It turns out, a little confusingly, that you have to set the alpha channel on the backgroundColor rather than the opaque property: mobileControlSet pFieldName, "backgroundColor", "255,255,255,0" mobileControlSet pFieldName, "opaque", false I tried it with the opaque property set to both true and false; it didn't seem to make any difference. In fact, it worked fine without setting the opaque property. The old iOS release notes (and the current dictionary entry for mobileControlSet) give a confusing description of the opaque property of mobile native controls: "Set to false if the control should be rendered with transparency. In particular, set this control to true if you set a backgroundColor that is not fully opaque." Months ago I had printed out the release notes for closer study. Next to that paragraph I penciled in the comment "?". Indeed. Can anyone explain what that means?
