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

public void UpdateRowHeightInfo(
	int rowIndex,
	bool updateToEnd


Type: System.Int32

Type: System.Boolean

true to update the specified row and all subsequent rows.


rowIndex is less than 0 and updateToEnd is true.


rowIndex is less than -1 and updateToEnd is false.


rowIndex is greater than the highest row index in the Rows collection.

This method is useful when you maintain row heights yourself using handlers for the RowHeightInfoNeeded and RowHeightInfoPushed events. Call this method whenever you change the stored row heights outside of a RowHeightInfoPushed event handler. This will force the DataGridView control to retrieve the updated height information through the RowHeightInfoNeeded event handler.
