Thanksanishdevasia,
But I do not see any difference in your code over mine, except yours is in C# and I am using VB.
The problem is when I change from default "No" in the RadioButtonList to "Yes" my other controls become enabled, but if a user changes their mind and changes their selection on the RadioButtonList back to "No" after changing to "Yes" my controls do not Disable like my code behind instructs.
If I have these controls outside my UpdatePanel they work perfectly.
Ok I got it working, for some reason if I change my code from SelectedValue toSelectedItem.Value the controls will enable and disable if a user changes their selection multiple times, not sure why but it works.
Thanks,
