See more: C# Windows string Text form
I have this code to write the string number1 into the textbox and a button (button2) to add "1" to the string number1 so it would appear in the textbox, but the textbox only shows the text inside it once i've pressed a button on it like a letter or Enter, any idea how to make it always show the string ?

ask questions if im not clear enough

private void textBox1_TextChanged(object sender, EventArgs e)
{
        textBox1.Text = number1.ToString();
}
private void button2_Click(object sender, EventArgs e)
{
    if(num1)
    {
        number1 = number1 + "1";
    }
    if (!num1)
    {
        number2 = number2 + "1";
    }
}

Solution 1

private void button2_Click(object sender, EventArgs e)
{
  if(num1)
  {
    number1 = number1 + "1";
    textBox1.Text = number1;   
  }
  else
  {
    number2 = number2 + "1";
    // textBox2.Text = number2;
  }
}

Should do the job (discard textBox1_TextChanged: you don't need it for this task).

The application is a calculator, just practicing some windows form stuff, the user has 0-9 buttons for each number and a textbox which displays the numbers. I need the textbox in there to display answers/numbers etc so I can't remove it I just need it to always display the string when it updates

I suggested you to remove the textbox1_TextChanged event handler, not the text box itself.

I don't understand :P (new to programming)
If I delete textBox1_TextChanged then it messes up the textbot

Who needs a calculator with buttons?

To see how a really useful calculator should work, take a look at my On-line Calculator.
