try DirectCast

itemWhse = DirectCast(e.Item.Cells(9).FindControl("lstWhse"), System.Web.UI.WebControls.DropDownList)

and make sure the control you are looking for inside that cell, remember index start with 0 (try 8 or 10)

DataGrid.EditCommand Event

Occurs when the Edit button is clicked for an item in the DataGrid control.
