How does the custom page Values[] array work in Inno Setup?

For example:

1. Panel
2. Label
3. Radio
4. Radio
5. Radio
6. Panel
7. Label
8. Radio
9. Radio
10. Label
11. Combo
12. Label
13. Label
14. Text
15. Button

Does the Values array match all of the controls on the page, or only the radio, combo, text controls?

The generic custom page has no Values property.

Only special implementations of a custom page do. And their meaning differs with the implementation.

• CreateInputQueryPage/TInputQueryWizardPage – Values refers to text value of edit boxes added by TInputQueryWizardPage.Add.

• CreateInputOptionPage/TInputOptionWizardPage – Values refers to state of checkboxes/radiobuttons added by TInputOptionWizardPage.Add.

• CreateInputDirPage/TInputDirWizardPage – Values refers to text value of edit boxes added by TInputDirWizardPage.Add.

• CreateInputFilePage/TInputFileWizardPage – Values refers to text value of edit boxes added by TInputFileWizardPage.Add.

If you want to refer to a value of a custom control added to a generic custom page, use the instance of the control. There's no (nice) way to refer to the control value via the container page.

• TNewEdit.Text – See Edit installed XML file according to user preferences in Inno Setup
• TNewCheckBox.Checked – See Inno Setup: How to show (hide/unhide) password on checkbox checked
• TNewRadioButton.Checked – See Replacing Inno Setup installation type combo box with radio buttons on separate page (Install Shield like) or How to create two LicenseFile pages in Inno Setup
• TNewCheckListBox.Checked – See How to split tasklist at tasks page of Inno Setup into multiple columns?
• etc.

That usually means that instances of controls you want to query later have to be global variables. See Reading values from custom Inno Setup wizard pages without using global variables or Access to custom control from OnClick event of another control in Inno Setup.
