Question

我正在使用asp.net web表单，我正在使用CustomValidator与服务器端验证事件OnServerValidate来验证页面的某些内容并使用ajax AsyncFileUpload控件上传文件。

两个控件CustomValidator和AsyncFileUpload在页面上是独立的，两者之间没有关系，但当我在AsyncFileUpload中选择任何文件时，CustomValidator的服务器端验证事件会自动触发哪个造成问题。自定义验证器验证方法只应在我单击相应的提交按钮时触发，该按钮工作正常但另外CustomValidator OnServerValidate方法也会AsyncFileUpload触发文件选择。

fallowing是我为展示问题而创建的示例代码。

ASPX代码

<form id="form1" runat="server">

    <div>
        <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>

        <%-- <asp:UpdatePanel ID="upUpdateSplitedExposure" runat="server" UpdateMode="Conditional">
            <ContentTemplate>--%>
        <asp:CustomValidator ID="cvValidateSplitExposureSumByServer" Display="None"
            runat="server" ErrorMessage="" OnServerValidate="cvValidateSplitExposureSumByServer_ValidateSplitExposureSum" ControlToValidate="txttmpValidateSum" ValidateEmptyText="true"
            ValidationGroup="UpdateExposure"></asp:CustomValidator>
        <asp:TextBox runat="server" ID="txttmpValidateSum" Style="display: none; width: 0px" ValidationGroup="UpdateExposure"></asp:TextBox>
        <asp:Button ID="imgBtnUpdateSplitedExposure" runat="server" ToolTip="OK"
            Text="OK" CausesValidation="true" ValidationGroup="UpdateExposure" Enabled="true" />
        <%--   </ContentTemplate>
        </asp:UpdatePanel>--%>

        <%-- <asp:UpdatePanel ID="upUploadPayRoll" runat="server" UpdateMode="Always">
            <ContentTemplate>--%>
        <asp:AsyncFileUpload ID="asyncPayRollUploader" runat="server" CompleteBackColor="White"
            Width="400px" EnableViewState="false" />
        <asp:Button ID="ImageButton1" runat="server" ToolTip="OK"
            Text="OK" CausesValidation="true" ValidationGroup="NEWG" Enabled="true" />
        <%-- </ContentTemplate>
        </asp:UpdatePanel>--%>
    </div>
</form>

VB

Partial Class AsyncUpload
Inherits System.Web.UI.Page
Protected Sub cvValidateSplitExposureSumByServer_ValidateSplitExposureSum(source As Object, args As ServerValidateEventArgs)

    Try

        args.IsValid = False

    Catch ex As Exception

        args.IsValid = False

    End Try

End Sub

Protected Sub asyncPayRollUploader_UploadedComplete(sender As Object, e As AjaxControlToolkit.AsyncFileUploadEventArgs) Handles asyncPayRollUploader.UploadedComplete

End Sub


Protected Sub ImageButton1_Click(sender As Object, e As EventArgs) Handles ImageButton1.Click

End Sub

Protected Sub imgBtnUpdateSplitedExposure_Click(sender As Object, e As EventArgs) Handles imgBtnUpdateSplitedExposure.Click

End Sub
End Class

任何人都可以帮助我吗？
