Occurs when information about row height is requested.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
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 to retrieve the stored height information when the control needs it.

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the MessageBox.Show with Console.WriteLine or appending the message to a multiline TextBox.event. This report helps you to learn when the event occurs and can assist you in debugging. To report on multiple events or on events that occur frequently, consider replacing
To run the example code, paste it into a project that contains an instance of type DataGridView named DataGridView1. Then ensure that the event handler is associated with the event.
