    I will prefer the way shown by Beatriz, since that is functionality already in-built into WPF, so why write my own attached property for it

    I want to see Silverlight provide support for binding controls to each other. Not everything that happens in the view has a representation in the model (I think that’s a fair statement).

    In Wpf, controls can be bound to each other, how could we do this declaratively in Silverlight.

    Thanks, I found this very helpful for thinking about how to split my code between the WPF Xaml and C# code behind, and what would be the best way to trigger different show/hide states in my UI.

    Sifting through 5 years of posts strewn across vast seas of geek broken english, 2 days lost in space, stranded on giligans island, before I got to this gem. Is it me or is it xaml? Best damn trigger explanation ever!

    David, I don't know if you'll see this but… Now I want to change the Beatriz type solution into this:


    <QuickTrigger Target='Window.Processing=True' Property='IsEnabled' Default='True' Value='False'/>

    Any thoughts about how to implement this concise (although admittedly more restrictive syntax) so that it "expands" into the code above (along with the <Button.Style> element etc)?

    Thankful CluelessNewbie,

    Thanks for the kind words! 🙂

    If you're looking for something like a pre-processor, XAML doesn't have that. Some folks run the C pre-processor on their XAML files, but that's pretty custom and I've never gone there myself. But if you're looking to implement that functionality in a more natural manner, you might look at creating a custom markup extension or maybe an attached behavior (via an attached DependencyProperty). A web search of either phrase should turn up some good examples and help you decide which is more like what you have in mind.

    Hope this helps!

    Hello. I can not make ajax toolkit combine script work. I really need help. This is the topic i made at official forums :…/1

    Furkan Gozukara,

    Everything I know about using the AJAX Control Toolkit for script combining can be found here:…/script-combining-made-easy-overview-of-the-ajax-control-toolkit-s-toolkitscriptmanager.aspx…/script-combining-made-better-overview-of-improvements-to-the-ajax-control-toolkit-s-toolkitscriptmanager.aspx

    As the note at the top of the original post says, this functionality is now available from ASP.NET itself – that's documented here:…/Combining%20Client%20Scripts%20into%20a%20Composite%20Script.ashx

    You'll probably want to use the built-in support if possible because it's likely to be easier and more supported. 🙂

    Hope this helps!
