之前没弄明白ComboBox还可以这样用。
先建一个ComboBox子项类,然后可以获取该项类做一些判断,关键是要重写ToString()方法。
public class ComboItem { public string text; public string value; public override string ToString() { return text; } }
添加到ComboBox中:
private void Form1_Load(object sender, EventArgs e) { string[] strtextarr = { "A", "B", "C" }; string[] strvaluearr = { "1", "2", "3" }; int intcount = strtextarr.Length; for (int i = 0; i < intcount; i++) { ComboItem item = new ComboItem(); item.text = strtextarr[i]; item.value = strvaluearr[i]; this.comboBox1.Items.Add(item); if (strvaluearr[i] == "1") this.comboBox1.SelectedItem = item; } }
在ComboBox选择事件中显示选择值到TextBox中:
private void comboBox1_SelectedIndexChanged(object sender, EventArgs e) { ComboItem item = (ComboItem)this.comboBox1.SelectedItem; this.textBox1.Text = item.value; }
