Remarks

Call the ShapeCollection.InsertTextBox method to add a text box to a document. Use the TextBox.Document property to access and modify text box content.

The following example creates a text box and specifies its content:

C#

Document document = wordProcessor.Document;
document.Unit = DevExpress.Office.DocumentUnit.Inch;
// Create a text box.
Shape myTextBox = document.Shapes.InsertTextBox(document.Range.Start, new RectangleF(1.5f, 1f, 1.5f, 0.5f));
// Specify the text box background color.
myTextBox.Fill.Color = System.Drawing.Color.WhiteSmoke;
// Draw a border around the text box.
myTextBox.Line.Color = System.Drawing.Color.Black;
myTextBox.Line.Thickness = 1;
// Modify text box content.
SubDocument textBoxDocument = myTextBox.ShapeFormat.TextBox.Document;
textBoxDocument.AppendText("Text box");
CharacterProperties cp = textBoxDocument.BeginUpdateCharacters(textBoxDocument.Range.Start, 4);
cp.ForeColor = System.Drawing.Color.Orange;
cp.FontSize = 24;
textBoxDocument.EndUpdateCharacters(cp);

VB.NET

Dim document As Document = wordProcessor.Document
document.Unit = DevExpress.Office.DocumentUnit.Inch
' Create a text box.
Dim myTextBox As Shape = document.Shapes.InsertTextBox(document.Range.Start, New RectangleF(1.5F, 1F, 1.5F, 0.5F))
' Specify the text box background color.
myTextBox.Fill.Color = System.Drawing.Color.WhiteSmoke
' Draw a border around the text box.
myTextBox.Line.Color = System.Drawing.Color.Black
myTextBox.Line.Thickness = 1
' Modify text box content.
Dim textBoxDocument As SubDocument = myTextBox.ShapeFormat.TextBox.Document
textBoxDocument.AppendText("Text box")
Dim cp As CharacterProperties = textBoxDocument.BeginUpdateCharacters(textBoxDocument.Range.Start, 4)
cp.ForeColor = System.Drawing.Color.Orange
cp.FontSize = 24
textBoxDocument.EndUpdateCharacters(cp)

Use the following properties to determine whether an existing drawing object is a text box:

• DrawingObject.Type is Shape;

• DrawingObject.ShapeFormat.HasText returns true.
