    some of our users complains about the fact that they need to click twice to edit a value in a PropertyGridDropDownListEditor.

    The first click generate and start the editor, the second to open the list.

    Is there a way to automatically open the list after the editor has been initialized?

    Hi Valerio,

    You can use the EditorInitialized event to show the popup. Here is the code:

    private void RadPropertyGrid1_EditorInitialized(object sender, PropertyGridItemEditorInitializedEventArgs e)
        if (e.Editor is PropertyGridDropDownListEditor)
            var editor = e.Editor as PropertyGridDropDownListEditor;
            var element = editor.EditorElement as BaseDropDownListEditorElement;
            if (!element.IsPopupOpen)

    I hope this helps. Should you have any other questions, do not hesitate to ask.
