Update ComboBox and clean record on RadioButton exchange

I have a RadioButton (Risk Type) and a ComboBox (Risk). For each item of the RadioButton selected, a different content is brought into the ComboBox, always aligned with what was selected. For example, if the RadioButton selected is Physical Risk, the ComboBox will show several items searching in the Physical Risk column.


Content in Dataverse. All are ChoicesContent in Dataverse. All are Choices

  1. How can I clear the ComboBox when changing the item on the RadioButton?
  2. How to save the ComboBox item since in Update it says that it waits for an OptionSetValue?

Hello @Deivid ,


1. You can clear the ComboBox with "Reset()" in the "OnSelect" of your Radiobutton.


2. Could you explain a bit more on this point? Are you using "Update()" to update the record? Why not use "SubmitForm()" since you're using a Form? 

Hi @WiZey,


  1. It worked, thank you.
  2. The Update is to update the Risk card, where the ComboBox is. The SubmitForm I'm using for the form.

I'm not certain of the cause, so let's try different solutions.


1. Try « ComboBox.Selected.Value » or « ComboBox.Selected.Result » in your "Update"


2. Try « {Value: ComboBox.Selected.Value} » in your "Update"


Be sure to reference your ComboBox in "Update", I'm not certain if referencing the DataCard is enough for PowerApps to retreive the selected item.

Hi @WiZey,


I'm still not able to save in the ComboBox. Here are the tests on Update:


  • DataCardValue156.Selected.Result
    The name is not valid. The 'Result' is not recognized.
  • DataCardValue156.Selected.Value
    The name is not valid. The 'Value' is not recognized.
  • {Value: DataCardValue156.Selected.Value}
    Expected OptionSetValue value.
    Invalid use of '.'.
  • Value: DataCardValue156.Selected.Value
    The name is not valid. The 'Value' is not recognized.

If neither "Value" or "Result" are recognized, then could you check what is the name of the column in the "Selected" that stores the value?

Following are Dataverse columns that may be in the ComboBox:




As the content that will be in the ComboBox can come from 5 different columns of the Dataverse (as the user selects in the RadioButton), I did the following test:




The error appears in the colon (:), the error says:


Unexpected characters. The formula contains 'Colon', where 'ParenClose' is expected. Unexpected characters. Characters are used in the formula unexpectedly.Unexpected characters. The formula contains 'Colon', where 'ParenClose' is expected. Unexpected characters. Characters are used in the formula unexpectedly.


Hope I answered what I needed to check.

The formula is wrong, you can't fill in "Update" based on a "If()".


When you tried to give it "Selected.Value" and it told you that "Value is not recognized", it meant the "Selected"'s column was neither named "Value" or "Result" but something else.


Could you check what is the column's name inside your "Selected" please?

Good to know about If() in Update, thanks.


I hope the image below answers what you need, if not, how can I get that answer?

What I want to check is what are the columns of "Selected".


For example, my ComboBox has "Selected" property, and "Selected" has "Value" column.




In your app, it didn't recognize "Value" and "Result", so I wanted to check what is the name of the column "Selected" returns.
