我有combobox1和comboox2,在combobox1中,我的元素是A,B,C和组合框2 1,2,3,4,5,6 ......
A related 1,2,3 and B related 3,4 and C related 5,6.
When I choose "A" I want to see just 1,2,3 ; when select "B" just 3,4 etc.
我怎么能想象呢?
我试图在选定的索引中更改,但我没有

试试这个,做一个这样的课:
public class Data
{
public string Name { get; set; }
public List<int> Values { get; set; }
}
然后在你的表单中有一个这样的变量:
private List<Data> data = new List<Data>
{
new Data{Name="A",Values=new List<int>{1,2,3}},
new Data{Name="B",Values=new List<int>{4,5}},
new Data{Name="C",Values=new List<int>{6,7}},
};
然后在表单的构造函数中:
comboBox1.DisplayMember = "Name";
comboBox1.DataSource = data;
comboBox1.SelectedIndex = 0;
然后在combobox1的selectedindex更改事件中执行如下操作:
private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
int index = comboBox1.SelectedIndex;
comboBox2.DataSource = data[index].Values;
}
它应该有用。
