With List
Documentation
This demo shows how to filter data in the List using the FilterBuilder widget. Note that the DataSource does not support the "between" operation. Call the getFilterExpression() method to convert it into DataSource-compatible operations.
Feel free to share demo-related thoughts here.
If you have technical questions, please create a support ticket in the DevExpress Support Center.
