This demo demonstrates all field editors that RadFilter presents by default:

  • RadFilterBooleanFieldEditor - this denotes a Boolean field. For a Boolean field, the filter list options are limited to EqualTo, NotEqualTo, IsNull and NotIsNull, followed by a checkbox, which would hold the true/false filter value, depending on its checked state.
  • RadFilterNumericFieldEditor - denotes a numeric field. It has more Filter options than the Boolean field, but the options are still limited to a numeric input - for example GreaterThan and LessThan. The input control, which is rendered is a numeric one, which limits the user input to numeric values only.
  • RadFilterTextFieldEditor - this field accepts any type of user input - alphabetical and numeric. It renders a standard textbox, which does not pose any restrictions on the user input. This filter type has the largest array of filter options.
  • RadFilterDateFieldEditor - this field allows the construction of a filter targeting dates. It renders a picker or date input control which facilitates the selection of a date\time, and validates the user input, to ensure that a valid date is passed as the filter value. Depending on the PickerType value the current filed editor instance will render RadDatePicker, RadDateTimePicker, RadTimePicker or RadDateInput.
  • RadFilterDropDownEditor - Represents an editor for populating predefined items to be filtered using a drop down control.
  • RadFilterMaskedTextBoxEditor - Represents an editor for filtering values using a RadMaskedTextBox control.

Another features enabled for the RadFilter in this demo: adding filter expressions dynamically, building filter expressions manually and reducing filter menu options.
