I tried searching in the demos and samples and didn't see any method to plug-in that would allow saving and opening of ganttview data from an external file, such as an xml.  The only thing I found was by using MSProject importer/exporter but I want to be able to save and open on computers without that software.  Is there something you can point me to or am I on my own to devise something?  Thanks.

Hello Michael,

Indeed, currently the only RadGanttView example showing how to import data from a file is the Import from MS Project example from our demos. 

That said, the example shows how to read an xml file and translate the data to GanttTasks. You can use the approach demonstrated in the article as a baseline with any xml file with some slight changes depending on the structure of the file. 

I hope you find this information helpful. Let me know, if I can be of any further assistance.

Regards,
Vladimir Stoyanov
