c# - DataGridView 单元格类型

Question

我有带有复选框列的datagridview，但我希望某些列单元格是文本框单元格。
一列中是否可以有多种单元格类型？如果是，那么如何？

Answer 1

有两种方法可以做到这一点：

1. 将 aDataGridViewCell转换为存在的特定单元格类型。例如，将 a 转换DataGridViewTextBoxCell为DataGridViewComboBoxCell类型。
2. 创建一个控件并将其添加到 的控件集合中DataGridView，设置其位置和大小以适合要作为宿主的单元格。

请参阅下面的示例代码，其中说明了这些技巧：

private void Form5_Load(object sender, EventArgs e)
{
   DataTable dt = new DataTable();
   dt.Columns.Add("name");
   for (int j = 0; j < 10; j++) { dt.Rows.Add(""); }
   this.dataGridView1.DataSource = dt;
   this.dataGridView1.Columns[0].Width = 200;

   // First method : Convert to an existed cell type such ComboBox cell, etc 
   DataGridViewComboBoxCell ComboBoxCell = new DataGridViewComboBoxCell();
   ComboBoxCell.Items.AddRange(new string[] { "aaa","bbb","ccc" });
   this.dataGridView1[0, 0] = ComboBoxCell;
   this.dataGridView1[0, 0].Value = "bbb";

   DataGridViewTextBoxCell TextBoxCell = new DataGridViewTextBoxCell();
   this.dataGridView1[0, 1] = TextBoxCell;
   this.dataGridView1[0, 1].Value = "some text";

   DataGridViewCheckBoxCell CheckBoxCell = new DataGridViewCheckBoxCell();
   CheckBoxCell.Style.Alignment = DataGridViewContentAlignment.MiddleCenter;
   this.dataGridView1[0, 2] = CheckBoxCell;
   this.dataGridView1[0, 2].Value = true;

   // Second method : Add control to the host in the cell
   DateTimePicker dtp = new DateTimePicker();
   dtp.Value = DateTime.Now.AddDays(-10);
   //add DateTimePicker into the control collection of the DataGridView
   this.dataGridView1.Controls.Add(dtp);
   //set its location and size to fit the cell
   dtp.Location = this.dataGridView1.GetCellDisplayRectangle(0, 3,true).Location;
   dtp.Size = this.dataGridView1.GetCellDisplayRectangle(0, 3,true).Size;
}
