Remarks
ASPxGridView supports conditional formatting, i.e., automatically applies cell formatting based on the specified rules. The ASPxGridView.FormatConditions property provides access to a collection of rules which are represented by the GridFormatConditionBase class descendants.
Use the GridViewFormatConditionColorScale object to create a format condition allowing you to color grid cells. The conditional formatting is determined for the column specified by the GridFormatConditionBase.FieldName property. By default, the formatting is applied to the same column. However, you can specify the column to which the formatting will be applied using the GridViewFormatConditionColorScale.ShowInColumn property. The format (color scale) can be specified by the GridFormatConditionColorScale.Format property. If the GridFormatConditionColorScale.Format property is set to Custom, you can specify custom colors for a scale by using the GridFormatConditionColorScale.MinimumColor, GridFormatConditionColorScale.MiddleColor (optional), and GridFormatConditionColorScale.MaximumColor properties.
