Saving only the root control with Persistence framework ?

[Yvan]

Hi,

It is possible to persist with only the root object with the Persistence Framework ?
I have a RadExpander with many controls into it. I only want to persist the RadExpander control properties (like IsExpanded, IsEnabled), not is children controls.

For example, I want to persist IsExpanded property, not the two textboxes controls:

<telerik:RadExpander x:Name="expander" Header="My Header" IsExpanded="True" >
   <StackPanel Orientation="Vertical">
       <TextBox Text="{Binding ExampleBinding1}" />
       <TextBox Text="{Binding ExampleBinding1}" />
   </StackPanel>
</telerik:RadExpander>

It is possible ?



Thanks

Hi Yvan,

You can define the PersistenceManager.SerializationOptions to control which properties of the RadExpander to be persisted. This article can give you more information about this property and how you can use it.

Basically in your case you can exclude the Content property from the RadExpander properties that will be persisted:

<telerik:RadExpander x:Name="expander" Header="My Header" IsExpanded="True" >
    <telerik:PersistenceManager.SerializationOptions>
      <telerik:SerializationMetadataCollection>
      <telerik:PropertyNameMetadata Condition="Except" Expression="Content" SearchType="PropertyName" />
    </telerik:SerializationMetadataCollection>
    <StackPanel Orientation="Vertical">
      <TextBox Text="{Binding ExampleBinding1}" />
      <TextBox Text="{Binding ExampleBinding1}" />
    </StackPanel>
</telerik:RadExpander>

Give this a try and let me know if it helps or if we can further assist you.
