If you´ve already defined a DataSource, You can get the DataGridView´s DataSource and cast it as a Datatable.

Then add a new DataRow and set the Fields Values.

Add the new row to the DataTable and Accept the changes.

In C# it would be something like this..

DataTable dataTable = (DataTable)dataGridView.DataSource;
DataRow drToAdd = dataTable.NewRow();

drToAdd["Field1"] = "Value1";
drToAdd["Field2"] = "Value2";

dataTable.Rows.Add(drToAdd);
dataTable.AcceptChanges();

You can do:

DataGridViewRow row = (DataGridViewRow)yourDataGridView.Rows[0].Clone();
row.Cells[0].Value = "XYZ";
row.Cells[1].Value = 50.2;
yourDataGridView.Rows.Add(row);

or:

DataGridViewRow row = (DataGridViewRow)yourDataGridView.Rows[0].Clone();
row.Cells["Column2"].Value = "XYZ";
row.Cells["Column6"].Value = 50.2;
yourDataGridView.Rows.Add(row);

Another way:

this.dataGridView1.Rows.Add("five", "six", "seven","eight");
this.dataGridView1.Rows.Insert(0, "one", "two", "three", "four");

Consider a Windows Application and using Button Click Event put this code in it.

dataGridView1.Rows
                .Add(new object[] { textBox1.Text, textBox2.Text, textBox3.Text });

Lets say you have a datagridview that is not bound to a dataset and you want to programmatically populate new rows...

Here's how you do it.

// Create a new row first as it will include the columns you've created at design-time.

int rowId = dataGridView1.Rows.Add();

// Grab the new row!
DataGridViewRow row = dataGridView1.Rows[rowId];

// Add the data
row.Cells["Column1"].Value = "Value1";
row.Cells["Column2"].Value = "Value2";

// And that's it! Quick and painless... :o)
