I am trying to allow the user to be able to reload the grid's default/original DisplayLayout after a custom DisplayLayout has been applied. I have a test project that doesn't have much in it except for the save and load functions. When I try to do this using the file system to save the xml instead of a stream, everything works perfectly. When I try to use a Stream, I get an error that says, "Root element is missing." The default/original DisplayLayout will load fine if I don't pass it a custom DisplayLayout to load. The custom DisplayLayout will load fine as well, but when I try to revert back to the default/original, it blows up. In the application I am going to put this into, I can't use the file system as the user will not have rights to write to the file system. This is why I am using a Stream to hold the grid configuration in the meantime. Am I doing this wrong or is there another way to do this?
private Stream _defaultGridConfig = null;
public Stream CurrentGridConfig { get { MemoryStream stream = new MemoryStream(); this.DisplayLayout.SaveAsXml(stream, PropertyCategories.All); return stream; } }
public void Init(Stream UserGridConfiguration) { _defaultGridConfig = CurrentGridConfig; if (UserGridConfiguration != null) this.DisplayLayout.LoadFromXml(UserGridConfiguration, PropertyCategories.All); }
private void ResetGridSettingsEvent(Object sender, EventArgs e) { if (_defaultGridConfig != null) this.DisplayLayout.LoadFromXml(_defaultGridConfig, PropertyCategories.All); }

You should Submit an incident to Infragistics Developer Support.
Thanks for the response. Unfortunately that does not solve my problem. I am already calling the seek to the beginning of the file.

Hi Kyle,
I don't have a solution for you, but I happen to have a similar problem except using VB. I was able to get this working with 7.3 and has been working for some time now (saving and loading using a stream). The problem started happening when I upgraded my Infragistics controls to 8.1. Now I can't load setting I previously saved under the 7.3 version. Have you been able to solve this yet?
