I'd like to customise the property grid so that there is a button in one row that the user can click to perform an action. By giving the relevant property an Editor attribute and having a class inherit from UITypeEditor I can get a button with an ellipsis to appear on the right of the property grid row. But I don't want an ellipsis there. I would like to put my own picture there, or if the button could just be blank that would be OK. Can anyone help?
