The following procedure shows how to create a user control in an Excel project. It also adds a button to the user control that writes text to a worksheet cell when it is clicked.
To create the user control
Open your Excel workbook or template project in Visual Studio.
On the Project menu, click Add New Item.
In the Add New Item dialog box, select Actions Pane Control, name it HelloControl, and click Add.
You can alternatively add a User Control item to your project. The classes generated by the Actions Pane Control and User Control items are functionally equivalent.
From the Windows Forms tab of the Toolbox, drag a Button control to the control.
If the control is not visible in the designer, double click HelloControl in Solution Explorer.
Add the following code to the Click event handler of the button.
In C#, you must create an event handler for the Button. You can place this code in the HelloControl constructor. For more information about creating event handlers, see How to: Create Event Handlers in Office Projects.
To show the actions pane, add the user control to the Controls property of the ThisWorkbook.ActionsPane field.
