Get alias, tag and id of content controls in a Word document in C#
Content controls provide a way for you to design documents. When you add a content control to a document, the control is identified by a border, a title, and temporary text that can provide instructions to the user. According to Microsoft, content controls mainly benefit from two features:
- Prevent users from editing or deleting protected sections of a document.
- Bind parts of a document or template to data. You can bind content controls to database fields, managed objects in the .NET Framework, XML elements that are stored in the document, and other data sources.
Therefore, it is necessary for developers to get the properties of content controls when dealing content controls at run time. This article illustrates how to get all controls and their properties including alias, id and tag via Spire.Doc.
Firstly, check the test file that contains six content controls distributed in lines and a table. By default, the border and the title of the control do not appear if we don't click the protected section.
Test File:

Main Steps:
Step 1: Create a new Word document and load the test file.
Step 2: Create two lists to store tags which are distributed in lines and a table separately. Here, each content control will be identified by tag.
Step 3: Use foreach sentence to get all tags in the Word document.
Full Code:
static void Main(string[] args)
{
using (Document document = new Document(@"..\..\TestData\test.docx"))
{
StructureTags structureTags = GetAllTags(document);
List<StructureDocumentTagInline> tagInlines = structureTags.tagInlines;
string alias = tagInlines[0].SDTProperties.Alias;
decimal id = tagInlines[0].SDTProperties.Id;
string tag = tagInlines[0].SDTProperties.Tag;
List<StructureDocumentTag> tags = structureTags.tags;
alias = tags[0].SDTProperties.Alias;
id = tags[0].SDTProperties.Id;
tag = tags[0].SDTProperties.Tag;
}
}
static StructureTags GetAllTags(Document document)
{
StructureTags structureTags = new StructureTags();
foreach (Section section in document.Sections)
{
foreach (DocumentObject obj in section.Body.ChildObjects)
{
if (obj.DocumentObjectType == DocumentObjectType.Paragraph)
{
foreach (DocumentObject pobj in (obj as Paragraph).ChildObjects)
{
if (pobj.DocumentObjectType == DocumentObjectType.StructureDocumentTagInline)
{
structureTags.tagInlines.Add(pobj as StructureDocumentTagInline);
}
}
}
else if (obj.DocumentObjectType == DocumentObjectType.Table)
{
foreach (TableRow row in (obj as Table).Rows)
{
foreach (TableCell cell in row.Cells)
{
foreach (DocumentObject cellChild in cell.ChildObjects)
{
if (cellChild.DocumentObjectType == DocumentObjectType.StructureDocumentTag)
{
structureTags.tags.Add(cellChild as StructureDocumentTag);
}
else if (cellChild.DocumentObjectType == DocumentObjectType.Paragraph)
{
foreach (DocumentObject pobj in (cellChild as Paragraph).ChildObjects)
{
if (pobj.DocumentObjectType == DocumentObjectType.StructureDocumentTagInline)
{
structureTags.tagInlines.Add(pobj as StructureDocumentTagInline);
}
}
}
}
}
}
}
}
}
return structureTags;
}
public class StructureTags
{
List<StructureDocumentTagInline> m_tagInlines;
public List<StructureDocumentTagInline> tagInlines
{
get
{
if (m_tagInlines == null)
m_tagInlines = new List<StructureDocumentTagInline>();
return m_tagInlines;
}

Modify and Format Annotation in PDF in C#/VB.NET
Text annotation is frequently used in PDF for creating a comment or explaining more about an item. Using Spire.PDF you can create a text mark-up annotation, edit an existing annotation and delete specified or all annotations. This article is aimed to demonstrate how to modify and format an existing text annotation in a PDF document.
Test File:

Changes we want to make:
- Modify the annotation text.
- Change the color of the annotation icon.
- Fix the annotation flag including its position, color, and type.
Code Snippet
Step 1: Create a new PDF document and load the test file.
PdfDocument pdf = new PdfDocument("test.pdf");
Step 2: Get the annotation from the document.
PdfAnnotation annotation = PdfAnnotationCollection.Create(pdf.Pages[0])[0];
Step 3: Set the text, border, color of the annotation and lock the annotation flag.
annotation.Contents = "Revised annotation"; annotation.Border.Width = 0.75f; annotation.Color = new PdfRGBColor(Color.White); annotation.Flags = PdfAnnotationFlags.Locked;
Step 4: Save and launch the file.
pdf.SaveToFile("result.pdf");
Process.Start("result.pdf");

Convert XLS to XLSM and Maintain Macro in C#, VB.NET
A file with the XLSM extension is an Excel Macro-Enabled Workbook file. For security reasons, XLS file or XLSX file does not enable macros by default. Thus, if you want to execute macros in Excel file, you need to convert XLS or XLSX to XLSM at the first place. In this article, I’ll introduce you how to convert XLS to XLSM with the macro maintained using Spire.XLS.
Here is the method:
Step 1: Create a new instance of Spire.Xls.Workbook class.
Workbook workbook = new Workbook();
Step 2: Load the test file and imports its data to workbook.
workbook.LoadFromFile("test.xls", ExcelVersion.Version97to2003);
Step 3: Save the workbook as a new XLSM file.
workbook.SaveToFile("result.xlsm", FileFormat.Version2007);
Full Code:
using Spire.Xls;
namespace Convert
{
class Program
{
static void Main(string[] args)
{
Workbook workbook = new Workbook();
workbook.LoadFromFile("test.xls", ExcelVersion.Version97to2003);
workbook.SaveToFile("result.xlsm", FileFormat.Version2007);
}
}
}
Imports Spire.Xls
Namespace Convert
Class Program
Private Shared Sub Main(args As String())
Dim workbook As New Workbook()
workbook.LoadFromFile("test.xls", ExcelVersion.Version97to2003)
workbook.SaveToFile("result.xlsm", FileFormat.Version2007)
End Sub
End Class
End Namespace
Test File:
As is shown in the picture, Excel automatically disables macro in XLS file.

Result:
No security warning in the converted XLSM file.

Prevent Page Breaks in Word Tables in C#
All too often, we start a table near the bottom of a page. Microsoft Word automatically places a page break in a table if a single row or several rows are too long to fit between the top and bottom margins of the page. So we'd rather the same row can be placed on one page or have the entire table on the next page instead of being broken over two pages. In this article, I'll introduce you two ways to avoid page breaks in Word tables via Spire.Doc.
Assume that we have a Word table like this (Row 2 splits to different pages), we may want to optimize the layout by the following two methods.

Method 1: Keep the entire table on the same page.
Step 1: Create a new Word document and load the test file.
Document doc = new Document("Test.docx");
Step 2: Get the table from Word document.
Table table = doc.Sections[0].Tables[0] as Table;
Step 3: Change the paragraph setting to keep them together.
foreach (TableRow row in table.Rows)
{
foreach (TableCell cell in row.Cells)
{
foreach (Paragraph p in cell.Paragraphs)
{
p.Format.KeepFollow = true;
}
}
}
Step 4: Save and launch the file.
doc.SaveToFile("Result.docx", FileFormat.Docx2010);
System.Diagnostics.Process.Start("Result.docx");
Output:

Use this sentence to replace Step 3, you'll get the layout as below:

Full C# Code:
Method 1
using Spire.Doc;
using Spire.Doc.Documents;
namespace PreventPageBreak
{
class Program
{
static void Main(string[] args)
{
Document doc = new Document("Test.docx");
Table table = doc.Sections[0].Tables[0] as Table;
foreach (TableRow row in table.Rows)
{
foreach (TableCell cell in row.Cells)
{
foreach (Paragraph p in cell.Paragraphs)
{
p.Format.KeepFollow = true;
}
}
}
doc.SaveToFile("Result.docx", FileFormat.Docx2010);
System.Diagnostics.Process.Start("Result.docx");
}
}

Remove borderline of textbox in Excel chart in C#, VB.NET
There is an article in the tutorials which demonstrates how to insert textbox with contents in Excel. Sometime back, a user of Spire.XLS wanted to know if it is possible to remove the borderline of the textbox that has been inserted in Excel chart. Yes, of course. This article focuses on delivering a solution to this issue.
In the following section, we're going to create two textboxes in the same chart, one textbox is built with borderline, the other one without. Then we can learn how to remove borderline using Spire.XLS by comparison.
Code snippet for remove borderline of textbox:
Step 1: Create a new instance of workbook.
Workbook workbook = new Workbook(); workbook.Version=ExcelVersion.Version2010;
Step 2: Create a new worksheet named "Remove Borderline" and add a chart to the worksheet.
Worksheet sheet = workbook.Worksheets[0]; sheet.Name = "Remove Borderline"; Chart chart = sheet.Charts.Add();
Step 3: Create textbox1 in the chart and input text information.
XlsTextBoxShape textbox1 = chart.TextBoxes.AddTextBox(50, 50, 100, 500) as XlsTextBoxShape;
Step 4: Create textbox2 in the chart, input text information and remove borderline.
XlsTextBoxShape textbox = chart.TextBoxes.AddTextBox(500, 50, 100, 500) as XlsTextBoxShape; textbox.Text = "The solution without borderline"; textbox.Line.Weight = 0;
Step 5: Save and launch the file.
workbook.SaveToFile("Sample.xlsx", ExcelVersion.Version2010);
Process.Start("Sample.xlsx");
Result:

Full code:

Worksheet sheet = workbook.Worksheets[0];
sheet.Name = "Remove Borderline";
// Add a chart to the worksheet
Chart chart = sheet.Charts.Add();
// Add the first text box (with visible border)
XlsTextBoxShape textbox1 = chart.TextBoxes.AddTextBox(50, 50, 100, 500) as XlsTextBoxShape ;
textbox1.Text = "The original with borderline";
// Add the second text box (border will be hidden)
XlsTextBoxShape textbox2 = chart.TextBoxes.AddTextBox(500, 50, 100, 500) as XlsTextBoxShape;
textbox2.Text = "The solution without borderline";
// Hide the border by setting line weight to 0
textbox2.Line.Weight = 0;
// Save the result file
workbook.SaveToFile("Sample.xlsx", ExcelVersion.Version2010);
Process.Start("Sample.xlsx");
}
