New Line in Text Box

[Richard Divakar]

Hi,
I have a method which displays 'Hello'. Every time I call the method, it needs to display 'Hello' in a new line of the text box. I'm not able to do that. I only get one 'Hello' which happens to be the third called method's result. How can I get 'Hello' 3 times, in different lines in the text box when I call my method 3 times.
Example:

myMethod("Hello", 5==5);
myMethod("Hello", 5==5);
myMethod("Hello", 5==5);
 
private void myMethod(string p, bool p_2)
{
  textBox1.Text = (p + p_2);
}
 

Thank You,
Regards..

There's a couple things you need to do...

For starters, you're always assigning to the Text property of your textbox with a new value. This is going to overwrite it every time it's called. What you need to do is add to the textbox.

myTextBox.Text += "Text to append";

Now, you also need to set your textbox to a multiline textbox. To do this, set it's Multiline property to true (either in the designer or in code).

Finally, when you append your text, you need to put a line separator between your lines. The easiest way to do this is to insert an Environment.Newline before you append to your textbox. For example...

public void AppendTextToTextBox(TextBox theTb, string text)
{
  if (theTb != null)
  {
    if (theTb.Text != "") theTb.Text += Environment.NewLine;
    theTb.Text += text;
  }
}

Or something to that effect.
