Two comboboxs: One as Father and other as Children

Israel

Hi!

I need to make two comboboxs (cmbxFather and cmbxChildren) "talking". What I want to see?

In the cmbxFather there is three Father's names: Steve, Paul e Greg. Then each one have children (for example, Steve = 4 children, Paul = 2 children, Greg = 1 child).

When you select for example the first name Steve, the cmbxChildren loads those 4 children and so one for others Fathers' s name when selected in cmbxFather.

I am not sure if I am clear?

Thanx,

Israel

Here's some basic code to do something like that in Windows Forms:

public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private string[] fathers;
private Dictionary> children;

private void Form1_Load(object sender, EventArgs e)
{
fathers = new string[]{ "Steve", "Paul", "Greg" };
children = new Dictionary>();
children.Add("Steve", new List{"Peter", "Jane", "David", "Esther"});
children.Add("Paul", new List{"Don", "Fred"});
children.Add("Greg", new List { "Dawn" });
cmbxFather.DataSource = fathers;
cmbxFather.SelectedIndex = 0;
}

private void cmbxFather_SelectedIndexChanged(object sender, EventArgs e)
{
cmbxChildren.DataSource = children[cmbxFather.SelectedItem.ToString()];
}
}
