One of our clients just started using the IG Column Options control for grid. They suddenly requested they wish to save the layout once they have applied all the columns. We use a XML file to add the columns to the grid and all the settings for for the column type are in the xml including the order. I have already written the code to look at the band's columns and pickout the columns that are visible and their order. I wanted to find out what will be the best way to work this where I can change the order after my xml rendering has taken place or is there any way to serialize/deserialize the structure/layout for the grid?
