Data Controls :: Insert Data From DataGridView

I used this code:

object filename = @"F:Test.docx";
Microsoft.Office.Interop.Word.Application app = new Microsoft.Office.Interop.Word.Application();
Microsoft.Office.Interop.Word.Document doc = new Microsoft.Office.Interop.Word.Document();
object readOnly = false;
object isVisible = true;
object missing = System.Reflection.Missing.Value;

[Code] ....

It worked. I want insert result from datagridview into database.

Id Separate Number

1 2016_03_30 1
2 2016_03_30 2
3 2016_03_30 3
4 2016_03_30   4
5 2016_03_30    5
6 2016_03_30 5
7 2016_03_30    3
8 2016_03_30    1
9 2016_03_30   2
10 2016_03_30    3
11 2016_03_30    4
12 2016_03_30    5

If separate exists then update else insert.

private void Form1_Load(object sender, EventArgs e) {
this.BindDataGridView();
}
private void BindDataGridView() {
dt.Columns.AddRange(new DataColumn[3] { new DataColumn("Id", typeof(int)), new DataColumn("Separate"), new DataColumn("Number", typeof(int)) });

[Code] ....

I used this script but not insert data into database. It’s only add one row into database.
