DataGridView.RowHeightInfoNeeded Event

Note: This event is new in the .NET Framework version 2.0.

Occurs when information about row height is requested.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in

public event DataGridViewRowHeightInfoNeededEventHandler RowHeightInfoNeeded
/** @event */
public void add_RowHeightInfoNeeded (DataGridViewRowHeightInfoNeededEventHandler value)

/** @event */
public void remove_RowHeightInfoNeeded (DataGridViewRowHeightInfoNeededEventHandler value)

JScript supports the use of events, but not the declaration of new ones.

This event is useful for preserving custom row heights after a sorting operation. This is necessary because sorting operations are normally handled by the data source, which does not keep track of the correspondence between rows of data and rows in the control. This event occurs only when the DataSource property has been set or when the VirtualMode property is true. In the latter case, you provide your own data store and sorting operations. Handle the RowHeightInfoPushed event to store updated height information when the user changes a row height. Use RowHeightInfoNeeded to retrieve the stored height information when the control needs it.

For more information about handling events, see Consuming Events.
