有两种方法可以做到这一点:
1)。将 DataGridViewCell 转换为存在的特定单元格类型。例如,将 DataGridViewTextBoxCell 转换为 DataGridViewComboBoxCell 类型。
2)。创建一个控件并将其添加到 DataGridView 的控件集合中,设置其位置和大小以适合要托管的单元格。
请参阅下面叶志新的示例代码,其中说明了这些技巧:
private void Form_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;
}
MSDN 参考:如何在 DataGridView 控件的同一列中托管不同的控件
使用第一种方法如下所示:
