The process of building custom solutions for SharePoint Server.
Hi, @Dani - ,
According to your description, it seems the web part works fine on updating the ECT column in the source list. The issue is that user need to refresh the page and clear the cache so that the dataform will get updated. Please correct me if I get anything wrong.
By default, we do not have a "dataform" web part in SharePoint 2019. Are you using a list web part or custom web part solution? With the part "The dataform show a “Edit form” from a custom list where I manage 2 field." I will assume it to be a custom one. And without much information about it, it is hard for me to say what makes such issue. Would you like to share more information about it if I have a incorrect assumption about your scenario?
