Choose Toolbox Items Dialog Box (Visual Studio)
The Choose Toolbox Items dialog box displays tabbed panes listing components that are recognized on your local computer. You can use the Choose Toolbox Items dialog box to select or remove components, and to add items to the Toolbox or remove items from it. To open this dialog box, select Choose Toolbox Items from the Tools menu, or right-click on the Toolbox and select Choose Items from its shortcut menu.
The Choose Toolbox Items dialog box, named Customize Toolbox in previous versions of Visual Studio, replaces the former Components dialog box in Visual Basic. In other applications, the Choose Items command to access this dialog box might be located elsewhere, for example, on the shortcut menu of the document being edited.
To sort the items displayed on a tab of the Choose Toolbox Items dialog box, click any column header. To add an item to the active Toolbox tab, select the check box next to it. To remove an item from the Toolbox, clear its check box. When you choose OK, any items checked that are not already in the Toolbox will be added, and any items whose check boxes have been cleared will be removed from the Toolbox.
The component files on your computer are not affected when Toolbox icons for them are added or removed.
By default, the integrated development environment (IDE) adds the following tabbed panes of components to the Choose Toolbox Items dialog box:
Because the Choose Toolbox Items dialog box is extensible, you might also see other tabbed panes of components added by Visual Studio Add-in projects or by external applications and packages.
Before you add a custom control to the Toolbox, always verify the trustworthiness of the control by reviewing the publisher information or digital signature for the control.
