Create Text Boxes in Word Documents Using C# and VB.NET

TextBox element is a type of a Shape element that contains the text. The textbox can contain multiple Block-level elements, such as Paragraphs and Tables.As in Word, you can easily adjust and resize text boxes in your documents with GemBox.Document using C# and VB.NET.

Textboxes can be inline (of InlineLayout type), in which case the position of the textbox is constrained to the lines of text on the page. Alternatively, they can be floating (of FloatingLayout type), in which case they can be positioned anywhere on the page.

You can read more about shapes and positioning on the Shapes and Layout help page.

The following example shows how you can create text boxes with different properties (such as Fill, Outline, etc.).
