如何建议在DataGridView中附加ComboBox？ [英] How to Suggest Append ComboBox in DataGridView?

问题描述

我有一个 ComboBox 在 c＃ Windows窗体应用程序中，我已经设置了 AutoCompleteMode to SuggestAppend ，文字会自动附加到输入（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).

但是如果将 AutoCompleteMode 设置为在 DataGridView ComboBox c>它不附加文本（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

d认为你会像普通的 ComboBox 一样做：

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，离开单元格后，选定的选项将不会持续。我发现你必须更改你如何添加下拉选项以及如何来源：

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：
