Preserving state of radio controls

[Antonio Maciel]

Hi.

One custom control I am creating generates a series of radio buttons. These
are html radio buttons, not the server version. When I run the control the
radio buttons are created ok, so I click one of them and refresh the page.
The selected option disappears. How can I preserve the selection when the
user refreshes the page, or when he switches to another page and back? Do I
need to use session variables?

Thanks,

Antonio Maciel

Hi Antonio,

If you want your radiobutton's to preserve state you will need to examine
the posted form data and update them accordingly so when they render they do
so in the same state they were when they posted. This is what the
RadioButton type already does, so you may want to consider writing a
composite custom control and having some RadioButton childs.
