All shapes in a worksheet are contained in the DevExpress.Spreadsheet.ShapeCollection, accessible via the DevExpress.Spreadsheet.Worksheet.Shapes property. Use the SetSelectedShapes method to select multiple shapes in the active worksheet simultaneously. To get the list of shapes selected in the active worksheet, use the GetSelectedShapes method. To specify whether multi-selection is available to end-users in the SpreadsheetControl, use the DevExpress.XtraSpreadsheet.SpreadsheetSelectionOptions.AllowMultiSelection option accessible via the SpreadsheetControl.Options.Behavior.Selection.AllowMultiSelection notation.
To specify a single shape (for example, a picture) selected in the active worksheet, use the SelectedShape or SelectedPicture property.
To select shapes in a specific worksheet of the document loaded in the SpreadsheetControl, use the DevExpress.Spreadsheet.Worksheet.SelectedPicture, DevExpress.Spreadsheet.Worksheet.SelectedShape, DevExpress.Spreadsheet.Worksheet.SetSelectedShapes and DevExpress.Spreadsheet.Worksheet.GetSelectedShapes members of the corresponding worksheet object.
