Question

在Listview中更改页面时，有什么方法可以防止重新加载整个网站？我的意思是，当我点击下一页按钮时，它再次重新加载整个网站...我可以在列表视图中转到下一页而不刷新所有内容吗？

提前致谢！

    <div class="imageset">
    <asp:ListView ID="ListView1" runat="server" DataSourceID="SqlDataSource1" DataKeyNames="ID">
        <AlternatingItemTemplate>
            <asp:ImageButton ID="ImageButton2" runat="server" ImageUrl='<%# Eval("image", "{0}") %>' PostBackUrl='<%# Eval("ID", "~/oferta.aspx?cat=" + Request.QueryString["cat"] + "&id={0}") %>' Width="180px" Height="120px" CssClass="imagebtn" CommandName="Choose" />
        </AlternatingItemTemplate>
        <ItemTemplate>
            <asp:ImageButton ID="ImageButton1" runat="server" ImageUrl='<%# Eval("image", "{0}") %>' PostBackUrl='<%# Eval("ID", "~/oferta.aspx?cat=" + Request.QueryString["cat"] + "&id={0}") %>' Width="180px" Height="120px" CssClass="imagebtn" CommandName="Choose" />

将<asp:ListView>包装在<asp:UpdatePanel>中，并将ListView的PageIndexChanged事件添加为UpdatePanel的aSyncPostBackTrigger。像这样：

<asp:UpdatePanel ID="up1" runat="server">
<ContentTemplate>
<asp:ListView `ID="listview1" runat="server" DataSourceID="SqlDataSource1">
//columns
</asp:ListView>
</ContentTemplate>
<aSyncPostBackTrigger ControlID="listview1" EventName="PageIndexChanged" />
</UpdatePanel>`
