[MonoTouch] Monotouch.Dialog: how to preselect an element from a RadioGroup?

[René Ruppert]

Hi,

 

This is duplicate from SO
(http://stackoverflow.com/questions/9518598/monotouch-dialog-how-to-preselec
t-an-element-from-a-radiogroup) but maybe the MT.Dialog pros can be found
here and not on SO, so I’ll give it a try:

 

I have an element in my Monotouch.Dialog Controller that discloses a list of
possible selections (RadioGroup with many RadioElements).

If one of the elements is picked, I pop one controller of my stack and the
element that showed the subitems now shows the selected item’s value.

 

However, if the dialog gets initialized I want to set the element's current
value.

I tried setting the section's "Selected" property but that does not seem to
do the trick.

 

I noticed that the RadioGroup constructor has an index that allows selecting
but how can I change the selection *afterwards*?

 

René
