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

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.
@Html.EJS().Spreadsheet("spreadsheet").Created("createHandler").SelectionSettings(selectionSettings =>
{
selectionSettings.Mode(SelectionMode.Multiple);
}).Sheets(sheet =>
{
sheet.Ranges(ranges =>
{
ranges.DataSource((IEnumerable<object>)ViewBag.DefaultData).Add();
}).Columns(column =>
{
column.Width(130).Add();
column.Width(92).Add();
column.Width(96).Add();
}).Add();
}).Render()
<script>
function createHandler() {
//Applies format to specified range
this.cellFormat({ fontWeight: 'bold' }, 'A1:D1');
var colCount = this.getActiveSheet().colCount;
this.selectRange(ej.spreadsheet.getRangeAddress([4, 0, 4, colCount]));
}
</script>
public IActionResult Index()
{
List<object> data = new List<object>()
{
new { Expense Type= "Housing", Projected Cost= "7000", Actual Cost= "7500", Difference= "-500" },
new { Expense Type= "Transportation", Projected Cost= "500", Actual Cost= "500", Difference= "0" },
new { Expense Type= "Insurance", Projected Cost= "1000", Actual Cost= "1000", Difference= "0" },
new { Expense Type= "Food", Projected Cost= "2000", Actual Cost= "1800", Difference= "200" },
new { Expense Type= "Pets", Projected Cost= "300", Actual Cost= "200", Difference= "100" },

@Html.EJS().Spreadsheet("spreadsheet").Created("createHandler").SelectionSettings(selectionSettings =>
{
selectionSettings.Mode(SelectionMode.Multiple);
}).Sheets(sheet =>
{
sheet.Ranges(ranges =>
{
ranges.DataSource((IEnumerable<object>)ViewBag.DefaultData).Add();
}).Columns(column =>
{
column.Width(130).Add();
column.Width(92).Add();
column.Width(96).Add();
}).Add();
}).Render()
<script>
function createHandler() {
//Applies format to specified range
this.cellFormat({ fontWeight: 'bold' }, 'A1:D1');
var rowCount = this.getActiveSheet().rowCount;
this.selectRange(ej.spreadsheet.getRangeAddress([0, 2, rowCount, 2]));
}
</script>
public IActionResult Index()
{
List<object> data = new List<object>()
{
new { Expense Type= "Housing", Projected Cost= "7000", Actual Cost= "7500", Difference= "-500" },
new { Expense Type= "Transportation", Projected Cost= "500", Actual Cost= "500", Difference= "0" },
