Question

我有datagridview和带有单元格DataGridViewComboboxCell的列。 DisplayStyle设置为Nothing。当我开始输入此单元格时，将其样式更改为组合框。我无法提供我的tekst，因为根据我提供的文本搜索单元格。我想将它的样式改为comboboxlist，因为它在组合框中。我有空字段，我可以输入我的文字。在组合框中可以做到这一点吗？

你可以这样试试..

    public void ComboList1()
    {
        DataGridViewComboBoxColumn combo1 = new DataGridViewComboBoxColumn();
        combo1.HeaderText = "Country";
        combo1.Items.Add("Antarctica");
        combo1.Items.Add("Belgium");
        combo1.Items.Add("Canada");
        combo1.Items.Add("Finland");
        combo1.Items.Add("Albania");
        combo1.Items.Add("India");
        combo1.Items.Add("Barbados");
        dataGridView1.Columns.Add(combo1);
    } 
    public void ComboList2()
    {
        DataGridViewComboBoxColumn combo2 = new DataGridViewComboBoxColumn();
        combo2.HeaderText = "Types of Jobs";
        combo2.Items.Add("Accounting");
        combo2.Items.Add("HR");
        combo2.Items.Add("Finance");
        combo2.Items.Add("Transportation");
        combo2.Items.Add("Testing");
        dataGridView1.Columns.Add(combo2);
    }

从Form Constructor中调用这两个方法。

现在单击DataGridView并生成EditingControlShowing事件并在其中编写以下代码：

        if (e.Control is DataGridViewComboBoxEditingControl)
        {
            ((ComboBox)e.Control).DropDownStyle = ComboBoxStyle.DropDown;
            ((ComboBox)e.Control).AutoCompleteSource = AutoCompleteSource.ListItems;
            ((ComboBox)e.Control).AutoCompleteMode = System.Windows.Forms.AutoCompleteMode.Suggest;
        }

或尝试这样

private string[] list;
private DataSet ds;

public frmMain()
{
  InitializeComponent();
  ds = this.GetDataSet("SELECT deptName from empDept", "empDept");
  list = new string[ds.Tables[0].Rows.Count];
  comboBox1.AutoCompleteCustomSource.AddRange(list);
  comboBox1.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
  comboBox1.AutoCompleteSource = AutoCompleteSource.ListItems;
}


private void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
  if (e.Control is ComboBox)
  {
    ComboBox cb = e.Control as ComboBox;
    cb.DropDownStyle = ComboBoxStyle.DropDown;

  }
}

如何使用DisplayStyle ComboBox List创建组合框？
