controlling another button in runtime....

Question

Hello there...

I have created two buttons with runtime control:

private void Form1_Load(object sender, EventArgs e)
        {
           for(int i=0;i<2;i++)
           {
            Button btn = new Button();
            btn.Size = new Size(80, 80);
            btn.Name = "deneme" + i;

            btn.Left = 80;
            btn.Top = i * 90;

            this.Controls.Add(btn);
            btn.Click += new EventHandler(btn_Click);

           }
        }
        void btn_Click(object sender, EventArgs e)
        {
            Button gonderen = (Button)sender;
            gonderen.BackColor = Color.Blue;
        }private void Form1_Load(object sender, EventArgs e)
        {
           for(int i=0;i<2;i++)
           {
            Button btn = new Button();
            btn.Size = new Size(80, 80);
            btn.Name = "deneme" + i;

            btn.Left = 80;
            btn.Top = i * 90;

            this.Controls.Add(btn);
            btn.Click += new EventHandler(btn_Click);

           }
        }
        void btn_Click(object sender, EventArgs e)
        {
            Button gonderen = (Button)sender;
            gonderen.BackColor = Color.Blue;
        }

There are two buttons created in the form...

When I click one of the button, its color turns to blue...

My aim is, when I click one of the button, I want to change the color of the other button.

How could I accomplish that....

Try this: void btn_Click(object sender EventArgs e) { Button gonderen = (Button)sender; gonderen.BackColor = Color.Blue; // if still want it to be blue string name = gonderen.Name; if (name == deneme0) { this.Controls[deneme1].BackColor = Color.Green; // say } else if (name == deneme1) { this.Controls[deneme0].BackColor = Color.Green; // say } }
