This format is often used to transfer tabular data or spread sheet information. The available options provided by the TextDataFormat enumeration are: If the clipboard does not contain the specified type of text the return value is empty. This defines the type of data that's expected. The second overload requires an argument that contains a value from the TextDataFormat enumeration. If the clipboard is empty or contains information that cannot be represented as text, the returned string is empty. The parameterless version reads any text information from the clipboard and returns it in a string. We do this using the static GetText method. In the sample, we'll read the clipboard and set the Text property of the text box accordingly. To paste means reading the clipboard's contents and applying them within your software. Instead, you simply read data from, or write data to, the clipboard. When working with the Clipboard class the concepts of cut, copy and paste don't apply. If you decide to download the sample project using the link at the start of this article you'll see the form arranged as shown below: This button will copy the information from the clipboard into the text box. After clicking, the clipboard will contain the information in the text box but the text in the control will be unchanged. This button will copy the text from the text box. This button will cut the contents of the text box, removing the text and adding it to the clipboard. This button will clear the contents of the clipboard, freeing up the memory it would otherwise use. This text box will be the target for a paste function and the source of cut and copy operations. Once the project is initialised, we need to add five controls to the form. To begin, start Visual Studio and create a new Windows Forms Application project. We'll also see how to clear the contents of the clipboard entirely. In this article we'll examine the basic operations relating to cutting, copying and pasting text. The Clipboard class allows you to programmatically read and modify the clipboard's contents using various types of information, including plain or formatted text, audio clips, images and serialized object data. You can create this type of functionality using members of the Clipboard class, which is found in the namespace. ![]() ![]() ![]() You may wish to add a Copy button to such a form that, when clicked, copies all of the entered information as a single unit. For example, you may create a form that permits the user to enter a number of details about a product. Sometimes you will want to perform more complex operations or provide clipboard functionality for controls that do not normally support it. You can also right-click a text box and choose these operations from a context-sensitive menu. For example, text boxes support it using the keyboard combinations Ctrl-X, Ctrl-C and Ctrl-V for cut, copy and paste respectively. Many standard controls include clipboard functionality automatically. ![]() NET, you can read and manipulate clipboard information easily. When you are developing applications using. For example, whilst word processing you might cut a paragraph of text from a document and paste it into a different position. This makes it easy to transfer information between applications, or to reorganise or duplicate information within a single program. You can later paste the information from the clipboard into the same software that it generated it, or into a compatible program. Most Windows users are familiar with the use of the clipboard, which holds information that you have cut or copied from a program.
