I have used an update panel to show latest records in gridview on click of button without the need to refresh the page.. the code is:

<asp:Button ID="Button1" runat="server" Text="Show"/>

    <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
        <ContentTemplate>
           <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataSourceID="ObjectDataSource1">

            <asp:ObjectDataSource ID="ObjectDataSource1" runat="server" OldValuesParameterFormatString="original_{0}"

                TypeName="NameSelected"

    </asp:UpdatePanel>

问题是：点击按钮，网格没有更新..任何帮助???

the problem is: on click of button, the grid is not updated.. Any help???

推荐答案

你的按钮上没有运行任何event_handler所以只有page_load和页面生命周期事件将更好地更新page_load中的数据

on your button you are not running any event_handler so only page_load and page life cycle events will occurs better to update data in page_load
