Hii team,
How can i check the current sdt content is splited in two or more pages ?
Snippet :
Aspose.Words.Document doc = new Aspose.Words.Document(@"C:\\SDT_Check.docx");
var sdts = doc.GetChildNodes(NodeType.StructuredDocumentTag, true)
.Where(x => ((Aspose.Words.Markup.StructuredDocumentTag)x).Tag.StartsWith("Rangescop_"));

And I want to add bookmark to the before sdt first child of first page and next page.
@AlpeshChaudhari12345 You can use LayoutCollector to detect page index where some node starts or ends. In your case you can use code like the following to insert a bookmark into SDT at the beginning of each page of SDT content:
Document doc = new Document(@"C:\Temp\in.docx");
LayoutCollector collector = new LayoutCollector(doc);
StructuredDocumentTag sdt = doc.GetChildNodes(NodeType.StructuredDocumentTag, true).Cast<StructuredDocumentTag>()
.Where(x => x.Tag.StartsWith("Rangescop_")).FirstOrDefault();
// Check page number wherre SDT starts and ends.
int sdtPageStart = collector.GetStartPageIndex(sdt);
int sdtPageEnd = collector.GetEndPageIndex(sdt);
if (sdtPageStart != sdtPageEnd)
{
// Split all Run nodes in the SDT to make them not more than one word.
List<Run> runs = sdt.GetChildNodes(NodeType.Run, true).Cast<Run>().ToList();
foreach (Run r in runs)
{
Run current = r;
while (current.Text.IndexOf(' ') >= 0)
current = SplitRun(current, current.Text.IndexOf(' ') + 1);
}
// Now update page layout and reset LayoutCollector to work with the updated document model.
collector.Clear();
doc.UpdatePageLayout();
NodeCollection updatedRuns = sdt.GetChildNodes(NodeType.Run, true);
int currentPageIndex = -1;
// Loop through the runs and detect where page index changes.
for (int i = 0; i < updatedRuns.Count; i++)
{
// Insert bookmark before the Run where page index changes.
Node currnetRun = updatedRuns[i];
int runPageIndex = collector.GetStartPageIndex(currnetRun);
if (runPageIndex != currentPageIndex)
{
BookmarkStart start = new BookmarkStart(doc, string.Format("sdt_start_{0}", runPageIndex));
BookmarkEnd end = new BookmarkEnd(doc, start.Name);
currnetRun.ParentNode.InsertBefore(start, currnetRun);
currnetRun.ParentNode.InsertBefore(end, currnetRun);
currentPageIndex = runPageIndex;
}
}
}
doc.Save(@"C:\Temp\out.docx");
private static Run SplitRun(Run run, int position)
{
Run afterRun = (Run)run.Clone(true);
run.ParentNode.InsertAfter(afterRun, run);
afterRun.Text = run.Text.Substring(position);
run.Text = run.Text.Substring(0, position);
return afterRun;
