I have a TextBox for input from user. The preset text is like "Please input here".
When user clicks the TextBox, the text will be erased (ie. TextBox.text="" when clicked).
Then users can input text there.
However, when click again, the text will be erased again and this goes on.
How to make the 1st Click to erase the preset text but the following clicks to point at the desired text location?
