Grayed out field based on control?

[myonlywan]

Is it possible to grayed out a field based on checked box instead of using the visible option?

Hi myonlywan

You can use the control 'DisplayMode' instead of 'Visible':

I suggest something like:

1. OnVisible property of screen:

UpdateContext({ChangeDisplayMode: DisplayMode.Edit})

2. Set DisplayMode property of your field to: 

ChangeDisplayMode

3. OnSelect property of your checkbox is:

UpdateContext({ChangeDisplayMode: DisplayMode.Disabled})

Let me know if that resolves your query.

Hi @myonlywan,

Could you please share a bit more about your app's configuration?

I have made a test on my side, please take a try with the following workaround:

Set the DisplayMode property of the field (that you want to gray out) to following formula:

If(Checkbox1.Value=true,DisplayMode.Disabled,DisplayMode.Edit)

Note: The Checkbox1 represents the Checkbox control within your app.

Thanks, it seem working now,..

in my case, if a user wanted to give comments, he will check the box "Comments"

and the comment text box will be editable. 

What would i need to change if i need the checkbox to be unchecked when a new form is created.

I tried checkbox default to false.but it doesnt work.What else must i change?Thanks so much

Hi @myonlywan,

Please take a try to set the Default property of the Checkbox control (Checkbox1) to following formula:

If(EditForm1.Mode=FormMode.New,false,true)

Note: The EditForm1 represents the Edit form control within your app.

Set the DisplayMode property of the field (that you want to gray out) to following formula:

If(Checkbox1.Value=true,DisplayMode.Edit,DisplayMode.Disabled)

Best regards,

Kris
