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

public sealed class TableCellCollection : IList, 
	ICollection, IEnumerable

The TableCellCollection type exposes the following members.

  NameDescription
Public propertyCountGets the number of TableCell objects in the TableCellCollection.
Public propertyIsReadOnlyGets a value indicating whether the TableCellCollection is read-only.
Public propertyIsSynchronizedGets a value indicating whether access to the TableCellCollection is synchronized (thread-safe).
Public propertyItemGets a TableCell from the TableCellCollection at the specified index.
Public propertySyncRootGets the object that can be used to synchronize access to the TableCellCollection.

  NameDescription
Public methodAddAppends the specified TableCell to the end of the TableCellCollection.
Public methodAddAtAdds the specified TableCell to the TableCellCollection at the specified index location.
Public methodAddRangeAppends the TableCell objects from the specified array to the end of the collection.
Public methodClearRemoves all TableCell objects from the TableCellCollection.
Public methodCopyToCopies the items from the TableCellCollection to the specified System.Array, starting with the specified index in the System.Array.
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)

Public methodGetCellIndexReturns a value that represents the index of the specified TableCell from the TableCellCollection.
Public methodGetEnumeratorReturns a System.Collections.IEnumerator implemented object that contains all TableCell objects in the TableCellCollection.
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodRemoveRemoves the specified TableCell from the TableCellCollection.

Use this class to programmatically manage a collection of TableCell objects that make up a row in a Table control. This class is commonly used to add or remove cells from a row in a Table control.

NoteNote

A Table control contains a Rows collection that represents a collection of TableRow objects. Each TableRow represents an individual row in the table and contains a Cells collection that represents a collection of TableCell objects. These TableCell objects represent the individual cells in the table. To get an individual cell, you must first get a TableRow from the Rows collection of a Table control. You can then get a TableCell from the Cells collection of the TableRow.

The following example demonstrates how to programmatically fill a Table control. TableCell objects, which represent individual cells, are added to TableRow objects, which represent the individual rows, through the Cells property.
