I would like to set a checkbox to the default value when DisplayMode of another datacard is Disabled. The DisplayMode of the datacard depends on several conditions. Any suggestion would be appreciated!

@niga Create a variable, set it's value as per you requirements, based on "several conditions".

Then you can use this variable at both the places, to set the display mode of datacard as well as default value of checkbox, like:

If(myVariable = "DisableCard", DisplayMode.Disabled, DisplayMode.Edit)

Similarly you can use condition based on variable to set the default value checkbox.

Thank you for your response. But I'm still struggling.

Could you tell me where I can set a variable? If I understand correctly, particular kinds of "action" (such as OnSelect of a button) are necessary to set a variable. Is this correct? I
have no such kind of "action" type control.

What I want to do is to set a value of a checkbox to the default value when a property (a DisplayMode in my case) of a datacard is a specific value (Disabled, for example), but I don't want to do anything when the property is the other value (like Edit).

If there is a way to set a value of a checkbox triggered by the change of a property of a control, that would also work for my case, probably.

Hi @niga ,

I think a good way is to insert a Timer control into the datacard.

1\ Set the Timer control 's OnTimerEnd property to:
If(Title_DataCard1.DisplayMode=DisplayMode.Disabled,Reset(Checkbox1))

2\ Set the Timer control 's other propertyies to:
