Mike,

Yes, it is somewhat clearer. Thanks for your patience. Now, what code changes do I have to make to have the double click fire the grid and not the text box?

>If you put a grid on a form, in order to add things like CheckBoxes, Combos, or change code in the default TB's you must adjust the ColumnCount from the default -1 to a number. THat will create the columns along with the modifiable Headers and TextBoxes for you. Usually I build my columns at run-time and leave columncount at -1 in designtime, thus I would have to find another way (like adding a TB class at run-time as well). Is that clearer?
