Selection in JavaScript Spreadsheet control

24 Sep 2021 / 4 minutes to read

Selection provides interactive support to highlight the cell, row, or column that you select. Selection can be done through Mouse, Touch, or Keyboard interaction. To enable selection, set mode as Single | Multiple in selectionSettings. If you set mode to None, it disables the UI selection.

  • The default value for mode in selectionSettings is Multiple.

You have the following options in Selection,

  • Cell selection
  • Row selection
  • Column selection

Cell selection

Cell selection is used to select a single or multiple cells. It can be performed using the selectRange method.

User Interface:

  • Click on a cell to select it (or) use the arrow keys to navigate to it and select it.
  • To select a range, select a cell, then use the left mouse button to select and drag over to other cells (or) use the Shift + arrow keys to select the range.
  • To select non-adjacent cells and cell ranges, hold Ctrl and select the cells.

You can quickly locate and select specific cells or ranges by entering their names or cell references in the Name box, which is located to the left of the formula bar, and also select named or unnamed cells or ranges by using the Go To (Ctrl+G) command.

Row selection

Row selection is used to select a single or multiple rows.

User Interface:

You can perform row selection in any of the following ways,

  • By clicking the row header.
  • To select multiple rows, select a row header with the left mouse button and drag over to other row headers (or) use the Shift + arrow keys to select multiple rows.
  • To select non-adjacent rows, hold Ctrl and select the row header.
  • You can also use the selectRange method for row selection.

The following sample shows the row selection in the spreadsheet, here selecting the 5th row using the selectRange method.
