嗨
我有一个项目，我有一个compobox，在compobox中，我的数据库中有数据表格.

我使用此compobox插入到另一个表中，但是我不希望选择的值是我想要的隐藏值(换句话说，在compobox中，显示的单词是"Name"，但我想插入"ID" ;)

谢谢

推荐答案

Video video = myComboBox.SelectedItem as Video;
if (video != null)
    {
    Console.WriteLine("{0}:{1}", video.Id, video.Title);
    }

// Set the name as the property to be displayed and the ID as the value to be returned when a row is selected.  
// Here these are properties; if we were binding to a database table or query these could be column names.
ComboBox1.DisplayMember = "Name";
ComboBox1.ValueMember = "ID";

// After selection
// this will give you the inner 'hidden' value
textBox1.Text = ComboBox1.SelectedValue.ToString();
// If you also wanted to get the displayed text
// the SelectedItem item property:
// string s = ((USState)ComboBox1.SelectedItem).Name;
