I looked through the Bug Tracker and did not see this as being known. When using a ComboBoxAdv with a datasource and the SelectedValue is retrieved in the SelectedValueChanged Event the old value is retrieved. It can be worked around by accessing the value through the SekectedItem property. Thanks for your product and support.

Thanks for your feedack on this issue. I have tested for this error here and observed that the SelectedValue returned currently selected value in the ComboBoxAdv and not the previous one - which is the right behavior. Please try this test sample attached here, and let me know if I have understood your requirements correctly. If not, I would appreciate if you could modify this sample accordingly, and send it back to us so that we could further investigate this issue. We appreciate your cooperation, and thanks for choosing Syncfusion products.
