You may use Always or Never instead, which doesĮxactly what the names imply: Puts the item in the overflow menu all the time or prevents the item from ever being moved to the overflow menu. ![]() Item is put in the overflow menu if there's not enough room for it. The default value is AsNeeded, which simply means that a toolbar This is where the attached property ToolBar.OverflowMode comes into play. Items are less important than the others and some of them you might even want to have in the overflow menu all the time, no matter if there's space enough WPF even allows you to decide which items are suitable for overflow hiding and which should always be visible. You can see how it works on this screenshot, which shows the first example, but with a smaller window, thereby leaving less space for That if there's no longer enough room to show all of the buttons on the toolbar, WPF will put them in a menu accessible by clicking on the arrow to the OverflowĪs already mentioned, a very good reason for using the ToolBar control instead of just a panel of buttons, is the automatic overflow handling. Hover the mouse over the button to get a description of what it does, as demonstrated on the screenshot. This is especially important for thoseīuttons with only an icon, because the purpose of the button might not be clear from only looking at the icon. Notice how I've used the ToolTip property on each of the buttons, to add an explanatory text. On the thirdīutton, I combine an Image control and a TextBlock control inside of a StackPanel, to achieve both iconĪnd text on the button, a commonly used technique for buttons which are extra important or with a less obvious icon. Just have a look at this next example, where we do both: īy specifying an Image control as the Content of the first two buttons, they will be icon based instead of text based. WPF uses regular Button controls, adding icons to the toolbar items is very easy. While text on the toolbar buttons is perfectly okay, the normal approach is to have icons or at least a combination of an icon and a piece of text. below the other or even make them switch place. If you click and hold your left mouse button, youĬan now re-position the toolbar, e.g. ![]() Try running the example and place the cursor over the left part of one of the toolbars (the dotted area). WPF, contrary to the Cut, Copy and Paste commands, which WPF is capable of fully handling for us. In Code-behind, I make sure to handle the CanExecute event of the first three buttons, since that's not done automatically by Each contains some buttons and we use commands to In this example, I add a ToolBarTray to the top of the screen, and inside of it, two ToolBar controls. Look at the Menu chapter, or the articles on commands, for more information. ![]() We discussed this in the previous chapter and using commands definitely gives us some advantages. Notice how I use commands for all the buttons. Private void CommonCommandBinding_CanExecute(object sender, CanExecuteRoutedEventArgs e) Public partial class ToolbarSample : Window Namespace WpfTutorialSamples.Common_interface_controls Let's try a pretty basic example, to see what it all looks like: ToolBar controls inside of the ToolBarTray element. The ToolBarTray will handle stuff like placement and sizing, and you can have multiple This could in fact be a simple panel withīuttons on it, but by using the WPF ToolBar control, you get some extra goodies like automatic overflow handling and the possibility for the end-user toĪ WPF ToolBar is usually placed inside of a ToolBarTray control. ![]() The toolbar is a row of commands, usually sitting right below the main menu of a standard Windows application.
