My MVC 2 app includes a simple file upload within in a strongly typed view and I am trying to figure out how to apply model validation to the file name. Is this possible? Is there better way to do file upload within an MVC app?
The salient parts of the (prototype) controller code are:

The Create view code was generated with VS2010 and then modified to support file upload and client side validation:

i am using Asyncfile upload in model pop up . i want to clode the modelpopup after the file uploaded.
View 7 RepliesI am working with ASP. net MVC project. There is File upload functionality to be implemented in the project. I am able to show the upload control using input-file. But I am not able to show defalut value (file with path) in text area using model binding.
Can we bind model to file upload control in MVC so that we can show Previous file (already uploaded) in the text area.
what I have in view is this
<input type="file" name="fileupload1" id="fileupload1" />
can we write something like this
<input type="file" name="fileupload1" id="fileupload1" value=Model.Object.FileName/>
will it show the previous file name and will the model get bind?
I have a form which uploads a photo to my database, and I use a view model to aid in this process.
View Model:
public class GalleryViewModel
{
//Members:
public Gallery _photo { get; set; }
public string _title { get; set; }[code]...
When I debug the code, I see that the in the post method in my controller, all the information from the form is updated in the view model except for the uploadFile which is null.In the form I use enctype = "multipart/form-data". When I use my master page the uploadFile is null but when I use the default MVC master page everything works fine.
Here is my master page:
<%@ Master Language="C#" MasterPageFile="~/views/Shared/GeneralMaster.master" Inherits="System.Web.Mvc.ViewMasterPage" %> [code]....
I like how the "Html.ValidationMessageFor" and "Html.ValidationSummary" helpers work for validating textboxes, such as for required fields. Is there some way I can accomplish the same thing for a file input control? From the examples I've seen so far you cannot directly bind a file upload to your model, so I can't use the [Required] attribute that I am using for the textboxes.
View 10 RepliesIm trying to upload file (lets say .xls file) but i need to check if the file type is macth with it binary. for example we can renamefileA.mp3 as fileA.xls on our windows and upload it. i need to check this first. can anyone suggest me how to check this file type ?based from what I browse, I found that BInaryReading can do it. here is the code
[Code]....
this check correctly. BUT, once it returns TRUE (when FileA.xls is really an XLS file), the POSTED FILE content will be 0. and the upload went file (the SAVEAS works) , and the file copied to the specified directory. but the content is 0 and when i open it, it said that the file is corrupted.i think this is due to the BINARY READER. is that true ? because before above method called, i make a breakpoint and the POSTEDFILE content length is still 16kb. after the method called, its 0.
I have a fileUpload User Control FileUploadControl.ascx containing asp.net fileupload control and a requiredfield validator.I have another usercontrol RenderingTemplate.ascx that contains two FileUploadControl.ascx.RenderingTemplate.ascx is on page RenderingTemplateDetails.aspx, this page has save and cancel button.Now My requirement is in case user selects a file in one fileupload control,he has to select in other as well. If he does not select any file,let postback happen. cannot use Requiredfieldvalidator as it fires for both. I tried adding onclientclick to page save button and check whether file upload has some text in it.but i didnot succedd.Now i want this functionality to be a part of control so that i dont have to recode it on every page. IS there any clientside event on usercontrol which fires when save button of page is clicked.
View 1 RepliesI have an application that lets the use upload a pdf, I wanted to put a limit on the size the pdf can be. If the user tried to upload something too big I wanted to display a message to the user. I am trying to use a custom validator where it checks the size of the file and if it is too big it will set the "IsValid" to false. Is this the correct way to go about doing this? Is there a better way? When I test it, everything works in IE 8 and FF, but it does not work in IE 7 and can't figure out why.Here is what I have so far, this is on my aspx page:

And this is the code behind:

Is it possible, inside a Custom Model Binder, to fire "something" that "says" the value is invalid so it gets handled by validation part?
Basically, I am getting an exception when the value for the property is invalid.
I was referring muddasar's one of the article for the validation. Below is my code and i am trying to validate the file upload selected file format on the submit button. I have 4 upload control and fu1 is mandatory field and others are not mandatory fields. Though i need to validate all the four uploads if the files have been selected. My full sample code is below for easy testing,
<asp:FileUpload runat="server" ID="fu1" />
<asp:Label ID="lblMessage1" runat="server"></asp:Label>
<asp:FileUpload runat="server" ID="fu2" />
<asp:Label ID="lblMessage2" runat="server"></asp:Label>

I am doing slight mistake on the return to the main function. if i test indvidual function it works fine. whereas if i include the 4 functions in one function with the return statement, it's not validating. goes to to the server.

View 4 RepliesI am using the async file upload control to upload to a image file. I want the user to upload only jpg files. And for that I am checking the uploadedfile content type in server side, after the upload complets. I wanna check this, before upload starts. There is one javascript method
function startUpload(sender, args){}

I have recently started working on ASP.NET with MVC 2 framework, and I am facing following difficulty in validating my data,
Scenario:
In my application the view (ASPX) is divided into tabs (jQuery) and each tab's content is ViewUserControl (ASCX). The main model for the view has collection of sub models for individual tabs. I use RenderPartial method to render view user control.
[Code]....
And the user control (Tab1.ascx) refers the specific model for it,
[Code]....
Now if in my Tab1Model if I put following validation
[Code]....
In the controller ModelState.IsValid is always indicates TRUE. How do I override the validation behavior such that it as well looks the items in the collection member (which holds sub models) as well.
<%= Html.ValidationMessage("FirstName") %>

View 1 RepliesI want to upload files to the web servers from the client machines.
Can i upload a file on a network share folder using file upload control?
I would like to create a share folder on a file server sitting next to the web server. If i upload the file from the network share folder instead of uploading it from the client machine does it make any difference?
Will the file be stored in a temporary location before copying to the final destination? Where will be the file stored in this case of uploading it from share folder?
I am using the File Uploader to upload files. It is working fine. But I receive the page can not be displayed when I try to upload a file>4Mb in size.

I have a viewmodel with a property of a model class type. I set some properties in the model class to be able to show it to the user but then when I make a post, the model gets validated. How to overcome this? I don't want to enforce the DataAnnotations contraint in this case....

TheModel TheModel { get; set;}

I use viewModels to communicate between my controller and my view. To get model validation, i use a partial class like this :

I have a Order view with 2 user controls in it.
The first user control in the view is just to validate the customer and get some more details about the customer. This control is having one text box (customer name) with the button. When the user clicks the button it should validate the customer name in the client side using data annotations of customer model. if validation success then it should use some bussiness logic to verify the customer and show the customer details on the form.
The 2nd user control in the view is to get the address of the customer by searching for the house no and the postcode. This control is having 2 text box with the button.
The first user control is based on the strongly typed customer entity
The 2nd user control is bsed on the strongly typed address entity
The view with both the user control is based on the strongly typed order entity.
The issue here is with the validation. I have the validation summary in the view and client sider validation is enabled. When i click the search button on the first user control the client validation starts and throws validation error messages because when i search for the customer at that point of time i will not have values to may of the customer related fields in the order view.
The same thing happen when i click the search button on the 2nd view. It will throw client side validation for other fields.
What i want to achive is that when the user click the search button on the user control 1 then the validation should happen only to the customer name field (both in client and server).
When the user click the search button on the 2 nd user control the the validation should happen only for houseno and the postcode both in client and the server.
When the user clicks the save button on the order view all the fields in the form even the controls usere input fields should get validated. How to achive this in mvc?
With my model, I have one view model using another as its base. In my case, BaseUserModel is inherited by CreateUserModel, in order to share common properties such as Username and Password. My CreateUserModel adds to that by having ConfirmPassword, Email, SecurityQuestion, etc.
My problem is, when using the ValidationSummary() Html helper, the validation is obviously in order of the properties in my model. Basically, because of the inheritance I have going on here, the errors are not in the correct order.
Is it possible to control when or how these validation rules are added to the list? The only attribute I'm using is Required.
I make use of validation with data annotations in my model classes. How do I make sure this annotations are not violated when I validate data in my business layer, before sending it to the DAL? I guess I don't want to define the validation rules in two places (model classes and in my BLL-classes)?
