I have a group of radio buttons with 3 choices (app.mode1, app.mode2, and app.mode3) in app-designer. When a user clicks one of the radio buttons, I want the name of a separate button to be changed to something else. For example: mode 1: "load", mode 2: "plot", mode 3: "display". I'm able to create a call back for the group of radio buttons as below:
function modeSelectionChanged(app, event)
selectedButton = app.mode.SelectedObject;
end
end
But I have no idea as to how to write the following codes. Would someone please help me out?
Many thanks!

Assuming your button has the name app.Button, and your radio buttons are labeled 'Mode1', 'Mode2', and 'Mode3', something like this
% Selection changed function: Mode
function ModeSelectionChanged(app, event)
selectedButton = app.Mode.SelectedObject;
switch selectedButton.Text
case 'Mode1'
app.Button.Text = "Load";
case 'Mode2'
app.Button.Text = "Plot";
case 'Mode3'
app.Button.Text = "Display";
end
end

Apologies for necromancing the thread. I don't fully understand how the solution involving values works. It is my understanding that selectedButton is a button object. For radio buttons, button.Value is either 0 or 1. My confusion is regarding how selectedButton.Value works in the example since it is now corresponding to the index of the button rather than the Boolean value?

You are correct. A button can only have a value of 0 or 1. If there are more than 2 butttons, you cannot use value to determine which button has been selected.
