I've got an issue with the way loadlayout works with the RadGridView. My plan is when the user closes the screen the layout will be saved to an xml file. Saving the xml works great. On subsequent loads of the program if a new column has been added to the RadGridView since the layout was last saved when the loadlayout method is called the new column is lost entirely.
Does anyone already have a solution for this? My work around will be to examine the xml first before loading to try and amend it before loading but i'm not sure if i'm missing something obvious?
Thanks!

The described scenario seems to be correct considering the save/load layout functionality that RadGridView offers. Its purpose is to restore the preserved layout in the XML.
Before calling the LoadLayout method, you can iterate the RadGridView.Columns collection and store the columns information into appropriate data structure. After the layout is successfully loaded you can iterate this data structure with the stored columns and add the missing ones. Thus, you will ensure that the columns stored in the XML file will be added to the grid together with the columns coming from the applied DataSource that were missing in the XML file.
I would recommend you to have a look at the following forum thread which is quite useful on this topic: https://www.telerik.com/forums/load-save-layout-customization#3063949
I hope this information helps. If you need any further assistance please don't hesitate to contact me.

Before i call loadlayout i capture a list of objects which contains for each column in the grid the name, headertext and fieldname. This is enough for me once the loadlayout is called to iterate through to check for the existance of the field. If the column isn't there i call grid.columns.add(name,headertext,fieldname).
I will likely add code to check for the removal of a column but i can't see this being as big an issue.
