I have a column in the grid which is a DropDownList with AutoComplete. When I type in the cell and hit tab with an invalid value from the dropdown the cell becomes red then I go back by typing this time a valid one and select it from the dropdown list but when I hit tab with the valid value the cell remains in red. Why ? Should I perform a special action to remove the redness of the cell since the value is valid ?
The event CellDataError was used and had the background color changed there. I managed to use this event to avoid having the cell in red when the value is not found from the list. It works.
