[Dropdown].Selected.Value always empty

Hello everyone,

I am currently working on a new Power App, for which I would like to test the ‘modern controls’ for the first time. Unfortunately, I found a strange error relatively quickly. I want to calculate a price based on a selection in a dropdown. For this I use the formula [Dropdown].Selected.Value - Unfortunately, an error already occurs with this simple formula. I can read the value in the ‘Update’ property (within the datacard) as normal. However, if I use this value outside the datacard, it is always empty. I have of course already added the value field within the dropdown.

I hope that someone can help me with this.

Thank you in advance for your answers

Unfortunately there isn't much here that you can take screenshots of, but I'll try to explain it in more detail with the screenshots. Within my app I have a form (modern controls). Here I have marked the relevant field once. As you can see in the screenshot, the RadioButton control is called “RadioGroupCanvas1”

The following screenshot shows the formula and the returned value of the update property

Here you can see that I access the control with RadioGroupCanvas1.Selected.Value and get back the value “Basic”. This is also selected as can be seen in screenshot 1

As already mentioned, I have added the value Value under “Fields”.

To check the value, I added a text label outside my form. As you can see in the following screenshot, I access the control with the same formula and get no value back..

To illustrate this once again, here is a screenshot of my screen: There are several containers in the “Service package detail” screen. The affected form is located in the container “MainContainer1” (Form2). Above it is the label “TextCanvas1”, which I have used for this purpose

Important: In my screenshots, unlike in the description, they are RadioButtons instead of a dropdown - I made this change for testing purposes. I have exactly the same problem with the dropdown control

Hi

You didn't share any pictures, the code (in the proper property), nothing....

Please share your app, and the details so we can see whats there, please don't try to just explain it.
