在按鈕上的GridView winform中添加新行單擊

Question

在按鈕上單擊，在GridView winform中添加新行。 必須電網，而不是DataGridViewButtonColumn單按鈕

Answer 1

您可以通過使用

GridView1.DataSource = DataTable中添加它;

，然後通過此

datatable.Rows.Add添加新行（）;

這將添加新行並將控件ID添加到add（）中。

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); 
}
