Cannot add content to object of type 'System.Windows.Navigation.NavigationWindow'

Posted By:      Posted Date: September 16, 2010    Points: 0   Category :WPF
 
Hello, i'm trying to add content to a custom class inherited from System.Windows.Navigation.NavigationWindow but i receive the following error: Cannot add content to object of type 'System.Windows.Navigation.NavigationWindow' This is the XAML of my Window: <NavigationWindow x:Class="Obolus.Windows.MainWindow"     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"     Title="..."     Style="{StaticResource MainWindowStyle}" ContentRendered="NavigationWindow_ContentRendered" >     <Grid></Grid>     </NavigationWindow> what i want is drawing shapes in this window, which will act as container and background for a lot of pages inside. It will be a classic Wizard. In .Net Windows Forms i override the OnPaint method of any control, and i draw all the things programatically. I don't know hot to do it in WPF. ¿Adding shape contents to the window? ¿overriding OnContentRendered? ¿any idea? Thanks in advance, Best regards, Raúl Truco,

A first chance exception of type 'System.ArgumentException' occurred in System.Windows.Forms.dll

  
I've read a bit about this error and maybe I have nothing to worry about.  BUT ... my simple little app gets 7 of these before it even gets to the first Dim statement in the Class Form1!  I found and followed instructions on how to have the Debugger intercept these exceptions but it seems that they are not being intercepted.  I only know that they have happened because of the messages in the Immediate Window.  In the Designer all I have is 5 Labels and 5 TextBoxes.   Any thoughts on how I could get to the cause of these messages? Thanks,  Bob

Converting a System.Windows.Control.Image object to byte array.

  
Hi i need to convert a specific System.Windows.Control.Image object into an (int) array, because i'm trying to convert a silverlight application into a wpf project. private void createGi02GradBrush()<br/> {<br/> WriteableBitmap oWriteableBitmap = new WriteableBitmap(256, 256);<br/> Image oImage = new Image();<br/> oImage.Arrange(new Rect(0, 0, 256, 256));<br/> oImage.Measure(new Size(256, 256));<br/> oImage.Source = new WriteableBitmap(256, 256);<br/> Gi02GradShaderEffect oGi02GradShaderEffect = new Gi02GradShaderEffect();<br/> oGi02GradShaderEffect.pArray = oPImageBrush;<br/> oGi02GradShaderEffect.gi1GradArray = oGi1GradImageBrush;<br/> oImage.Effect = oGi02GradShaderEffect;<br/> oWriteableBitmap.Render(oImage, null);//here<br/> oWriteableBitmap.Invalidate(); <br/> this.oGi02GradImageBrush = new ImageBrush();<br/> this.oGi02GradImageBrush.ImageSource = oWriteableBitmap;<br/> } I've found some similar topics however Image object is not the same and most of its methods aren't available. Here I'm rendering a writablebitmap with a given Image object, but in wpf we need an array. oWriteableBitmap.Render(oImage, null); Any idea? Thanks. Joseph.

I built Objectdatasource through dataset. When I built update page using dataset. It generate the following error before showing the update page correctly.

No mapping exists from object type System.Xml.Linq.XDocument to a known managed provider native type

  

Hello,

I am using XML in getting client data in 3-tier architecture, using XDocument in passing XML among layers.

But when I use it in inserting this XML in XDocument, it throws the following error:

No mapping exists from object type System.Xml.Linq.XDocument to a known managed provider native type. 

I am using the following code, it throws the exception at the bold line:

Assigning External content type field column value using Client Object Model

  

I have a problem assinging External column value to ListItem object with client object model-based application I'm developing. To be precise, I am able to retrieve data related to external content type by reading external list created from this content type but I don't know how to properly use it to assign value to this field. By doing some research on my own I concluded that BDC ID column from external list is the way to go since it uniquely defines selected row from external list but that doesn't tell me much since I don't know what to do with it. Currently I ended up with partial solution - to assign plain string value of picker column but that makes this value visible only in "View Properties" option on Sharepoint and not in "Edit Properties" which pritty much makes sence since it isn't properly related to rest of the data in specific row. Does someone have a better solution for this?

Using IPC only channel getting Unable to cast object of type 'System.Runtime.Remoting.Identity' to

  

I have a remoting application that is using delegates to preform callbacks between processes. I found that if I don't use a TCP channel at all and only initialize an IPC channel that the callback delegates start throwing the following error after about a minute has passed.

From what little I could find on Google it seems to be a Lifetime Service management issue but all the classes that the delegates belong to return null from InitializeLifetimeService which should give the object an infinite lifetime.

With the TCP channel initialized the issue doesn't happen, but I would like it to use the IPC channel if all of the processes are on the local box.

Error: The type 'System.Windows.DependencyObject' is defined in an assembly that is not referenced

  

Hi

I have an ObservableCollection which I would like to sort.

List
<TLstNodeData> SWNodeList = TopNode.SubNodes.OrderBy(SNode => SNode.NodeDispText).ToList();

In a WindowsForm application targeting the .NET 4.0 Framework it compiles and works as expected.

If I do this in a WCF Service in my web project also targeting the .NET 4.0 Framework I get the following error.

Error 1 The type 'System.Windows.DependencyObject' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Windows, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e'.
