datagridview的数据源与和ComboBox [英] datagridview with datasource and combobox

问题描述

我有一个连接到它的数据源中的DataGridView制成的自定义数据表：

数据表：
0 =字典
1 =串
2 =字符串

在DataGridView是可编辑的，但是，对于列0我需要显示的组合框而不是文本字段。我如何去实现这个

 内部字典< INT，串> products_list =新词典< INT，串>（）; 
 products_list.Add（0，试验产品1）; 
 products_list.Add（1，试验产品2）; 
 
 
 lines.Columns.Add（新的DataColumn（产品，products_list.GetType（）））; 
 lines.Columns.Add（新的DataColumn（数量的typeof（INT）））; 
 lines.Columns.Add（新的DataColumn（说明中的typeof（字符串）））; 
 
 dgvQuoteLines.DataSource =线; 
 dgvQuoteLines.Columns [0] =。可见假的; 
  

* UPDATE *
现在我已成功地添加组合框到DataGridView但可悲的是数据源不工作

  DataGridViewComboBoxColumn colbox =新DataGridViewComboBoxColumn（）！; 
 colbox.DataPropertyName =0; 
 dgvQuoteLines.Columns.Add（colbox）;   

解决方案

我想这是你想要的>

  DataGridViewComboBoxColumn colbox =新DataGridViewComboBoxColumn（）; 
 colbox.DataSource = products_list.ToList（）; 
 colbox.ValueMember =键; 
 colbox.DisplayMember =值; 
 dgvQuoteLines.Columns.Add（colbox）; 
  

I have a datagridview with a datasource attached to it made of a custom datatable:

DataTable: 0 = Dictionary 1 = string 2 = string

the datagridview is editable, however for column 0 I need to show a combobox instead of a text field. How do I go about achieving this?

internal Dictionary<int, string> products_list = new Dictionary<int, string>();
products_list.Add(0, "Test Product 1");
products_list.Add(1, "Test Product 2");


lines.Columns.Add(new DataColumn("Product", products_list.GetType()));
lines.Columns.Add(new DataColumn("QTY", typeof(int)));
lines.Columns.Add(new DataColumn("Description", typeof(string)));

dgvQuoteLines.DataSource = lines;
dgvQuoteLines.Columns[0].Visible = false;

* UPDATE * I have now managed to add the combobox to the datagridview but sadly the datasource isn't working!

DataGridViewComboBoxColumn colbox = new DataGridViewComboBoxColumn();
colbox.DataPropertyName = "0";
dgvQuoteLines.Columns.Add(colbox);

解决方案

I think this is what you want:

DataGridViewComboBoxColumn colbox = new DataGridViewComboBoxColumn();
colbox.DataSource = products_list.ToList();
colbox.ValueMember = "Key";
colbox.DisplayMember = "Value";
dgvQuoteLines.Columns.Add( colbox );
