Gets a DataGridLength structure that represents the cell-based automatic sizing mode.
Assembly: PresentationFramework (in PresentationFramework.dll)
The cell-based automatic sizing mode sizes DataGrid columns based on the contents of cells in the column, not including column headers. This sizing mode will cause columns to expand if content that is larger than the current column size is scrolled into view. The column will not shrink after the content is scrolled out of view.
