comboBox和textBox支持内置的搜索提示功能, 在form的InitializeComponent()中添加如下语句: //将数据添加到搜索范围 this.comboBox1.AutoCompleteCustomSource.AddRange(new string[] { "10.152.154.89", "10.152.154.90", "10.152.252.10", "10.152.252.11" }); 默认是None,还有Append,和SuggestAppend属性,除了默认的None都可以实现搜索提示的功能 this.comboBox1.AutoCompleteMode = System.Windows.Forms.AutoCompleteMode.Suggest; this.comboBox1.AutoCompleteSource = System.Windows.Forms.AutoCompleteSource.CustomSource; 转自http://www.cnblogs.com/luomingui/archive/2010/03/17/1688188.html 但经过测试并不能实现真正的模糊查询,只能从左到右查询,所以还是得自己写一个: private void comboBox1_TextUpdate(object sender, EventArgs e) { ComboBox cbBox = (ComboBox)sender; List<string> listNew = new List<string>(); cbBox.Items.Clear(); foreach (var item in listCell) //已有数据 { if (item.Contains(cbBox.Text)) { listNew.Add(item); } } cbBox.Items.AddRange(listNew.ToArray()); cbBox.SelectionStart = cbBox.Text.Length; Cursor = Cursors.Default; cbBox.DroppedDown = true; }
