I am using 4 required field validators,4 regular expression validators and 4 compare validators for 4 text boxes.Is it possible to show error messagesin an alert or message box when validation fails?If possible please send code sample.
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.
Code: Protected Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load Try Response.Write(Session("ValidUser").ToString & "<br />") Catch ex As System.Exception Response.Write("Valid User Session Variable Not Found: " & ex.ToString & "<br />") End Try
This the page that users are redirected to after logging on and, after verifying their credentials at the log-on stage, should show 'Hello DonaldDuck@Disney.com, Welcome to my website'.
Do these errors mean that the user cannot be validated in the database?
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.
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 ???
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.
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?
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".
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(" ", " "); else message = "An error occured while attemting to perform the last action. Sorry for the inconvenience.";
I read this http://blogs.msdn.com/b/kcwalina/archive/2007/01/30/exceptionhierarchies.aspx 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.
Is it possible to style error messages such as InvalidPasswordErrorMessage which is used in the login control. How to set a CssClass property? In addition to doing it hardcoded, it it even possible to do it dynamically?
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 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'.
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.
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.
I've read some articles about how to customize the look and feel of CreateUserWizard but none of them showed me if I can display my error messages somewhere else in the layout. Currently, they appear right above the register button. I'd like to display them next to the table so that there's plenty of space.
