Export the entire interface to PDF
I created a simple program that contains Labels and TextBoxes. I added a Button to export the entire interface with Labels and Textboxes to PDF
but I get this error message:
Unable to cast object of type 'System.Windows.Forms.Panel' to type
'iTextSharp.text.IElement'.,
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim pdfDoc As New Document()
Dim pdfWrite As PdfWriter = PdfWriter.GetInstance(pdfDoc, New FileStream("C:UsersWin 10Desktopsimple.pdf", FileMode.Create))
pdfDoc.open()
pdfDoc.Add(Panel1)
pdfDoc.Add(Panel2)
pdfDoc.Add(TextBox1)
pdfDoc.Add(TextBox2)
pdfDoc.Close()
End Sub
vb.net winforms

I changed the tagged language fromVBA
toVB.Net
. Different lnguages. You will probably need the render to Bitmaps your Controls. See Control.DrawToBitmap.

You will need to convert the controls to Bitmap images, then drop them into the PDF
.
I wrote this function that will take WinForms
controls, convert them to Bitmap and then into iTextSharp.text.Image
formats that can then be placed inside of a PDF
.
Function ControlToPDFImage(ControlToConvert As Windows.Forms.Control)
Dim Bmp As Bitmap = New Bitmap(ControlToConvert.Width, ControlToConvert.Height)
ControlToConvert.DrawToBitmap(Bmp, New Drawing.Rectangle(0, 0, Panel1.Width, Panel1.Height))
Dim PDFImg As Image = iTextSharp.text.Image.GetInstance(Bmp, System.Drawing.Imaging.ImageFormat.Png)
Return PDFImg
End Function
So if you change your code to this, it should work:
pdfDoc.Add(ControlToPDFImage(Panel1))
pdfDoc.Add(ControlToPDFImage(Panel2))
pdfDoc.Add(ControlToPDFImage(TextBox1))
pdfDoc.Add(ControlToPDFImage(TextBox2))
this worked for me thanks

As a note,Control.DrawToBitmap
will not work with aRichTextBox
control. It will not give any errors, but the control's content will not be rendered. In this case, you'll need to take a screenshot of the control bounds. See the Graphics.CopyFromScreen method.
