Populate datagridview combobox
提问by user2985344
I have the following code on my windows form load:
我的 Windows 窗体加载中有以下代码：
private void Panou_Load(object sender, EventArgs e)
{
List<string>[] list;
//list in a array with all elements from a select query
list = Conexiune.Select();
dataGridView1.Rows.Clear();
for (int i = 0; i < list[0].Count; i++)
{
int number = dataGridView1.Rows.Add();
dataGridView1.Rows[number].Cells[0].Value = list[0][i];
dataGridView1.Rows[number].Cells[1].Value = list[1][i];
dataGridView1.Rows[number].Cells[2].Value = list[2][i];
dataGridView1.Rows[number].Cells[4].Value = list[4][i];
dataGridView1.Rows[number].Cells[5].Value = list[5][i];
dataGridView1.Rows[number].Cells[6].Value = list[6][i];
}
}
On my datagridview the 4th cell is a combobox. How can I populate the combobox with the value from my select (list[3][i] variable)?
在我的 datagridview 上，第 4 个单元格是一个组合框。如何使用我的选择（list[3][i] 变量）中的值填充组合框？

Set a DataSource for the comboBox column
为组合框列设置数据源
(dataGridView1.Columns[0] as DataGridViewComboBoxColumn).DataSource
= new List<string> { "Apples", "Oranges", "Grapes"};
for (int i = 0; i < list[0].Count; i++)
{
int number = dataGridView1.Rows.Add();
dataGridView1.Rows[number].Cells[0].Value = list[3][i]; //list[3][1]=="Apples"
}
}
