datagridview combobox cell c#
提问by santBart
My code:
我的代码：
DataGridViewComboBoxCell cell = new DataGridViewComboBoxCell();
DataTable data = new DataTable();
data.Columns.Add(new DataColumn("Value", typeof(string)));
data.Columns.Add(new DataColumn("Description", typeof(string)));
data.Rows.Add("5", "6");
data.Rows.Add("51", "26");
data.Rows.Add("531", "63");
cell.DataSource = data;
cell.ValueMember = "Value";
cell.DisplayMember = "Description";
cell.DisplayStyle = DataGridViewComboBoxDisplayStyle.ComboBox;
dataGridView1.Rows[0].Cells[0] = cell;
It displays combobox but can't select any value of it. Whats wrong
它显示组合框，但不能选择它的任何值。怎么了

You generally don't work with the individual cell types in the DataGridView. Instead you want to add a column of type DataGridViewComboBoxColumn.
您通常不使用DataGridView. 相反，您想添加一个类型为 的列DataGridViewComboBoxColumn。
So instead of your provided code you want something like:
因此，您想要的不是您提供的代码，而是：
var column = new DataGridViewComboBoxColumn();
DataTable data = new DataTable();
data.Columns.Add(new DataColumn("Value", typeof(string)));
data.Columns.Add(new DataColumn("Description", typeof(string)));
data.Rows.Add("5", "6");
data.Rows.Add("51", "26");
data.Rows.Add("531", "63");
column.DataSource = data;
column.ValueMember = "Value";
column.DisplayMember = "Description";
dataGridView1.Columns.Add(column);
For reference, the documentation on the DataGridViewCombobBoxCell is on MSDN here. You can also find information on the DataGridView in general there. Another very good reference is the DataGridViewFAQ.
作为参考，有关 DataGridViewCombobBoxCell 的文档位于 MSDN此处。您还可以在那里找到有关 DataGridView 的一般信息。另一个很好的参考是DataGridViewFAQ。
