Add New Row in GridView winform on Button Click - c#-4.0

Question

Add New Row in GridView winform on Button Click.
Need to have single button in grid rather than DataGridViewButtonColumn

Answer 1

you can add it by using
GridView1.DataSource = datatable;
and then add new row by this
datatable.Rows.Add();
this will add new row and give control id into add().

Answer 2

use this
public partial class Form1 : Form
{
Button textBoxDgv1 = new Button();
Label labelDgv1 = new Label();
the next is on the Form_Load event
private void Form1_Load(object sender, EventArgs e)
{
labelDgv1.Text = "Delete";
labelDgv1.Height = 20;
labelDgv1.AutoSize = false;
labelDgv1.BorderStyle = BorderStyle.FixedSingle;
labelDgv1.TextAlign = ContentAlignment.MiddleCenter;
int Xdgv1 = this.dataGridView1.GetCellDisplayRectangle(2, -1, true).Location.X;
labelDgv1.Width = this.dataGridView1.Columns[2].Width + Xdgv1;
labelDgv1.Location = new Point(0, this.dataGridView1.Height - textBoxDgv1.Height);
this.dataGridView1.Controls.Add(labelDgv1);
and one more section is in dataGridView1_CellPainting
private void dataGridView1_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)
{
int sum = 0;
for (int i = 0; i < this.dataGridView1.Rows.Count; i++)
{
if (dataGridView1.Rows[i].Cells[3].Value != string.Empty)
{
sum += Convert.ToInt32(this.dataGridView1[3, i].Value);
}
}
textBoxDgv1.Text = sum.ToString();
int Xdgvx = this.dataGridView1.GetCellDisplayRectangle(2, -1, true).Location.X;
labelDgv1.Width = this.dataGridView1.Columns[2].Width + Xdgvx;
labelDgv1.Location = new Point(0, this.dataGridView1.Height - textBoxDgv1.Height);
textBoxDgv1.Width = this.dataGridView1.Columns[3].Width;
Xdgvx = this.dataGridView1.GetCellDisplayRectangle(3, -1, true).Location.X;
textBoxDgv1.Location = new Point(Xdgvx, this.dataGridView1.Height - textBoxDgv1.Height);
}
