Grid View - Filter Builder

The DevExpress MVC Grid View implements the built-in Filter Builder. You can use it to allow end-users to visually build complex filter criteria with an unlimited number of filter conditions, combined by logical operators.

End-users can open the Filter Builder popup window by clicking the image or filter expression link within a specific Filter Bar that can be displayed at the grid bottom. By default, the Filter Bar isn't displayed. You can use the Settings.ShowFilterBar property to control its display mode (Hidden, Visible, Auto).

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.

When the Filter Builder popup window is invoked, end-users are allowed to create and customize filter criteria as follows.

• Add/Remove Conditions
  To create and customize filter criteria, use the Add and Remove buttons.
• Change a Column in a Filter Condition
  To change a condition's column, invoke the column list and choose the required column.
• Change an Operator in a Filter Condition
  To change a condition's operator, invoke the operator list and choose the required operator.
• Edit a Condition's Value
  To edit a condition's value, click the operand value and type text. To discard changes to the value and close the active edit box, press ESC.
