By default, Selection behavior will be enabled in SfSpreadsheet,but if you want to disable the selection in SfSpreadsheet, then set the AllowSelection Property to be false.

void spreadsheet_WorkbookLoaded(object sender, WorkbookLoadedEventArgs args)
{
    spreadsheet.ActiveGrid.AllowSelection = false;
}

Accessing the Current cell

SfSpreadsheet allows the user to access the active cell by using the CurrentCell property of SelectionController Class.

var cell= spreadsheet.ActiveGrid.SelectionController.CurrentCell;

Accessing the Selected ranges

SfSpreadsheet allows the user to access the selected ranges of the SpreadsheetGrid using SelectedRanges property of SpreadsheetGrid.

var rangeList = spreadsheet.ActiveGrid.SelectedRanges;

NOTE

To get the active range in the selected ranges list, use ActiveRange property of GridRangeInfoList class.

Adding or Clearing the Selection

SfSpreadsheet allows the user to add and clear the selection in the Active SpreadsheetGrid for the given range.

//To Add the Selection for range,
spreadsheet.ActiveGrid.SelectionController.AddSelection(GridRangeInfo.Cells(4,6,5,8));

//To Add the Selection for particular row,
spreadsheet.ActiveGrid.SelectionController.AddSelection(GridRangeInfo.Row(4));

//To Add the Selection for multiple rows,
spreadsheet.ActiveGrid.SelectionController.AddSelection(GridRangeInfo.Rows(4,9));

//To Add the Selection for particular column,
spreadsheet.ActiveGrid.SelectionController.AddSelection(GridRangeInfo.Col(5));

//To Add the Selection for multiple columns,
spreadsheet.ActiveGrid.SelectionController.AddSelection(GridRangeInfo.Cols(5,10));

//To Clear the Selection,
spreadsheet.ActiveGrid.SelectionController.ClearSelection();

Move Current Cell

SfSpreadsheet allows the user to move the current cell to the mentioned cell in SpreadsheetGrid.

//Moves current cell to the mentioned row and column index of cell,
spreadsheet.ActiveGrid.CurrentCell.MoveCurrentCell(5, 5);

//For moving the current cell to a different sheet,
spreadsheet.SetActiveSheet("Sheet2");
spreadsheet.ActiveGrid.CurrentCell.MoveCurrentCell(6, 5);

Converting GridRangeInfo into IRange

SfSpreadsheet allows the user to convert the GridRangeInfo into the equivalent IRange by using ConvertGridRangeToExcelRange method of GridExcelHelper class.

var excelRange = GridExcelHelper.ConvertGridRangeToExcelRange(GridRangeInfo.Cell(4, 5), spreadsheet.ActiveGrid);

TIPS

Users can also convert the IRange into equivalent GridRangeInfo by using ConvertExcelRangeToGridRange method of GridExcelHelper class.
