Hmm. I took a quick look. The 'CAB' appears to be fairly complicated, and may be overkill for what I'm doing. Also, the mix of WinForms and WPF is a little off-putting. I thought that WinForms has been 'deprecated' now that WPF is available?
My application is actually a touch-screen control panel for some machinery. The 'tree control' in my example may actually be a picture of the machine. When you click on parts of the picture, you see detail information related to that component.
I'm not too worried about the architecture of the application. I was mostly interested in the mechanism I was using for changing the content of the detail view. It seemed like there were several ways to accomplish what I was after, and I wasn't sure if there were any I should avoid.
For example, instead of using a Frame as a container and Pages for the contents, I could use a Grid and set the appropriate Grid entry to a UserControl. Each detail view would then be implemented as a UserControl.
Thanks for the info; I'll keep it in mind.

Gary - you don't have to use the WinForms parts, however, if this architecture is too much you might want to consider using MVVM. The idea of using UserControls is a good one, and is a good basis for doing this. Obviously, you would want to bind to the selected item on the treeview to decide which usercontrol to load.

That's pretty much the outline I had in mind. We've developed this sort of application before using an MVC pattern. MVVM sounds like MVC with some of the serial numbers ground off  . Thanks for the feedback, Pete.

Shh. You're not supposed to notice that.

I wouldn't use a frame for this. Have a look at ContentControl it can be a 'host' in a Grid for the user controls you create for the right hand panel.

i have created a user control Dynamically and added it to a Wrap Panel as a child. now if i remove it from panel but it still remains in memory.
i want it to be permanently removed from memory. There is no Dispose method available. and i also tried by implementing idisposable interface and overwriting the Dispose() method for my control but it still remain in memory.
Is there any way to remove this object(User Control) from memory
Regards
Rishi

Nope. WPF uses MIL handles internally, and the garbage collector is called as and when it is needed. When you think about it, this makes perfect sense - the whole point of WPF is that it doesn't need you to access unmanaged resources to do things (you can, but you aren't required to) so you don't actually need to Dispose controls.

Thanks Pete for reply
but in my case i need to remove this user control from memory . becoz after removing it from canvas or panel , if i try to fire some event then this Control also respond the event (Though it has been removed).
for a workaround i detached the Event Handler for user control(when i remove it from canvas/panel). but it still resides in memory and remains throughout the program execution (becoz this control is not local to any Block) thus degrading performance .
Regards Rishi.

Unfortunately you can't automatically remove the control deterministically. You could, possibly, remove the control by forcing a garbage collection, but this really is a bad idea.

Dude, calm down. You should pity these fools for being both stupid enough to need this type of help to start with and being desperate enough to spam all sorts of forums to find it.

I created that plan like all great plans. I outsourced it, some guy named Nagraj Naik came up with that one.

WPF Unleashed - Adam Nathan is a really good book I read.
|
|
|
|
|
As well as the Nathan book, you must get this one: Pro WPF[^]
|

That is definitely a good suggestion, I would suggest any of the WPF books from Apress.
