The DevExpress ASP.NET Tree List (ASPxTreeList) Filter Control allows end-users to build complex filter criteria with an unlimited number of filter conditions and logical operators. You can activate the Filter Control by clicking the image or filter expression link contained in the Filter Bar at the bottom of the grid.

The Filter Bar displays the following elements:

  • Filter Check Box - Enables or temporarily disables the current filter.
  • Filter Image - Click this image to invoke the Filter Builder.
  • Filter Expression Link - A string representation of the currently applied filter criteria. A click on this link invokes the Filter Builder.
  • Clear Command - Clears the current filter.

The control's ViewMode property specifies how to display a filter expression in the Filter Control: either in the visual representation only or the visual representation and text filter expression editor.
