如何在 DataGridView 中建议追加 ComboBox? [英] How to Suggest Append ComboBox in DataGridView?

问题描述

我在 c# Windows 窗体应用程序中有一个 ComboBox，我已将 AutoCompleteMode 设置为 SuggestAppend，并且文本会自动附加到输入中(图 1).

I have a ComboBox in a c# Windows forms application where I have set AutoCompleteMode to SuggestAppend, and the text is automatically appended to the input (Fig 1).

但是如果我在 DataGridView ComboBox 中将 AutoCompleteMode 设置为 SuggestAppend，它不会附加文本(图 2).

But if I set AutoCompleteMode to SuggestAppend in a DataGridView ComboBox it does not append the text (Fig 2).

如何在 datagridview 组合框中启用 SuggestAppend?

推荐答案

你会认为你会像普通的 ComboBox 那样做:

You'd think you'd do it just like the normal ComboBox:

this.comboBox1.AutoCompleteCustomSource = new AutoCompleteStringCollection();
this.comboBox1.AutoCompleteCustomSource.AddRange(new string[] { "Good night", "Good evening", "Good", "All Good", "I'm Good" });
this.comboBox1.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
this.comboBox1.AutoCompleteSource = AutoCompleteSource.CustomSource;

预期结果:

事实证明，你可以！但是，一旦您离开单元格，所选的选项就不会保留.我发现您必须更改如何添加下拉选项以及如何获取它们:

As it turns out, you can! But the selected option won't persist once you leave the cell. I found you have to change how you add the drop-down options and how you source them:

public Form1()
{
  InitializeComponent();
  DataGridViewComboBoxColumn cc = new DataGridViewComboBoxColumn();
  cc.Name = "Combo";
  cc.Items.AddRange(new string[] { "Good night", "Good evening", "Good", "All Good", "I'm Good" });
  this.dataGridView1.Columns.Add(cc);
}

private void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
  ComboBox box = e.Control as ComboBox;
  if (box != null)
  {
    box.DropDownStyle = ComboBoxStyle.DropDown;
    box.AutoCompleteSource = AutoCompleteSource.ListItems;
    box.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
  }
}

这将为您提供所需的结果:
