You could use DynamicCurrentControl:
1. Add couple commandbuttons with specific captions (hopefully you need in few) to particular column.
2. Issue something like:
this.column3.dynamiccurrentcontrol="iif(table.number!=1,'Command1','Command2')"
in Grid event and set Column3.Sparse=.F.
In this example you will see either Command1 or Command2 (with different captions) depending on 'number' value.
