Remarks

The TableItemStyle class represents the style properties for an element of a control that renders as a TableRow or TableCell. You can control the vertical and horizontal alignment of the contents in an item of the table by setting the HorizontalAlign and VerticalAlign properties, respectively. You can also specify whether the contents of the cell automatically continue on the next line when the end of the cell is reached by setting the Wrap property.

This class provides methods that are useful for creating a style for an item in the Table control. You can use the CopyFrom and MergeWith methods to copy or merge the style properties of another TableItemStyle with the instance of the TableItemStyle that the method is called from.

Constructors

TableItemStyle()	Creates a new instance of the TableItemStyle class using default values.
TableItemStyle(StateBag)	Creates a new instance of the TableItemStyle class with the specified state bag.

LoadViewState(Object)	Loads the previously saved state. (Inherited from Style)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
MemberwiseClone(Boolean)	Creates a shallow copy of the current MarshalByRefObject object. (Inherited from MarshalByRefObject)
MergeWith(Style)	Combines the style properties of the specified Style into the instance of the TableItemStyle class that this method is called from.
Reset()	Removes any defined style elements from the style.
SaveViewState()	A protected method. Saves any state that has been modified after the TrackViewState() method was invoked. (Inherited from Style)
SetBit(Int32)	A protected internal method. Sets an internal bitmask field that indicates the style properties that are stored in the state bag. (Inherited from Style)
SetDirty()	Marks the Style so that its state will be recorded in view state. (Inherited from Style)
ToString()	Returns a string that represents the current object. (Inherited from Style)
TrackViewState()	A protected method. Marks the beginning for tracking state changes on the control. Any changes made after tracking has begun will be tracked and saved as part of the control view state. (Inherited from Style)

Disposed

Occurs when the component is disposed by a call to the Dispose() method.

(Inherited from Component)
