The DataGridView is bound to a bindingsource witch in turn gets the data from a table adapter which is filled with data from a "SELECT * FROM TABLE" query
Every checkbox in the datagrid represents a column in the table, there are 30 such columns in the table (bool columns) and therefor there are 30 such columns in the datagrid.Think of a table with 32 columns where 30 of them are Bool values the other 2 are int values (one of those...
