Insert image to ControlImage(a kind of Content Control) in docx?

Hi everybody,

I have a problem as below:
- I insert a building block to document. The building block contains some content controls(Action, Label, ControlImage, …).
- I need to insert an image to ControlImage of the building block by Aspose Word.

Can Aspose word do that?

Thanks and best regards!


Thanks for your request.

You can use DocumentBuilder.InsertImage method to insert Image. For instance the following code demonstrates how you can insert Image into Content control:

// Open the document.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

Document doc = new Document("C:\\Temp\\in.doc");

// Create DocumentBuidler object, it will help use to insert Image.

DocumentBuilder builder = new DocumentBuilder(doc);

// Get content contorl where you would like to insert Image.

// Currently there is no way to identify content controls by title or tag,

// so to demonstrate the technique I just get the first SDT

StructuredDocumentTag sdt = (StructuredDocumentTag)doc.GetChild(NodeType.StructuredDocumentTag, 0, true);

// Remove old content from the SDT


// Now, create an empty paragraph and append it to the content control

sdt.AppendChild(new Paragraph(doc));

// Move DocumentBuilder cursor to the first child of SDT (newly created paragraph)


// Insert Image


// Save output


But unfortunately, currently there is no way to identify content controls by title or tag. We plan to provide more control over SDT in one of the nearest version of Aspose.Words. I linked your request to the appropriate issue. We will let you know once it is supported.

Hope this could help you to achieve what you need.

Best regards,

Thanks AndreyN for your reply.

Thanks aske012,

I found the the way to insert image to content control(Also base on your co-worker’s code, but change some things).
If you need to verify my changed code; please feel free to let me know, I’ll put the code.
