DataGridViewButtonCell.GetValue Method (Int32)
Retrieves the text associated with the button.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
This method is useful to retrieve the text of a cell in a shared row, which cannot store cell values locally and remain shared. You must pass in the actual row index because shared rows have indexes of -1. For more information about row sharing, see Best Practices for Scaling the Windows Forms DataGridView Control.
