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)
{
element.ShowPopup();
}
}
}
I hope this helps. Should you have any other questions, do not hesitate to ask.
Regards,
Dimitar
