1. Add RadDropDowlList in form. 2. Open the items collection and add some items. 3. After that set the Selected property of one item to true and click OK. 4. You will see that the change is not saved. Workaround: Set the selected item at run time.
Hello,
I have reviewed this case using the latest Q4 2025 version (2025.4.1111) of the Telerik UI for WinForms suite, and the issue does not reproduce. The Selected property set at design time works as expected.
This is why I will move forward with closing this item and setting its status to "Declined" on our feedback portal, as the issue does not reproduce in the latest version. Please upgrade to the latest version to take advantage of the improvements in the RadDropDownList component.
If you have any other questions or concerns, please let me know. Thank you!
