I recently discovered CompositeCommand and find it works great for this scenario. It's part of Prism, but I just ripped it out since I don't use Prism.
https://prism.svn.codeplex.com/svn/V1/spikes/AGCompositeApplicationLibrary/AGComposite.Wpf/Commands/CompositeCommand.cs[^]
The toolbar will bind to a static CompositeCommand (i.e. in something like a GlobalCommands.cs) and then a view would attach to it with a RelayCommand. Something like:
GlobalCommands.SaveCommand.RegisterCommand(SaveCommand);
Multiple views can attach to the same command and all get notified when the button is clicked. The one gotcha though is the IActiveAware portion. Your ViewModelBase class needs to be tweaked to properly set the IsActive flags in the commands somehow.
Basically the way the CompositeCommand works is that say vmA and vmB attach... by default, the button will only enable if both return true for canExecute. By setting the IsActive flag on the commands properly, you can make it work in a way where the inactive commands are ignored. For example, if vmA.SaveCommand is not active, only vmB.SaveCommand will get the canexecute/execute calls.

Just curious, what does your moniker, 'SledgeHammer' refer to?
Could it be this?>>[^]

1) usercontrol.xaml.cs
public event RoutedEventHandler CustomClick;
private void btn_Click(object sender, RoutedEventArgs e)
{
if (CustomClick != null)
CustomClick(this, new RoutedEventArgs());
}
2)MainWindow.xaml
<controls:Button CustomClick="btn1_CustomClick" ButtonText="Click Here" Name="btn1" Margin="61,105,93,128"></controls:Button>
3)MainWindow.xaml.cs
private void btn1_CustomClick(object sender, RoutedEventArgs e)
{
MessageBox.Show("Custom control CLicked");
}
Click Event Not working for mybutton

|

So have you set breakpoints in the debugger and determined which part of the process isn't happening as you expect?
The CustomClick event in usercontrol.xaml.cs or the btn1_CustomClick in MainWindow.xaml.cs ?

what is the silver light application? where we can use it..?

Silverlight is a plugin, similar to Flash, that allows you to run richer web based applications. It's named after my good friend David Silverlight.

Oh yes indeedy. Just think, someday I may be telling people I knew the other, other Mycroft Holmes.

Silverlight is, as Pete said correctly, something like the Microsoft-Version of Flash. However, Microsoft has abandoned the technology, meaning that they are not going to support it for a long time. Therefore Silverlight should be left aside in favor of trqaditional Web technologies, as Javascript, HTML etc. are.

Apart from its just plugin it is used to create Rich UI, games and media based application on internet. It works at client side so there is lot saving of network bandwidth until you are not requesting any data to the server.

Wat, you imply the data is on the client - wrong, the UI and presentation code is on the client, the data is still requested from the server - but only the data.
I'm pretty sure there is some saving in bandwidth but I don't think it is a huge amount.

Please read it correct. I said it works on client side. Again it depends on where you store the data if its in database it may be in server. However we may save data in-memory collections as well which will be reside in client side. It totally depends on requirement.

And where does the data come from so you can save it in a local collection.
As I ONLY do LOB projects I may be missing something as ALL my data is stored in a database and has to be dragged out of the server.

I am looking at building a very simple schedule display layout something like the telerik TV schedule[^]. Basically a row header with multiple textblock fields and 1 month on a grid display that show a max of 1 event per day per row (no scheduling required).
Both the ScheduleView and PivotGrid are way over the top for what I want to achieve, but between the templated row header and the dynamic date columns I can't decide which control to use.

Why not just use that one? Easier then writing your own. If I was bored and wanted to write my own...
The left two columns would each be an ItemsControl styled with a vertical font and some borders.
The top row would be another ItemsControl styled with the time and tick marks, etc.
The grid would be 2 ItemsControls... one for the rows that contains another ItemsControl for the columns.
I'd package the control to hide all that though from the developer.
I wouldn't really reuse any control besides the ItemsControl. Doesn't seem like there is much functionality that can be reused from other controls.

Both the controls are monsters for something very simple. I don't need the row and column grouping, the vertical text is not required just the data laid out in a similar structure.
I was going to "I have decided to create a model of objects (RowHeader object and 31 DateEvent objects), I can then bind that to a templated gridview."

However this idea got me to thinking more sensibly - thank you.

I want to make an windows 8.1 store app(can be desktop but prefer store).
I know the following languages :
visual basic 2012(win rt)(preferable)
visual c++( not so good at it)
i have to make the beta fast
PROGRAM:-
->a interactive full screen homepage with 3 buttons and settings in the charm bar
HOME PAGE buttons:-
->1st button: record screen: records the desktop and other win 8 apps with webcam support and audio from mic
->2nd button: Edit video: more like mixing. you can drag-drop video to timeline(like windows movie maker) and 2 channel audio(one for voice and one for song)
->3rd button: upload video: push the video to the web as mp4 or avi at youtube or facebook or save them to disk
VOICE RECOGNITION:-
(optional) at the home screen when user say some command like 'program run record' or 'program edit video', the program does the same.
i want some leads...i have no experience in intensive, professional programming but i want to do so.
i would really appreciate if you tell me what i have to do,
specifically:
things that are easy,
things that need some stress
and work on!
Thanks in advance

But I have to scroll the carousel by code!
So, I'm asking your help on:
1) Either, how to invoke the "Interaction.Triggers" by code
2) Or, how to implement (by code) a Storyboard to browse from 1 "pathListBox.StartItemIndex" to another (and therefore deleting all the "<i:interaction.behaviors>" code"
Thanks very much for your help!!
PS: you can copy/paste the code to test, it should work out of the box!

Test is observablecollection, i am binding controls in Test. It has 20 controls, all 20 controls are displaying vertical, i want to display it in 2 columns(10 controls for each columns).
<ItemsControl x:Name="itemsControl" Canvas.Left="{Binding SetPosition}" ItemsSource="{Binding Test}">
</ItemsControl>

Where's your Canvas.Top property? You're only setting the Left here.
