If you assigned Enable Allow Focus Change, the Validated event will not occur when you cancel the event, but focus will still change to the next control.
Assigning Disable to the Auto Validate property prevents implicit validation altogether.
If you have custom validation that takes place after the Validating event, it will not affect the data binding.
For example, if you have code in a Validated event that attempts to cancel the data binding, the data binding will still occur.
If you assigned Enable Prevent Focus Change, canceling the event will cause the Validated event not to occur.
If you wish to validate specific content such as RSS/Atom feeds or CSS stylesheets, Mobile OK content, or to find broken links, there are other validators and tools available.
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 So when does a control's data get validated? You can use either implicit or explicit validation, depending on the needs of your application.
The implicit validation approach validates data as the user enters it.
You can validate the data in response to a user action, such as clicking a Save button or a Next link.
When the user action occurs, you can trigger explicit validation in one of the following ways: However, in some cases, you might want to let the user close the form regardless of whether the values in the controls are valid.
You can validate the data as the data is entered in a control by reading the keys as they are pressed, or more commonly whenever the user takes the input focus away from one control and moves to the next.
