Hi@Urbain_Mora,
Do you mean that you want to save Checkbox value to the Choices field in the CDS?
A Choices field could not be used to compare with a Text value, this is forbidden by PowerApps. If I understand correctly, you have a Choices field and you want to display this options using multiple Checkboxes.
A key is that it is difficult to convert the Text to OptionsetValue which is forbidden by PowerApps.
For your needs, I think it over and update the reply as below.
Here is an alternative solution, I think you could consider a horizon Gallery to insert Checkbox values into the Choices.
Add a blank horizontal Gallery outside the form and insert a Checkbox into it.
Set Items property of the Gallery as:
Choices(QiTests.Check)
Set Text property of the Checkbox as:
ThisItem.Value
Set Default property of the Checkbox as:
If(Checkbox11.Text in ThisItem.Value, true, false)
Set Update property of the data card corresponding to the Check column as:
Filter(Gallery6.AllItems,Checkbox11.Value)
Note: My table name is 'QiTests' and my Choices column is 'Check'.
Then you just need to click the submit button to save the choices back to the Table.
Hope it could help.
Regards,
Qi
