解决方案

作为其清晰的页面（模块）不成才的Page_Load事件，这事件prevent potbacking您的按钮。

我的意思是你尝试后回来，Page_Load事件再次运行，一切都显示为第一次，

我有这个problemt和resolveit通过将一个

 如果（！的IsPostBack）
      做一点事（）;
 

I've a simple UpdatePanel and a button outside of it. I've introduced the button as an AsyncPostBackTrigger in the UpdatePanel. UpdatePanel itself works fine but the button does not. Whenever the button is clicked, its click handler does not run just like the button is not clicked at all!

Why the button is not working and how can it be fixed?

UPDATE: here is the markup:

            <asp:UpdatePanel ID="upGridView" runat="server" UpdateMode="Conditional">
            <ContentTemplate>
                <asp:GridView ID="grdList" SkinID="SimpleGridView" DataKeyNames="Key" runat="server"
                    AllowPaging="True" PageSize="15" AutoGenerateColumns="False" Caption="<%$ Resources: CommonResources, grdListCaption %>"
                    EmptyDataText="<%$ Resources: CommonResources, grdListEmptyDataText %>" OnRowEditing="grdList_RowEditing"
                    OnPageIndexChanging="grdList_PageIndexChanging" OnRowCreated="grdList_RowCreated">
                    <Columns>

                    </Columns>
                </asp:GridView>
            </ContentTemplate>
            <Triggers>
                <asp:AsyncPostBackTrigger ControlID="btnDelete" EventName="Click" />
                <asp:AsyncPostBackTrigger ControlID="btnNew" EventName="Click" />
                <asp:AsyncPostBackTrigger ControlID="btnForward" EventName="Click" />
            </Triggers>
        </asp:UpdatePanel>

        <asp:Button ID="btnDelete" runat="server" SkinID="Button" Text="<%$ Resources: CommonResources, btnDelete %>"
            OnClick="btnDelete_Click" />
        <asp:Button ID="btnNew" runat="server" SkinID="Button" Text="<%$ Resources: CommonResources, btnNew %>"
            OnClick="btnNew_Click" />
        <asp:Button ID="btnForward" runat="server" SkinID="Button" meta:resourcekey="btnForward"
            OnClick="btnForward_Click" />

解决方案

as its clear your Page (Module) does someting in Page_Load event and this event prevent potbacking your button.

I mean You try to post back, and Page_Load event run again and everything appear as the first time,

I had this problemt and resolveit by putting a

  if(!IsPostBack)
      DoSomething();
