Hi David,
Here is the sample that adds label and combo box according to the values of one of the columns from the grid (we displayed the DropDownList and labels with respect to the values of the ''CategoryID'' )
I have added the combo box and label programmatically using templates please look in the following KB.
http://www.syncfusion.com/support/kb/grid/Default.aspx?ToDo=view&questId=373
In QuerCellStyleInfo event, we decided to show the respected control (label or combo box). We have loaded different values from datatable to combo box with respect to the value from the Grid. (The data''s used here are not relevant and done for sample purpose.).
We used item templates in this sample and let us know if you need the sample using edititemtemplate or any other specifications.
You can download the sample from here:

Please let me know if you have any queries.
Thanks,
