Hi all , i am new to mvc ... currently i am working on a file uploading which should be processed with proper validations . The most important is the file size validation . i came to know that it cannot be done using javascript ... So my code goes like this .

[HttpPost]
public ActionResult FileUpload(IEnumerable<HttpPostedFileBase> UploadedFile)
{
    try
    {
        List<string> uploaderror = new List<string>();
        int cnt = 1;

        foreach (var item in UploadedFile)
        {
            if (item != null)
            {
                if (item.ContentLength > 1048576)
                {
                    string test = "lbl_error" + cnt;
                    uploaderror.Add(test);
                    cnt++;
                }
            }
        }

        ViewData["UploadError"] = uploaderror;
        //var filename = Path.GetFileName(uploadFile.FileName);
        //var filesize = uploadFile.ContentLength;
    }
    catch (Exception ex)
    {

    }
    return View();
}

And my View is

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
    <div id="Upload_Div">
        <%Html.BeginForm("FileUpload", "Home", FormMethod.Post, new { enctype="multipart/form-data" }); %>
        <ul>
            <li>
                <input type="file" id="File" name="UploadedFile"/>   <label name="lbl_error1" id="Label"></label></li>
                <br />
                <li><input type="file" id="File1" name="UploadedFile"/>  <label name="lbl_error2" id="Label1"></label></li>
                <br />
                <li><input type="file" id="File2" name="UploadedFile"/>  <label name="lbl_error3" id="Label2"></label></li>
                <br />
                <li><input type="file" id="File3" name="UploadedFile"/>  <label name="lbl_error4" id="Label3"></label></li>
                <br />
                <li><input type="submit" />
            </li>
            <li></li>
        </ul>
    </div>

My problem is how will i return to the same view and how will i use the viewdata["UploadError"] to show error message adjacent to repective upload control having file greater than 1 mb .

Thanks in advance :)

One Solution is when setting the upload error to the viewdata in the actionResult set fileUploadControl id also append with this string. for example

YourFile is more 1 mb:FileUpload id. to the viewdata. After returning the view by using javascript or jquery take the viewdata value like below

C#

function YouJsFunction(){

var test = '@ViewData["UploadError"].ToString()';
//Split error and file upload id
}

After that create div by setting the error message using jquery or javascript and append the dive to the particular fileupload control we got.

Hope this helps
