DataFilters / XML Serialization/Deserialization
XML Serialization/Deserialization

The DataFilter control supports serialization through SaveFilterExpression and LoadFilterExpression methods of the C1DataFilter class. The SaveFilterExpression method saves the current filter expressions from C1.Win.DataFilter.C1DataFilter.Filters collection to an XML file. The LoadFilterExpression method loads the saved filter expressions from an XML file.

The following GIF demonstrates serialization and de-serialization support in the DataFilter control.

The application shows serialization and deserialization in the Data filter.

The following code shows an example of saving filter expressions to an XML file:

Private Sub Button_Click(sender As Object, e As RoutedEventArgs)
    'Loads the current filter expressions from an xml file
    c1DataFilter.LoadFilterExpression("SavedFilters.xml")
    MessageBox.Show("Loaded saved Filter state.")
End Sub

The following code shows an example of loading filter expressions from an XML file:

Private Sub Button_Click_1(sender As Object, e As RoutedEventArgs)
    'Saves the current filter expressions to an xml file
    c1DataFilter.SaveFilterExpression("SavedFilters.xml")
    MessageBox.Show("Filter state saved.")
End Sub
