Question

In Delphi 2010, I have placed 2 radio groups onto a form then added 2 buttons to each group. so there are 4 buttons in total.

The problem is that the buttons’ Checked properties behave as if all 4 buttons are in the same radio group. I.e., only 1 of the 4 buttons can be checked at any time. This is true both at design and run time.

  object RadioGroup1: TRadioGroup
    Left = 14
    Top = 314
    Width = 177
    Height = 35
    Caption = 'Series 2 Axis'
    TabOrder = 14
  end
  object RButtonLeftAxis: TRadioButton
    Left = 91
    Top = 326
    Width = 41
    Height = 17
    Caption = 'Left'
    TabOrder = 12
    OnClick = RButtonLeftAxisClick
  end
  object RButtonRightAxis: TRadioButton
    Left = 138
    Top = 326
    Width = 45
    Height = 17
    Caption = 'Right'
    Checked = True
    TabOrder = 13
    TabStop = True
    OnClick = RButtonRightAxisClick
  end

blah blah more objects

  object RadioGroup2: TRadioGroup
    Left = 8
    Top = 146
    Width = 113
    Height = 69
    Caption = 'Output Type'
    TabOrder = 33
  end
  object RadBtnkWh: TRadioButton
    Left = 20
    Top = 165
    Width = 65
    Height = 17
    Caption = 'kWh'
    TabOrder = 34
    OnClick = RadBtnkWhClick
  end
  object RadBtnLossFact: TRadioButton
    Left = 20
    Top = 188
    Width = 81
    Height = 17
    Caption = 'Loss Factors'
    TabOrder = 35
    OnClick = RadBtnLossFactClick
  end

How do I unlink these 2 groups?

Answer 1

It seems you have added radio buttons to TRadioGroup manually. Don’t do that. Just click on the proerty Items of the radio group and write the strings (name of various radio buttons) there. And you get one radio group ready !
