I'm too interested in this subject, and the documentation does not explain very well how to do this and many other... "not there are clear examples"
for example in the documentation says that you can put pictures in the ComboBoxControl. but, I did. and apparently, I did something wrong because the picture does not appear.
xml code:
<Control xsi:type="ComboBoxControl" Id="xxxx">
<Position Top="10" Height="32" Width="60" Left="10" />
<Items>
<Item Id="1">1</Item>
<Item Id="2">2</Item>
<Item Id="3">3</Item>
</Items>
<Images>
<Image Id="1"><Name>imagen1</Name></Image>
<Image Id="2"><Name>imagen2</Name></Image>
<Image Id="3"><Name>imagen3</Name></Image>
</Images>
</Control>
and I noted that the images have the same size and format are of .png
Clearly what I want to do is to incorporate images in the panel of options and not customize ComboBoxControl...
edit: I presume the ComboBoxControl, not has CustomLook options, as other Controls.
