Validating event of textbox in c rusian dating girls

I don't know whether this also works in c#2.0, this is my experience in c#3.0: Why do you use Text Box_Leave for that?

The Validating-event should be used for validating whether input is correct.

The problem is that I cannot check if the values in the box are valid or not and prevent the click event in the button to happen.

An Error Provider can also block any submit-actions.

Find the below sample screen shot for validating the fields before saving the data Img 3: Validation method Here I have validated the fields using the Boolean method, If all the field values are entered properly it will return true, other wise it will return false and will display an error message.

I am fairly new to Visual Studio and C# in general but basically I need to check that the contents of the textbox are valid before proceeding to add the contents to a list with a button.

The validation should happen when a user starts typing in the textbox.

errorprovider should show message under textbox if a user enters numbers in place of text and text in place of numbers.If you have a very specific validation to do, Marc's answer is correct.
