1、ComboBox添加元素
comboBox1.Visible =false;
comboBox1.Items.Add("线性")
comboBox1.Items.Add("非线性")
2、dataGridView添加控件
dataGridView1.Controls.Add(comboBox1);
以上可放在_Load方法内。
3、当选中dataGridView1的指定列时显示comboBox控件，并调整控件的大小与dataGridView1的cell大小一致
private void dataGridView1_CurrentCellChanged(object sender, EventArgs e)
{
try
{
if (this.dataGridView1.CurrentCell.ColumnIndex == 9)
{
Rectangle rect = dataGridView1.GetCellDisplayRectangle(dataGridView1.CurrentCell.ColumnIndex, dataGridView1.CurrentCell.RowIndex, false);
string sexValue = dataGridView1.CurrentCell.Value.ToString();
comboBox1.Left = rect.Left;
comboBox1.Top = rect.Top;
comboBox1.Width = rect.Width;
comboBox1.Height = rect.Height;
comboBox1.SelectedItem = dataGridView1.CurrentCell.Value;
comboBox1.Visible = true;
}
else
{
comboBox1.Visible = false;
}
}
catch
{
}
}
4、 comboBox1选择改变时赋值给dataGridView1
if(dataGridView1.CurrentCell!=null)
dataGridView1.CurrentCell.Value = comboBox1.SelectedItem.ToString();
