hi there im a total newb at this programming language
is there a way 3 databases can be in one datagridview?

I can only insert 1 database in a datagrid

DataGridView only binds to one table at a time. Third party controls (such as Infragistics' UltraGrid) support multiple table binding, but if you want to go with standard controls the old DataGrid has some options you could find useful, or your could combine something like a TreeView with a DataGridView to produce something workable.

Here's an example I found that seems very similar to something I wrote myself a few years ago.
