创建自定义datagridview的列类型

Question

我只是创建一个自定义控件，我希望此控件实现到datagridview的列。

但是如何？ 可能吗？

例如，我要添加“ DataGridViewCustomTextBoxColumn”之类的列类型

这是我当前的代码。

 private void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
    {    
        if (dataGridView1.CurrentCell.ColumnIndex == 0)
        {

            Connection.ConnectionClose();
            Connection.ConnectionOpen();

            var source = new List<string>();
            string queryItem = "SELECT * FROM ITEM ";              

            Connection.command = new OleDbCommand(queryItem, Connection.conn);
            Connection.command.CommandType = CommandType.Text;
            AutoCompleteStringCollection kode = new AutoCompleteStringCollection();

            reader = Connection.command.ExecuteReader();

            if (reader.HasRows == true)
            {
                while (reader.Read())
                {
                    //kode.Add(reader["code"].ToString());
                    source.Add(reader["code"].ToString());
                }
            }
            else
            {
                MessageBox.Show("Data not Found");
            }
            reader.Close();
            //ComboBox txtBusID = e.Control as ComboBox;
            TextBox kodeTxt = e.Control as TextBox;
            if (kodeTxt != null)
            {
                kodeTxt.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
                kodeTxt.AutoCompleteCustomSource = kode;
                kodeTxt.AutoCompleteSource = AutoCompleteSource.CustomSource;
            }

        }
  }

我试过的..像这样。

 AutoCompleteTextBoxSample.AutoCompleteTextbox kodeTxt = e.Control as AutoCompleteTextBoxSample.AutoCompleteTextbox;
                if (kodeTxt != null)
                {
                    kodeTxt.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
                    kodeTxt.AutoCompleteCustomSource = source;
                    kodeTxt.AutoCompleteSource = AutoCompleteSource.CustomSource;
                }

然后我的自动填充功能不再起作用

我想要的就是这样。

我将使用模板字段，如此处所述： https : //msdn.microsoft.com/zh-cn/library/bb288032.aspx

模板字段之一将是您的自定义控件。

这将涉及编写代码，而不是使用GUI。
