Hi,
I am trying to add validation to a RadTextBox that will cause validation to occur when the text box loses focus.
The scenerio is: If a user uses the Tab key to move out of a text box that is a reuired field, I am trying to display an error message stating that the field is a required field. I tried using RequiredFieldValidator control, which works fine when user submits, and CustomValidator control setting setting ValidateEmptyText to true.
Is there a way that this can be done client-side without writing JavaScript? If JavaScript needs to be written, what are some of the key calls to make?
Thanks in advance.
