datagridview with datasource and combobox
提问by Neo
I have a datagridview with a datasource attached to it made of a custom datatable:
我有一个 datagridview，其中附加了一个由自定义数据表组成的数据源：
DataTable: 0 = Dictionary 1 = string 2 = string
数据表：0 = 字典 1 = 字符串 2 = 字符串
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?
datagridview 是可编辑的，但是对于第 0 列，我需要显示组合框而不是文本字段。我该如何实现这一目标？
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!
* 更新 *我现在已经设法将组合框添加到 datagridview 但遗憾的是数据源不起作用！
DataGridViewComboBoxColumn colbox = new DataGridViewComboBoxColumn();
colbox.DataPropertyName = "0";
dgvQuoteLines.Columns.Add(colbox);

I think this is what you want:
我认为这就是你想要的：
DataGridViewComboBoxColumn colbox = new DataGridViewComboBoxColumn();
colbox.DataSource = products_list.ToList();
colbox.ValueMember = "Key";
colbox.DisplayMember = "Value";
dgvQuoteLines.Columns.Add( colbox );
Look at the DataGridViewComboBoxColumnclass.
回答by Derek
colBox.DataSource = products_list.Values.ToList();
colBox.DataSource = products_list.Values.ToList();

What do you want to show up in the combobox?
你想在组合框中显示什么？
