Becuase you just delete row from datagrigview not from the database..

"I have a datagrigview connected to a database"

Ah, but you don't; there are several layers in between. One of which is a DataTable, on which you probably need to AcceptChanges. And another of which may be a DataAdapter, on which you probably need to Update.

All-in-all; you may find database work easier if you avoid DataAdapters.

Try this:

C#

string deletestr = "delete from Glasses where id= '" +
                              (((DataRowView)bindingsources.Current).Row[9].ToString()) + "'";

           using (SqlCommand sqlCmd = new SqlCommand(deletestr, SqlConnction))
           {

                try
                  {
                   SqlConnction.Open();
                   sqlCmd.ExecuteNonQuery();
                   SqlConnction.Close();
                  }
                catch (Exception)
                 {
                  //show error
                 }

           }

Solution 2

Check the value as the follows:

string value_ID = ((DataRowView)bindingsources.Current).Row[9].ToString();

I think the value won't be the id value what you are looking for.

The other solution can be if you delete the single quotes from your delete script.
