Call a button on a C# form through usercontrol

Question

I\'ve created a user control with some buttons. When you click a button in the UserControl the BackColor of the button changes:

 private void button1(object send         


        

Answer 1

i fixed it like this;

control:

public delegate void ColorChangeEventHandler();

public partial class myControl: UserControl
{


    public event ColorChangeEventHandler ColorChanged;

    private void OnColorChange()
    {
        if(ColorChanged != null)
        {
            ColorChanged.Invoke();
        }
    }

    public speelRij()
    {
        InitializeComponent();
    }

  private void Button1_Click(object sender, EventArgs e)
    {
        OnColorChange();
        Control ctrl = ((Control)sender);
        switch (ctrl.BackColor.Name)
        {
            case "Crimson": ctrl.BackColor = Color.Blue; break;
            case "Green": ctrl.BackColor = Color.Orange; break;
            case "Orange": ctrl.BackColor = Color.Crimson; break;
            case "Blue": ctrl.BackColor = Color.Green; break;
            default: ctrl.BackColor = Color.Crimson; break;
        }

form:

 public myForm()
    {
        InitializeComponent();
        myControl1.ColorChanged += () => { Button1.Enabled = true;};
    }
