪里错了
