set all elements in checklist to on depending on checkbox

Hello,

I wonder how to select/deselect all elements of a CheckList Control via a single additional CheckBox control.

Thx
Markus

Hello Markus,

In order to achieve this you can proceed like this:
- Go to "Dialogs" page and add a new dialog to your project.
- Add a check list control like this:

Property Name: CHECK_LIST
Values Separator: |

- Select the check list and from its context menu choose "Control Data..." option. In the "Control Data" dialog add the following items using [New...] button:

Text: first
Value: 1

Text: second
Value: 2

Text: third
Value: 3

- Add a check box control like this:

Property: CHECK_BOX
Value: checked

- Select the check box control and add two "Set installer property value" published events like this:

Name: [CHECK_LIST]
Argument: 1|2|3
Condition: CHECK_BOX = "checked"

Name: [CHECK_LIST]
Argument: ""
Condition: CHECK_BOX <> "checked"

- Build and run your project.

Let us know if this helped.

All the best,
Daniel

Thx Daniel,

that works great - now is the checkbox actually a tristate checkbox?
Similar to other installers I would like the checkbox to go into a 3rd state once any item but not all items are selected in the checklist.
I also came across the problem there that the checklist does not have an option to add Published Events?

Thx for your help

No, the check box is a two-state control. I'm afraid you cannot obtain this behavior.

Unfortunately, you cannot have a published event set for a check list control.

All the best,
Daniel
