Did you read the blog post I linked to? It has links to Microsoft's instructions for setting up MIME types in IIS.

Instructions for setting up MIME types in IIS6:

Configure MIME Types (IIS 6.0)[^]

Instructions for setting up MIME types in IIS7 (or later):

Re: Application download error in XBAP application after deploying the application

20-Sep-16 10:02

Hi,

I installed all those Mime types on my Server, still I am getting the same error, can you please give me some suggestion about it?

I have copied .exe file, .manifest file and .xbap file from bin directory of the application into Virtual Directory, am I missing anything here? Do I need to have .deploy file etc?

I followed all the steps that are provided here : GADS Open Source[^]

If I'm missing something please let me know, any help is greatly appreciated. Thanks my friend Smile | :)

.

Still I am getting the following Error:

Either the .deploy file does not exist in that path on your server, or you didn't configure the MIME type for .deploy files.

If you request http://localhost/WpfBrowserApplication12015/WpfBrowserApplication12015.exe.deploy in your web browser, do you get the file, or do you get an error?

If you get an error, try using failed request tracing[^] to diagnose the problem.

Re: Application download error in XBAP application after deploying the application

21-Sep-16 6:51

So try the failed request tracing, as I suggested.

Either the file doesn't exist, or something isn't configured properly in IIS. Failed request tracing will tell you what the problem is.

Not without seeing the full file.

If you open the XML file in Internet Explorer, you should see a detailed log of the failed request, and the breakdown of what caused the error.

Using a static class to call child Usercontrols functions from a parent window button click event

22-Sep-16 1:46

If you open the XML file in Internet Explorer, you will get a formatted list of errors and warnings.

If you can't work out what they mean, then post the file to a new GitHub Gist[^] and provide the link.

I have a situation where I am trying to change the visibility of StackPanels in a child UserControl from a button in the parent window. I created a custom class below that holds a static reference to the UserControl value and in the UserControl View constructor the user control value is assigned to the static EditWindow class uc static value. Now what I am trying to do is hide and show StackPanels in the child UserControl view the button in the parent window is clicked. When the button is clicked the StackPanels are not changing from Collapsed to Visible. All of the code is below:

EditWindow.cs

public static class EditWindow
{
    public static string buttonString;
    public static Button button;

    // This is the UserControl
    public static View.ApplicationInfoView uc;

}

// UserControl as a View in the parent window:

<v:ApplicationInfoView />

ApplicationInfoView StackPanels

<StackPanel Name="Sp1">

<StackPanel Name="Sp2">

<StackPanel Name="Sp2">

// UserControl - ApplicationInfoView in the constructor

EditWindow.uc = this;

// Button Click event in the Parent Window

private void btnEdit_Click(object sender, RoutedEventArgs)
{
    EditWindow.uc.editAppInfo();
}

// editAppInfo method in the UserControl -  //ApplicationInfoView 

editAppInfo()
{
    EditWindow.uc.sp1.Visibility = Visibility.Collapsed;
    EditWindow.uc.sp2.Visibility = Visibility.Visible;
    EditWindow.uc.sp3.Visibility = Visibility.Visibile;
}

If the StackPanels are "empty", toggling visibility will make no difference unless you use an explicit minimum height, width and / or color in order to "see" them.

Also, the layout (right or wrong) impacts what one sees (in-back versus in-front; etc); regardless of what the "code-behind" is doing.

I have now tried changing the way I am performing my task. Now in my child user control constructor I am loading the UserControl as follows:

// Remember EditWindow is a static class and uc is a static // public value of View.ApplicationInfoView which is the // UserControl that is a View with a base class of // UserControl.

EditWindow.uc = this;

And now calling the method the following on the parent window button click event:

// Remember the StackPanel spGrid is Collapsed onload
private void btn_click(object sender, RoutingEventArgs e)
{
EditWindow.uc.spGrid.Visibility = Visibility.Visible;
}

Now Here is my StackPanel on the child UserControl:

<StackPanel Name="spGrid" Grid.Column="0" Grid.ColumnSpan="4" Grid.Row="2">
    <Grid Name="Grid2">
        <Grid.ColumnDefinitions>

                                <StackPanel  Orientation="Horizontal">

                                    <Image  Source="/Images/Attachments_button.jpg" Margin="50, 0, 0 ,0" Name="PPBottom" Width="Auto"    Height="45"  />
                                </StackPanel>
                                <TextBlock  Height="20"  Width="Auto"  Foreground="#FF004A78" FontSize="12" TextWrapping="WrapWithOverflow" x:Name="Passport2_TextBlock" Text="(Color copy, top and bottom) Perferred           Passport Top    Passport Bottom"  TextAlignment="Left"/>
                            </StackPanel>
                        </StackPanel>

                    </StackPanel>
                </Border>
            </Border>
        </StackPanel>
        </StackPanel>
    </Grid>
</StackPanel>

Now, again the StackPanel I am trying to hide/show is Name="spGrid". It houses my Grid "Grid2". Now this StackPanel is housed in it's own Grid. Shown is the nested Grid. Also, I am only showing you only one of the rows in the nested Grid of StackPanel spGrid. The other rows have the same type of controls. Again I don't know why when my EditWindow static class's UserControl uc set's it's StackPanel spGrid to visible it stil stays hidden.

This is one of those situations where the XAML should be "re-considered". (The "depth" of this simple visual tree is sure ... "deep"...)

Even your top "stack panel" is imbedded in a Grid; so you've still not got the whole picture.

State what you're trying to do from a "user" / functional point-of-view, and you'll probably get some good design answers to get you off with a less "complicated" (XAML) design / approach.

The appropriate way to do this is to create a Tunnelling Routed Event that the Child User control listens to. And make that event fire when you click the button on the parent control. This article on MSDN explains how to declare a Routed Event

How can I call xbap from client browser

Hi All,

I am using a Silverlight listbox on which I display some integers, when I select a particular item of listbox (ie integer), it has to show me the value of that integer. Showing part is working perfect but the problem is when I select one item and then go to another item, silverligh is not clearing the selection of the first one instead keeping the selection on both, which looks weird to customer, any help is appreciated.

Here is my Command

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

    public class RollDiceCommand : ICommand
    {
        private Action _action;
        private Boolean _canExecute;

        public RollDiceCommand(Action _action, Boolean _canExecute)
        {
            this._action = _action;
            this._canExecute = _canExecute;
        }

        bool ICommand.CanExecute(object parameter)
        {
            return _canExecute;
        }

        public event EventHandler CanExecuteChanged;
        void ICommand.Execute(object parameter)
        {
            _action();
        }
    }
}

Here is my other class

namespace RollDiceApp
{
    public class HelperMethods
    {
        public static string GetRootDirectory()
        {

            string uriPath = Application.Current.Host.Source.ToString();
            Uri uri = new Uri(uriPath);
            Uri parent = new Uri(uri, "..");          
            return parent.ToString();
        }
    }
}

Here is my App.xaml

<Application xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
             x:Class="RollDiceApp.App"

<pre>
         >
<Application.Resources>

</Application.Resources>

Hi All,

I have created xbap application and moved the xbap, exe and manifest files into wwroot folder.
Now to be able to use/call this xbap file from clients browser, I have few questions

do I need to create a html file to call this xbap from browser? If I need to, can you please give me the sample tags how to call?
I tried to call xbap it looked like it was executing but did not, it seems like certificates or permissions are the issue, if I want to give certificate or permissions, how can I do it on the Virtual directory? I am using IIS 7
Do I need to install MIME types on IIS to exec my xbap file? Reason is I got a script from msdn which installs it but it was giving me error, if I need to have them installed, is there any better and guaranteed approach to do the same on IIS 7.

I am searching and inquiring with friends and colleagues but anything helps a small code snippet, a link or even a suggestion helps.

Thanks in advance my friends.

Thanks,

Abdul Aleem

WPF Expander

Hello,
i'm working with expanders in MVVM and i trying to get notification in the viewmodel when the expander is already opened and when it's opened i want to make print screen to the expander content.
and the scenario is like this:

1)i open the expander that binded to IsExpanderOpen property in the VM and fill the details i want
2)i close the expander (don't ask why it's only example)
3)press OK to save the details of expander controls in DB
4)the OK i pressed call to realycommand 'OpenExpander()' that execute the line IsExpanderOpen=true
5)then i make print screen to the content of opened expander(but it captures closed expander)

this scenario doesn't work because the viewmodel doesn't know to wait the xaml to be rendered when the expander is opended.
i don't want code behind so is there any way to know when the ui is already render the operation
and only then to trigger the viewmodel?

I haven't tested this but I would imagine it would be as simple as binding an to the Expanded event (can be done with an EventToCommand). However, if it takes the inner content a while to load up; e.g. because you are lazy loading, then you need to transfer the print logic to wait for that instead.

Ok look this is the code of xaml i use event with command and also send the expander as parameter

<expander x:name="AExpander" margin="0,0,0,5" isexpanded="{Binding SectionAExpander}"
="" isenabled="{Binding WasAppNumEntered}" style="{StaticResource LsExpander}">
<behaviors:commandbehaviorcollection.behaviors>
<behaviors:behaviorbinding event="Expanded" command="{Binding OnExpandedCommand}" commandparameter="{Binding ElementName=AExpander}">

<expander.header>

and this is the viewmodel code:

1) this is the command that binded to xaml

public ICommand OnExpandedCommand
{
get
{
if (_onExpandedCommand == null)
{
_onExpandedCommand = new RelayCommand(OnExpanderOpened);
}

return _onExpandedCommand;
}
}

2)this is the function OnExpanderOpened:

private Expander expanderA;
private void OnExpanderOpened(object obj)
{
expanderA = (Expander)obj;

if (expanderA.IsExpanded)//show true
{
CanPrintDataEntry = true;//attached property that call to the print screen function
}
}

so you see expanderA show that it's opened but the render happens after it is true in the VM
and i get print screen with closed expander so is there any way to notify
the viewmodel AFTER xaml is rendered
thank you

Okay, then you are going to have to get to the ContentRendered event (not easily done I'm afraid). To do this, if I were you, I would create a behavior that behaved something like this internally:

AssociatedObject.Loaded += LoadedEvent;
///.....

private void LoadedEvent(object sender, RoutedEventArgs e)
{
  PresentationSource presentationSource = PresentationSource.FromVisual((Visual)sender);
  presentationSource.ContentRendered += ContentRenderedHandler;
}

private void ContentRenderedHandler(object sender, EventArgs e)
{
  ((PresentationSource)sender).ContentRendered -= ContentRenderedHandler;
  // You should be good to go here...
}
