Add Excel Text Boxes in C# and VB.NET

TextBox elements are special rectangular areas that hold text. In GemBox.Spreadsheet TextBox elements are used to hold shape text content and you can access them via the ExcelShape.Text property.

The ExcelShape object allows you to specify the element's size, location, and geometry (for more information, see the Shapes example), while the TextBox object allows you to set the text content and text formatting.

The example below shows how to create and customize text boxes and their content, and add them to an Excel worksheet in C# and VB.NET.
