Update Data Card from SharePoint List with UpdateContext

[Nusserdt]

I have a SharePoint List mylist. In PowerApps I connect the List with my App and create a Formular (create new entry mode). I have to set the Value of the DataCard programmatically with a Button. For that I follow this Guid: Updating a Data Card from a Button

What I understand:

1. Create a Variable myvar in OnVisible in Screen
2. put myvar in the Default property of the DataCard or the DataCardValue (?)
3. in Button add OnSelect event to update the Value of myvar with UpdateContext({myvar:"1"})
4. the value of the DataCard will be the Value of myvar -> 1

My problem with these steps is that setting the Default property of my DataCard is not possible.

• DataCardValue -> Default -> Parent.Default
• DataCard -> Default -> ThisItem.ColumnName

This behavior is potentially related to the SharePoint List mylist. Maybe I have to configure something in SharePoint?

How can I solve it?

Hi @Nusserdt 

Did you unlock your card before you attempted to change the default properties?
