C#dataGridView中输入框自动提示、自动完成、自动补全功能

dataGridView像Textbox一样出现下拉列表的样式；具体实现方法如下：

1、在dataGridView的EditingControlShowing事件中添加如下代码，目的是为了将e.Control转为TextBox。

  private void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
        {
            DataGridViewTextBoxEditingControl editingControl = e.Control as DataGridViewTextBoxEditingControl;
            editingControl.AutoCompleteCustomSource = source;
            editingControl.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
            editingControl.AutoCompleteSource = AutoCompleteSource.CustomSource;
        }

2、接下来就可以像Textbox一样实现输入框自动提示、自动完成、自动补全功能了~~
