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细胞类型？如果是，那么如何？
有两种方法可以做到这一点：
- Cast a
DataGridViewCell到存在的某种细胞类型。例如，转换一个DataGridViewTextBoxCell to DataGridViewComboBoxCell type.
- 创建一个控件并将其添加到控件集合中
DataGridView，设置其位置和大小以适合要托管的单元格。
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;
}
