Call SelectedIndexChanged on ComboBox within User Control

Question

I am using .NET 4 and trying to create a CustomControl but when I add this CustomControl onto my Windows Form, I want to have access to the SelectedIndexChanged for the ComboBox within my User Control.

Basically, what I want is when the Combo Box triggers the Selected IndexChanged, it will run some code within the Windows Form.

Below is what I have so far.

public partial class CustomControl : UserControl

...

private void uiComboBox_SelectedIndexChanged(object sender, EventArgs e)
{

}

What is the best way to do what I want?

Any help will be much appreciated.

Answer 1

In my CustomControl class, I had added in the following code so the SelectedIndexChanged on the combox will be picked up by my Custom Control when added as a Control onto a Form.

    public event EventHandler SelectedCBIndexChanged;

    ...

    public CustomControl()
    {
        InitializeComponent();
        this.uiComboBox.SelectedIndexChanged += new System.EventHandler(this.uiComboox_SelectedIndexChanged);
    }


    protected void uiComboox_SelectedIndexChanged(object sender, EventArgs e)
    {
        if (SelectedCBIndexChanged != null)
            SelectedCBIndexChanged(sender, e);
    }

Then on the Form, I add my Custom Control and Enable the SelectedCBIndexChanged property in the Designer which creates the event/method below which is what I was after.

    private void customControl_SelectedCBIndexChanged(object sender, EventArgs e)
    {
        // Do what I want
    }  

I thought I'll leave this on here as it may help someone else in the future.
