Changes the selection state of the cell with the specified row and column indexes.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
protected virtual void SetSelectedCellCore( int columnIndex, int rowIndex, bool selected )
columnIndex is less than 0 or greater than the number of columns in the control minus 1.
rowIndex is less than 0 or greater than the number of rows in the control minus 1.
The DataGridView control uses this method whenever it changes the selection state of a cell. The selection state changes without regard to the current SelectionMode property value, and without changing the CurrentCell property value. This is useful when you want to implement your own selection modes.
