Solution 1

Well, you have not stated what you have tried and where was the issue when you tried it.

Have a look at these article on how radio buttons are grouped:
Gropu Radio Button[^]
How to group RadioButtons[^]

They are more than enough to understand the logic which can be used for coding your scenario.

UPDATE:
Ok. Fine, try this: (it's in C# that I am writing):

C#

// Do this for getting checked status of all radio buttons
// Similar approch can be done to RESET an uncheck them all
for(int i=0;i<myGroupBox.Controls.Count;i++)
{
   RadioButton rb= (RadioButton)myGroupBox.Controls[i];
   if(rb.checked==true)
   {
      // do whatever
      // use break; if needed
      // increase a counter if you want number
   }
}

This is a specific scenario and exact code should not be expected. If, you are unable to do what you posted then the above links can tell how that can be done. As said, logic couldbe derived from there.
Yet thanks for comment. I will keep in mind for next time with you.

Ok. Fine. Updated my answer by a small code snippet. Try it.

Now, was that fine?

Sandeep, I can't believe you caved! At least it's in C#... at least the OP can't just copy and paste.

Solution 2

Iterate over the children of the groupboxes and check if they are 1) radiobuttons and 2) unchecked.

OP needs *exact* code, please provide. :)

With VB.Net, I presume. Or, did you have a more specific question?
