Dear Abhinav,
Thanks for your time in replying to my question.
You mentioned that eventhough my application after converted to xbap application it wont work for images.
But my question is, am going to host the database server and the IIS server in the same machine. In that case it should work fine right?
my windows application is working fine for this case.. when my application and the database server in the same machine its working fine.
But i have one doubt. I read in the google that when ever user clicks the xbap , it will internally handles the exe downloads and all.
Which means that everytime the user clicks the link will it downlaod the exe application? and will it run from local machine?
can you please help me to get clarified on this?
that is the case once again its going to be a windows application and will have same image problem?

Hi,
I have few input controls in my ClaimsReport.xaml, based on the user input i have to hit the database fetch records and display those records in UI with header & footer. Along with I have to provide print option to generate the report with header and footer & export to Excel, .csv, .txt formats. Please suggest or share me how to achieve it. Refer the below screenshots.

Please explain more clearly what your problem is; I don't think anyone is going to write this code for you.
One of these days I'm going to think of a really clever signature.

As Silverlight does not have a decent reporting interface we use SSRS to create an embedded (local RDLC report) this is generated in the WCF on the server where there are no restrictions on data. The report is passed to the SSRS on the server and exported to a PDF file.
This PDF is then passed back to the client as a binary file and displayed via Telerik PDF viewer.
I'm not sure whether this is a valid solution for you but it has a number of benefits:
SSRS is excellent for building and maintaining reports
The same report can be used in SSRS server
I don't need a dedicated SSRS Viewer (approx $500) I can used any Silverlight PDF viewer
I don't need to deal with the export issues, Telerik does all that out of the box.

Are you saying that your chart component is a WinForms component which you are trying to use in a WPF application? If so, you don't need to worry about DPs (the shorthand name for Dependency Properties). The big question I have to ask here, is have you added the control into a WindowsFormsHost container? An example would look like this
<Grid>
<WindowsFormsHost>
<myNamespace:MyChartControl />
</WindowsFormsHost>
</Grid>Then, you just add your configuration as you see fit.

Hi Pete.
No, I have modified the chart so that it can be used in WPF applications without WinFormsHost. It's a WPF component without DP's.  The chart object itself is derived from ContentControl but it's properties and their sub-properties are normal classes - not derived from Dependency Object.

What does the rest of the exception say?
|
|
|
|
|
That is all it says. It's a small message box that says "An exception has been thrown" or something like that and it has a "Details" button which shows "Exception of type 'MS.Internal.Validate+ValidationFailure' was thrown.".

Have a look in EventViewer. I suspect you'll find a fuller message there.

Nothing there.

Unfortunately, there's not enough context there to figure it out I'm afraid. Do you have VS SP1 installed?
|

It could well be. Is there a reason that you can't use your WinForms version? As you know that's stable, you could be getting by with that while you sort out the chart.
On a different note, you can achieve a lot of what you want to do if you embrace MVVM architecture and use that as the underlying mechanism for getting data into your charts. It's a lot simpler model to get your head around than DPs so it could save you a lot of grief.

To be exact, there are two versions of the chart: WinForms (VS2008) and WPF (VS2010). WPF version uses the same classes as the WinForms version but I use conditional compiling to make the necessary modifications to source code.
The WPF version works well if you configure it in code-behind but my boss wants the WPF version to work in WPF/XAML designer as well so what can I do. Many our customers want the WPF version (the younger generation of software developers) so there's not much I can say. Since there's the air-space problem when using WinFormHost it's out of the question.
MVVM is a good option but I cannot use it right now. It would take a pretty long time to convert the current source code to match MVVM ideology. Perhaps in the future chart versions MVVM will be implemented one step at a time...

I changed the view property and the X axis list to dependency properties but no luck. Then I created a new class (XAxes) that implements IList<axisx> and IList (and replaced the List<axisx> property in the view class with that) so I could debug if accessing the X axis list doesn't work. Didn't see anything wrong with that. But when I add two X axes in addition to the already created X axis this exception pops out in designer: http://postimage.org/image/8an21q0jr/[^]

Something pretty weird is going on when inserting elements to the list. Well, I'm out of ideas. I'm probably going to have to tell people not to use XAML code or designer in WPF until this problem is solved. Put "[Browsable(false)]" on every property or something...

I have two listbox binded with the same collection. I want to have different content in both the listbox using the same collection by doing filtering.
How can i achieve my target using wpf and mvvm?

Take a copy of the collection so you have 2 distinct collections to bind to!

Hi all,
I have a WPF application that needs to be universal across XP, Vista, Win 7 and Win 8. I have it working on all apart from XP, the reason it doesn't work is I get an error message
The image decoder cannot decode the image. The image might be corrupted
The error is being caused by the image I have the MainWindows Icon property. The image is a .ico file which resides in my resources.
I would suspect that the image is corrupted except when I run it on all other OS's I have no problems. Has anyone ever come across any problems with XP struggling to accept a .ico image? and if so how do you suggest I go about this?
Thanks!

Can you open your icon with some other program on XP? If not, you'll have to change it so that it can be opened there (it's best to create it on an XP machine).
|
|
|
|
|
It is a .ico file - I think these are incompatible with Windows XP but that's just a guess. I'm just going to create a separate library of images with a different file type and see what the outcome is.

I've been trying to code my first MVVM app, and I'm not sure I've got things right! I'm using
Packt Pub's WPF Cookbook 4.5 [^] as a main ref.
I have a 3 main objects, Suite, which contain 1 or more Jobs, which contain 1 or more Dependancies, and finally there's a 4th Suite Collection.
At the moment each of these are inheriting from ObservableObject (that basically just helps if INPC). And Suite contains an ObservableCollection<<Job>>, Jobs an ObservableCollection<<Dependancy>>.
Is this right? Should the model contain the INPC stuff?
My ViewModels inherits from ViewModelBase, which also inherits ObservableObject. ViewModelBase takes a generic Model parameter. Which when creating the ViewModel is set to one of the model classes above.
In the ViewModel I've got properties like this that wrap the underlying model's property:
public string Suite
{
get { return Model.Name; }
set { Model.Name = value; }
}
But I've implemented the collections as:
public IEnumerable<JobVM> Jobs
{
get { return Model.Jobs.Select(f => new JobVM(f, this) { Model = f }); }
}
I understand why the conversion to a VM is needed, but I'm not quite sure how it works when I want to add Jobs, but it seems too.
So I've been building things up, but adding/removing and editing items in the collections doesn't seem to be as smooth/easy as it should be, so I'm questioning if I've got the bottom bits right before I keep hacking away!?!
If what I've got is about right, then I'll have some more q's!

Everything that you bind to needs to implement INPC / INCC at some level.
So ObservableCollection<x> already implements INCC for you, but x needs to implement INPC. If you have a nested ObservableCollection<y>, that ObservableCollection will handle the INCC notifications for that collection, but y needs to implement INPC and so on.
