public class OfTypeExpression : DataSourceExpression

NameDescription
System_CAPS_pubmethodOfTypeExpression()

Initializes a new instance of the OfTypeExpression class.

System_CAPS_pubmethodOfTypeExpression(Type)

Initializes a new instance of the OfTypeExpression class using a specified type.

NameDescription
System_CAPS_protpropertyContext

Gets the HttpContext instance of the owner control.(Inherited from DataSourceExpression.)

System_CAPS_pubpropertyDataSource

Gets the data source object that is associated with the owner control.(Inherited from DataSourceExpression.)

System_CAPS_protpropertyIsTrackingViewState

Gets a value that indicates whether a data source expression object is tracking its view state changes.(Inherited from DataSourceExpression.)

System_CAPS_protpropertyOwner

Gets the owner control.(Inherited from DataSourceExpression.)

System_CAPS_pubpropertyTypeName

Gets or sets the type that the filter is based on.

System_CAPS_protpropertyViewState

Gets an instance of the StateBag class that contains the current view state information.(Inherited from DataSourceExpression.)

NameDescription
System_CAPS_pubmethodEquals(Object)

Determines whether the specified object is equal to the current object.(Inherited from Object.)

System_CAPS_protmethodFinalize()

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)

System_CAPS_pubmethodGetHashCode()

Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethodGetQueryable(IQueryable)

Returns the query that the OfTypeExpression was performed on. (Overrides DataSourceExpression.GetQueryable(IQueryable).)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_protmethodLoadViewState(Object)

Loads the state of the values in the DataSourceExpression object that must be persisted.(Inherited from DataSourceExpression.)

System_CAPS_protmethodMemberwiseClone()

Creates a shallow copy of the current Object.(Inherited from Object.)

System_CAPS_protmethodSaveViewState()

Saves the current view state of the DataSourceExpression object.(Inherited from DataSourceExpression.)

System_CAPS_pubmethodSetContext(Control, HttpContext, IQueryableDataSource)

Sets the HTTP context of the DataSourceExpression object that uses the specified owner control, HttpContext instance, and IQueryableDataSource object.(Inherited from DataSourceExpression.)

System_CAPS_pubmethodSetDirty()

Marks the DataSourceExpression object so that its state will be saved in view state.(Inherited from DataSourceExpression.)

System_CAPS_pubmethodToString()

Returns a string that represents the current object.(Inherited from Object.)

System_CAPS_protmethodTrackViewState()

Tracks view state changes of the DataSourceExpression object so that the changes can be stored in the StateBag object for the data source expression object.(Inherited from DataSourceExpression.)

NameDescription
System_CAPS_pubinterfaceSystem_CAPS_privmethodIStateManager.LoadViewState(Object)

When implemented by a class, loads the previously saved view state of the data source expression object.(Inherited from DataSourceExpression.)

System_CAPS_pubinterfaceSystem_CAPS_privmethodIStateManager.SaveViewState()

When implemented by a class, saves the current view state of the DataSourceExpression object.(Inherited from DataSourceExpression.)

System_CAPS_pubinterfaceSystem_CAPS_privmethodIStateManager.TrackViewState()

When implemented by a class, tracks view state changes of the DataSourceExpression object so that the changes can be stored in the StateBag object for the data source expression object.(Inherited from DataSourceExpression.)

System_CAPS_pubinterfaceSystem_CAPS_privpropertyIStateManager.IsTrackingViewState

When implemented by a class, gets a value that indicates whether a data source expression object is tracking its view state changes.(Inherited from DataSourceExpression.)

This expression filters out elements in the data source that are not of the specified type.
