You go to the TextBox Properties/Events Icon/Focus/Enter and you give
the event a name like Textbox1_GotFocus or prefix it with whatever the
name of the textbox is. In the event, you call the TextboxHighlight
routine, giving it the Textbox control.

You can de-select the highlight by setting SelectionLength = 0


private void TextBox1_GotFocus(object sender, EventArgs e)
{
TextboxHighlight(textBox1);

}

private void TextboxHighlight(TextBox cntrl)
{
int ilen = cntrl.Text.Length;
cntrl.SelectionLength = ilen;
}


Then all you have to do is Textbox1.Focus, and if there is text in the
Textbox, it's going to be highlighted.

In addition to the other reply, note that 'Focus' will fail if the form is
not yet visible. You may want to use 'Select' instead.
