Been battling this problem for some time now and could really use some help.
I have an editable datagrid (toolkit version). When a user enters an id nr in one of the cells, my program does a look-up to find the person. While the look-up is in progress, I want the whole window disabled so the user can't tab away and perform other
If I try to set the isenabled flag to false I get: 'NewItemPlaceholderPosition' is not allowed during a transaction begun by 'AddNew'.
I figure it tries to set it to None when disabling.
I've tried to CancelEdit() and CommitEdit() on the datagrid but it fails. Does anyone have any idea how to do this?
