    Vijay,

    As per the update from the development team, Spread WPF does not support cell types, but as a workaround you may use Custom Drawing Object. However please note that if you use custom drawing object, then you would need to do a lot of things yourfelf in the code. You can find some sample code to implement a custom drawing object at the following link:

    So it’s been about 5 years since this thread. I’ve been able to follow examples in the forums to create my combo boxes for the correct cells, but I can’t find anywhere that shows how I can bind to the values in the cells where the combo boxes are. Is there any example that shows how to get and set those values for use in my combo box? Thank you!

    Hello Nathan,

    JFYI, SpreadSheet WPF does not support cell types. You need to create Custom Drawing Object for the same as:

    
       public class MyDrawingObjectProvider : IDrawingObjectProvider
        {
            public DrawingObject[] GetDrawingObjects(Worksheet sheet, int row, int column, int rowCount, int columnCount)
            {
                if (row == 1 && column == 1)
                {
                    return new ControlDrawingObject[] { new ControlDrawingObject(row, column, new ComboBox()) };
                }
                return sheet.GetDrawingObject(row, column, rowCount, columnCount);
            }
        }
    
        public class ControlDrawingObject : CustomDrawingObject
        {
            private ComboBox _rootElement;
            public ControlDrawingObject(int row, int col, ComboBox myCombo) : base(row, col) 
            { 
                _rootElement = new ComboBox();
                _rootElement.ItemsSource = Enum.GetValues(typeof(ProductType)); 
                this.ShowDrawingObjectOnly = true; }
            public override FrameworkElement RootElement
            {
                get { return _rootElement; }
            }
        }
    
    

    Please refer the attached sample for the same : SpreadComboBoxDemo.zip

    Best Regards,
