DataGridView 设置列单元格组合框 [英] DataGridView set column cell Combobox

问题描述

我在 Datagridview 中有这样的表格:

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

我想从组合框中更改列Money"值

I want to change Column "Money" Value from combobox

我试过这个，但不知道更多:

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); 

推荐答案

试试这个

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);

只需使用 DataPropertyName 而不是 ValueMember
