Based on your description, and WYSIWYG, I would just capture the Window's client area as an image.
Lots of C# code around to do that.

That's what my code already does, the problem is that the WinForms portion doesn't render as part of the WPF rendering process, so I'm calling a method on the WinForms control to return it's visible area as a bitmap, then replacing it ove the Winforms control.
I was hopeing there weas some way of forcing the WinForms control to render in the WPF rendering when the entire view is rendered.
If it's not broken, fix it until it is

There's a (free) WPF chart control; why do you need to use the "Windows Forms" control? (I didn't think that control was that special).

I have a UI with a MainWindow, which has a tab control. Some of those tabs have child tabs. So for Main Tab 1 there are 3 Child Tabs.
When the user selects Main Tab 1, Child Tab B, then clicks File->Print on the menu, how would you pass that menu command to the Active tab? Or somehow notify the ACTIVE TAB to print?
Thanks
If it's not broken, fix it until it is

Bind the TabControl.SelectedIndex
<telerik:RadTabControl Grid.Column="2" SelectedIndex="{Binding SelectedTab,Mode=TwoWay}">
Telerik has that property not sure if the standard TC does.

Did you even read the question?
What does binding the tab's SelectedIndex have to do with the Menu's Print command getting paassed all the way down the visual tree??

I assumed you are doing the printing from the VM, forgot you have your odd printing method.
Still I would do it the same anyway, tab changed is bound to the VM and sets the active tab, Print command tells a VM property for each tab to print. Seems like a complete kludge but then you have a creative printing method!

If the TabControls are implemented as a List of Lists of TabControls (or similar) in your AppComposer file (or App.xaml.cs, wherever you defined them), you could just go through said list(s) and look for the TabControl.SelectedTab property.
Once you get hold of the active/selected tab that way, you could notify it to print.
Edit:
Just noticed that's about the same as what Mycroft suggested...but I would go for it as a first approach anyway

Does anyone know how to change the Spell Checking language of a WPF TextBox control to UK English.
I have tried setting Language="en-GB' and xml:lang="en-GB" as advised on all the websites - it does not work!
The software I am writing is literacy software (XAML Front end, C# Code Behind) for an education centre and needs to spell check in UK english
It seems really strange that WPF does not support UK English
- Windows does??
I have done this in a previous version of the software, but I think I implemented it as WinForms and maybe used a Word Interop for spell checking - but I cannot be sure that the users will have Word installed . . .
Please, Please, Help!
I read somewhere I can add a custom dictionary for UK English
anyone know where I can get one in .lex format
I have a file with all the differences between UK and US English - can I use this somehow
|
|
|
|
|
|
Hmm . . . thanks Muhammad, I tried that, it did not work for me, thanks for your answer
OK, I finally figured it out
I can set the default language once for the whole application using:
<i>// Set default language to UK English . . .</i>
Thread.CurrentThread.CurrentCulture = System.Globalization.CultureInfo.GetCultureInfo("en-GB");
FrameworkElement.LanguageProperty.OverrideMetadata(typeof(FrameworkElement),
new FrameworkPropertyMetadata(XmlLanguage.GetLanguage(Thread.CurrentThread.CurrentCulture.Name)));
After that, all TextBoxes and RichTextBoxes use UK English for SpellChecking
Many Thanks for all your help

I am trying to put a WPF Control in a winform for a project at work. I have done before for small controls and it worked well. I even put the DiagramDesignerPart1 in a winform as a practice run and did ok but some of the resources were missing and I did not notice or did not think it was a big deal.
Now I am trying to put the DiagramDesignerPart4 in a winform panel and the resources are missing at runtime.
The control shows all the resources at design time but when I run they are missing.
Also if I set the project to startup project that window runs fine and the resources all show up.
I have searched and searched for the answer and have not been able to get anything to work for me.
I did the following
1) I added the project to my project
2) Created a WPF Control and called it DiagramEditor and copied the xaml code into that to change it from a application to a control
3) I created a themes/generic.xaml file to put the info that was in app.xaml there
First I had a problem with the program crashing runtime using the static resources and the error was that it could not find the resources.
Then I changed to DynamicResources and it runs but none of the resources are showing up.

Thanks, I read in one of the many pages I looked at that we should have a generic file and the folder is created when we create a new custom control. I never saw this question in my list so I did not think it had posted, but I got the problem resolved by putting the resource links in The control resources and the window resources in those xmal files. I also had to change most of the static resources to dynamic resources. So far I just put the page on a panel in my winform app and did a little testing but the major revamp will come next week as I add stuff to it .

Great link.
The first time I've seen someone admit that MVVM does NOT mean you NEVER have code behind.
He articulated what I always thought of as "display logic"; that every MVVM "fan" twists themselves into knots over trying to avoid.

Hi All,
I am using the following View and View Model in VB.Net, when I am trying to reference the View Model as DataContext
View is like this below

Try taking the space out from between "clr-namespace:" and the namespace:
xmlns:empns="clr-namespace:TestWPFVBApplication.ViewModel.EmployeeViewModel"

We are getting this error on a WPF to WCF application, mostly when the user wants to upload a file, the files are generally fairly small 200-300kb. It happens mostly for a WAN connection but has happened locally as well.
I have synched the web config and the client values. They are all maxed to int.MaxValue. We have even resorted to setting the MaxItemsInObjectGraph for each method on the client and we still get the error intermittently.
I enclose the code for getting the service client. Any suggestions will be appreciated and followed up assiduously.
static NPAFinSvcClient GetNPAFinServiceClient()
{
string url = string.Empty;
~#if DEBUG
url = "http://localhost:49223/NPAFinSvc.svc";
~endif
NPAFinSvcClient client = new NPAFinSvcClient(GetBinding(), new EndpointAddress(new Uri(url, UriKind.RelativeOrAbsolute)));
foreach (OperationDescription op in client.ChannelFactory.Endpoint.Contract.Operations) {
DataContractSerializerOperationBehavior dataContractBehavior = op.Behaviors.Find<DataContractSerializerOperationBehavior>() as DataContractSerializerOperationBehavior;
if (dataContractBehavior != null)
{
dataContractBehavior.MaxItemsInObjectGraph = int.MaxValue;
}
}
client.Open();
return client;
}
static BasicHttpBinding GetBinding()
{
~if Release
var binding = new BasicHttpBinding(BasicHttpSecurityMode.Transport);
~else
var binding = new BasicHttpBinding(BasicHttpSecurityMode.None);
~endif
binding.MaxReceivedMessageSize = int.MaxValue;
binding.MaxBufferSize = int.MaxValue;
binding.SendTimeout = new TimeSpan(2, 0, 0);
binding.ReceiveTimeout = new TimeSpan(2, 0, 0);
binding.ReaderQuotas.MaxArrayLength = int.MaxValue;
binding.ReaderQuotas.MaxBytesPerRead = int.MaxValue;
binding.ReaderQuotas.MaxDepth = int.MaxValue;
binding.ReaderQuotas.MaxNameTableCharCount = int.MaxValue;
binding.ReaderQuotas.MaxStringContentLength = int.MaxValue;
return binding;
}
