I have a quite complex model which has an image as a part of it. While uploding the image i get the following error "The input is not a valid Base-64 string as it contains a non-base 64 character, more than two padding characters, or a non-white space character among the padding characters"
[code]....
I've tried to override error message when input incorrect data type in input field on HTML form.For example I have the model like this.
public class Person
{
public string FirstName {get;set;}
public int Age {get;set;}
}
For view, I put text input for Age to get it value.When type some string in Age text box like 'test' and press submit button.
I got this error message ,The value 'xxx' is not valid for AgeHowever, I want to change this message and try many way. There 's nothing effect this message value.

I am using ASP.NET 2.0 and trying to use a simple Form to upload a file to a web service. I have the action attrib set to the url of my web service. However, in firefox, I can't see that it is making any call to that service at all. NOTE: I can throw int the below "Action" value to a browser minus the name of the web method and get a page showing the available web method so I believe the URL for the "Action" attribute is correct.
<form id="fileUpload" action="http://localhost/AcmeABC/services/FileUploadService.asmx/ImportRates" method="post" enctype="multipart/form-data">
<input type="text" id="fileName" name="fileName" />
<asp:FileUpload runat="server" id="fileArray"/>
<input type="submit" value="Submit" />
[WebService(Namespace = [URL]/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[ToolboxItem(false)]
[ScriptService]
public class FileUploadService : System.Web.Services.WebService {
[WebMethod]
public void ImportRates(string fileName, byte[] fileArray) {
try {
MemoryStream memoryStream = new MemoryStream(fileArray);
}
catch (Exception ex) {
string error = string.Format("Error thrown for file {0} with {1} error.", fileName, ex);
}
}
How can I see what is going on since I don't see any call be made. I am also of the opinion that this might not be the best approach. I am new to the entire web development space so I am trying to find better ways of handling problems.
My testers have discovered that if you type free text into a file upload input then none of the buttons on the page work until that text is removed (so the page cannot be submitted).
I am able to replicate this with the following ASPX code (with no code behind):
<%@ Page Language="C#" AutoEventWireup="true" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<body>
<form id="form1" runat="server">
<div>
<asp:FileUpload ID="fuTest" runat="server" />
<asp:Button ID="btnSubmit" runat="server" Text="Submit" />
</div>
</form>
</body>
</html>
(Note that I haven't bound any handlers to the page; despite this, the page is submitted when the submit button is clicked only if no text is entered into the upload text box)
Is there any way to prevent users from typing free text into a file upload control? It seems that this is only possible in IE - Firefox and Chrome natively prevent text from being entered into upload input fields.
I've seen solutions elsewhere which suggest hiding input and replacing it with a label / button combo, but this seems like it might cause more problems and work inconsistently across browsers.
i want that when a user selects the file to upload then the text area of file upload control should get disabled,only the browse button should be enabled.i want to prevent the user to edit the path of the file upload control..
View 2 RepliesI am having fileupload control having its "multiple" attribute equals to "multiple". I am facing a weird issue in CHROME browser. The isse is that onchange event of file upload control is not firing for more than 12 files selected at once. The event is firing if I have 10 files selected at once.

I'm looking for a way to have user upload as many images as they want (perhaps via drag and drop) or dynamically adding more upload box.I thought statically fixing (say 6) HTML upload input box is slightly limiting and the user have to click "Browse" button (6 times in this example) and navigating to the folder to pick the file.What is the best practice to achieve this so users find it easy to use? Perhaps with some AJAX magic?I also wouldn't mind having the user click "Upload more" to reveal (say 6 more) HTML upload input box.

View 6 RepliesI have a form that when submitted shows a busy animation and disables the submit button.
Anyone know how to query Microsoft's Sys.Mvc.FormValidation to see if the form passed it's test so I can prevent the busy animation showing if the form hasn't actually been submitted? Or even some other work-around? In case it's relevant - I'm using Data Annotations for my validation.
