Are you looking for an auto-save feature - then see Auto Saving DataGridView Rows to a SQL Server Database[^].

Here[^] is a decent startup article for DataGridView save.
This[^] may help you as well.

Solution 2

add a hidden column in datagridview
set its to true on 'cellvaluechanged' event
now u can update only those rows by looping the datagridview

very simple: you have some values in datagridview, so now you create one buttons write the following coding within the button.

for(int i=o;i<datagridview1.rows.count-1;i++)
{
string a = dataGridView1.Rows[i].Cells["o_no"].Value.ToString();
string b = dataGridView1.Rows[i].Cells["c_name"].Value.ToString();
string c = dataGridView1.Rows[i].Cells["date"].Value.ToString();
string d = dataGridView1.Rows[i].Cells["kgs"].Value.ToString();

string query = "UPDATE yourtablename SET o_no='" + a + "',c_name='" + b + "',date='" + c + "',kgs='" + d + "' where o_no='" + a + "'";
OleDbConnection con = new OleDbConnection("yourdatabasepath");
con.Open();
OleDbCommand cmd = new OleDbCommand(query, con);
cmd.ExecuteNonQuery();
con.Close();
}
messagebox.show("successfully edited on database");
//now you executed your project.

Solution 4

you can temporary store data to datatable which is easy...

C#

Datatable dt=new DataTable();
dt=griedView1.Source;
