Adding the backend of a web control to the control itself?

530 views Asked by Alex At 09 December 2013 at 15:02

Currently I have a web control and backend code for this control (as well as a designer etc).

To upload it as a macro to Umbraco though I need to condense this all into one file. How would I go about this without breaking something? Currently when I copy paste the code in with tags all the else and if's break.

web form

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="UploadFileControl.ascx.cs" Inherits="FileUpload.UploadFileControl" %>

    <form id="UploadForm" runat="server">
<asp:FileUpload id="FileUploadControl" runat="server" />
    <asp:Button runat="server" id="UploadButton" text="Upload" onclick="UploadButton_Click" />
    <br /><br />
    <asp:Label runat="server" id="StatusLabel" text="Upload status: " />
</form>

And the user control backend

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;


namespace FileUpload
{
    //this backend for the web control will be used to upload a file that will have it's XML tags pulled and displayed on a page. 
    //this code checks if the fileupload control has input inside it, then proceeds to the next page with the document saved.
    public partial class UploadFileControl : System.Web.UI.UserControl
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }
        //names the script manager which will be used when the user attempts to upload a form / gives an error if they incorrectly attempt to upload
        protected void UploadButton_Click(object sender, EventArgs e)
        {
            //if file is located
            if (FileUploadControl.HasFile)
            {
                try
                {
                    //allow content type of document / docx
                    if (FileUploadControl.PostedFile.ContentType == "document/docx")
                    {
                        //if the file is is less than 51mb
                        if (FileUploadControl.PostedFile.ContentLength < 2000)
                        {
                            //name the filename, find the path of the name
                            string filename = Path.GetFileName(FileUploadControl.FileName);
                            //path of server upload (we just need to save it as a variable to be found on the next page, as it will be made / deleted
                            FileUploadControl.SaveAs(Server.MapPath("~/") + filename);
                            //update the label with file uploaded
                            StatusLabel.Text = "Upload status: File uploaded!";
                        }
                        else
                            //display the size the file needs to be less than
                            StatusLabel.Text = "Upload status: The file has to be less than 2mb!";
                    }
                    else
                        //tell the user only docx files are accepted
                        StatusLabel.Text = "Upload status: Only DOCX files are accepted!";
                }
                catch (Exception ex)
                {
                    //display the exception message, in which case it would be either size / type / if it's present
                    StatusLabel.Text = "Upload status: The file could not be uploaded. The following error occured: " + ex.Message;
                }
            }
        }
    }
}

One possibility is to move your codebehind content to the page itself, using <script runat="server"> tags. Like this:

SamplePage.aspx

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="SamplePage.aspx.cs" Inherits="Test.SamplePage" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>

    </div>
    </form>
</body>
</html>

SamplePage.aspx.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace Test
{
    public partial class SamplePage : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            //Sample code.
        }
    }
}

Would translate into this:

SamplePage.aspx

<%@ Import Namespace="System.Web"%>
<%@ Import Namespace="System.Web.UI"%>
<%@ Import Namespace="System.Web.UI.WebControls"%>
<%@ Page Language="C#" %>

<script runat="server">
    protected void Page_Load(object sender, EventArgs e)
    {
        //Sample code.
    }
</script>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
        <div>
        </div>
    </form>
</body>
</html>

You may try and check if it works with .ascx content as well.
