I am using XamGrid 10.3 with ColumnLayout. The Default for the Expand is going down, but is it possible to change the direction? We display alot of summary into at the parent level, and detail information at the child level. So, when the user expands, the parent would appear at the bottom.
There isn't any feature built in that would allow you to open the children up. I will forward this post onto our product management team so they can evaluate the idea as a future feature.
