>How to highlight a textbox automatically? I need this because I have a numeric input textbox where upon entering the value, the initial zero value always adds at the end of the value being inputted. I want the zero automatically deleted when entering the a value.

You can use SelectAll property of the textBox control. First create an Enter, Click, or DoubleClick Events that contains code like this:

if((double)textBox1.Value = 0.00){
    textBox1.SelectAll();
}
