Ed,

>> I didn't say it's hard, I said it's not easy :) It requeres at least to have this class... BTW, in my Input classes I created Inp_Grid with ability to change standard TextBox class to be my class in Run time. I have a question:

So, it's not necessary if I add new control under Text1 name, right?

assign it to the CurrentControl before deleting out the default textbox. Doing this makes it easy to grab any properties that were inherited when the initial textbox was added by default that I might want in the new grid object.

It's a little unclear for me... Do you mean, you want your new Text object (or it may be editbox, whatever) uses the same Font, Alignment, etc., as Standard Text1 in the Grid? Or what properties?

Thanks for these advices. I'll change my class this way.
