Validating event radio group
The first thing that to look at when using radio buttons on our form is how the buttons need to be coded in order for them to function properly as radio buttons.The desired behavior we want is to have only one button selected at a time; when one button is selected then any previously selected button will be automatically deselected.I have used a validation event with an error provider to force the user to place a number in the text box. Is there a simple way to make sure that the user has selected a radio button? You don't need to put this code in any validation event, you can put it wherever you need to make sure a Radio Button is checked.This can be in the click event for a button that saves the current record, etc.
These paths are used frequently in a variety of front-end development and QA automation tasks. Because from what I can see from the code, there is no other form validation that is occurring. If is false, trigger whatever user notifications you need to.If you really need to use one of the Radio Button's validating event, you could create just one such event and wire all your Radio Buttons to use that one event.The setup and validation of radio buttons appears to be the form field that gives many webmasters the most difficulty in setting up.In actual fact the setup of these fields is the most simple of all form fields to validate as radio buttons set one value that only needs to be tested when the form is submitted.
