.NET Framework Class Library

HtmlTableRowCollection Class

A collection of HtmlTableRow objects that represent the rows of an HtmlTable control. This class cannot be inherited.

System..::.Object
System.Web.UI.HtmlControls..::.HtmlTableRowCollection

Namespace: System.Web.UI.HtmlControls
Assembly: System.Web (in System.Web.dll)

Public NotInheritable Class HtmlTableRowCollection _
	Implements ICollection, IEnumerable

public sealed class HtmlTableRowCollection : ICollection, 
	IEnumerable

public ref class HtmlTableRowCollection sealed : ICollection, 
	IEnumerable

[<Sealed>]
type HtmlTableRowCollection =  
    class
        interface ICollection
        interface IEnumerable
    end

The HtmlTableRowCollection type exposes the following members.

Properties

	Name	Description
	Count	Gets the number of HtmlTableRow objects in the HtmlTableRowCollection collection.
	IsReadOnly	Gets a value indicating whether the HtmlTableRowCollection collection is read-only.
	IsSynchronized	Gets a value indicating whether access to the HtmlTableRowCollection collection is synchronized (thread safe).
	Item	Gets the HtmlTableRow object at the specified index from the HtmlTableRowCollection collection.
	SyncRoot	Gets the object that can be used to synchronize access to the HtmlTableRowCollection collection.

Methods

	Name	Description
	Add	Appends the specified HtmlTableRow object to the end of the HtmlTableRowCollection collection.
	Clear	Removes all HtmlTableRow objects from the HtmlTableRowCollection collection.
	CopyTo	Copies the items from the HtmlTableRowCollection collection to the specified System..::.Array object, starting at the specified index in the array.
	Equals(Object)	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)

	GetType	Gets the Type of the current instance. (Inherited from Object.)
	Insert	Adds an HtmlTableRow object to the specified location in the collection.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	Remove	Removes the specified HtmlTableRow object from the HtmlTableRowCollection collection.
	RemoveAt	Removes the HtmlTableRow object at the specified index from the HtmlTableRowCollection collection.
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Remarks

Use the HtmlTableRowCollection class to programmatically manage a collection of HtmlTableRow objects that represent the rows in an HtmlTable control. This class is commonly used to add, remove, or modify the contents of a row in an HtmlTable control.

Note
An HtmlTable control contains a Rows property that represents a collection of HtmlTableRow objects. Each HtmlTableRow represents an individual row in the table. An HtmlTableRow contains a Cells property that represents a collection of HtmlTableCell objects. These objects, in turn, represent the individual cells of the table. To retrieve an individual cell, first get the HtmlTableRow object, representing the row containing the cell, from the Rows collection of the HtmlTable control. You can then get the HtmlTableCell object, representing the cell in the row, from the Cells collection of the HtmlTableRow.

Note

An HtmlTable control contains a Rows property that represents a collection of HtmlTableRow objects. Each HtmlTableRow represents an individual row in the table. An HtmlTableRow contains a Cells property that represents a collection of HtmlTableCell objects. These objects, in turn, represent the individual cells of the table. To retrieve an individual cell, first get the HtmlTableRow object, representing the row containing the cell, from the Rows collection of the HtmlTable control. You can then get the HtmlTableCell object, representing the cell in the row, from the Cells collection of the HtmlTableRow.

Examples

The following code example demonstrates how to dynamically generate the contents of an HtmlTable control by adding rows to an HtmlTableRowCollection collection. Notice that the Rows property of a table is the HtmlTableRowCollection object.
