RE: Lots of bind/notify classes

[Steven Nagy]

I might add, that even if you don't want to introduce Post# then the simple 
base class + Resharper combination is pretty good.
For example, your base class has some methods for raising property changed 
events. Then your ViewModel needs a property for first name.
You use the "prop" code snippet, this expands out very quickly to:

public string FirstName { get; set; }

Then ALT+Enter with Resharper lets you convert to backing field in total 3 
keystrokes:

private string _firstName;
public string FirstName
{
get { return _firstName; }
set { _firstName = value; }
}

Then a single call to property changed:

private string _firstName;
public string FirstName
{
get { return _firstName; }
set { _firstName = value; PropertyChanged("FirstName"); }
}

Not so bad, very minimal keystrokes.

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.

RE: Lots of bind/notify classes

+1.  

 

I use snippets for this sort of stuff, which makes generating all that
code very easy.

 

The project I work on also uses a base class to hide the event.  It's
quite a large project, and I haven't seen it get in the way of doing
anything else.

 

I haven't tried the aspect idea (re:PostSharp).  I wonder how this would
affect Blendability?

Hi Greg,

 

I hear your pain and reflect it.

 

You could probably set up a method using PostSharp to automatically
create the necessary setter code, but that's provided you can introduce
PostSharp into your process.

 

The best I've managed is to set up a Visual Studio code snippet to help
create them quickly. I deferred doing that for a long time, but recently
got around to it and it does make things much less painful. But
unfortunately still far from ideal. Just grab the existing 'prop' code
snippet and expand it out from there. 'tis fairly simple to do and well
worth the effort.

 

ciao, Richard

RE: Images invisible (SOLVED)

[Greg Keogh]

Stephen, I own you a bottle of champagne, as you accidentally pointed out
what was wrong with my project.

 

Why was it using the file system I don't do that, I prefer to use HTTP
as it's more realistic. I didn't notice the file system path in the web
browser.

 

So sometime over the last couple of days, some configuration of my project
has changed, some defaults I dunno what, but by carefully putting all my
project settings back according to those of another working SL3 project it
has come good. VS has been crashing a lot, and I had to purge all the hidden
solution files recently, so that's probably broken my defaults.

 

So it couldn't load the images because I was running from the file system.
There's a warning for you!!

no no, its not in fiddler. you type it into your url address bar in your

if your normal url is "localhost/default.html" then you change it to read "
somesite.com/default.html"

I mean literally, letter for letter. use the actual words *somesite.com*, I
don't mean just any old name, I mean literally. :)
Put it in your browser.

you can ping this domain name from a commandline.

RE: Images invisible

[Carl . Scarlett]

Good lord Greg.  Silverlight seems determined to drive you screaming for
the hills.

 

I sympathise completely, but can offer no help.

 

Good luck!

 

Carl.

Subject: Images invisible

 

Late last night I was working away on my SL3 app doing the compile-run,
compile-run thing over and over as usual. Without warning the app fired
up and all of the images were blank. And by "blank" I mean invisible.
All 61 images in the solution seems to be taking space on the screens,
but are invisible/blank. There are no loading errors or JavaScript
errors or any warnings of any kind.

 

I deleted all binaries and rebuilt everything. I've rebooted this
morning and rebuilt everything. I tried to use Fiddler2 to see if there
were any silent 404s, but it won't trace localhost (there are dozens of
pages of instructions on how to do this, but they all are nonsensical or
don't explain where the settings are in Fiddler2 to allow this).

 

I have never seen anything like this in my life, and I never would have
guessed such a thing was possible. I would have been less surprised if
my machine sang the national anthem when I ran the app.

 

I've already wasted 2 hours on this, so I thought I'd mention it anyway
just in case someone has seen the symptom before.

If you change the localhost URL to "somesite.com" (it resolves to
127.0.0.1) then you can use fiddler to see what's going on. Also try
silverlight spy?

Images invisible (addendum)

[Greg Keogh]

The invisible images problem only happens on my dev machine.

 

I copied the whole solution to my live web server and loaded it in IE8 via
IIS and it looks normal. Is it something to do with running it under the
Visual Studio Development Server on port 55310? That's the way I've been
running it for the last 18 months.

Dynamic creation of Accordion items crash (solved)

[Greg Keogh]

It was an intellisense induced error. The second TextBox should have been a
TextBlock. I was applying a style intended for the wrong type, bu tcouldnt
see it for looking. Great error message eh!? --Greg

 

Dynamic creation of Accordion items crash

[Greg Keogh]

The following code crashes on the highlighted line with catastrophic failure
0x8000. All I'm doing is looping to create items for an Accordion
control. It's just dying when I assign the (non null) Style to the second
Textbox. Anyone tried this sort of thing before?  - Greg

Liquid Rich Text control

[Stephen Price]

Quick one,

Has anyone used the Liquid Rich Text box? It doesn't seem to be "real" rtf
format and we need a way to convert it's output into rtf for Active
Reports.

thanks,
Stephen
