Wouldn't this always be true? I mean, if it's the selected radio button in a group of radio buttons, its value is true. How could it be anything else? Selecting it means that you're setting it true, by definition.

Yes, you have simply to select the property you want (i.e. 'Value', 'Tag' etc..) If you want the Tag of the radiobutton selected you should do so:

u = get(get(handles.uipanel12,'SelectedObject'), 'Tag');

by default one radio button is selected in button group but i want initial no radio button selected with Buttongroup

[Walter Roberson]

praveen chandaliya : That does not appear to be possible in R2014b or later. It appears to me that the first button added to a uibuttongroup automatically has its Value set to 1.

Your options are:

1. set() the Value of the first button to 0 after it is added to the uibuttongroup; or
2. create a junk button first and add it to the uibuttongroup, and then after the other buttons are added, delete the junk button.

@ Walter Roberson Is it possible to set values of subsequent radio buttons to '3' and '4' ? So that when i select third or fourth radio buttons, only code relevant to that part is executed?

[Walter Roberson]

The Value property of a button will be equal to the button's Min property if the button is not selected, and equal to the button's Max property if the button is selected.

So you could set the buttons to have 'Max', 1 for the first button, 'Max', 2 for the second, 'Max' 3 for the third, and so on. Then the Value property of the current button would tell you which of the buttons had been selected.
