Remarks

Range conditions allow you to apply formatting using a predefined set of value ranges and corresponding style settings. You can use a predefined set of colors/icons to apply formatting or use custom ranges and corresponding icons/colors.

To use a predefined set of colors/icons, pass the required FormatConditionRangeSetPredefinedType enumeration value to the FormatConditionRangeSet constructor or call the corresponding FormatConditionRangeSet.Generate method overload.
To use a predefined set of colors/icons and custom range boundaries, do the following.
To use custom range boundaries and the required style specified for each range, do the following.

Assign the resulting FormatConditionRangeSet object to the DashboardItemFormatRule.Condition property.

Example

Range conditions (FormatConditionRangeSet) allow you to use predefined or custom sets of icons/colors to apply conditional formatting to different ranges of values.

This example shows how to apply conditional formatting to Grid cells using a predefined set of icons. Click the Update Format Rule button to change the number of ranges, specify new range boundaries and customize icons corresponding to existing ranges.
