The <dotj:grid> tag is fully integrated with all of the various dotJ HTML form fields (<dotj:input>,
<dotj:select>, etc.). This gives you the capability to allow rich user input when editing a row in the grid. Also,
the <dotj:fieldvalidator> tag is fully supported as well. This gives you an unlimited number of things you can do
for your users to give them the best user experience.
In the example below, select a row and click the Edit button. Once you are editing a row inline, try blanking out the Last Name
or Comments field. You will notice that our standard field error messages alert you that the field is required. Give it a try.
