problem parse xaml and blank spaces

Posted By:      Posted Date: October 05, 2010    Points: 0   Category :WPF
 

Hi, I have a problem parsing an xaml with characters 
 and space blanks, the space that show me is different that show in Silverlight.

this is the code to parse the xaml

            xml_node = nodo.OuterXml;
            text = (System.Windows.Controls.TextBlock)XamlReader.Parse(xml_node);

            if (text.Height != double.NaN)
              text.Height = double.NaN;

            text.Text = text.Text.Replace(' ', (char)160);

            if (text.Visibility != Visibility.Collapsed)
              res.Children.Add(text);

And this is the code of xaml:

  <TextBlock x:Name="Elemento_300920102232365" Canvas.Left="121.488" Canvas.Top="125.682" Width="1705.799" Height="2169.455" Text="&#xD;&#xD;&#xD;Jamón de Bellota (reserva) / Pernil de Bellota (reserva)                         17'00 €&#xD;Anchoas del Cantábrico / Anchoves del Cantàbric  &

Allow blank spaces in textbox

  
Hi,   I have a simple issue..the user types his/her name in a textbox. Accidentally if a space is entered after a name or before, is it possible for me to trim it while accepting and not raise any error (which actually arises when the textbox is empty)? Actually, not raising an error is the issue!    Thanks!

problem with XamlReader Load/Parse image

  

I got error with this below:

string imageCompXaml = serialized image (bitmap)

Image imgObj = XamlReader.Parse(imageCompXaml) as Image

err: Property 'UriSource' or property 'StreamSource' must be set

i can workaround the problem by

  imgObj = new Image();
  imgObj.BeginInit();
  imgObj.Source = BitmapImageObject;
  imgObj.EndInit();

problem is by doing i missed out lot of other details.

I have a string, this is the serialized of the Image object, which is BitmapImage

I missed out the Image.prop details, like the width/height.

the image size is not same as the BitmapImage object, its a scaled/sized-down bitmap.

so using the 2nd Source workaround, i can't get back the actual image sizing (b4 serialize)

is there a way i can tackle at the XamlReader.Load/Parse() to resolve the err

or how to get back the image prop/details with my workaround?

XAML Serialization Problem

  

I try to save (serialize) a XAML document. The background is that the user of the application should be able to change the XAML document dynamically.

This works fine with some basic controls but as soon as I have a datagrid inside the XAML, non of this works:

System.Windows.Markup.XamlWriter.Save throws:

Cannot serialize a generic type 'System.Collections.ObjectModel.ObservableCollection`1[Microsoft.Windows.Controls.DataGridColumn]'.

System.Xaml.XamlServices.Save throws:

Constructor on type 'System.ComponentModel.ComponentConverter' not found.

I already found in forum that XAML does not fully support generics, however, is there a solution for this? I'm a bit confused because if XAML can be read dynamically it should also be possible to save it...

I use .NET Framework 4.

Thanks for reply... any suggestion is very welcome.


Attached Event Registering Problem in XAML vs. CS

  

Hi,

I spent hours searching for a solution to this, but did not find a proper one.

As stated in this post here, there seems to be a difference in how attached events are registered in XAML and in C#.

As described in the MSDN documentation , WPF requires you to implement two methods (AddXYZHandler, RemoveXYZHandler) in order to use an attached Event (XYZEvent) in XAML:

 

public static readonly RoutedEvent XYZEvent = EventManager.RegisterRoutedEvent("XYZ", RoutingStrategy.Bubble, typeof(RoutedEventHandler), typeof(XYZClass));

public static void AddXYZHandler(DependencyObject d, RoutedEventHandler handler)
{
 //event registration comes here
}

public static void RemoveXY

Problem streaming xaml file

  

So I am trying to stream the file "test.xaml" (on the root of my project) to a canvas. I have tried numerous methods and for some reason when I call it to stream the xaml document but it doesn't.

My Code:

System.IO.Stream s = this.GetType().Assembly.GetManifestResourceStream("test.xaml");
StreamReader sr1 = new StreamReader(s); 
string xamlString = sr1.ReadToEnd(); 
debug1.Text=xamlString;

canvas1 = XamlReader.Load(new System.IO.StreamReader(s).ReadToEnd().ToString()) as Canvas;

 

To debug, I made a textblock element called debug1 and I wanted to send my code stream as a string to the textblock (to see where my problem is).

Whats interesting is that after line 2 no code will be executed; I know this because the debug1 textblock isnt populated with any data (it remains with its default "textblock" text value). I do not get any errors back or anything.

I know how to put prewritten xaml on a canvas in a ton of ways. I just want to know why xaml file is not streaming at all (is the code right?) (is there something im forgetting?) (is there a better way of going about this?)

Quicknote: My xaml file is just a page xaml document, there's nothing special about it format wise. Also I have been searching a day now and I haven't found anyone with the same issue.


Approval Workflow blank status problem.

  

We noticed an issue in our environments where under certain conditions an approval workflow has a blank status.

I have since been able to replicate this in a vanilla environment, and have tried up to the June 2010 CU. I will be trying on Oct 2010 CU soon.

Steps to reproduce...

1. Create a document library
2. In versioning set Require Check Out to Yes.
2. Create at least one document in the newly created document library and check in.
3. Create an Approval Workflow by using a workflow template (go to Settings -> Document Library Settings -> Workflow settings and then set up an approval workflow). Ensure that this workflow is configured to started when items are modified, and is used for content approval (after workflow is completed, update the approval status).
4. Modify one of the documents contained within the newly created document library. The workflow starts automatically.
5. On the newly created document library page, you will notice that the <workflow name> column is displayed but it does NOT show the status of the workflow.

If you look at the workflow on the item it will show up as "in progress" but on the library is is blank.

So far it looks like this only occurs when required check out is turned on.

Any ideas anyone? Are we missing something?

Thanks!

Phil.

Thats why i tried to group the radio buttons in vertical manner. Let i have a requirement like below:
