I mean, come on, there are only two states. There will never be a third state. Instead of writing in my code: TermTextBox.IsVisible = MyBoolVar; I have to write something like: TermTextBox.Visibility = (MyBoolVar ?

RTF in silverlight
Hi all, I've got the a bunch of RTF coming from a service call that needs to render. I have two options: Find a control that can render RTF or convert the RTF to something else on the server side that can be rendered natively. For option 1, it seems the new SL4 RichTextbox doesn't support RTF (unless I've missed the mechanism for importing RTF text into the control?). I've trialed the DevExpress tool but it fails to render RTF with tables. I'm currently pulling down the ComponentOne RichTextbox to see if it does any better. I've also tried option 2 - using a WPF rich textbox (in memory only) to load the RTF and then push out various output formats. It supports output to XAML but of course the XAML is not compliant with Silverlight. I have my fingers crossed for the component one control but I'm not hopeful. I was wondering if anyone had any other suggestions on how to approach this and if anyone has found a good RTF control for silverlight. Client side is SL4 and server side is .Net 4.0.

RE: RTF in silverlight
You're right to a degree. We get stuff in a variety of formats from different systems. Some are plain text, some are RTF, some are strongly typed classes of data, etc. So RTF is a source type that we have no control over. We also investigated the option of converting RTF to HTML and displaying that in a Html control (I tried all the control vendors controls here as well). Essentially they 'cheat' by putting a browser element into Silverlight. The result is that nothing can render over the top of the HTML; its always on top. In our case we do need menus to render over the HTML. There are other work-arounds for this problem but they degrade the user experience. PDF is possible; we could convert to PDF on the server side and return a link to the PDF file. However we are looking for a richer embedded experience where the content being displayed looks like it is part of the page. I'm not sure that we could achieve that with PDF. It's a shame that we're up to version 4 of SL and still have to make compromises. I'm too stubborn for that. :) However I also realise that it's a niche problem and SL can't accommodate all scenarios.

Its funny because there's lots of RichTextbox controls out there but very few actually support RTF (most have their own versions of WPF's FlowDocument instead). I suspect these issues are because different companies have different implementations of the specification. Plus the specification has many versions. Plus some writers/readers may be more tolerant to invalid control codes, while others are more strict. What the world needs is an RTF validator where you can post your RTF. I didn't know Silverlight supported XPS, I'll investigate that option. Thanks for the sample Carl, I actually need RTF though, including image data which is embedded in the RTF as binary.

Subject: Lots of bind/notify classes
Look Dave, I can see you're really upset about this. I honestly think you ought
to sit down calmly, take a stress pill, and think things over - HAL (2001)
I was wondering if anyone has found a nice way of creating/managing lots of
classes that are suitable for binding and implement INotifyPropertyChanged. As
you know, you have to keep coding properties like this:
public string CompanyName
{
get {return this.companyNameValue;}
set
{
if (value != this.companyNameValue)
{
this.companyNameValue = value;
NotifyPropertyChanged(CompanyName);
}
}
}
You can create a simple base class to factor out the event, but not much else,
as there is no way I know of to intercept any arbitrary property setter and add
custom processing. Is that right?! Coding the above skeleton dozens or hundreds
of times gets tedious and I'm hoping there's a better way. I did consider using
a T4 generator to spit out the classes, but that's an obtuse way around the
problem and will require extra research time (but I see others have done it
already).
I have dozens of existing classes with dozens of properties and I'd like to use
them for binding, but I'd have to expand every property to be like the same
above, which would be hell.

Basically, we are running 32-bit Windows XP. The machines have anywhere between 2 and 4GB RAM. Everyone in the team gets System Out Of Memory Exceptions. When that happens, you have wasted the compile time, and then you have to shut down VS2010, start it up, then open up the solution. The solution has a significant number of projects in it. Apparently this problem only happens in 32-bit windows. So for the whole restart process, we have assigned 10 minutes to this procedure. Next we have logged the total crash time for our team of 7 developers (some days people were away, but it ultimately doesn't matter). The times lost are as follows: 14th 240 mins 15th 100 mins 18th 120 mins 19th 60 mins 20th 200 mins 21st 100 mins 22nd 140 mins we have assigned an arbitrary value against the times of $100/hour. So the loss of productivity is 16 hours @ $100/hour = $1600. Hopefully soon these figures will become a significant enough figure to justify an upgrade!

RE: Decoupling from RIA services
Hi David, We are using RIA and a standard ViewModel takes an IRepositoryT where T : Entity. When I want to track lists of items I use ObservableCollectionT as well and add it to the EntitySet if I want it commited to the database. Under the hood, an IRepositoryProduct and IRepositoryCategory will use the same domain context however we are in the process of adjusting this to use the same domain context only per ViewModel (ie unit of work) and this is managed by the IOC container. However I never really need to create NEW entity sets and was unsure how to answer your question. Usually with .Include(Products) you would get all the products with a category, or at least an empty entity set if there are none, and you can still add to that existing entity set on the Category entity.

Lambda expressions are serialisable with the right serialiser. you could
have a custom service method that takes a string as input which happens to
be the serialised lambda.
Deserialise it and apply the lambda to your entity model and then return the
results.

Subject: DataGridCheckBoxColumn
So I bind some DataGrid columns and one of them is a bool which corresponds to
a DataGridCheckBoxColumn. It all displays nicely and I get excited.
Then I notice that clicking the CheckBox cell puts it in edit mode, then I
click it again to change the value.
Then I notice that the binding change doesn't fire until I press Enter or Tab
or whatever to change focus. So it takes 3 gestures to change a value in a
CheckBox column. This is unacceptable for this app.
I see many people complain about the first quirk and suggest you use a template
column or more code and tricks as a workaround, but it all looks fragile,
unreliable and I can see myself burning another few hours of unpaid time and it
all probably won't work anyway.
No one seems to mention the focus problem. In WinForms you have to trap the
cell dirty change event and commit to the data source, but there is no
equivalent I can find. Nor does the UpdateSourceTrigger have a PropertyChanged
value.
So I'm stuffed again.

RE: DataGrid row button click
If you are using MVVM, then you can bind your button to a command on the object being bound to. From: ozsilverlight-boun...@ozsilverlight.com [mailto:ozsilverlight-boun...@ozsilverlight.com] On Behalf Of Greg Keogh Sent: Tuesday, 6 December 2011 8:04 PM To: 'ozSilverlight' Subject: DataGrid row button click Folks, I think I've outsmarted myself. I have a DataGrid bound with a template column containing a Button and it's all looking quite acceptable. Now I'm a bit flummoxed, as when one of the buttons is clicked I have to find out which object in the data source is behind the row containing the button. Unlike the WinForms grid, I have no RowIndex or similar property to help me, all I have are two properties on the Click event: sender and e.OriginalSource, which seem to be the same. I'll probably have to walk backwards up the control tree somehow to find the row and the item it's bound to, but I don't know how yet. Has anyone done this and got clues? I'll keep web searching in the meantime. Greg ___ ozsilverlight mailing list ozsilverlight@ozsilverlight.com http://prdlxvm0001.codify.net/mailman/listinfo/ozsilverlight
RE: DataGrid row button click (answered?!)
The row being acted upon is what actually has the Command object, so you're
already in the context of what you want to get information from
ViewModel:
Public ObservableCollectionFooModel Foos { get; set; }
FooModel:
public string Name { get; set; }
public RelayCommand AddWidget { get; set; }
View.xaml:
Datagrid ItemsSource={Binding Foos}
Datagrid.Columns
DataGridTemplateColumn Header=Execute!
DataTemplate
Button Command={Binding AddWidget} /
..
Something like that (pseudocode)

Subject: RE: DataGrid row button click (answered?!)
To find the DataGridCell that contains the clicked button I found that a
simple iteration up through the Parent properties of the sender eventually
reaches the cell. I don't go to the trouble of using the VisualTreeHelper as
the Parent property was enough in this case (I was doing that in a WPF app).
The DataContext property of the cell can luckily be cast to the object type
in the bound collection. I get the creeps about how fragile this all is,
having no strongly typed or nicely indexed values to work with. Are we sure
this is the way we're intended to do these things? I have this feeling of
unease that there is some technique that I'm missing, but I doubt it.
If you are using MVVM, then you can bind your button to a command on the
object being bound to.
How do you pass to the command handler something to identify the
button/row/object being acted upon?

RE: Skills
Hi Jasim, I know you said 'not javascript' but I think JS frameworks are really the order of the day. The ones I hear thrown around the most are: - jQuery - Backbone - Knockout - Spline But you said you're doing UX work.. are you looking at developer skills or UX skills to improve? HTML5 seems a reasonably safe choice either way. And ASP.Net MVC 4 beta was released today, so that could be a good place to look as well if you are a .Net dev.

RE: Tracing deployed app
Hi Greg, Presuming it's a Silverlight app, the first thing you can do is attach the debugger from your dev machine. That's what's great about Silverlight - it's a client side technology. So when you hit the website in prod, you're still running the app locally. Just use VS to 'Attach to process' and find the IE (or other browser) instance that has process type 'Silverlight'. Next to ensure your app is talking to the server (let's say via WCF or RIA services) you can use Fiddler to view the requests/responses. If you are getting failed requests, you can turn on 'Failed Request Logging' in IIS, this will show you what HttpModules are being called, etc. You can also use process monitor to see which DLLs are spun up via the IIS worker process on the prod box (assuming you are allowed to RDP to it). Naturally turning on profiling to ensure your database is being called from the server helps identify any connection problems there. Beyond that, assuming it is a pure code issue, then yeah.. logging. :) Log4Net is a good place to start. But this is all for server side of course (WCF, RIA). If you're thinking about logging for client side, well just attaching the debugger should do the trick most the time.

So I'm wondering what the easiest way is to log/trace what's happening inside the app on the live machine. In a previous app I had laced the code with my own logging which I put into a rolling array, and I had a button in the UI to show the lines in a list box. It works, but it's completely hand-written. I could add similar manual logging to my new app, but before I do that rather tedious work I was wondering if there are better ways of tracing/logging what's happening inside my SL4 app (inside IE8) on a live machine. It would be nice if I could add logging calls to my code, but let something else do the work of catching and displaying the data (like the Trace infrastructure). Perhaps there are tricks and techniques I'm not aware of. Greg ___ ozsilverlight mailing list ozsilverlight@ozsilverlight.com http://prdlxvm0001.codify.net/mailman/listinfo/ozsilverlight
