Thank you for contacting us. In order to achieve the desired behavior you should handle the SelectedIndexChanged
event and set a new filter expression to the column that corresponds to the current RadComboBox. If you have encountered any issues assigning filter expressions please, refer to the this article
. It provides examples how to set filter expressions programmatically and also how to assign filters for multiple columns. Please, note that in order to apply a filter the EnableFiltering
property of RadGridView should be set to true
. Another important point in your case is that you should bind each RadComboBox to a different BindingSource. I hope this is helpful. If you have further question, do not hesitate to contact me back.
