Hi,
I have a radiobutton list that changes the contents of a dropdownlist when the selected radiobuttonlist index is changed using the SelectedIndexChanged event. Both controls are within the same updatepanel and both have autopostback set to true.
For some reason when I change the dropdownlist and cause a postback, the radiobuttonlist change event fires and repopulates the dropdownlist which effectively cancels the selection made in the dropdown.
I know something simple must be causing this behaviour but I cannot think what and my debugging efforts are not shedding any light thus far. I have tried putting a breakpoint on every procedure in my form and the first event that fires is the radiobuttonlist SelectedIndexChanged event so nothing in my server side code seems to be doing this which suggests it is something in the markup but I can't think what.
Does anyone have any idea what may be causing this infuriati ...
