New Post: Application with more than one Shell or Popup Windows with regions inside it

DCherubini — Mon, 20 May 2013 20:17:45 GMT

Hi,

As far as I know, I believe that a RegionAdapter should not have affect over controls injected into the region, but over the control that is being used as a region; although this could differ depending on the implementation of the RegionAdapter.

If you are using a custom RegionAdapter that is causing problems it would be helpful if you could share it with us along with a description of what controls you want to adapt an how you want to use the region, so that we can help you with it.

New Post: How to activate an existing order details view in StockTraderRI ?

fmartinez — Mon, 20 May 2013 18:49:56 GMT

Hi,

I'm not sure if I understand what you are trying to achieve. If what you want is to simply set the TransactionInfo from your orderDetailsViewModel, this is already being done in the code you provided before, since the property TransactionInfo from your orderCompositeViewModel will also set the same TransactionInfo for the orderDetailsViewModel, which comes through Dependency Injection in the OrderCompositeViewModel constructor. So if you want to pass tickerSymbol to your orderDetailsViewModel, you will just need to set the TransactionInfo using that tickerSymbol to your orderCompositeViewModel.

orderCompositeViewModel.TransactionInfo = new TransactionInfo(tickerSymbol, transactionType);

If you want to use TransactionInfo in a way that you can react and show details from an item, you could use a new TransactionType, since TransactionType is defined as:

public enum TransactionType
{
    Buy,
    Sell
}

If this doesn't help you or we misunderstood your scenario, it would be helpful if you could provide us more information about what you are trying to achieve.

Regards.

Hi,

Since Unity and MEF work different, you will need to do some modifications to the code, i.e. the way you declare Modules, so that your application can work with MEF. Changing the references is just the first step. To understand how you can make those changes, you can always check Prism documentation, since each of the documentation sections describes how to implement the same code with both Unity and MEF containers:

I have a full MVVM Prism pattern project where I am facing a problem, and i.e. when I am debugging code shows view model updating the property but view not showing these changes. My question is, is there a event or action or something that restrict to reflect the changes of property in PRISM ?

View A - contains user 2 controls and one of the user control is showing this issue where as one user control working fine. and most important is this is issue coming on 2nd load of the view.

New Post: Architecture in designing Login Page and the other screens using prism ,mvvm,wpf ,untity 3.0

Thanks a lot Martinez .

Can we follow this approach ?

The LoginView.xaml will not be a part of 'Shell.Xaml ',instead we created another view in the same project as 'shell.xaml'.whenever shell initializes we show the login dialog, once user eneters details and click on 'ok' based on dialog result we show the Mainwindow.showor attach mainwindow to shell. is this approach correct or do you see any issues.
Apart from this I also need your help in validating the attached flow. or suggest how many regions we require , first scrren has 3 regions and clicking on the button present on the first screen loads second screen which has different regions again , the same applies for third as well as foutrth.Need you suggestions in designing tha app,what all things should we consider and how should my shell.xaml look like, how many regions should i divide it into etc.

I was unable to attach the sample screen here.let me know your email so that i can frwd it.but in general,

Screen 1 : has
3 regions

StatusRegion
2.Userregion (which has tabcontrols with different views)
3.Todo region ,which has 2 regions.

Screen 2: clcik on button present in view presnt in useregion, this gets load ,it also has
1.Statusregion

Userdetailregion ,which has views contains userpic,details
It has userdataregion which has tabitems which has different grids contains data.
userdataregion also has a comments region at the end where user can add comments.

Same applies like screen 3 , where lciking on button on view in screen 2 ,
different views or regions get loaded.

How many regions in total my shell should be divided into, how can i ft in these many views..how should i navigate between them,
need suggestions for this type of applications.
Thanks in advance.let em know if you need more detail!

Krishna
