Using DataGridView to Update Multiple Tables

2
votes

On a VB.NET 2008 form I have a DataGridView, BindingSource and TableAdapter.

The BindingSource DataSource is a dataset.

In the dataset I have a Fill command that joins three tables and this is displayed without a problem in the DataGridView.

However, I am unable to Update the dataGridView because it has multiple tables from a single TableAdapter?

Does anyone know a simple way I can update. The tables has over 200 columns and I only want to update the columns that are changed. If I use a single table I can edit data in the DataGridView and the database is updated ok.

Any help would be appreciated?

Thank you.

Unfortunately, the Windows.Forms BindingSource, does not support complex properties (which I assume you are after).

You would have to craft your own custom BindingSource (and it will likely be bespoke to you) to handle complex property values and assignments.
