Change button color when clicked (multiple clicks/colors)

button, c#, colors

Solution

Hi Temporary you can use below solution:

void btnEvent_click(object sender, EventArgs e)
{
    Control ctrl = ((Control)sender);
    switch (ctrl.BackColor.Name)
    {
        case "Red":
            ctrl.BackColor = Color.Yellow;
            break;
        case "Black":
            ctrl.BackColor = Color.White;
            break;
        case "White":
            ctrl.BackColor = Color.Red;
            break;
        case "Yellow":
            ctrl.BackColor = Color.Purple;
            break;
        default:
            ctrl.BackColor = Color.Red;
            break;
    }
}

I know there can be a better solution also, but meanwhile you can go with this...you can add more colors also in switch statment as required

Problem

I am trying to make a array of 8x8 buttons, and so far it works. Now I have stumbled upon a problem. I want the color of the button (backcolor) to change when it is clicked. And change to a different color when clicked again. This is my code so far: ``` namespace WindowsFormsApplication2 { public partial class Form1 : Form { Button[,] btn = new Button[8,8]; public Form1() { InitializeComponent(); for (int x = 0; x < btn.GetLength(0); x++) { for (int y = 0; y < btn.GetLength(1); y++) { btn[x,y] = new Button(); btn[x,y].SetBounds(40 * x, 40 * y, 40, 40); btn[x,y].Click += new EventHandler(this.btnEvent_click); Controls.Add(btn[x, y]); btn[x,y].BackColor = Color.Black; } } /* btn.Click += new EventHandler(this.btnEvent_click); btn[x,y].Text = Convert.ToString(x+","+y); Controls.Add(btn); btn[x,y].Click += new EventHandler(this.btnEvent_click); */ } private void form1_load(object sender, EventArgs e) { } void btnEvent_click(object sender, EventArgs e) { (Control)sender).BackColor = Color.Red; } } } ``` So far I can only change the color to red, and I've tried multiple if and for statements to change the color a second time. Could anyone help me out?
