How To Display Error Message In Asp Net Using C#

Set Validation Error Message Javascript
regular expression validator (for correct format) and custom validator associated with same input field. When validation fires all error messages are shown. I want to be able to display only one message. Is there a way to have just one validator (custom) and display specific error message. How can I controll the error message text for the custom validator. Any ideas? Thanks asp.net custom validator display dynamic Reply jeroenm Participant 1800 Points 502 Posts Re: Custom Validator with multiple error messages Feb 07, 2009 02:26 PM|jeroenm|LINK Hello wesgabi, Can't you use one custom validator that is the combination of the required field, the regular expression and the current custom validator? Or use two extra booleans to indicate that the previous validation passed, e.g. Required field entered? No, display error and set first is invalid. Yes, set firstto valid. Regular expression valid? No, display error and set second is invalid, if first validation valid.Yes, set secondto valid. Custom validation valid? No, display error, if second validation valid. Yes, continue processing. -------------------------------- Jeroen Molenaar.

The question is how can I control the error message text from the javascript function. I need to display different error for each type of validation. I included the sample row from the aspx page. As you see below I am displaying three different messages So once again my question is how ca

Sometimes we use a custom validator control instead of other controls to implement our custom logic to validate user input.We use the ErrorMessage property to display the error message. Assume you get a requirement to display the error message dynamically. Then it will not help to implement it directly (we need to implement it in code behind, not in the aspx page). So we need a way to display the dynamic error message. It can

Join them; it only takes a minute: Sign up Validate on multiple errors with one CustomValidator up vote 2 down vote favorite I am trying to figure out how to use Validation on Business Objects. Until now I have only seen examples on CustomValidator that custom validator checks for only 1 error. I have two fields with DateTime input that should check for 3 or more errors. I guess normally I should check on client, then on server, last on database level. If I get an error on a field, I should not be able to leave the field. On the Client Validation this is not an error that should cause an Exception since it's only a user error. But if something goes wrong and the user bypass asp.net custom validator the Client Validation, the Server Validation should kick an Exception. And last, if i have other e.g. Batch Update work then they should use the Database Validation code. Please correct me if I have missed something fundamental! `dateFrom` is not empty. (But `dateTo`can be empty) `dateFrom` is earlier than `dateTo` `dateFrom` and `dateTo` is within constant `MinDate` and `MaxDate` So How should my Validation look like, Client, Server and Database? Thoughts: Should the validation logic be separated on 3 different places; UI, Code and DataObject(Database)? When it is the exact same code? Seems redundant? Can I use the same validation method for all three checks? Or do I need to implement 3 code-chunks, and 3 Methods for each, and then how do I list all in the ValidationSummary nicely? c# asp.net validation business-objects customvalidator share|improve this question edited Sep 10 '11 at 11:34 Kheldar 3,83431949 asked Feb 22 '10 at 13:44 Niike2 5601619 add a comment| 2 Answers 2 active oldest votes up vote 2 down vote accepted To reduce code duplication and the errors resulting from it, all validation code should be in a single layer - preferably the business layer, as it is in the best position to evaluate the object and determine if it is valid or not. However, while that is a theoretical ideal, it is often not pragmatic in real world situations. In a client-server environment, like ASP.NET, you want to duplicate as much of the
