How to retrieve the cell value that is available in view only?

You can retrieve the cell value based on the row and column indices in the GridTreeControl, by default.

C#

You can restrict and retrieve the cell value only for rows that are currently available in view by using the GetCellValue helper method.

C#

The GetCellValue helper method helps to decide whether the specified row and column are in the view or not by comparing the given row and column indices with the ScrollRows and ScrollColumns collections. Then the corresponding cell value is returned when the specified row and column indices are currently in the view of the GridTreeControl.

C#
