Update Progress on processing after fileupload

I have a webform with two upload controls and a number of textfields. When the button is pressed the files get uploaded and then get processed. The upload takes no time, but the processing does. I know I can't have an upload control in an update panel, so I can't work out how to use the update progress control to show my progress.

My page with an updateprogress control that does work is as follows:

    <asp:UpdatePanel ID="UpdatePanel1" runat="server">
    <ContentTemplate>
        <asp:UpdateProgress ID="UpdateProgress1" runat="server" AssociatedUpdatePanelID="UpdatePanel1" DynamicLayout="true">
            <ProgressTemplate>
                <div class="LOADING">
                    Your data is being processed<br />
                    <br />
                    <img src="/images/loading.gif" /><br />
                    <br />
                    Please wait...
                </div>
            </ProgressTemplate>
        </asp:UpdateProgress>
        <div class="addFixture">
            <asp:ValidationSummary ID="ValidationSummary1" ValidationGroup="fixture" runat="server" />
            <label>
                Type
                <asp:DropDownList ID="ddlType" runat="server" AppendDataBoundItems="true">
                    <asp:ListItem Text=""></asp:ListItem>
                </asp:DropDownList>
                <label>
                    Date
                </label>
                <asp:TextBox ID="txtDate" runat="server"></asp:TextBox>
                <label>
                    Name 1</label>
                <asp:TextBox ID="txtName1" runat="server"></asp:TextBox>
                <label>
                    Name 2
                    <asp:TextBox ID="txtName2" runat="server"></asp:TextBox>
                    <label>
                        First XML File</label>
                    <asp:FileUpload ID="firstFileUp" runat="server" />
                    <br />
                    <label>
                        Second Xml File</label>
                    <asp:FileUpload ID="secondFileUp" runat="server" />
                    <br />
                    <br />
                    <asp:Button ID="SubmitButton"  runat="server" CausesValidation="true" Text="Submit" OnClick="SubmitButton_Click" />
                    <asp:Label ID="ErrorMessageLabel" runat="server" EnableTheming="false"></asp:Label>
        </div>
    </ContentTemplate>
</asp:UpdatePanel>

I have searched for this, but people seem to be trying 开发者_如何学Pythonto get the progress of the file upload and not the processing.

Can anyone help?

Remove the UpdatePanel as all the way you can't use FileUpload controls inside it. Add to the SubmitButton OnClientClick property with following value: OnClientClick="showProgress()" Also add onto the page javascript function below:

function showProgress() {
     var updateProgress = $get("<%= UpdateProgress1.ClientID %>");
     updateProgress.style.display = "block";
}

By the way, consider to use some async file upload control like one from the Ajax Control Toolkit library

You can use an UpdatePanel and the FileUpload if you use the ASyncFileUploadControl. It works pretty well. Make sure you download the latest version because there were a couple of issues with prior releases.
