I 'm using VS2008, to make a windows based applicatin using .net framework 2.0
I made a SQL datababse on my machine (mdf file), new table using the server explorer then on a new form I added the new table from the datasources explorer as a grid view ( by drag and drop )
on running the application after editing and adding new rows , and pressing the save button
nothing is saved
i mean after closing visual studio and opening again or even running the application again ,
the database file has no data
what is missing ??
