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.

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

I tried no use, nothing changed.
Here is that, but still it says the EmployeeViewModel is not in that namespace. Anyhelp please?
xmlns:empns="clr-namespace:TestWPFVBApplication.ViewModel"
And Error is:
EThe name "EmployeeViewModel" does not exist in the namespace "clr-namespace:TestWPFVBApplication.ViewModel".

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;
}

You missed
maxBufferPoolSize
(Defaults to .5 mb?)

Thank you I will see if that relieves the problem

I would like to bind a nested property of an attached Property
public class MyTag
{
public decimal MyValue { get; set; }
public string MyDescription { get; set; }
public bool Enabled { get; set; }
}
Build the attached property.....
public class Attached : DependencyObject
{
public static readonly DependencyProperty MyTagProperty =
DependencyProperty.RegisterAttached("MyTag", typeof(MyTag), typeof(Attached),
new FrameworkPropertyMetadata(null,
FrameworkPropertyMetadataOptions.BindsTwoWayByDefault | FrameworkPropertyMetadataOptions.Inherits));
public static MyTag GetMyTag(DependencyObject dObj)
{
return dObj.GetValue(MyTagProperty) as MyTag;
}
public static void SetPLCTag(DependencyObject dObj, MyTag value)
{
dObj.SetValue(MyTagProperty, value);
}
}
and would like to bind in xaml like this
<Button
x:Name="button"
Width="75"
general:Attached.MyTag="{Binding First}" // First is an object of type MyTag
Content="{Binding Path=(general:Attached.MyTag.MyValue)}"/>

I've written a "typical" WPF application that utilizes data binding and displays a number of "slides". To view these slides, the user selects one from a ListBox.
One of the requirements is to save the selected slide as both a JPG and Power Point slide. This works great.
The other method for saving the slides allows the user to save all of the slides with the click of a single button (without selecting one first). The idea is to create the slide in memory, and save it. The problem is that any bound elements on the slide do not get included in the saved image.
This is the code I use to "render" the card in memory:
CtrlMySlide slide = new CtrlMySlide();
slide.Visibility = System.Windows.Visibility.Visible;
Dispatcher.Invoke(new Action(() =>
{
slide.RenderCard(this.FiscalPeriod, item, true);
slide.Measure(new Size(1024d,768d));
slide.Arrange(new Rect(0,0,1024,768));
slide.UpdateLayout();
}), DispatcherPriority.ApplicationIdle, null);
slide.Save(result, true);
EDIT ===================
I also tried creating a modal window and rendering the slides to that window. Same result.

Well, I don't know why this works (yet), but this was the answer.
0) Create a modal window.
1) Add a delegate for the Render method to the window
2) Add a method to call in the window, like this:
public void SetSlide(UserControl slide,
RenderDelegate renderMethod,
DateTime fiscalDate,
VMSlideItem slideItem)
{
this.gridMain.Children.Clear();
this.gridMain.Children.Add(slide);
renderMethod(fiscalDate, slideItem);
slide.Measure(new Size(1024d,768d));
slide.Arrange(new Rect(0,0,1024,768));
slide.UpdateLayout();
}
The key was calling the slide's render method from within the window (and yes, I still had to call Measure, Arrange and UpdateLayout).

I have a simple UserControl that has one dependency property:
public partial class MyUserControl : UserControl
{
public MyUserControl()
{
InitializeComponent();
}
public double LocationX
{
get { return (double)GetValue(LocationXProperty); }
set { SetValue(LocationXProperty, value); }
}
public static readonly DependencyProperty LocationXProperty =
DependencyProperty.Register("LocationX", typeof(double), typeof(MyUserControl), new PropertyMetadata(0d));
}
The user control just has a single rectangle in it, and I want to bind it to the ItemsControl:
<ItemsControl x:Name="myCanvas">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<Canvas/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemContainerStyle>
<Style>
<Setter Property="Canvas.Left" Value="{Binding LocationX}"/>
<Setter Property="Canvas.Bottom" Value="0"/>
</Style>
</ItemsControl.ItemContainerStyle>
</ItemsControl>
Its binded to an ObservableCollection:
public partial class MainWindow : Window
{
ObservableCollection<MyUserControl> myData = new ObservableCollection<MyUserControl>();
public MainWindow()
{
InitializeComponent();
myData.Add(new MyUserControl() { LocationX = 50 });
myData.Add(new MyUserControl() { LocationX = 350 });
myCanvas.ItemsSource = myData;
}
}
The Canvas.Bottom is set according to the value given, but the value I want to be binded won't work correctly. What Am I doing wrong here?
|
|
|
|
|
Damn, answering my own question, again:
Well, all I need to do is to set the x:Name="MyControl" in the user control, and in the binding set ElementName=MyControl, Path="LocationX"
|
|
|
|
|
A much better approach would be,
<... Value="{Binding Path=LocationX, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}}"/>

Yeah, I did try that too, and it worked fine for my other controls when the Dependency Property was within the Control that I wanted to bind to. Btw, you don't need the x:Type to make it work:
Text="{Binding RelativeSource={RelativeSource AncestorType=UserControl}, Path=XLabel}"
But as soon as I had a collection of different user controls and I wanted to access them, I had to say ElementName for some reason. I guess it was because it couldn't find the correct property in the first Ancestor type.
|
|
|
|
|
Why would this be a better approach?

You might set the name of the user control to something different when its an element in your window. Setting the name property in the user control will still work though since it is initialized before the containing window. Using Binding.RelativeSource is a suitable option.

I ended up by setting the x:Name and specify the ElementName as I said, but I would really like to know how to implement the RealativSource in my project.

I couldn't see exactly how to do it.
