It&#39;s hard to guess without code, but you should be able to set the BindingMode to OneWay.

    &lt;TextBox Text=&quot;{Binding Path=MyProperty, Mode=OneWay}&quot; /&gt;

or from code:

    Binding binding = new Binding();
    binding.Mode = BindingMode.OneWay;



I have a search form with a number of text inputs &amp; drop downs that submits via a GET. I&#39;d like to have a cleaner search url by removing the empty fields from the querystring when a search is performed.

    var form = $(&quot;form&quot;);  
    var serializedFormStr = form.serialize();  
    // I&#39;d like to remove inputs where value is &#39;&#39; or &#39;.&#39; here
    window.location.href = &#39;/search?&#39; + serializedFormStr

Any idea how I can do this using jQuery?

I&#39;ve a read only property I need to display in a textbox, and getting this error at runtime. I&#39;ve set `IsEnabled=&quot;False&quot;`, `IsReadOnly=&quot;True&quot;` - no luck.
Other searches say the readonly should fix it, but not for me.
I&#39;ve got an ugly workaround by adding a dummy setter...

I&#39;m using some Images in my WPF applcation.

XAML:

    &lt;Image Name=&quot;ImageOrderedList&quot;
           Source=&quot;images/OrderedList.png&quot;
           ToolTip=&quot;Ordered List&quot;
           Margin=&quot;0,0,5,5&quot;
           Width=&quot;20&quot;
           Height=&quot;20&quot;
           SnapsToDevicePixels=&quot;True&quot;
           MouseUp=&quot;Image_MouseUp&quot;
           MouseEnter=&quot;Image_MouseEnter&quot;
           MouseLeave=&quot;Image_MouseLeave&quot; /&gt;

But, they appear fuzzy.

Why doesn&#39;t that `SnapsToDevicePixels=&quot;True&quot;` line prevent this problem?


My images are blurry! Why isn&#39;t WPF&#39;s SnapsToDevicePixels working?

I would like to select a WPF TreeView Node on right click, right before the ContextMenu displayed.

I have a horizontal listbox with a custom controlIemplate. The selected item gets a dotted frame when focused. Anyone know how to get rid of it?

WPF: Remove dotted border around focused item in styled listbox

&gt; **NOTE** I have asked the related question: [How to combine DataTrigger and EventTrigger?](https://stackoverflow.com/questions/1679391/wpf-how-to-combine-datatrigger-and-eventtrigger)

I have a list box containing several items.  The item&#39;s class implements `INotifyPropertyChanged` and has a property `IsAvailable`.  I use that property to indicate unavailable options in the list using a different colour.

However, if a selected item is not available, then the foreground colour should be red.

    &lt;ListBox&gt;
      &lt;ListBox.Resources&gt;
        &lt;DataTemplate DataType=&quot;{x:Type local:InstitutionViewModel}&quot;&gt;
          &lt;TextBlock Name=&quot;Name&quot; Text=&quot;{Binding Name}&quot;/&gt;
          &lt;DataTemplate.Triggers&gt;
            &lt;DataTrigger Binding=&quot;{Binding IsAvailable}&quot; Value=&quot;False&quot;&gt;
              &lt;Setter TargetName=&quot;Name&quot; Property=&quot;Foreground&quot; Value=&quot;#888&quot;/&gt;
            &lt;/DataTrigger&gt;
          &lt;/DataTemplate.Triggers&gt;
        &lt;/DataTemplate&gt;
      &lt;/ListBox.Resources&gt;
    &lt;/ListBox&gt;

I use the above data trigger to grey out unavailable items.

The problem I&#39;m facing is that the fact that the item is selected has nothing to do with the underlying data to which the template is bound.  What I really want is some kind of multi-trigger that supports both a regular `Trigger` on a dependency property (`ListBoxItem.IsSelected`) along with a `DataTrigger` on the bound data item.

Can this be done without introducing the concept of selection into my view model?

_For anyone wondering why I do not disable unavailable items, understand that it is a requirement of the application that unavailable options may be selected.  There are actually a few list boxes, and selection in one effects what&#39;s available in the others.  I cannot disable the items as the user would not be able to change their minds or explore different combinations if items were disabled based upon earlier selections._



WPF - How to combine DataTrigger and Trigger?

I&#39;ve got a WPF application with these three types of things...

  - WindowMain
  - UserControlZack
  - WindowModal

UserControlZack1 sits on my WindowMain...


    &lt;Window x:Class=&quot;WindowMain&quot;
            xmlns=&quot;http://schemas.microsoft.com/winfx/2006/xaml/presentation&quot;
            xmlns:x=&quot;http://schemas.microsoft.com/winfx/2006/xaml&quot;
            xmlns:local=&quot;clr-namespace:ProjectName&quot;
            ...
            Name=&quot;WindowMain&quot;&gt;
        &lt;Grid&gt;
            ...
            &lt;local:UserControlZack x:Name=&quot;UserControlZack1&quot; ... /&gt;
            ...
        &lt;/Grid&gt;
    &lt;/Window&gt;

UserControlZack1 displays a WindowModal dailog box...

&lt;pre&gt;
Partial Public Class UserControlZack

   ...

    Private Sub SomeButton_Click(...)
        &#39;instantiate the dialog box and open modally...
        Dim box As WindowModal = New WindowModal()
        box.Owner = ?????
        box.ShowDialog()
        &#39;process data entered by user if dialog box is accepted...
        If (box.DialogResult.GetValueOrDefault = True) Then
            _SomeVar = box.SomeVar
            ...
        End If
    End Sub

End Class
&lt;/pre&gt;

How do I set box.Owner to the correct Window, my running instance of WindowMain?

I cannot use `box.Owner = Me.Owner`, because &quot;&#39;Owner&#39; is not a member of &#39;ProjectName.UserControlZack&#39;.&quot;

I cannot use `box.Owner = Me.Parent`, because that returns a Grid, not the Window.

I cannot use `box.Owner = WindowMain`, because &quot;&#39;WindowMain&#39; is a type and cannot be used as an expression.&quot;

I&#39;m trying to get images to display in a WPF ListView styled like a WrapPanel as described in this old ATC Avalon Team article: [How to Create a Custom View][1].

&lt;img src=&quot;http://i.stack.imgur.com/IFIg5.png&quot; width=&quot;300&quot; height=&quot;200&quot; /&gt;


When I try to populate the ListView with a LINQ-to-Entities queried collection of ADO.NET Entity Framework objects I get the following exception:

**Exception**

&gt; Items collection must be empty before
&gt; using ItemsSource.

My code&amp;hellip;

**Visual Basic**

    Private Sub Window1_Loaded(...) Handles MyBase.Loaded
        ListViewImages.ItemsSource = From g In db.Graphic _
                                     Order By g.DateAdded Ascending _
                                     Select g
    End Sub

**XAML**

    &lt;ListView Name=&quot;ListViewImages&quot;
              SelectionMode=&quot;Single&quot;
              ItemsSource=&quot;{Binding}&quot;&gt;
        &lt;local:ImageView /&gt;
    &lt;/ListView&gt;

I put a breakpoint on that line.  `ListViewImages.ItemsSource` is `Nothing` just before the LINQ assignment.

&quot;Items collection must be empty before using ItemsSource.&quot;

In Common Lisp you can do this:

    (defun foo (bar &amp;key baz quux)
      (list bar baz quux))

    (foo 1 :quux 3 :baz 2) ; =&gt; (1 2 3)

Clojure doesn&#39;t have keyword arguments.  One alternative is this:

    (defn foo [bar {:keys [baz quux]}] 
      (list bar baz quux))

    (foo 1 {:quux 3 :baz 2}) ; =&gt; (1 2 3)

That&#39;s too many nested brackets to have to type and read all the time.  It also requires an explicit hash-map to be passed in as an argument rather than a flat list.  

What&#39;s the most idiomatic Clojure equivalent of keyword arguments that doesn&#39;t look someone set off a punctuation bomb?

In WPF, Can I use binding with values defined in Settings? If this is possible, please provide a sample.

Bind to a value defined in the Settings

I have a WPF xaml file describing a section of a GUI and I&#39;d like the enabling/disabling of a particular control to be dependent on two others. The code looks something like this at the moment:

    &lt;ComboBox Name=&quot;MyComboBox&quot;
              IsEnabled=&quot;{Binding ElementName=SomeCheckBox, Path=IsChecked}&quot;/&gt;

But I&#39;d like it to be dependant on another checkbox as well so something like:

    &lt;ComboBox Name=&quot;MyComboBox&quot;
              IsEnabled=&quot;{Binding ElementName=SomeCheckBox&amp;AnotherCheckbox, Path=IsChecked}&quot;/&gt;

What&#39;s the best way to go about that? I can&#39;t help feeling I&#39;m missing something obvious or going about this the wrong way?
