You need to remove the "normal" textbox and replace it with your own class textbox. In this class Click method you would have something like:

if type('this.parent.parent.name')='C' and lower(this.parent.baseclass) = 'column'
   this.parent.parent.Click(this) && Assuming your grid class has parameters in Click method
endif

See FAQ by Mike Helland about adding controls in Grid on the fly.
