End-users can create filter criteria using visual representation (Visual tab) or by typing the criteria as text (Text tab). The content of the tabs is automatically synchronized. Note that the Text tab is disabled by default, and the Visual tab header is not displayed. Set the ASPxGridFilterControlSettings.ViewMode property to VisualAndText to enable them.
The operand type button allows end-users to switch a filter condition between two modes: comparing a field's value to a value; or comparing a field's value to another field's value. Button visibility is controlled by the ASPxGridFilterControlSettings.ShowOperandTypeButton property.
Visibility of Filter Operators
The filter control drop-down window displays different comparison operators based on the column data type. The table below lists comparison operator visibility for different column types.
