Hi,
In our application in a document (parent document) at a bookmark we are supposed to insert another document (child document). This child document is kind of a report from any third party application which will be in the form of a PDF, which in turn will be converted to Word before inserting into the parent document at the given bookmark. Then the converted Word document (child document) will inserted at the bookmark in the parent document. The child document, usually contains data in tabular format.
Now the issue is when we are inserting the child document data is not getting formatted properly. I am here by attaching a document for your reference. In the attached document, Section 1.1 is the parent document in which at the T4 bookmark we have inserted a child document. Child document content is all tables as you can see in the attached document. The entire table content is not visible.
Now if we select one table and center align the table we are able to see the entire content. So can we somehow center align the content of the document (child document) being inserted into a parent document using aspose. So that we can see the entire content.
or any other suggestion/solution for this kind of scenario where we can set something on the document being inserted or format it after the document is inserted into a parent document.
Please advice.
Regards,
Suguna
Hi
Thanks for your inquiry. Could you please attach your input documents and the code here for testing? I will check the issue on my side and provide you more information.
Best regards,
Thanks for the prompt reply. Here are the inputs which you needed.
- Attached “15e44b3c1283dd6ee2c7ff2_1307_5.doc” is the parent document where at the T4 bookmark we have to insert a child document
- Attached “lack_of_efficacy.doc” is the child document which we want to insert
Below is the code :
Insert Method
public static Document insertDocumentAfterBookMark(Document mainDoc, Document tobeInserted, String bookmark) throws Throwable

// check maindoc

return null;
// check to be inserted doc

return mainDoc;
synchronized(mainDoc)
{

synchronized(tobeInserted)
{
// check bookmark and then process
if (bookmark != null && bookmark.trim().length()> 0)
{
Bookmark bm = mainDoc.getRange().getBookmarks().get(bookmark);
if (bm != null)
{
// Clear the existing content at the bookmark
removeBookmarkContent(bm, mainDoc);
// Move cursor to bookmark and insert paragraph break
mainDocBuilder.moveToBookmark(bookmark);
mainDocBuilder.writeln();
// Content of tobeInserted document will be inserted after this node
Node insertAfterNode = mainDocBuilder.getCurrentParagraph().getPreviousSibling();
// insert the document at the bookmark
insertDocumentAfterNode(insertAfterNode, mainDoc, tobeInserted);
}
}
else
{
// if bookmark is not provided, add the document at the end

Do let me know if you need anything else.
Hi
Thank you for additional information. I think in your case you can use the code like the following to center the table:
// Open the document.
Document dstDoc = new Document("15e44b3c1283dd6ee2c7ff2_1307_5.doc");
Document srcDoc = new Document("lack_of_efficacy.doc");
// Get all rows
NodeCollection rows = srcDoc.GetChildNodes(NodeType.Row, true);
// Loop through all rows.
foreach(Row row in rows)
{
row.RowFormat.Alignment = RowAlignment.Center;
}
// And then insert srcDoc document in to the dstDoc document
Hope this helps.
Best regards,
Thanks a lot! Its working.
