XLSX: Work with drawing objects (pictures, charts, shapes) on XLSX page

In This Topic

SpreadsheetEditorControl and WpfSpreadsheetEditorControl controls allow to work (view, add, set, delete) with drawing objects of XLSX worksheet in desktop (WinForms, WPF) application.
The "drawing object" is a picture, chart or shape. The drawing objects can be changed visually using mouse/keyboard or programmatically.

Add new picture to the XLSX worksheet

Here is C#/VB.NET code that demonstrates how to add a new picture to the focused XLSX worksheet:

public void AddPictureToXlsxWorksheet(
    Vintasoft.Imaging.Office.Spreadsheet.UI.SpreadsheetEditorControl editorControl,
    System.IO.Stream imageStream)
{
    // get visual editor for spreadsheet document
    Vintasoft.Imaging.Office.Spreadsheet.UI.SpreadsheetVisualEditor spreadsheetVisualEditor = editorControl.VisualEditor;

    // create image data
    Vintasoft.Imaging.ImageData imagedata = new Vintasoft.Imaging.ImageData(imageStream);

    // add image to the focused worksheet
    spreadsheetVisualEditor.AddPicture(imagedata);
}

VB.NET

Public Sub AddPictureToXlsxWorksheet(editorControl As Vintasoft.Imaging.Office.Spreadsheet.UI.SpreadsheetEditorControl, imageStream As System.IO.Stream)
    ' get visual editor for spreadsheet document
    Dim spreadsheetVisualEditor As Vintasoft.Imaging.Office.Spreadsheet.UI.SpreadsheetVisualEditor = editorControl.VisualEditor

    ' create image data
    Dim imagedata As New Vintasoft.Imaging.ImageData(imageStream)

    ' add image to the focused worksheet
    spreadsheetVisualEditor.AddPicture(imagedata)
End Sub

Set a bitmap for existing picture on the XLSX worksheet

Here is C#/VB.NET code that demonstrates how to set a bitmap for existing picture on the XLSX worksheet:

public void SetPictureOnFocusedXlsxWorksheet(
    Vintasoft.Imaging.Office.Spreadsheet.UI.SpreadsheetEditorControl editorControl,
    System.IO.Stream imageStream)
{
    // get visual editor for spreadsheet document
    Vintasoft.Imaging.Office.Spreadsheet.UI.SpreadsheetVisualEditor spreadsheetVisualEditor = editorControl.VisualEditor;

    // if focused worksheet does not have focused drawing
    if (spreadsheetVisualEditor.FocusedDrawing == null)
        throw new System.Exception("Worksheet does not have focused drawing.");

    // create image data
    Vintasoft.Imaging.ImageData imagedata = new Vintasoft.Imaging.ImageData(imageStream);

    // set image for focused drawing
    spreadsheetVisualEditor.SetDrawingPicture(imagedata);
}

VB.NET

Public Sub SetPictureOnFocusedXlsxWorksheet(editorControl As Vintasoft.Imaging.Office.Spreadsheet.UI.SpreadsheetEditorControl, imageStream As System.IO.Stream)
    ' get visual editor for spreadsheet document
    Dim spreadsheetVisualEditor As Vintasoft.Imaging.Office.Spreadsheet.UI.SpreadsheetVisualEditor = editorControl.VisualEditor

    ' if focused worksheet does not have focused drawing
    If spreadsheetVisualEditor.FocusedDrawing Is Nothing Then
        Throw New System.Exception("Worksheet does not have focused drawing.")
    End If

    ' create image data
    Dim imagedata As New Vintasoft.Imaging.ImageData(imageStream)

    ' set image for focused drawing
    spreadsheetVisualEditor.SetDrawingPicture(imagedata)
End Sub

Delete the picture from XLSX worksheet

Here is C#/VB.NET code that demonstrates how to delete the picture from XLSX worksheet:

public void DeletePictureFromXlsxWorksheet(Vintasoft.Imaging.Office.Spreadsheet.UI.SpreadsheetEditorControl editorControl)
{
    // get visual editor for spreadsheet document
    Vintasoft.Imaging.Office.Spreadsheet.UI.SpreadsheetVisualEditor spreadsheetVisualEditor = editorControl.VisualEditor;

    // if focused worksheet does not have focused drawing
    if (spreadsheetVisualEditor.FocusedDrawing == null)
        throw new System.Exception("Worksheet does not have focused drawing.");

    // delete the focused picture from the focused worksheet
    spreadsheetVisualEditor.RemoveFocusedDrawing();
}

VB.NET

Public Sub DeletePictureFromXlsxWorksheet(editorControl As Vintasoft.Imaging.Office.Spreadsheet.UI.SpreadsheetEditorControl)
    ' get visual editor for spreadsheet document
    Dim spreadsheetVisualEditor As Vintasoft.Imaging.Office.Spreadsheet.UI.SpreadsheetVisualEditor = editorControl.VisualEditor

    ' if focused worksheet does not have focused drawing
    If spreadsheetVisualEditor.FocusedDrawing Is Nothing Then
        Throw New System.Exception("Worksheet does not have focused drawing.")
    End If

    ' delete the focused picture from the focused worksheet
    spreadsheetVisualEditor.RemoveFocusedDrawing()
