Possible to change SelectedIndex in RBL thru JavaScript? 1

[EDB2]

Is it possible to change the SelectedIndex of a RadioButtonList through JavaScript?

When a user uses the browser back button to return to the previous page, the page displays without reloading - so the previous selection is still selected. I would like to use the OnClientClick event to remove that selection and leave no element selected in the RadioButtonList when they click the button (forcing them to re-select an item).

I've seen several examples of how to tell which items in a RBL has been selected, but can't find anythign that would actually change the index of the selected item.

There is no such thing as a selectedIndex on a group of radio buttons (assuming you're talking about the same property seen on select lists)

What you'll have to do here to remove the selected item is to loop through each input element on the page, check it's .type property to see if it's a radio button, and if it is then set it .checked property to false.

I have used code similer to this in the past"

function setAllRBLFalse() {
    
   for (counter = 0; counter < form1.YourRBLHere.length; counter++)
      {
        if (form1.YourRBLHere[counter].checked == true)
        {
             
            form1.YourRBLHere[counter].checked = false;                      
        }
            
      }
     
}

Benson, I think that's a better answer than the ones I gave on the other forum, and much simpler. I got thrown off by the fact that the radio button list exists in a table.
