Problem combining the samples

The samples you posted are very useful especially to new programmers in vb.net like me. I learn so many things on how to manipulate datagrid. But when I combine some of the samples I can''t make it run properly. I want the combination of these samples into one datagrid: Combanation #1 1. Disable edit on some of the column 2. checkbox - enabled column 3. pushbutton - enabled column 4. text on the rowheader. 5. number formatting all should be right justified with 2 decimal places Combination #2 1. unbound column which automatically computes totals. 2. number formatting all should be right justified with 2 decimal places Can you help me how to get all of these on one datagrid?
