On ItemDataBound of the mastertable I am hiding the delete and edit columns for certains rows.
This part is working perfectly, except for when the detailtable is displayed. When the detailtable is displayed it rebinds the whole grid but does not call ItemDataBound for the mastertable so the delete and edit columns are displayed again.
I can remove the edit and delete buttons for the parentItem but not any of the other rows. How do I remove it from the other rows?

Hello mk,
Indeed, the ItemDataBound event handler is not raised on each page cycle. Thus, another option in your case would be to use the PreRender event handler, which is raised on each page cycle - there you can iterate through all the items in the grid, and hide/show the relevant cells.
I hope this suggestion helps.
