  1. POExpose multiple command in WPF user control
    text
    copied!<p>A better explanation, I hope:</p> <ul> <li>I have a toolbar with 3 buttons on it, all three bound to a Command (including a CommandParameter)</li> <li>this toolbar is used on several screens</li> <li>the xaml of the toolbar is exactly the same over all those screens</li> </ul> <p>I want to remove the toolbar instance and replace it with a user control that provides 3 commands, so I can keep the bindings in each screen. The plan is to later change the toolbar functionality, but the external programming interface (namely, 3 commands) is the same. </p> <p>So: </p> <ul> <li>I created a user control, and created 3 sets of dependency properties for each command (OneCommand, OneCommandParameter, OneCommandTarget) so I can use these for the binding.</li> <li>I moved the toolbar xaml inside the user control xaml.</li> <li>I modified the bindings on the toolbar buttons to bind to the intristic user control properties</li> <li>on each screen (or really, only the first for now) I replaced the original toolbar with the user control,binding the new properties to the correct commands.</li> </ul> <p>The control shows, but the buttons don't work. That's about it. </p> <p>-- </p> <p>Original explanation - not so clear:</p> <p>I have a WPF user control encapsulating a number of buttons. Previously, the control was a Toolbar with a number of buttons on it, but since I need exact the same functionality on a number of screens, I refactored the toolbar into a custom control.</p> <p>However, I'd like to keep the command bindings of the original buttons. </p> <ul> <li>I created 3 sets of dependency properties (XCommand, XCommandParameter and XCommandTarget) on the usercontrol. </li> <li>In the user control xaml I bind the "real" buttons to those properties (each button to each set of properties). </li> <li>Where I use the usercontrol, I bind the new properties to the real command bindings.</li> </ul> <p>In essence, I want to keep the ICommandSource functionality for each "command" that the user control exposes. However, this dual databinding scenario doesn't seem to work, or I'm doing something wrong. :)</p> <p>Is there a better way to do this? All I need is to "bridge" the commands from outside the control to the inner buttons so the Execute and CanExecute functionality remains. </p>
