asp.net中的按钮回发未触发

Question

我在更新面板中有一个按钮。当我点击按钮时，它不会点击服务器端点击方法。不知道发生了什么。下面是给你们的代码。任何关于可能发生的事情的见解都会非常有帮助。按钮的 ID 是 btnPost。它是下方更新面板的一部分。

<asp:UpdatePanel ID="atlaspnlpost" runat="server" UpdateMode="Conditional">
            <ContentTemplate>
                <asp:Panel ID="pnlPost" runat="server" Style="width: 855px" GroupingText="Accounting use only">
                    <table class="MainSectionBody" style="width: 855px">
                        <tr style="height: 30px">
                            <td style="width: 165px">
                                <asp:Label ID="Label4" runat="server" Text="Accounting Date" Width="160px"></asp:Label>
                            </td>
                            <td style="width: 200px">

                                </td>
                        </tr>
                        <tr style="height: 30px">
                            <td style="width: 165px">
                                <asp:Label ID="lblFinanceexplanation" runat="server" Text="FinanceExpalnation" Width="160px"></asp:Label>
                            </td>
                            <td style="width: 200px">
                                <asp:TextBox ID="txtFinanceExplanation" runat="server" Width="200px"  TabIndex="99"

                            </td>
                            <td style="width: 85px">
                                <td style="width: 405px">
                                   <asp:Button ID="btnPost" runat="server" Text="Post" Width="76px" TabIndex="15" />
                                </td>
                        </tr>
                    </table>
                </asp:Panel>
            </ContentTemplate>
            <Triggers>
                <asp:AsyncPostBackTrigger ControlID="btnSearch" EventName="Click" />
                <asp:AsyncPostBackTrigger ControlID="btnRefresh" EventName="Click" />
                 <asp:AsyncPostBackTrigger ControlID="ddlYear" EventName="SelectedIndexChanged" />

            </Triggers>
        </asp:UpdatePanel>

下面是按钮后退事件：-

Protected Sub btnPost_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnPost.Click
            Dim sErrMsg As String = String.Empty
            If CStr(Session(Common.Session.UserName)) = String.Empty Then
                Response.Redirect("~/ErrorInfo.aspx?mes=Your session has expired. Please search the deal again", False)
            Else
                If Not ValidatePost(sErrMsg) Then
                    Me.DispMessage(sErrMsg)
                Else
                    Try
                        If ValidateandSaveGrid() = True Then
                            SaveHoldBackAloc()
                            SaveEmpAlloc()
                            SavePaymentLog()
                            ConfigureAfterPost()
                            getHoldbackHistory()
                        Else
                            Me.DispMessage("Invalid Data")
                        End If

                    Catch ex As Exception
                    End Try
                End If
            End If
        End Sub

你看到为你的按钮添加了一个属性

OnClick="btnPost_Click"

应该是这样的：

<asp:Button ID="btnPost" runat="server" Text="Post" OnClick="btnPost_Click" Width="76px" TabIndex="15" />
