I'm using InfragisticsWPF4.v12.1 for saving tile layout into xml file.
The tile layout xml file is saved as the following structure
<?xml version="1.0" encoding="utf-8"?><xamTilesControl assemblyVersion="12.1.20121.2225" layoutVersion="1" isExplicitLayout="true" MinimizedAreaExtentX="1255"> <items /></xamTilesControl>
My question is
When <items> element is set?
The <items> element is likely not being set in this case as you likely have not provided a unique Name or SerializationId to each of the tiles in your XamTilesControl. In order for state information to be saved for a specific tile, at least one of these properties must be set. This, along with other saving and loading layout information is documented here.
Please let me know if you have any other questions or concerns on this matter.
