Built for web applications that require ad-hoc query capabilities, the DevExpress ASP.NET Grid View (ASPxGridView) 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 displayed at the bottom of the grid.
The following properties (available through the SettingsFilterControl property) allow you to customize Filter Control functionality.
- The ViewMode property specifies how a filter expression is displayed in the Filter Control: either in the visual representation only, or in the visual representation and text filter expression editor.
- The AllowHierarchicalColumns property specifies if the Filter Control can display hierarchical columns. The max hierarchy depth level can be limited by using the MaxHierarchyDepth property.
- The ShowAllDataSourceColumns property specifies which columns are visible in the Filter Control: all data source columns or only the columns that are visible in the grid.
