Hi Budianto,

Ok, here is another idea:

Either add a new property to your text class, called OldValue, or use Tag property, which is less convenient.

In GotFocus this.OldValue=this.Value
In Click
blank field (this.ControlSource)

In LostFocus:

if isBlank(this.value)
   this.value = this.OldValue
endif

This is of the top of my head and not tested.

I'm also not 100% sure, user would like to have nothing in the field, if it's clicked. What if he/she clicks by mistake and not with the intention of changing?

My first solution just selects everything in the textbox, so user can hit Del button and type anything he/she wants...
