trying to get spin edit and edit buttons to work

I am just starting to try TadvstringGrid and have written a simple program to figure out how to use its features. somethings worked right away but the following are resisting:

Spin edit field: when i edit the field I can use the up and down arrows to change the value but the up and down arrow icon is not visible.

EditBtn: seems to act like a simple edit field. No button is displayed.

The asgdemo project (sample 4) runs and displays the spin edits correctly and I have tried to copy the relevant parts of the code. What might I have left out that would cause these not to display?
