Editable DropDown list in PropertyGrid with a not-listed value

[Alejandro]

Hello, support team.

I have an application with a PropertyGrid in C# with WinForms. In this PropertyGrid I need to display a drop-down list with a predefined value list, but I need to allow also the user be able to edit a not listed value.

Thank you in advance

Hello, Alejandro,

Thank you for writing.

RadPropertyGrid offers PropertyGridDropDownListEditor. More information about the build-in editors in RadPropertyGrid is available in the table here: Editors - RadPropertyGrid - Telerik UI for WinForms

The following KB article about how to use the PropertyGridDropDownListEditor: How to use RadDropDownList as editor in RadPropertyGrid

If you need to allow the users to edit items and non-existing value, then I would also recommend the following article: How to allow end-users to add custom items to PropertyGridDropDownListEditor - Telerik UI for WinForms

Please let me know if you have other questions.
