Hello,

I have been looking into Matt's sample and I modified it so now the sorting is applied after loading the settings. Basically when the column is removed and then added the sorting is reset, this is why I save the sort direction in a temp variable and set it after the remove/add operations.

@Matt:

Thank you for taking the time to reply to John's posting.

Unfortunately, if you try to use the approach outlined in the sample code AND save the column's sort direction (e.g. ascending/descending)... the sort settings are lost when you re-order the columns.

Are you able to observe the same results? Do you have any recommendations on how to mitigate this problem?

STEPS TO REPRODUCE

1. Download Matt's sample code
2. Add the following persistence setting to MainPage.xaml:
   <ig:PropertyNamePersistenceInfo PropertyName="SortingSettings"/>
3. Start the application.
4. Sort a column: descending
5. Go through the process of persisting/saving the XamGrid control
6. Go through the process of deserializing/loading the XamGrid control
7. If the column re-ordering code is allowed to execute: then column sorting won't restore propertly
   If the column re-ordering code is commended out: then the column sorting will work as expected

COLUMN REORDERING CODE (from: MainPage.Xaml.cs)

 foreach (Column c in xgrid1.Columns)

{
    int i = int.Parse(c.Tag.ToString());
    xgrid1.Columns.Remove(c);
    xgrid1.Columns.Insert(i, c);
 
}

HI,

 Please let me know if you need further assistance regarding this case.

HI,

 You do not have to save the whole column collection.

 Here  sample that saves the column order and width.

I only want to save certain things about columns (width, ordering, sorting, grouping, filtering).  right now my persistance settings look like this

PersistenceSettings set = new PersistenceSettings();
set.LoadPersistenceOptions = Infragistics.Persistence.Primitives.PersistenceOption.OnlySpecified;
set.SavePersistenceOptions = Infragistics.Persistence.Primitives.PersistenceOption.OnlySpecified;
PropertyNamePersistenceInfo nInfo = new PropertyNamePersistenceInfo();
nInfo.PropertyName = "Columns";
nInfo.Options = Infragistics.Persistence.Primitives.PropertyNamePersistenceOptions.PropertyName;
set.PropertySettings.Add(nInfo);
nInfo = new PropertyNamePersistenceInfo();
nInfo.PropertyName = "FilteringSettings";
nInfo.Options = Infragistics.Persistence.Primitives.PropertyNamePersistenceOptions.PropertyName;
set.PropertySettings.Add(nInfo);
nInfo = new PropertyNamePersistenceInfo();
nInfo.PropertyName = "SortedColumns";
nInfo.Options = Infragistics.Persistence.Primitives.PropertyNamePersistenceOptions.Contains;
set.PropertySettings.Add(nInfo);
nInfo = new PropertyNamePersistenceInfo();
nInfo.PropertyName = "GroupByColumns";
nInfo.Options = Infragistics.Persistence.Primitives.PropertyNamePersistenceOptions.Contains;
set.PropertySettings.Add(nInfo);
nInfo = new PropertyNamePersistenceInfo();
nInfo.PropertyName = "SummaryRowSettings";
nInfo.Options = Infragistics.Persistence.Primitives.PropertyNamePersistenceOptions.PropertyName;
set.PropertySettings.Add(nInfo);

But this saves a lot more information than I need.  Is there a simple way to do what I want?
