The DevExpress ASP.NET MVC Tree List (TreeListExtension) Filter Builder allows end-users to build complex filter criteria with an unlimited number of filter conditions and logical operators. You can activate the Filter Builder 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 extension's ViewMode property specifies how to display a filter expression in the Filter Builder: either in the visual representation only or the visual representation and text filter expression editor.
