PropertyGridDropDownListEditor auto-open List?

[Andrea]

Hello,

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?

Thanks!

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,
