In a Win Form I'm doing initial validation in the Form. To make the code short only three fields are shown in the code.

So before saving data, I want to validate whether all the required fields are filled (Text Boxes) by the user. In my windows form projects , i have validated the fields using Boolean method.

For example, if you have code in a Validated event that attempts to cancel the data binding, the data binding will still occur.

In this case, to perform validation in the Validated event, change the control's Data Source Update Mode property (under (Databindings)\(Advanced)) from On Validation to Never, and add The implicit validation approach validates data as the user enters it.

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.

Do I have to write an "else if" statement or is there any operator that I can use to put it all in the same if statement.

I have a form where I need to validate the textboxes like Firstname, Middlename, Lastname, email Id, date, mobilenumber.

If you want full programmatic control over validation, or need to perform complex validation checks, you should use the validation events built into most Windows Forms controls.
