need help with c1truedbgrid?

hi,

i created a usercontrol that inherits the c1truedbgrid component. in my usercontrol i add a method called myAddColumn which when called adds a column to the grid, its parameters is the header and the detail of the column. the method works fine when its envoke in the form by pressing a button called "Add". but when i call it from another class which i created, that basically functions as a connection to the database, the column wont be added. can you solve this?

thanks
