Spire.Doc supports to insert a picture to text box as a background image or as a part of body content. This article demonstrates how to achieve these purposes through following code snippets.
Part 1. Insert Background Image to Text Box
using Spire.Doc;
using Spire.Doc.Documents;
using Spire.Doc.Fields;
using System.Drawing;
namespace InsertTextBox
{
class Program
{
static void Main(string[] args)
{
//Create a Word document
Document doc = new Document();
Section section = doc.AddSection();
Paragraph paragraph = section.AddParagraph();
//Append a Textbox to paragraph
TextBox tb = paragraph.AppendTextBox(120, 200);
//Set the position of Textbox
tb.Format.HorizontalOrigin = HorizontalOrigin.Page;
tb.Format.HorizontalPosition = 50;
tb.Format.VerticalOrigin = VerticalOrigin.Page;
tb.Format.VerticalPosition = 50;
//Set the fill effect of Textbox as picture
tb.Format.FillEfects.Type = BackgroundType.Picture;
//Fill the Textbox with a picture
tb.Format.FillEfects.Picture = Image.FromFile("Background.jpg");
//Save to file
doc.SaveToFile("InsertBackgroundImage.docx", FileFormat.Docx2013);
}
}
}

Part 2. Insert Image to Body of Text Box
using Spire.Doc;
using Spire.Doc.Documents;

namespace InsertTextBox
{
class Program
{
static void Main(string[] args)
{
//Create a Word document
Document doc = new Document();
Section section = doc.AddSection();
Paragraph paragraph = section.AddParagraph();
//Append a Textbox to paragraph
TextBox tb = paragraph.AppendTextBox(140, 250);
//Set the position of Textbox
tb.Format.HorizontalOrigin = HorizontalOrigin.Page;
tb.Format.HorizontalPosition = 50;
tb.Format.VerticalOrigin = VerticalOrigin.Page;
tb.Format.VerticalPosition = 50;
//Insert an image to body of Textbox
Paragraph para1 = tb.Body.AddParagraph();
Image image = Image.FromFile("Shakespeare.jpg");
DocPicture picture = para1.AppendPicture(image);
para1.Format.AfterSpacing = 8;
para1.Format.HorizontalAlignment = HorizontalAlignment.Center;
//Insert text to body of Textbox
Paragraph para2 = tb.Body.AddParagraph();
TextRange textRange = para2.AppendText("(26 Apr.1564–§C23 Apr.1616) English poet, playwright, and actor, widely regarded as the greatest writer in the English language and the world's pre-eminent dramatist.");
textRange.CharacterFormat.FontName = "Cambria";
textRange.CharacterFormat.FontSize = 9;

Set "Commit selected value immediately" property for ComboBox field and ListBox field
2017-04-12 09:06:28 Written by KoohjiWhen we operate the ComboBox field and ListBox field on PDF files, we can set the options for Dropdown Properties. This article will focus on how you how to set "Commit selected value immediately" property for ComboBox field and ListBox field. We will divide into two parts for how to set the property of "Commit selected value immediately", one is for the existing field on PDF and the other is for the new field added to the PDF file.
The following code is for how to set "Commit selected value immediately" property for the existing ListBox field on PDF:
//create a PDF document and load the document from file
PdfDocument pdf = new PdfDocument();
pdf.LoadFromFile("FormField.pdf");
//get the existing form
PdfFormWidget fw = pdf.Form as PdfFormWidget;
//get the ListBox field and set the field of CommitOnSelChange property as true
if (fw != null)
{
for (int i = 0; i < fw.FieldsWidget.Count; i++)
{
if (fw.FieldsWidget[i] != null)
{
if (fw.FieldsWidget[i] is PdfListBoxWidgetFieldWidget)
{
(fw.FieldsWidget[i] as PdfListBoxWidgetFieldWidget).CommitOnSelChange = true;
}
}
}
}
pdf.SaveToFile("Result.pdf");
The following code is for how to set the property of "Commit selected value immediately" for ComboBox field when we add a new ComboBox field on PDF:
using (PdfDocument pdf = new PdfDocument())
{
PdfPageBase page = pdf.Pages.Add();
//add a new ComboBox Field and add data to it
PdfComboBoxField combo = new PdfComboBoxField(page, "ComboBox");
combo.Bounds = new RectangleF(20, 20,60, 20);
PdfListFieldItem item1 = new PdfListFieldItem("First", "1");
PdfListFieldItem item2 = new PdfListFieldItem("Second", "2");
combo.Items.Add(item1);
combo.Items.Add(item2);
//set the field of CommitOnSelChange property as true
combo.CommitOnSelChange = true;
pdf.Form.Fields.Add(combo);
pdf.SaveToFile("Result2.Pdf");
}

A nested table is one table placed inside of another, where the larger table functions as a container for the smaller one. Nested tables allow you to arrange different sets of data in groups to show clients.
This article presents how we can create a nested table using Spire.Doc in C#.
Step 1: Create a new PDF document and add a section to it.
Document doc = new Document(); Section section = doc.AddSection();
Step 2: Add a table to the section.
Table table = section.AddTable(true); table.ResetCells(2, 3);
Step 3: Adjust the column with.
table.Rows[0].Cells[0].Width = table.Rows[0].Cells[2].Width = 50F; table.Rows[1].Cells[0].Width = table.Rows[1].Cells[2].Width = 50F; table.AutoFitBehavior(AutoFitBehaviorType.wdAutoFitWindow);
Step 4: Insert content to the cells of the table.
table[0, 0].AddParagraph().AppendText("SI.No.");
string text = "Earthwork excavation for foundation of buildings, water supply, "
+ "sanitary lines and electrical conduits either in pits or in "
+ "trenches 1.5m and above in width, in ordinary soil not exceeding "
+ "1.5m in depth including dressing the bottom and sides of pits and "
+ "trenches, stacking the excavated soil clear.";
table[0, 1].AddParagraph().AppendText(text);
table[0, 2].AddParagraph().AppendText("Qty");
Step 5: Insert a nested table to the cell (first row, second column).
Table nestedTable= table[0, 1].AddTable(true); nestedTable.ResetCells(3, 4); nestedTable.AutoFitBehavior(AutoFitBehaviorType.wdAutoFitContents);
Step 6: Add content to nested cells.
nestedTable[0, 0].AddParagraph().AppendText("SI.No.");
nestedTable[0, 1].AddParagraph().AppendText("Item");
nestedTable[0, 2].AddParagraph().AppendText("Qty");
nestedTable[0, 3].AddParagraph().AppendText("Rate");
nestedTable[1, 0].AddParagraph().AppendText("1");
nestedTable[1, 1].AddParagraph().AppendText("Sand");
nestedTable[1, 2].AddParagraph().AppendText("30");
nestedTable[1, 3].AddParagraph().AppendText("45");
nestedTable[2, 0].AddParagraph().AppendText("2");
nestedTable[2, 1].AddParagraph().AppendText("Cement");
nestedTable[2, 2].AddParagraph().AppendText("30");
nestedTable[2, 3].AddParagraph().AppendText("50");
Step 7: Save the file.
doc.SaveToFile("Nested_Table.docx", FileFormat.Docx2013);
Output:
Full Code:
//create a new pdf document
Document doc = new Document();
Section section = doc.AddSection();
//add a table
Table table = section.AddTable(true);
table.ResetCells(2, 3);
//set column width
table.Rows[0].Cells[0].SetCellWidth(50F,CellWidthType.Point);
table.Rows[0].Cells[2].SetCellWidth(50F, CellWidthType.Point);
table.Rows[1].Cells[0].SetCellWidth(50F, CellWidthType.Point);
table.Rows[1].Cells[2].SetCellWidth(50F, CellWidthType.Point);
table.AutoFit(AutoFitBehaviorType.AutoFitToWindow);
nestedTable.AutoFit(AutoFitBehaviorType.AutoFitToContents);
//insert content to cells
table[0, 0].AddParagraph().AppendText("SI.No.");
string text = "Earthwork excavation for foundation of buildings, water supply, "
+ "sanitary lines and electrical conduits either in pits or in "
+ "trenches 1.5m and above in width, in ordinary soil not exceeding "
+ "1.5m in depth including dressing the bottom and sides of pits and "
+ "trenches, stacking the excavated soil clear.";
table[0, 1].AddParagraph().AppendText(text);
table[0, 2].AddParagraph().AppendText("Qty");
//add a nested table to cell(first row, second column)
Table nestedTable= table[0, 1].AddTable(true);
nestedTable.ResetCells(3, 4);
nestedTable.AutoFitBehavior(AutoFitBehaviorType.wdAutoFitContents);
//add content to nested cells
nestedTable[0, 0].AddParagraph().AppendText("SI.No.");
nestedTable[0, 1].AddParagraph().AppendText("Item");
nestedTable[0, 2].AddParagraph().AppendText("Qty");
nestedTable[0, 3].AddParagraph().AppendText("Rate");
nestedTable[1, 0].AddParagraph().AppendText("1");
nestedTable[1, 1].AddParagraph().AppendText("Sand");
nestedTable[1, 2].AddParagraph().AppendText("30");
nestedTable[1, 3].AddParagraph().AppendText("45");
nestedTable[2, 0].AddParagraph().AppendText("2");
nestedTable[2, 1].AddParagraph().AppendText("Cement");
nestedTable[2, 2].AddParagraph().AppendText("30");
nestedTable[2, 3].AddParagraph().AppendText("50");
//save
doc.SaveToFile("Nested_Table.docx", FileFormat.Docx2013);
