You need to set FocusVisualStyle of each ListBoxItem to null. Steps are bellow

1) Create ItemContainerStyle for the ListBox

    &lt;Style x:Key=&quot;ListBoxItemStyle1&quot; TargetType=&quot;{x:Type ListBoxItem}&quot;&gt;	
	   &lt;Setter Property=&quot;FocusVisualStyle&quot; Value=&quot;{x:Null}&quot;/&gt; ....


2) Set that style to Listbox

    &lt;ListBox ItemContainerStyle=&quot;{DynamicResource ListBoxItemStyle1}&quot;




There’s not standard way to check if a MySQL user exists and based on that drop it. Are there any workarounds for this?  

Edit:  I need a straight way to run this without throwing up an error  
e.g.

In my Visual Studio instance, even if I just wrote a single line of return in a C# console application, it will take me a minute after pressing &lt;kbd&gt;F5&lt;/kbd&gt; to execute the actual code (I mean the time it takes to stop on the single return statement after pressing &lt;kbd&gt;F5&lt;/kbd&gt; -- I set a breakpoint on the return statement in the `main` function). What is wrong? Is there a check list?

WPF: Remove dotted border around focused item in styled listbox

<p>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?</p>


&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 am currently working with `Panel`s in WPF, and I noticed that as regards the `Width` and `Height` properties, there are also two other properties called `ActualWidth` and `ActualHeight`.

&gt; `ActualWidth`
&gt; 
&gt; Gets the rendered width of this
&gt; element. This is a dependency
&gt; property. (Inherited from
&gt; FrameworkElement.)
&gt; 
&gt; `Width`
&gt; 
&gt; Gets or sets the width of the element.
&gt; This is a dependency property.
&gt; (Inherited from FrameworkElement.)

*Reference: [MSDN][1]*

Can anyone point out **the differences between the two and when to use either one ?**

If you set `ResizeMode=&quot;CanResizeWithGrip&quot;` on a WPF `Window` then a resize grip is shown in the lower right corner, as below:

![][1]

If you set `WindowStyle=&quot;None&quot;` as well the title bar disappears but the grey bevelled edge remains until you set `ResizeMode=&quot;NoResize&quot;`.  Unfortunately, with this combination of properties set, the resize grip also disappears.

I have overridden the `Window`&#39;s `ControlTemplate` via a custom `Style`.  I want to specify the border of the window myself, and I don&#39;t need users to be able to resize the window from all four sides, but I do need a resize grip.

Can someone detail a simple way to meet all of these criteria?

1. **Do not** have a border on the `Window` apart from the one I specify myself in a `ControlTemplate`.
2. **Do** have a working resize grip in the lower right corner.
3. **Do not** have a title bar.

In my Silverlight project, I would like to make an assembly which contains .xaml that can&#39;t be seen from outside of the assembly. However, there is no clear way I can do this. When I modify the access modifier on the .xaml.cs file, the compiler tells me:

    Partial declarations of &quot;My xaml class here&quot; have conflicting accessibility modifiers	

In the xaml file itself, there doesn&#39;t seem to be a place to put my access modifier. In short, how do I set the class associated with my xaml file to `internal`?

I&#39;m trying to bind to a `Readonly` property with `OneWayToSource` as mode, but it seems this cannot be done in XAML:

    &lt;controls:FlagThingy IsModified=&quot;{Binding FlagIsModified, 
                                              ElementName=container, 
                                              Mode=OneWayToSource}&quot; /&gt;

I get: 

&gt; The property &#39;FlagThingy.IsModified&#39; cannot be set because it does not have an accessible set accessor.

`IsModified` is a readonly `DependencyProperty` on `FlagThingy`. I want to bind that value to the `FlagIsModified` property on the container. 

To be clear: 

    FlagThingy.IsModified --&gt; container.FlagIsModified
    ------ READONLY -----     ----- READWRITE --------

Is this possible using just XAML?

---
**Update:** Well, I fixed this case by setting the binding on the container and not on the `FlagThingy`. But I&#39;d still like to know if this is possible.

I have a few WPF applications and I want all my styles to be in a shared assembly instead of declaring them in each application separately.

I am looking for a way so I don&#39;t have to change all my `Style=&quot;{StaticResource BlahBlah}&quot;` in the existing applications; I just want to add the reference to this style assembly, and delete it from the current application, so it&#39;s taken from the assembly.

I was wondering how people handle a ListBox control that has no items? e.g. I want to bind a list of search results but if no results are found i would like to display &quot;No results found&quot;.

I&#39;m trying to write a WPF application for displaying images from a selection.
I want to display all of the available images in a banner along the top of the window, and display the main selected image in the main window for further processing.

If I wanted the list on the &lt;i&gt;Left&lt;/i&gt; of the window, displaying the images vertically, I can do this quite elegantly using databinding.

It seems that when a WPF application starts, nothing has focus.

This is really weird. Every other framework I&#39;ve used does just what you&#39;d expect: puts initial focus on the first control in the tab order. But I&#39;ve confirmed that it&#39;s WPF, not just my app -- if I create a new Window, and just put a TextBox in it, and run the app, the TextBox doesn&#39;t have focus until I click on it or press Tab. Yuck.

My actual app is more complicated than just a TextBox. I have several layers of UserControls within UserControls. One of those UserControls has Focusable=&quot;True&quot; and KeyDown/KeyUp handlers, and I want it to have the focus as soon as my window opens. I&#39;m still somewhat of a WPF novice, though, and I&#39;m not having much luck figuring out how to do this.

If I start my app and press the Tab key, then focus goes to my focusable control, and it starts working the way I want. But I don&#39;t want my users to have to hit Tab before they can start using the window.

I&#39;ve played around with FocusManager.FocusedElement, but I&#39;m not sure which control to set it on (the top-level Window? the parent that contains the focusable control? the focusable control itself?) or what to set it to.

What do I need to do to get my deeply-nested control to have initial focus as soon as the window opens? Or better yet, to focus the first focusable control in the tab order?

WPF and initial focus

I have a WPF UserControl with Focusable=&quot;True&quot;. It&#39;s the only focusable control in the window.

Whenever the user presses Tab or Alt (and especially when they Alt+Tab to another application), my UserControl acquires a dotted-line border, aka focus rectangle. The focus rectangle then stays there until the window is closed.

How can I prevent my UserControl from ever displaying this focus rectangle?

&lt;h3&gt;Edit&lt;/h3&gt;

It turns out the focus rectangle wasn&#39;t actually being displayed by my UserControl. My Focusable UserControl contained another UserControl that, in turn, contained an ItemsControl, and the ItemsControl is what was showing the focus rectangle.

When I added FocusVisualStyle=&quot;{x:Null}&quot; to the ItemsControl, the focus rectangle went away.

This question has been asked in a few different formats but I can&#39;t get any of the answers to work in my scenario.

I am using jQuery to implement command history when user hits up/down arrows. When up arrow is hit, I replace the input value with previous command and set focus on the input field, but want the cursor always to be positioned at the end of the input string.

My code, as is:

    $(document).keydown(function(e) {
      var key   = e.charCode ? e.charCode : e.keyCode ? e.keyCode : 0;
      var input = self.shell.find(&#39;input.current:last&#39;);
      
      switch(key) {
        case 38: // up
          lastQuery = self.queries[self.historyCounter-1];
          self.historyCounter--;
          input.val(lastQuery).focus();
    // and it continues on from there

I&#39;m trying to design some HTML/CSS that can put a border around specific rows in a table. Yes, I know I&#39;m not really supposed to use tables for layout but I don&#39;t know enough CSS to completely replace it yet.

Anyways, I have a table with multiple rows and columns, some merged with rowspan and colspan, and I&#39;d like to put a simple border around parts of the table. Currently, I&#39;m using 4 separate CSS classes (top, bottom, left, right) that I attach to the `&lt;td&gt;` cells that are along the top, bottom, left, and right of the table respectively.

Is there any easier way to do what I want? I tried applying top and bottom to a `&lt;tr&gt;` but it didn&#39;t work. (p.s. I&#39;m new to CSS, so there&#39;s probably a really basic solution to this that I&#39;ve missed.)

**note:** I do need to have multiple bordered sections. The basic idea is to have multiple bordered clusters each containing multiple rows.

Border around specific rows in a table?

I&#39;m working with the `textarea` element in HTML and want to remove the border of the box. I also want to align the text in the bottom of my `textarea`.

Removing the textarea border in HTML

I am trying to figure out how to add border only inside the table. When I do:

    table {
        border: 0;
    }
    table td, table th {
        border: 1px solid black;
    }

The border is around the whole table and also between table cells. What I want to achieve is to have border only inside the table around table cells (without outer border around the table).

Here is markup I&#39;m using for tables (even though I think that is not important):

    &lt;table&gt;
        &lt;tr&gt;
            &lt;th&gt;Heading 1&lt;/th&gt;
            &lt;th&gt;Heading 2&lt;/th&gt;
        &lt;/tr&gt;
        &lt;tr&gt;
            &lt;td&gt;Cell (1,1)&lt;/td&gt;
            &lt;td&gt;Cell (1,2)&lt;/td&gt;
        &lt;/tr&gt;
        &lt;tr&gt;
            &lt;td&gt;Cell (2,1)&lt;/td&gt;
            &lt;td&gt;Cell (2,2)&lt;/td&gt;
        &lt;/tr&gt;
        &lt;tr&gt;
            &lt;td&gt;Cell (3,1)&lt;/td&gt;
            &lt;td&gt;Cell (3,2)&lt;/td&gt;
        &lt;/tr&gt;
    &lt;/table&gt;

And here are some basic styles I apply to most of my tables:

    table {
        border-collapse: collapse;
        border-spacing: 0;
    }

How can I apply a border only inside a table?

As you can see in [this picture][1], I&#39;ve got an orange `div` inside a green `div` with no top border. The orange `div` has a `30px` top margin, but it&#39;s also pushing the green `div` down. Of course, adding a top border will fix the issue, but I need the green `div` to be top borderless. What could I do?

&lt;!-- begin snippet: js hide: false --&gt;

CSS: Margin-top when parent&#39;s got no border

When an HTML element is &#39;focused&#39; (currently selected/tabbed into), many browsers (at least Safari and Chrome) will put a blue border around it.

For the layout I am working on, this is distracting and does not look right.

    &lt;input type=&quot;text&quot; name=&quot;user&quot; class=&quot;middle&quot; id=&quot;user&quot; tabindex=&quot;1&quot; /&gt;

Firefox does not seem to do this, or at least, will let me control it with:

    border: x;

If someone can tell me how IE performs, I would be curious. 

Getting Safari to remove this little bit of flare would be nice.
