SpreadsheetControl.SetSelectedRanges(IList<CellRange>) Method

Selects multiple ranges in the active worksheet.

Namespace: DevExpress.Xpf.Spreadsheet

Assembly: DevExpress.Xpf.Spreadsheet.v23.2.dll

NuGet Package: DevExpress.Wpf.Spreadsheet

Declaration

C#

public bool SetSelectedRanges(
    IList<CellRange> ranges
)

VB.NET

Public Function SetSelectedRanges(
    ranges As IList(Of CellRange)
) As Boolean

Parameters

Name	Type	Description
ranges	IList<CellRange>	A list of the CellRange objects.

Returns

Type	Description
Boolean	true if cell ranges are selected successfully; otherwise false. If you pass null (Nothing in Visual Basic), or an empty list, or a list that contains at least one cell range located in a worksheet other than the active worksheet, the method returns false.

Remarks

The image below illustrates the use of the SpreadsheetControl.SetSelectedRanges method to select multiple non-adjacent ranges. The SpreadsheetControl.SelectedCell sets the selected (active) cell that gets user input. Note that if a cell outside the selected ranges was assigned to the SelectedCell property, selected ranges would be reset so that the active cell becomes the only selected range in the worksheet.

CellActions.cs

static void SetSelectedRanges(SpreadsheetControl control)
{
    control.BeginUpdate();
    Worksheet worksheet = control.ActiveWorksheet;

    CellRange r1 = worksheet.Range["A1:B10"];
    CellRange r2 = worksheet.Range["E12"];
    CellRange r3 = worksheet.Range["D4:E7"];
    List<CellRange> rlist = new List<CellRange>() { r1, r2, r3 };
    control.SetSelectedRanges(rlist);

    control.SelectedCell = worksheet.Cells["E5"];

    control.EndUpdate();
}

CellActions.vb

Private Shared Sub SetSelectedRanges(ByVal control As SpreadsheetControl)
    control.BeginUpdate()
    Try
        Dim worksheet As Worksheet = control.Document.Worksheets.ActiveWorksheet
        Dim r1 As CellRange = worksheet.Range("A1:B10")
        Dim r2 As CellRange = worksheet.Range("E12")
        Dim r3 As CellRange = worksheet.Range("D4:E7")
        Dim rlist As New List(Of CellRange)() From {r1, r2, r3}
        control.SetSelectedRanges(rlist)

        control.SelectedCell = worksheet.Cells("E5")
    Finally
        control.EndUpdate()
    End Try
End Sub

End-users can select multiple ranges if the SpreadsheetSelectionOptions.AllowMultiSelection option is true. This option is accessible via the SpreadsheetControl.Options.Behavior.AllowMultiSelection notation.

Note

To select ranges in a specific worksheet (which may or may not be active) of the document loaded in the SpreadsheetControl, use the Worksheet.SetSelectedRanges method of the worksheet object.
