Remarks

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.

Note

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.

Properties

Count Count Count Count

Gets the number of TableCell objects in the TableCellCollection.

IsReadOnly IsReadOnly IsReadOnly IsReadOnly

Gets a value indicating whether the TableCellCollection is read-only.

IsSynchronized IsSynchronized IsSynchronized IsSynchronized

Gets a value indicating whether access to the TableCellCollection is synchronized (thread-safe).

Item[Int32] Item[Int32] Item[Int32] Item[Int32]

Gets a TableCell from the TableCellCollection at the specified index.

SyncRoot SyncRoot SyncRoot SyncRoot

Gets the object that can be used to synchronize access to the TableCellCollection.
