How to check a html-radiobutton inside a datalist

[ensingg]

Hi,

I like to have a radiobutton inside a datalist using the itemtemplate. (on advice of someone).

In the pageload I like to set the radiobutton to checked.

Inside the itemtemplate there's only

<input type="radio" id="keuze" name="keuze" ..

I cannot get it by using the findcontrol method. Please help. It's making me crazy.

Best regards,
Gert
