The ASPxFilterControl is a stand-alone control that allows end-users to build filter criteria. It does not require any SQL syntax and doesn't have any limitations regarding the complexity of the filter conditions. With the ASPxFilterControl, you can construct any number of filter expressions, combined by any logical operator, and apply them to controls or to a data source.
The ASPxFilterControl provides multiple styles that allow you to customize the appearance of individual elements and manage the control's overall appearance. Each style property has a number of attributes that allow you to customize element appearance to the maximum extent allowed by web browsers. These attributes include: colors, fonts, borders, text attributes, etc.
Gets the style settings that define the criteria value appearance.
The filter expression obtained can be validated for completeness by using the IsFilterExpressionValid method, available both on the server and client sides. This method checks whether or not an end-user has entered all the required criteria values, and indicates whether or not it's safe to apply the expression.
You can define validation settings for each column separately. See the Validation topic to learn more.
