Question

I created a simple code here just to play around with C#. It has 3 buttons and 1 panel. If you click on the 2nd & 3rd button the panel height changes. Is that also possible to change the color?

For example, if I click on the 2nd button, I would like to have it as yellow and at the same time the height changes as well, and the same with 3rd button.

public partial class Form1 : Form
 {
public int heightPanel;

  public Form1()
    {
  InitializeComponent();
  heightPanel = panel1.Height;
    }

  private void button1_Click(object sender, EventArgs e)
    {
  panel1.Height = heightPanel;
    }

  private void button2_Click(object sender, EventArgs e)
    {
  panel1.Height = this.Height/2;
    }

  private void button3_Click(object sender, EventArgs e)
    {
  panel1.Height = this.Height - 150;
    }
  }

I have an idea but I don’t know where to put this. I think it would be something like this:

panel1.Height=this.BackColor.ToString();

Any inputs?

Response to reply

Yes, I would like to retain the 3 colors if I click in any of the button. I’m not sure if it’s possible. For ex:

my button1 =pink
button2=yellow
button3=green

If I click on the button 1 I’ll see the pink color, and if I click on the button2 I’ll see the pink and yellow.

Is that possible?

Answer 1

All you’d need to do would be to set the BackColor on a new line. For instance…

private void button2_Click(object sender, EventArgs e)
{
    panel1.Height = this.Height/2;
    panel1.BackColor = Color.Yellow;
}

private void button3_Click(object sender, EventArgs e)
{
    panel1.Height = this.Height - 150;
    panel1.BackColor = Color.Yellow;
}
