Adding Something to DataGridView－天天向上

原本只想在DataGridView加入ComboBox的功能, 結果網路一查之下, 發現這也是一門學問,

.NET已經將一些常用的如

DataGridView + ComboBox

DataGridView + CheckBox

DataGridView + Button

DataGridView + Image等諸如此類的元件都已經整合在一起, 真是棒!

但是有些還是得自己手動加入

DataGridView + NumericUpDown

DataGridView + RadioButton

網路上的MSDN範例又臭又長,實在難以下嚥,

幸運地, 花了一點時間總算找到一個簡單一些又可行的範例, 有時間再來慢慢消化囉!

先把目前的資料整合成一個範例程式, 有需要的人可以下載最後面的sample code^_^

Add DataGridView component to windows form

   1: private void button1_Click(object sender, EventArgs e)   2: {   3:        4:     dataGridView1.ColumnCount = 3;                             // 定義所需要的行數   5:     dataGridView1.Columns[0].Name = "Product ID";   6:     dataGridView1.Columns[1].Name = "Product Name";   7:     dataGridView1.Columns[2].Name = "Product Price";   8:     string[] row = new string[] { "1", "Product 1", "1000" };  // 定義一列的字串陣列   9:     dataGridView1.Rows.Add(row);                               // 加入列    10:     row = new string[] { "2", "Product 2", "2000" };  11:     dataGridView1.Rows.Add(row);  12:     row = new string[] { "3", "Product 3", "3000" };  13:     dataGridView1.Rows.Add(row);  14:     row = new string[] { "4", "Product 4", "4000" };  15:     dataGridView1.Rows.Add(row);  16: }

執行結果

   1: private void button2_Click(object sender, EventArgs e)   2: {   3:     DataGridViewComboBoxColumn cmb = new DataGridViewComboBoxColumn();   4:     cmb.HeaderText = "ComboBoxColumn";   5:     cmb.Name = "cmb";   6:     cmb.MaxDropDownItems = 4;   7:     cmb.Items.Add("True");   8:     cmb.Items.Add("False");   9:     cmb.Items.Add("100");  10:     dataGridView1.Columns.Add(cmb);  11: }

   1: private void button3_Click(object sender, EventArgs e)   2: {   3:     for (int i = 0; i < dataGridView1.RowCount - 1; i++)   4:     {   5:         dataGridView1.Rows[i].Cells[3].Value = "True";   6:     }   7: }

   1: private void button4_Click(object sender, EventArgs e)   2: {   3:     for (int i = 0; i < dataGridView1.RowCount - 1; i++)   4:     {   5:         dataGridView1.Rows[i].Cells[3].Value = "False";   6:     }   7: }

   1: private void button5_Click(object sender, EventArgs e)   2: {   3:     DataGridViewCheckBoxColumn chk = new DataGridViewCheckBoxColumn();   4:     5:     chk.HeaderText = "啟動";   6:     chk.Name = "chk";   7:     dataGridView1.Columns.Add(chk);   8: }

   1: private void button6_Click(object sender, EventArgs e)   2:  {   3:      for (int i = 0; i < dataGridView1.RowCount - 1; i++)   4:      {   5:          dataGridView1.Rows[i].Cells[4].Value = true;   6:      }               7:  }

   1: private void button7_Click(object sender, EventArgs e)   2:  {   3:      DataGridViewImageColumn img = new DataGridViewImageColumn();   4:      Image image = Image.FromFile("c:\\bg.jpg");   5:      img.Image = image;   6:      dataGridView1.Columns.Add(img);   7:      img.HeaderText = "背景";   8:      img.Name = "img";   9:  }

   1: private void button8_Click(object sender, EventArgs e)   2:         {   3:             DataGridViewButtonColumn btn = new DataGridViewButtonColumn();   4:             dataGridView1.Columns.Add(btn);   5:             btn.HeaderText = "Click Data";   6:             btn.Text = "Click Here";   7:             btn.Name = "btn";   8:             btn.UseColumnTextForButtonValue = true;   9:         }

   1: private void button9_Click(object sender, EventArgs e)   2: {   3:     NumericUpDownColumn num = new NumericUpDownColumn();   4:     dataGridView1.Columns.Add(num);   5:     num.HeaderText = "NumericUpDown";   6:     num.Name = "num";   7: }

   1: private void button11_Click(object sender, EventArgs e)   2: {   3:     for (int i = 0; i < dataGridView1.RowCount - 1; i++)   4:     {   5:         MessageBox.Show(dataGridView1.Rows[i].Cells[7].Value.ToString());   6:     }   7: }
