Question

MY CODE:

namespace textbox { public partial class Form1 : Form { public Form1() { InitializeComponent(); }

    private void button2_Click(object sender, EventArgs e)
    {
        textBox1.Text = textBox1.Text + "2";


    }

    private void button1_Click(object sender, EventArgs e)
    {


        textBox1.Text = textBox2.Text += "1";

    }

    private void textBox2_TextChanged(object sender, EventArgs e)
    {

    }
}

}

Answer 1

In your button1_Click method, the textBox1.Text is attributed the result of concatenating "1" to textBox2.Text . I think this is the cause of your problem.
