This tag enables the end-user to define a row by selecting the radio-button rendered by this tag

This tag enables the end-user to define a row by selecting the radio-button rendered by this tag

<tagclass>org.dbforms.taglib.DbAssociatedRadioTag</tagclass> <bodycontent>empty</bodycontent>

example: imagine a table customer, which should be listed. the user should be able to delete a customer.

in that case the application developer has to alternatives: to put a "deleteButton" into the body -> this button gets rendered for every row
if the user klicks the button the associated data row gets deleted. the disadvantage of this method is that multiple buttons must be rendered, which takes away lots of space and makes layouting more difficult to put an "associatedRadio" into the body and the "deleteButton" on the footer (or header)
the radio element gets rendered for every row, the deleteButton just once. if the user wants to delete a row, he/she has to select the radioButton (to mark the row he/she wants to be deleted) and then to press the deleteButton.

the more buttons you have the better this method is!!

nota bene: you have to tell the delete (or insert, update...) - button that there is an associated radio button that marks the row the action should be applied to, by defining the "associatedRadio" attribute of that respective button
