Get the context, angular, ui-router, nothing special, a root view built with 3 named ui-views.
so in index.html we have
<body>
<div ui-view='left'>
<div ui-view='center'>
<div ui-view='right'>
</body>
my route looks like
$stateProvider
.state('main', {
url: '/',
views: {
'left': {templateUrl: 'foo.html'},
'center': {templateUrl: 'bar.html'},
'right': {templateUrl: 'xyz.html'}
}
})
.state('main.b', {
url: '/b',
params: { foo: {value: 'bar'} }
views: { 'right@': {templateUrl: '123.html'} } // I wish to update $stateParams in 'left@' view
})
.state('main.c', {
url: '/c',
params: ...
views: { 'left@': ..., 'center@': ..., 'right@': .. }
});
Is there a way in going to b state to update the $stateParams in the 'center' and 'left' view?? I can get it using a service but i need to add a $watch to the variable I need and it looks a little bit hacky to me.
Going into c state I can actually get what I want, but the view is reloaded, and i wish to avoid this behaviour cause i have a canvas in the 'left' view.

You could use the following to go to a specific route without reloading the views:
$state.go('.', {parm1: 1}, {notify: false});
The last object literal represents the options which you can pass along to go. If you set notify to false, this will actually prevent the controllers from being reinitialized. The . at the beginning is the absolute state name or relative state path you wanna go to.
The important thing is the notify though.

I think that using "Dynamic params" is now a better solution:
When dynamic is true, changes to the parameter value will not cause the state to be entered/exited. The resolves will not be re-fetched, nor will views be reloaded.
$stateProvider.state('search', {
url: '/search?city&startDate&endDate',
templateUrl: 'some/url/template.html',
params: {
city: {
value: 'Boston',
dynamic: true
}
}
}
and then:
$state.go('.', {city: 'London'});

Quoting @christopherthielen from https://github.com/angular-ui/ui-router/issues/1758#issuecomment-205060258:
using notify: false is almost never a good idea, and is now deprecated. Use reloadOnSearch if you must.
You can also try dynamic parameters in the 1.0 version (currently 1.0.0-alpha.3). In your state, configure a parameter as dynamic and implement the uiOnParamsChanged callback :
.state('foo', { url: '/:fooId', params: { fooId: { dynamic: true } }, controller: function() { this.uiOnParamsChanged = function(changedParams, $transition$) { // do something with the changed params // you can inspect $transition$ to see the what triggered the dynamic params change. } } });
For a demo, have a look at this plunker: http://plnkr.co/edit/T2scUAq0ljnZhPqkIshB?p=preview
