Validating event net

If the focus is moved to a cell in the same row, then no other events occur.If the focus is moved to a cell in another row, then both Row Validating and Row Validated are fired, containing the whole row data, including the new and the old values of the edited cells.Click Here to read that article and then return to this one. For example, this might come in handy if you had a two stage validation. A call to Validate can be triggered by code elsewhere, but it still doesn't trigger the Validating and Validated events as shown below.--------Click Here to display the illustration--------The second is to call Validate from a container control where the controls that you want validated are child controls.Implicit validation occurs when Auto Validate for the form is set to Enable Prevent Focus Change (the default) or Enable Allow Focus Change. But each control has a Validating and Validated event with a Console. Here's a partial snippet: Private Sub Text Box1_Validating( By Val sender As Object, By Val e As System.

Write Line("Text Box1 Validated") End Sub Your validation code ... When Auto Validate is set to Disable, calling Validate does nothing, even though it might appear to 'work'.--------Click Here to display the illustration--------In this case, there are two ways to trigger the execution of the Validating and Validated events.

I mean, the Validating events were supposed to be there to solve the problem with the Lost Focus/Set Focus issue. Plus, I'm not trying to get it to work, I'm trying really to figure out if this is intended operation, and if so why.

Currently the validation occurs on row and cell level.

To get notified, you can use the following events exposed by the Rad Grid View control: It is important to know that each one of the validation events is fired only when the user is trying to commit new data in the Rad Grid View control.

The validation events are meant to support the data validation of the user input.
