Creating Event for Multiple Forms

Anonymous User 1877 30 Jan 2014

I have tried a bunch of different things, so obviously I am now stuck... I have created a form, it has a button on it - that when clicked creates a new form. I can click away and create multiple forms this way. What I would like and cannot get to work is to have the main form have a second button on it - that when clicked will change all of the background colors on the secondary forms.

Hi Samuel,

In your parent form do something like this.

private event Action<Color> ChangeColor;
private void CreateAndShowForm()
{
    var form2 = new Form2();
    ChangeColor +=form2.changeColor;
    /*do other stuff to show form*/
}
private void button1_Click(object sender, EventArgs e)
{
   
ChangeColor(Color.Red);
}
In the child forms
public void changeColor(Color obj)
{
    /*change background color*/
}
