I am using ASP.NET's server-side validation. In the page_load event I'm calling Page.Validate(), and if Page.IsValid is not true I'm then polling the controls to figure out which ones are not valid, and then determining what actions to take.It would be much easier if each control would raise an event as validation fails, allowing me to take action for that particular control. I'm very much a naive programmer when it comes to validation, but is there a way to extend these controls so that a validation error raises an event?
I have a text box and some validation on it. I want to make a panel visible only when

I have a project due for my Visual Basic course. The project is creating a web application. I'm setting up the application where the user will enter information in a textbox. I want to be able to test the value entered in the textbox. There are three test conditions - less than a certain number, between a range of numbers, and greater than a certain number. I'm familiar with Visual Basic but not that with Visual Web Developer. I want to display a message to the user that tells them the value entered is low, normal, or high, and display additional information. The question I have is can I attach three validation controls to a single textbox? I know how to attach one validator control, and that works fine. I try to attach three controls but when I run the program all three error messages display, which is not what I want. I think I would need to code a custom validator but not sure how to do that.
I have a page with formview, the page contains a lot of input fields and a lot of validators and when I press "Save" button (in which I perform insert procedure) the form is validated, but button click event and page load happens. Validators and button belong to the same validation group. How to avoid button click and page load events happening when some validators aren't correct? In page without formview everything works ok, I click "Save" button and when all validators are correct only then happens button click event. How to fix that with form view?
