The Grid View control implements a column header filter that displays a dropdown list of all unique values within a column. Set the ShowHeaderFilterButton to true to show header filter buttons for each data column. You can use the AllowHeaderFilter property to control the button visibility for a particular data column.

Users can enter text in the filter editor above the list to filter list items. To hide the filter editor, set the ShowHeaderFilterListBoxSearchUI property to false.

A column’s Mode property specifies the filter mode. You can set the following filter modes for each grid data column.

  • List – the dropdown window displays a regular list of items that allows users to select a single value.
  • CheckedList – the dropdown window displays a check box list that allows users to select multiple values.

Additionally, the grid control implements filter modes for specific column data types: DateRangeCalendar and DateRangePicker modes available for date columns; NumericRangePicker mode available for numeric columns. You can try these modes in the Range Header Filter demo.

You can handle the following events to customize the header filter items:

In this demo, the header filters of the Total and Quantity columns contain custom items.
