| Wijmo Control Toolkit Extender Controls > C1Gallery Extender > C1GalleryExtender Tutorial > Step 3 of 4: Customizing the Gallery |
In this topic you will set some of the properties for the C1GalleryExtender to change the appearance of the thumbnails.
The markup for the GalleryExtender will now look like this:
<wijmo:C1GalleryExtender ID="Panel1_C1GalleryExtender" runat="server"
TargetControlID="Panel1" ThumbnailDirection="After"
ThumbnailOrientation="Vertical" ThumbsDisplay="2">
</wijmo:C1GalleryExtender>
Now run the project to see the gallery of images.
