Windows form control validating validated essex county college summer basketball camp

Is there a "best practice" document/site for control validation in a Windows Forms application?Of the many things that are still confusing me, I am unable to find an explanation for the behavior of my dialog when the Ok button Dialog Result property is set to return Dialog Result. Why does setting this property interfere with validation? None seems to change some automatic behavior of the Form class. I think it is easy to use while also fulfilling all the other requirements.You can assign one of these properties or all of them if you need to perform multi-level validation.For example you can require the input for text-box and enforce the format to be an email by assigning Validation1 and Validation2 properties.Select control you want to assign validation to and change its Validator1 property to choose desired validation type.In previous example you’ve seen required field validator.You can use this for example to ensure that password entered matches the confirmation password on input form or to ensure that numeric input value is greater than number you specify.

I am trying to better understand how validation works in a Windows Forms application.Super Validator can work with any of these components set or without any of them at all if you are planning to report validation results some other way.Next step is to choose the way Super Validator performs validation.Let’s assume when we click our save button that we wish to validate the controls and display an icon if there is a problem.First, add the following code to the Form’s constructor after the Initialize Component method: This is a handy trick to prevent implicit validation of our controls when they lose focus.
