2010 .Net MAster Detail Form Not Saving Record?Nov 15, 2011
I am new to VB.net and have created a simple master detail windows form. I created a two table data set and then dropped the master table on the form as a continues form or a detail form with several text boxes to hold the data. The child form is a data grid.
test data that I have added directly to the database shows up with the proper parent child relationships on the form. I can also enter new records into the database using the parent only portion of my form.
When I attempt to enter a complete record with data in both the parent form and the child data grid I get this error. The INSERT statement conflicted with the FOREIGN KEY constraint
I have searched for a possible reason for this error but can not find any explanation. I have noted in earlier versions of VB.net you had to enter code to save the child record, but the VB 2010 code does not seem to use the same syntax so I assumed the UpdateAll eliminated the need for the extra code
