Pass modelstate errors of Image upload to a view - asp.net

Question

I need validation for Image uploading. I have written validations using modelstate in my controller and I need to pass those validations in my view.
my view is
<div id="MemberPicture">
#using (Html.BeginForm("UpdateMemberPhotoDetails", "Member",FormMethod.Post, new { enctype = "multipart/form-data" }))
{
<b> Pictures </b>
<table>
<tr>
<td>
<img src= "#Url.Content(Model.ImagePath)" alt="Image" width="200" height="200"/>
</td>
</tr>
<tr>
<td>
<input type="file" style="width:500px;" name="imgfile" id="file" data-val="true" data-val-required="File is required" />
</td>
</tr>
<tr>
<td><input type="submit" value="Upload" class="ButtonStyleForProfiles"/></td></tr>
</table>
}
</div>
and my control code is
public ActionResult UpdateMemberPhotoDetails( HttpPostedFileBase imgfile)
{
if (ModelState.IsValid)
{
if (imgfile == null)
{
ModelState.AddModelError("File", "Please Upload Your imgfile");
}
else if (imgfile.ContentLength > 0)
{
int MaxContentLength = 1024 * 1024; //1 MB
string[] AllowedFileExtensions = new string[] { ".jpg", ".png" };
var fileExtension = imgfile.FileName.Substring(imgfile.FileName.LastIndexOf('.'));
if (!AllowedFileExtensions.Contains(fileExtension))
{
ModelState.AddModelError("File", "Please imgfile of type: " + string.Join(", ", AllowedFileExtensions));
}
else if (imgfile.ContentLength > MaxContentLength)
{
ModelState.AddModelError("File", "Your imgfile is too large, maximum allowed size is: " + MaxContentLength + " MB");
}
else
{
var folderName = UserDetailsUtil.GetMemberPhotoPathFolderName(SessionData.UserID);
var fileName = SessionData.UserID;
var path = Path.Combine(Server.MapPath("~/Content/Upload/MemberProfilePhotos/" + folderName), fileName + fileExtension);
imgfile.SaveAs(path);
ModelState.Clear();
ViewBag.Message = "Image uploaded successfully";
}
}
}
return View();
}
How can I return modelstate errors to my view. and the viewbag message should print once the image is saved. can someone help me

Answer 1

after
#using (Html.BeginForm())
{
write this line:
#Html.ValidationSummary(true)
or you can do an if statement to show an error message:
#if (!ViewData.ModelState.IsValid)
{
//show error
}
