How to add a new row to datagridview programmatically

Question

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");

From: http://msdn.microsoft.com/en-us/library/system.windows.forms.datagridview.rows.aspx

Like this:

var index = dgv.Rows.Add();
dgv.Rows[index].Cells["Column1"].Value = "Column1";
dgv.Rows[index].Cells["Column2"].Value = 5.6;
//....

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)

Like this:

 dataGridView1.Columns[0].Name = "column2";
 dataGridView1.Columns[1].Name = "column6";

 string[] row1 = new string[] { "column2 value", "column6 value" };
 dataGridView1.Rows.Add(row1);

Or you need to set there values individually use the propery .Rows(), like this:

 dataGridView1.Rows[1].Cells[0].Value = "cell value";
