Filtering API
Documentation
The DataGrid widget ships with an integrated filtering API, allowing you apply filters in code. In this example, the grid’s filter function is called to filter data based on selections made within the drop-down menu above the DataGrid.
Feel free to share demo-related thoughts here.
If you have technical questions, please create a support ticket in the DevExpress Support Center.
Thank you!
