Copies the child controls stored in the ControlCollection object to an System.Array object, beginning at the specified index location in the System.Array.(Inherited from ControlCollection.)

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_pubmethodGetEnumerator()

Retrieves an enumerator that can iterate through the ControlCollection object.(Inherited from ControlCollection.)

System_CAPS_pubmethodGetHashCode()

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

System_CAPS_pubmethodGetType()

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

System_CAPS_pubmethodIndexOf(Control)

Retrieves the index of a specified Control object in the collection.(Inherited from ControlCollection.)

System_CAPS_protmethodMemberwiseClone()

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

System_CAPS_pubmethodRemove(Control)

Removes the specified server control from the parent server control's ControlCollection object.(Inherited from ControlCollection.)

System_CAPS_pubmethodRemoveAt(Int32)

Removes a child control, at the specified index location, from the ControlCollection object.(Inherited from ControlCollection.)

System_CAPS_pubmethodToString()

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

NameDescription
System_CAPS_pubmethodAsParallel()

Overloaded. Enables parallelization of a query.(Defined by ParallelEnumerable.)

System_CAPS_pubmethodAsQueryable()

Overloaded. Converts an IEnumerable to an IQueryable.(Defined by Queryable.)

System_CAPS_pubmethodCast<TResult>()

Casts the elements of an IEnumerable to the specified type.(Defined by Enumerable.)

System_CAPS_pubmethodOfType<TResult>()

Filters the elements of an IEnumerable based on a specified type.(Defined by Enumerable.)

The HtmlTable.HtmlTableRowControlCollection class represents a collection of HtmlTableRow objects for an HtmlTable control. Controls can be added at the end of the collection with the Add method, or at a specified index location in the collection with the AddAt method. Only controls of type HtmlTableRow can be added to the HtmlTable.HtmlTableRowControlCollection collection.

The following code example demonstrates how to create a custom HtmlTable.HtmlTableRowControlCollection that overrides the Add method so that when rows are added to a table, they are always added at the beginning of the table's row collection.
