IBindingRangeValueConverter Interface

An interface that allows you to convert cell values to custom objects and back.

Namespace: DevExpress.Spreadsheet

Assembly: DevExpress.Spreadsheet.v22.1.Core.dll


public interface IBindingRangeValueConverter


A custom converter that exposes the IBindingRangeValueConverter interface can be specified using the DataSourceOptionsBase.CellValueConverter property.


This code snippet contains the code of the converter which provides the IBindingRangeValueConverter.TryConvertFromObject method used to convert fields of a custom WeatherReport object for proper display in a worksheet and the IBindingRangeValueConverter.ConvertToObject method for storing cell values in the fields of a custom object.

public class MyWeatherConverter : IBindingRangeValueConverter {
    public object ConvertToObject(CellValue value, Type requiredType, int columnIndex) {
        if (requiredType == typeof(DateTime))
            return value.DateTimeValue;
        if (requiredType == typeof(Weather)) {
            if (requiredType == typeof(Weather)) {
                Weather w;
                if (Enum.TryParse(value.TextValue, out w)) return w;
                return Weather.Undefined;
                return value.TextValue;
        if (requiredType == typeof(List<HourlyReport>))
            return new List<HourlyReport>();
        return value.TextValue;
    public CellValue TryConvertFromObject(object value) {
        if (value is DateTime) {
            return ((DateTime)value).ToString("MMM-dd");
        if (value is Weather) {
            return value.ToString();
        if (value is List<HourlyReport>) {
            var hourly = (List<HourlyReport>)value;
            if (hourly.Count == 0) return "Undefined";
            var high = hourly
                .OrderByDescending(p => p.Temperature)
            var low = hourly
                .OrderBy(p => p.Temperature)
            return String.Format("High - {0}, Low - {1}", high, low);

        return CellValue.TryCreateFromObject(value);
