I've implemented a PCF Control for an Optionset attribute: https://github.com/ORBISAG/ORBIS.PCF.ColorfulOptionset

I try to use it in a CanvasApp. I've imported the Control in my CanvasApp and I've seen that for the bounded property that I've defined in the manifest (optionsInput)

 <property name="optionsInput" display-name-key="Property_Display_Key" description-key="Property_Desc_Key" of-type="OptionSet" usage="bound" required="true" />

i become two properties in the CanvasApp : optionsInput and optionsInput_Options.

I've figured out how to fill the options (by setting optionsInput_Options using Choices function).

But I don't know how to set the value for optionsInput.

So my PCF control gets all the options

 context.parameters.optionsInput.attributes!.Options;

BUT the value is always empty.

context.parameters.optionsInput.raw;

This is my CanvasApp designer:

Hi @DianaBirkelbach ,

Do you want to specify a value within this OptionSet PCF control through the optionsInput property?

Does the PCF control work well after you specified the Choices formula for the optionsInput_Options property?

If you want to set a default value within this OptionSet PCF control through the optionsInput property, please consider take a try with the following workaround:

Set the optionsInput property of the OptionSet PCF control in your app to following:

"A Specific Option from optionsetcode (PCFTesters) field" // single text value

In addition, the Option Set type field provides a set of options. Each option has a number value and label. When added to a form, this field displays a control for users to select only one option. If above formula could not work, please apply the same Choices formula into the optionsInput property.

Set the optionsInput property of the OptionSet PCF control in your app to following:

Choices('optionsetcode (PCFTesters)')

Best regards,

Unfortunately I don't get it to work.
I get all available options passed to my PCF control. It works through setting the optionsInput_Options on
Choices('optionsetcode (PCFTesters)')
When I remove that, I don't get to see any option in my dropdown anymore.
It doesn't work it I set the this Choices... Formula to the optionsInput
What is missing, is a way to tell my control which value was chosen. I've added the same attribute again on the form by using the standard control (optionsetcode). There you can see on the screenshot that the "Gatekeeper" value is shown as soon I open the form. How can I tell my PCF control which value has to be shown/chosen from the list?
The first solution proposal was not accepted by the from designer.
The second one was accepted by the designer only in combination with "First" function
First(Choices('optionsetcode (PCFTesters)'))
but it had no effect.

When I work with a text area control, I could set the input property value by using
BrowseGallery1.Selected.Textarea
So I thought for the optionset PCF should be something like
BrowseGallery1.Selected.optionsetcode
but unfortunately that is not even accepted by the designer.😞

Hi all,

This appears to be a recent regression in this functionality. We are tracking it internally with priority by internal bug ID 1751868 and hope to have it fixed quickly.

Has this been solved yet? I could not find the bug @jolake mentioned.

I am trying to make a custom dropdown which will return the selected option of the optionset so it can be used in the canvas app and that works, but the optionsProperty (not optionsProperty_Options) field does not corespond to the control. How is it meant to be used and connected (working with a react control I tried having a state and props property that should update each other, but this didn't work)?

Is there any update on this @DianaBirkelbach @jolake ?
I would like to be able to set a default selected option for a dropdown I am creating, and in the testharness it works, but in PowerApps, Choices.raw is null.

I also feel like many people are confused on how to use the optionset... Maybe someone can give a better explanation?
