Inherits StateManagedCollection- Inheritance
Remarks
Use the StyleCollection class to store and manage Style objects for a control. Control developers can use this class to contain a set of styles that apply to different portions of the control.
The collection dynamically increases in size as objects are added. Indexes in this collection are zero-based. Use the Count property to determine how many objects are in the collection.
Additionally, use the StyleCollection methods and properties to provide the following functionality:
The Add method to add a single style to the collection.
The Insert method to add a style at a particular index within the collection.
The Remove method to remove a style from the collection.
The RemoveAt method to remove the style located at a particular index.
The Contains method to determine whether a particular style is already in the collection.
The IndexOf method to retrieve the index of a style within the collection.
The Clear method to remove all the styles from the collection.
Properties
| Count |
Gets the number of elements contained in the StateManagedCollection collection. (Inherited from StateManagedCollection) |
| Item[Int32] |
Gets the Style object at the specified index location in the StyleCollection object. |
Methods
| Add(Style) |
Appends a specified Style object to the end of the StyleCollection object. |
| Clear() |
Removes all items from the StateManagedCollection collection. (Inherited from StateManagedCollection) |
| Contains(Style) |
Determines whether the specified style is contained within the collection. |
| CopyTo(Array, Int32) |
Copies the elements of the StateManagedCollection collection to an array, starting at a particular array index. (Inherited from StateManagedCollection) |
| CopyTo(Style[], Int32) |
Copies the elements of the StyleCollection to a one-dimensional Style array, starting at the specified index of the target array. |
| CreateKnownType(Int32) |
Creates an instance of the Style class, based on the single element collection returned by the GetKnownTypes() method. |
| Equals(Object) |
Determines whether the specified object is equal to the current object. (Inherited from Object) |
| GetEnumerator() |
Returns an iterator that iterates through the StateManagedCollection collection. (Inherited from StateManagedCollection) |
| GetHashCode() |
Serves as the default hash function. (Inherited from Object) |
| GetKnownTypes() |
Gets an array of the IStateManager types that the StyleCollection can contain. |
| GetType() |
Gets the Type of the current instance. (Inherited from Object) |
| IndexOf(Style) |
Returns the index of the specified Style object within the collection. |
| Insert(Int32, Style) |
Inserts a specified Style object into the StyleCollection at the specified index location. |
| MemberwiseClone() |
Creates a shallow copy of the current Object. (Inherited from Object) |
| OnClear() |
When overridden in a derived class, performs additional work before the Clear() method removes all items from the collection. (Inherited from StateManagedCollection) |
| OnClearComplete() |
When overridden in a derived class, performs additional work after the Clear() method finishes removing all items from the collection. (Inherited from StateManagedCollection) |
| OnInsert(Int32, Object) |
When overridden in a derived class, performs additional work before the IList.Insert(Int32, Object) or IList.Add(Object) method adds an item to the collection. (Inherited from StateManagedCollection) |
| OnInsertComplete(Int32, Object) |
When overridden in a derived class, performs additional work after the IList.Insert(Int32, Object) or IList.Add(Object) method adds an item to the collection. (Inherited from StateManagedCollection) |
| OnRemove(Int32, Object) |
When overridden in a derived class, performs additional work before the IList.Remove(Object) or IList.RemoveAt(Int32) method removes the specified item from the collection. (Inherited from StateManagedCollection) |
| OnRemoveComplete(Int32, Object) |
When overridden in a derived class, performs additional work after the IList.Remove(Object) or IList.RemoveAt(Int32) method removes the specified item from the collection. (Inherited from StateManagedCollection) |
| OnValidate(Object) |
When overridden in a derived class, validates an element of the StateManagedCollection collection. (Inherited from StateManagedCollection) |
| Remove(Style) |
Removes the specified Style object from the StyleCollection object. |
| RemoveAt(Int32) |
Removes the Style object at the specified index location from the StyleCollection object. |
| SetDirty() |
Forces the entire StateManagedCollection collection to be serialized into view state. (Inherited from StateManagedCollection) |
| SetDirtyObject(Object) |
Instructs the input Style object contained in the collection to record its entire state to view state, rather than recording only change information. |
| ToString() |
Returns a string that represents the current object. (Inherited from Object) |
Explicit Interface Implementations
