Specify Persisted Properties (XamGrid)
posted

We encounter massive performance issues while persisting and restoring the XamGrid with large data. We want to specifiy the persisted properties, because on the one hand the stored byte-array is too large and on the other hand it might improve the performance of the restoring-process. At the moment this are our PersistenceSettings:

_settings = new PersistenceSettings
{
SavePersistenceOptions = PersistenceOption.OnlySpecified,
LoadPersistenceOptions = PersistenceOption.OnlySpecified
};
_settings.PropertySettings.Add(new PropertyNamePersistenceInfo
{
PropertyName = "Columns",
Options = PropertyNamePersistenceOptions.PropertyName
});
_settings.PropertySettings.Add(new PropertyNamePersistenceInfo
{
PropertyName = "GroupByColumns",
Options = PropertyNamePersistenceOptions.PropertyName
});
_settings.PropertySettings.Add(new PropertyNamePersistenceInfo
{
PropertyName = "SortedColumns",
Options = PropertyNamePersistenceOptions.PropertyName
});

In general we want to store the FilterRow, GroupedBy, ColumnPosition, ColumnWidth, HiddenColumns, SortedColumns.  My question is for example: Do I really have to store the whole property "GroupByColumns" to know which columns where grouped? Same for the other properties.

I've attached a solution where you can reproduce the issue. Just play arround with Save and Load....

    Hi,

     

    Thank you for your post. I have been looking into your sample application and I can see a delay only when restoring a column sorting. Could you please tell me if this is your scenario because I need to have specific steps for reproducing an issue?

     

    Looking forward to hearing from you.
