Hi @ATCancom,
Are you working with the SharePoint list custom form, or the Apps built from SharePoint list?
Please first review the limits for the current attachment control:
Attachment control in PowerApps
Quoted:
"
-
Attachment upload only works with SharePoint list data sources. Support for other data sources will be introduced incrementally, starting with CDS.
-
Upload and delete functionality only work inside a form. Attachment control will look disabled when in Edit mode and not inside a form. Note that in order to save the file additions and deletions to the back end, the end user must save the form.
"
Would you please explain a bit for "Now, we have the problem that the content of the 'previously entered value of attachment field' is still shown in every new form."?
If here you would like to submit new record, then please take use of NewForm() function, and if you have added multiple forms, then all the forms should be reset by the NewForm() function. As there is no Reset property available for this control, we need to Reset the form with NewForm(), in order to Reset the controls added within the form.
For SharePoint list custom form, under the OnNew property of the SharePoint integration.
NewForm(Form1);NewForm(Form2);...
For the Apps generated with SharePoint list data source, with the Create "+ " button,
NewForm(Form1);NewForm(Form2);...;navigate(EditScreen, ScreenTransition.Fade )
For how to work with forms, see:
EditForm, NewForm, SubmitForm, ResetForm, and ViewForm functions in PowerApps
EditForm and Display form controls in PowerApps
Regards,
Michael
