ICellValueConverter Interface

A converter that converts custom objects to cell values and vice versa.

Namespace: DevExpress.Spreadsheet

Assembly: DevExpress.Spreadsheet.v21.1.Core.dll

Declaration

public interface ICellValueConverter

Example

To convert custom objects to cell values and vise versa, you can apply your own converters.

This example demonstrates how to convert a color object (Color) to a SpreadsheetControl-compatible cell value of the text type (CellValue) that corresponds to the color name. To do this, create a custom converter class that implements the ICellValueConverter interface, and call the CellValue.FromObject method with the color object and custom converter passed as parameters.

        Worksheet worksheet = workbook.Worksheets[0];
        Cell cell = worksheet.Cells["A1"];
        cell.FillColor = Color.Orange;
        cell.Value = CellValue.FromObject(cell.FillColor, new ColorToNameConverter());
        // ...
class ColorToNameConverter : ICellValueConverter {
    object ICellValueConverter.ConvertToObject(CellValue value) {
        return null;
    }
    CellValue ICellValueConverter.TryConvertFromObject(object value) {
        bool isColor = value.GetType() == typeof(Color);
        if (!isColor)
            return null;
        return ((Color)value).Name;
    }
}
