I would like to change the color of the popup background when using a DatagridComboboxColumn in the WPF Toolkit datagrid. I ve edited the Template for a normal Combobox and it works great for selected item and other properties but the background stays white. I ve used Snoop to do some research into the template and it claims that the DropdownBorder s background is set by the parent template but I can t figure out which template that is.
Any ideas?
