I am using a treeview and the treeview-nodes will be loaded from a xml-file.
It uses a DataSet to do this.
1. Is there a tool where i can check the syntax of my xmlfile?
2. I have an error message:
"Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints."
And I don't know what it means and what to do about it?
Who knows the answer and is willing to help me?
