DataGridView set column cell Combobox

I have tables like that in Datagridview:

Name Money
-------------
Hi 100 //here Combobox with member {10,30,80,100} to choose
Ki 30 //here Combobox with member {10,30,80,100} to choose


I want to change Column "Money" Value from combobox

I tried with this but dont know further:

DataTable dt = new DataTable();
dt.Columns.Add("Name", typeof(String));
dt.Columns.Add("Money", typeof(String));
dt.Rows.Add(new object[] { "Hi", 100});
dt.Rows.Add(new object[] { "Ki", 30});

DataGridViewComboBoxColumn column = new DataGridViewComboBoxColumn();
var list11 = new List<string>() { "10", "30", "80", "100" };
column.DataSource = list11;
column.ValueMember = "Money";
dataGridView1.Columns.Add(column);

Answer

Try this

dataGridView1.AutoGenerateColumns = false;

DataTable dt = new DataTable();
dt.Columns.Add("Name", typeof(String));
dt.Columns.Add("Money", typeof(String));
dt.Rows.Add(new object[] { "Hi", 100 });
dt.Rows.Add(new object[] { "Ki", 30 });

DataGridViewComboBoxColumn money = new DataGridViewComboBoxColumn();
var list11 = new List<string>() { "10", "30", "80", "100" };
money.DataSource = list11;
money.HeaderText = "Money";
money.DataPropertyName = "Money";

DataGridViewTextBoxColumn name = new DataGridViewTextBoxColumn();
name.HeaderText = "Name";
name.DataPropertyName = "Name";

dataGridView1.DataSource = dt;
dataGridView1.Columns.AddRange(name, money);

Just use DataPropertyName instead of ValueMember
