DataGridView的一组列单元格组合框 [英] DataGridView set column cell Combobox

问题描述

我一样，在DataGridView的表：

 名称钱
 --------- ---- 
嗨100 //此处的组合框成员{} 10,30,80,100选择
文30 //这里与成员{} 10,30,80,100选择
组合框 

我想从组合框更改列钱值

我试着用这个，但不知道更多：

  DataTable的DT =新的DataTable（）; 
 dt.Columns.Add（名，typeof运算（字符串））; 
 dt.Columns.Add（钱途的typeof（字符串））; 
 dt.Rows.Add（新的对象[] {100}）; 
 dt.Rows.Add（新的对象[] {文，30}）; 
 
 DataGridViewComboBoxColumn列=新DataGridViewComboBoxColumn（）; 
变种list11 =新的List<串GT;（）{10，30，80，100}; 
 column.DataSource = list11; 
 column.ValueMember =钱; 
 dataGridView1.Columns.Add（列）; 
  

解决方案

试试这个

  dataGridView1.AutoGenerateColumns = FALSE; 
 
 DataTable的DT =新的DataTable（）; 
 dt.Columns.Add（名，typeof运算（字符串））; 
 dt.Columns.Add（钱途的typeof（字符串））; 
 dt.Rows.Add（新的对象[] {100}）; 
 dt.Rows.Add（新的对象[] {文，30}）; 
 
 DataGridViewComboBoxColumn钱=新DataGridViewComboBoxColumn（）; 
变种list11 =新的List<串GT;（）{10，30，80，100}; 
 money.DataSource = list11; 
 money.HeaderText =钱; 
 money.DataPropertyName =钱; 
 
 DataGridViewTextBoxColumn名=新DataGridViewTextBoxColumn（）; 
 name.HeaderText =姓名; 
 name.DataPropertyName =姓名; 
 
 dataGridView1.DataSource = DT; 
 dataGridView1.Columns.AddRange（姓名，钱）; 
  

只要使用 DataPropertyName 而不是 ValueMember

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); 

解决方案

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
