I apologize if this isn't the correct area on the forum for this.
I have no clue how to do this. Any help would be greatly appreciated.
For the second part, it isn't very clear what you are asking for. You mention when a "single textbox is clicked" however, you don't typically "click" a TextBox, unless of course you are setting the focus onto that TextBox. Did you mean a Button? If so, can you provide more information about exactly what you are trying to achieve?
