    Public Properties
     NameDescription
    Public PropertyAutoLoadGets or sets a value indicating whether Load is automatically invoked on startup and when a change occurs that impacts the query composed by the ClientViewSource. The default is True.  
    Public PropertyBaseViewGets or sets an instance of C1.Data.ClientView<T> that the ClientViewSource uses as the base for composing queries.  
    Public PropertyCacheTimeoutGets or sets the period of time entities loaded in virtual mode are kept in the cache without checking whether they are needed or not. If an entity was neither used nor considered needed for a period of time longer than CacheTimeout, ClientViewSource may evict it from the cache.  
    Public PropertyCurrentClientViewGets the current client view used to load entities, or null in virtual mode.  
    Public PropertyDataViewGets the current view of entities resulting from the last load operation.  
    Public PropertyDependencyObjectType (Inherited from System.Windows.DependencyObject)
    Public PropertyDispatcher (Inherited from System.Windows.Threading.DispatcherObject)
    Public PropertyFilterDescriptorsGets the collection of FilterDescriptor objects used when performing loads.  
    Public PropertyFilterOperatorGets or sets the logical operator used for combinining FilterDescriptors in the filter collection. The default value is FilterDescriptorLogicalOperator.And.  
    Public PropertyGroupDescriptorsGets the collection of GroupDescriptor objects used to organize the loaded entities into groups.  
    Public PropertyIncludeGets or sets a comma-separated list of property paths that specify related objects to include during the Load operation.  
    Public PropertyIsLoadingDataGets a value indicating whether the ClientViewSource is currently loading data.  
    Public PropertyIsSealed (Inherited from System.Windows.DependencyObject)
    Public PropertyLoadCommandGets an System.Windows.Input.ICommand that invokes Load on this ClientViewSource.  
    Public PropertyLoadDelayGets or sets the delay before an automatic data loading operation is started. It is the delay from the time a change prompting automatic load occurs until the time the resulting Load is started. The default delay is 25 milliseconds.  
    Public PropertyLoadSizeGets or sets the maximum number of items to load each time a Load is executed. When equal to 0, all requested entities will be loaded. The default is 0.  
    Public PropertyMoveToFirstOnLoadGets or sets a value indicating that the first item must be made current after Load operation is completed if current item was not set by other means.  
    Public PropertyNameGets a name of this ClientViewSource to reference it in a C1DataSource.ViewSources collection. By default it is determined by the EntitySetName (for Entity Framework) or QueryName (for RIA Services), but it can be overrided by NameOverride.  
    Public PropertyNameOverrideGets or sets a value that overrides the value of the Name property.  
    Public PropertyPageSizeGets or sets the number of items displayed on each page of the DataView, or the number of items to fetch in each query in virtual mode, or 0 to disable paging.  
    Public PropertySortDescriptorsGets the collection of SortDescriptor objects used to sort the data.  
    Public PropertyVirtualModeGets or sets a value indicating whether the ClientViewSource is in virtual mode. Virtual mode is an innovative technology allowing to bind GUI controls directly to very large data sets without delays and performance degradation and without inconvenience of paging. By default, virtual mode is disabled (the default value is VirtualModeKind.None).

    Public Methods
     NameDescription
    Public MethodClearValueOverloaded.  (Inherited from System.Windows.DependencyObject)
    Public MethodCoerceValue (Inherited from System.Windows.DependencyObject)
    Public MethodDeferLoadUsed to group changes to multiple load-affecting properties together, deferring the resulting load operations so a single load operation is performed in the end, that is, when the object returned from this method is disposed.  
    Public MethodEquals (Inherited from System.Windows.DependencyObject)
    Public MethodGetHashCode (Inherited from System.Windows.DependencyObject)
    Public MethodGetLocalValueEnumerator (Inherited from System.Windows.DependencyObject)
    Public MethodGetValue (Inherited from System.Windows.DependencyObject)
    Public MethodInvalidateProperty (Inherited from System.Windows.DependencyObject)
    Public MethodLoadStarts a load operation. Any pending load will be implicitly canceled.  
    Public MethodLoadRangeIf in virtual mode, loads a specific range of entities.  
    Public MethodReadLocalValue (Inherited from System.Windows.DependencyObject)
    Public MethodRefreshStarts a load operation ignoring the client-side cache. Any pending load will be implicitly canceled.  
    Public MethodSetCurrentValue (Inherited from System.Windows.DependencyObject)
    Public MethodSetValueOverloaded.  (Inherited from System.Windows.DependencyObject)

    Public Events
     NameDescription
