I made nova oledbdataadapte r select update insert and delete command and
connection veza. dataset is Studenti1data, I made it by the new data
source wizard,and made datagridview and bindingsource draging Table1 to
Form2. The select command works fine, but when I change the data and call
update command I get a syntax error:

In the SQL, put field names that contain blanks into brackets:
"...[Broj iksice]..."

It also seems that you are setting many more parameters for the
UpdateCommand than there are available. I count six "?" in the SQL but you
set some more.

In the past, I have filled a datagrid with data from an Access database table using a data adapter and dataset, where I used the OleDbCommandBuilder to have the program create the insert, delete and update commands automatically for the dataadapter. I think those database tables had no more than 10 or 12 fields. Then to save the changes in the datagrid to the database, I simply evoked the dataadapter update command. No problems. ...
