Hi João!

>Hi all,
>I have two questions about Grids.
>1 - Where i know...is the last column in Grid.

The grid's property ColumnCount.


>2 - I need to add or remove (one or more columns at run-time) at the end of the grid, but this columns need to have some code in one or two methods... any way to do that???

Here, if you need the methods in text object (and not in column), you can to create a class based in TextBox and after you put it in your new column.

I hope this helps you.
