C# - Success Messages As Opposed To Model State Error Messages?

Jan 26, 2010

For error messages, validation faults etc you have


But, where do you put success responses like "You successfully transfered alot of money to your ex." + "Your balance is now zero". I still want to set it at the controller level and preferably in key-value way, the same way as errormessages but without invalidating the modelstate.

Valid User Session Variable Not Found - Two Identical Error Messages

Apr 8, 2016

I am getting two identical errors message when I view my Web page in my browser:

Valid User Session Variable Not Found: System.NullReferenceException for this line:

Response.Write(Session("ValidUser").ToString & "<br />") <----------

and the same error for this line:

Response.Write(Session("strEmail").ToString) <-----------

This is the code in that page:

Protected Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load
Response.Write(Session("ValidUser").ToString & "<br />")
Catch ex As System.Exception
Response.Write("Valid User Session Variable Not Found: " & ex.ToString & "<br />")
End Try

[Code] .....

This the page that users are redirected to after logging on and, after verifying their credentials at the log-on stage, should show 'Hello, Welcome to my website'.

Do these errors mean that the user cannot be validated in the database?

How To Hide / Show CustomValidation Messages Without Postback

Jan 27, 2010

UPDATE : Figured it out..

The objects I was passing to the ValidatorHookupControl were'nt being set properly (were null). Now that they are, the messages are currectly dissapearing when the hooked up control looses it's focus.

I have some ClientValidation controls that have ClientSideValidation methods which work fine when validating the page..

However, how can I make it so that when a certain control that a CustomValidators clientside method kicks in and udates the validation message depending on whether the validation has passed or not. (Like the RequiredFieldValidator or RegExValidator).

My Customvalidators do not have their ControltoValidate properties set as some of them depend on multiple controls.

I don't want any postbacks (full or partial).

I have tried..

1) Adding an onchange attribute on dropdowns, radioboxes and checkboxes that call a helper clientside method which calls Page_ClientValidate('GroupName'), then setting window.location back to the control in question (as it went back to top of screen).

Using this method the args.IsValid is still being set by the ClientSideValidation method.

2) And I have tried ValidatorHookupControl (control, validator) but that doesn't seem to work either.

VS 2005 - Show Processing Messages From Code Behind

Sep 15, 2011

I have a GridView where user can select multiple jobs to be processed. When user hits the 'Run" button, selected jobs are being processed, at this point I would like to show a message as the application steps through each job, like "Now Processing ABC", "Now processing DEF" etc

Is there an easy way to do this (from code behind). Could I force a postback and have a label / text box being displayed with different messages ???

Passing Messages To The User In MVC2?

Jun 29, 2010

I am using ASP.NET MVC2 for my project. I want to send the user confirmation messages after actions.

Ideally: User clicks on a link with a query string (i.e. a link to delete an entry) The controller does what the link says, creates the success message, and uses RedirectToAction to get rid of the query string from the URL. The new action displays the success message.

Validation - Pass Error Messages

Feb 3, 2010

This is probably going to end up as a stupid question, but countless research has offered me no results. I know there are different types of errors I want to check for, and when I should be throwing an exception for "exceptional" errors, and that I should create validating functions for input and other checks. My problem is, how do I send an error back to a page when the data entered fails in a separate class?

For Example:

User input entered in Page1.aspx, click calls Submit() in Class.vb Class.vb finds that input is invalid How do I update Page1.aspx label to say "Hey, that is not right".

Bifurcating Validation Error Messages In .Net?

Jan 14, 2010

In ASP.Net, how do I limit validation messages to only one?

Rule: User must put in a number between 0 and 1000.

Current [undesired] Behavior:

User types 1001: validator says "Please put in a non-negative number beneath 1000"
User types -1: validator says "Please put in a non-negative number beneath 1000"

Desired Behavior:

User types 1001: validator says "Please put in a number beneath 1000"
User types -1: validator says "Please put in a non-negative number"

In other words, how can I use two asp:RangeValidators whose disallowed values intersect but only turn on the desired one? I do not want to handle a ServerValidate event on the server.

C# - Best Practices When Reporting Exception Messages To The User

Mar 4, 2011

In my ASP.NET MVC application, I do not want to report all exception messages to the user. But there are certain types of exceptions that I'd like to report to the user, so I created an action filter to decide if it's this particular type of exception, and if so then display the exception's message, otherwise display a generic message. So I created a custom exception called ClientException.

My filter looks something like this:

if (filterContext.Exception is ClientException)
message = filterContext.Exception.Message.Replace("
", " ").Replace("
", " ");
message = "An error occured while attemting to perform the last action. Sorry for the inconvenience.";

filterContext.HttpContext.Response.Status = "500 " + message;

I read this where the author recommends using existing .NET exception types to report usage errors. However, by introducing my custom exception, I just have to do a single check in my filter.

Web Forms :: Validation Error Messages Not Being Removed

Aug 5, 2010

I have a form that has contact fields, billing address, and shipping address. So if i fill out my contact information ONLY and left billing and shipping address blank then hit submit, the validation for the billing address and shipping address appears. Ok no problem, there is a check in each billing and shipping fields that once click on it copies the address from contact to billing or shipping fields. Everything works except for the validation messages. They are still there. Is there a way to remove the validation message after the textboxes are populated with data?

Visual Studio :: Javascript Error Messages?

Mar 16, 2011

I'm running Visual Studio 2010 and IE9 and integrating with facebook and the facebook javascript code keeps resulting in exceptions... 'Error: '__flash__removeCallback' is undefined' which I can't do anything about.

Visual Studio keeps on telling me about each and every one of these exceptions every time I load the webpage that I'm working on which makes doing anything else difficult. I managed to switch off this behavior by enabling Silverlight debugging because apparently the debugger can only work with one of the other.

But now the browser keeps telling me about the same exceptions even though I've disabled script debugging and have de-selected 'Display a notification about every error'.

So how do I stop Visual Studio from telling me about numerous Javascript exceptions that I can't do anything about? Why can one not just configure it to, 'do not debug javascript from the following domains'?

The problem now is that when i click on the submit button, i dont get that error messsage, saying that LineManagerEmail is required.

It simply goes to the httppost create action (which has no logic in it for now and simply redirects to the index action.

Web Forms :: Multiple Error Messages Of A Validator Next To Textbox?

Sep 30, 2010

I'm having a registration form with textboxes that have more than one validator, e.g. a requiredfieldvalidator and a comparevalidator. I want the error message to show up on the right side of the textbox, but because I use more than one error message, one of them is not neatly next to the textbox, but further away from it.

Html.ValidationSummary Showing Duplicate Error Messages

Nov 30, 2010

I have searched and Googled for the answer to this question to no avail. I'm using EF4 and ASP.NET MVC2 and I have an EF4 entity "Award" with a non-nullable string field, "RecipientID". I'm using DataAnnotations for server-side validation, so in my "Award" partial class I've set up the RecipientID to have the Required attribute. When I try to submit the form with the RecipientID text box empty, I see my error message "Please enter a recipient" in the Html.ValidationSummary twice.

Would this be because the error is being thrown both by the entity (in that it is a non-nullable field with a null value), as well as the application? Whatever the reason, is there a way to "fix" this and have the error message show up only once? (Fix being in quotations because I'm not sure if this is intended behavior or not.) I didn't think it would be necessary to include relevant code, but I will if it's needed.

Ignore Specific Error Messages In Global.asax?

Jan 17, 2011

In the global.asax file, I capture the error details (if one occurs) and I have it send that error detail to an email address.

I am finding that it's reporting all sorts of strange ones when the website gets hit with a crawler....or at least I think it is. ( HTTP_USER_AGENT: Mozilla/4.0 (compatible; Synapse)).

The following are common errors that repeat multiple times at the same date and time:

Error Message: Input string was not in a correct format.
Error Message: Invalid character in a Base-64 string.
Error Message: Unable to validate data.
Error Message: The serialized data is invalid.
