Hi Martin,

I agree that there are related. Both behaviors will be taken into account when the team starts working on this behavior. I have already related both items.

Hello Martin,

Thank you for the provided steps.

The reported behavior is related to the one which is already logged in our Feedback Portal. You can subscribe to the item so that you could get notified of its status change. In the meantime what I can suggest as a workaround is similar to the one shared in the feedback item. You can subscribe to the EditorInitialized event of the RadPropertyGrid. In the event handler, you can check the editor type and change the Text property of the editor if the incoming value is null.

private void RadPropertyGrid1_EditorInitialized(object sender, PropertyGridItemEditorInitializedEventArgs e)
{
    if (e.Editor is PropertyGridSpinEditor spinEdit)
    {
        if (spinEdit.EditorElement is BaseSpinEditorElement editorElement && editorElement.EnableNullValueInput)
        {
            if(string.IsNullOrWhiteSpace(e.ItemElement.Text))
            {
                editorElement.Text = null;
            }
        }
    }
}
