Hi Expert,
i'm doing some program for my project which using WPF, to create
my application more managible i would apply "user control" concept for
my project for each section of my workspace.
to make my workspace more flexible, all the "namespace" and "user
control" name will store into DB, once user launch my application,
base on different user setting i'm able to load for different user
control accordingly base on on the DB record.
i have 2 question now:
1. How to declare those user control "name space" thru codebehind ?
right now i only able to code my "name space" at XAML
example: xmlns:uccustom= "clr-namespace:WpfAp plication1"
2. How to declare the "user control" name thru codebehind?
right now i also have to declare the user control name at XAML
example: <uccustom:UserC ontrol1 Margin="20,0,-605,-236.5"
Height="188" VerticalAlignme nt="Bottom"/>
* so far i only know to do the setting from XAML, but which is not
enough flexible due to setting concept.please advise , thanks

If you can't automatically generate the XAML to layout your UI
conditionally as you like, you can just write C# code to do it. I presume
that's why you're posting here in the C# newsgroup.
Beyond that though, it's not clear what you're asking. You can design
your own UserControl sub-class, and then in the code that goes with your
XAML, just check the database record you care about and conditionally
add/place whatever UserControl instances are appropriate to that database
record (after instantiating them explicitly, of course).
I don't know that there's really any specific answer to your #2 question;
it seems to me that you'd just use XAML to define each UserControl
sub-class as appropriate, as you're already doing. For the #1 question, I
don't understand why the default name space isn't appropriate, nor why you
care, given the rest of what you wrote. But assuming it's important, it
seems like you could just explicitly write a new namespace as appropriate
for your needs (you have to change it in both the .xaml and the .cs file).

Hi Pete,
thanks for your reply, yes, i use C# to develop my
application.
try to imagine, i develop a dockPanel inside my WPF windows ,
which is open for my colleage to post their own "user control" , for
sure my colleage have to develop their own XAML file ( and code
behind) and make as dll , once they done for their User control, they
will goto database to provide the user control name space and user
control name, base on the login , my dock Panel windows will trigger
"their" own user control from my dock panel.
i have no experience to write the code behind to execute and
build the "user control" at runtime.
best regards

You mention "code-behind", so I'm assuming you're doing some sort of web
application. Hopefully my comments aren't too far off track; they're
based on my experiences with regular non-web applications, but hopefully
the same principles apply.
You really have two parts to your goal: 1) dynamically adding UserControl
sub-classes to your existing WPF window, and 2) providing "plug-in"
support for said sub-classes.
The #1 part is easy enough. You simply instantiate your UserControl
sub-class and add it programmaticall y.
The #2 is more complicated. Creating the DLL with the UserControl
sub-class isn't difficult, but then you need to use reflection to load the
DLL (assembly), and you need to write some code to map the names found in
the database to those found in whatever DLL's have been loaded, and of
course after all that, you need to use reflection to do the instantiation
of the UserControl sub-class as required for part #1. See the
System.Reflecti on namespace for more details.
Whether any of this addresses the two specific questions you asked, I'm
not sure. But it seems like it's the information you actually need given
the stated goal. :)

Hi,
I am writing an mp3 player using wpf, I have three user controls (media
library, media controls and a playlist). Obviously I need these to
interact with each other, I assume the best way to do this is to use
events right ?.
Can I raise an event on one user control and have one of the others
suscribe to it ? or do I need to have the main window suscribe to it and
then pass the message on to the target user control ?.

Hi Moondaddy,
I downloaded your sample project and run it on my machine. I did see the
problem on my side. The image drawn in the Button is not as clear as that
one drawn in the Image control.
After doing some research, I found that this is a WPF layout problem.
When we place a control into a parent control, if the child control's Width
and Height properties are not set, the child control will be streched to

Hello All--
Just a general (or perhaps loaded) question - is it considered good or bad
practice to use code-behind with a CustomControl.generic.xaml file?
For instance, with a control I'm creating, it would be nice to use a
DispatchTimer to "ramp up" a value, depending on how long the mouse is held
down.
Thanks,
