This class is used to instantiate a filter which can be applied to the number type values. It helps to filter out the data based on the specified numeric range. The listing below provides the details about different options that can be set for the filter using this class.

• Get or set the name of the data item property to which the current filter applies using the PropertyName property.
• Set the header text of the filter using the HeaderText property and determine its visibility with the help of ShowHeader property.
• Expand/Collapse the filter with the help of Expanded property.
• The Maximum and Minimum properties are used to set the minimum and maximum values for the filtering numeric range.
• Get or set the current lower/upper magnitude of the range with the help of LowerValue and UpperValue properties.
• Display/Hide the filter editors using the EditorsVisible property and set their type to TextBox/SpinEditor using the EditorsType property.
• Determine the visibility of the range slider using the SliderVisible property.
• The Increment property lets you specify the amount to increment/decrement from the filter value, when using the up/down buttons of the editors or up/down keys or mouse.
• Get or set the number of fractional digits that can appear in the filter value with the help of Digits property.
• Retrieve the current filter expression with the help of Expression property.
• The IsApplied property can be used to find whether the current filter is applied or not.
