Yes:

    &lt;Border BorderThickness=&quot;1 1 1 0&quot; BorderBrush=&quot;Black&quot;/&gt;

Same as goes for Margin, Padding etc.

And just for fun, to do so in code: 

    var b = new Border(); 
    b.BorderThickness = new Thickness{Top=1, Bottom=0, Left=1, Right=1}; 



I goofed up a merge.  I&#39;d like to revert then try again.  
Is there a way to revert a merge before it is committed?

`hg revert` doesn&#39;t do what I&#39;d like, it only reverts the text of the files.  Mercurial aborts my second attempt at merging and complains original merge is still uncommitted.

Is there a way to undo a merge after an `hg merge` command but before it&#39;s committed?

Can I give default parameters in C#?

In C:

    void fun(int i = 1)
    {
        printf(&quot;%d&quot;, i);
    }

Can we give parameters a default value? Is it possible in C#? If so, can we avoid overloading functions?

It&#39;s always a bad practice to add an optional parameter to an existing function. If you are working on a project which is having to refer the class having a function and we changed a parameter with an optional value, it may throw a run time exception that the method is not found.

This is because we will consider that the if we add an extra optional value, there is no code change required if the function is used in many places.

    function Add(int a, int b);

This will be called using this way:

    Add(10, 10);

But if we add an optional parameter like this,

    function Add(int a, int b, int c = 0);

then the compiler expects

    Add(10, 10, 0);

Actually we are calling like this `Add(10, 10)` and this function won&#39;t be available in that class and causes a run time exception.

This happens for while adding a new parameter to a function which called by a lot of places and I not sure this will happen every time. But I suggest you to overload the function.

Always we need to overload the method which has an optional parameter. Also if you are working with functions having more than one optional parameter, then it&#39;s good to pass the value using the name of the parameter.

    function Add(int a, int b, int c = 0);

It&#39;s always good to call this function using the following way.

    Add(10, 20, c:30);

I am trying to bind to an integer property:


    &lt;RadioButton Content=&quot;None&quot;
                 IsChecked=&quot;{Binding MyProperty,
                             Converter={StaticResource IntToBoolConverter},
                             ConverterParameter=0}&quot; /&gt;


and my converter is:

    
    [ValueConversion(typeof(int), typeof(bool))]
    public class IntToBoolConverter : IValueConverter
    {
        public object Convert(object value, Type t, object parameter, CultureInfo culture)
        {
            return value.Equals(parameter);
        }
    
        public object ConvertBack(object value, Type t, object parameter, CultureInfo culture)
        {
            return value.Equals(false) ? DependencyProperty.UnsetValue : parameter;
        }
    }


the problem is that when my converter is called the parameter is string. i need it to be an integer. of course i can parse the string, but do i have to?

thanks for any help

how to pass an integer as ConverterParameter?

I have a regular DataGrid from WPF 4.0 RTM, where I put data from a database. In order to make clean &amp; light style of `DataGrid` I use a tall/high rows and by default `DataGrid` aligns row content in top vertical position, but I want to set a center vertical alignment.

I already tried to use this property 

    VerticalAlignment=&quot;Center&quot;

in `DataGrid` options, but it doesn&#39;t help me.

Here is an example of XAML-code, describing my `DataGrid` without center vertical alignment:

    &lt;DataGrid x:Name=&quot;ContentDataGrid&quot;
		Style=&quot;{StaticResource ContentDataGrid}&quot;
		ItemsSource=&quot;{Binding}&quot;
		RowEditEnding=&quot;ContentDataGrid_RowEditEnding&quot;&gt;
	&lt;DataGrid.Columns&gt;
		&lt;DataGridTextColumn Header=&quot;UserID&quot;
				Width=&quot;100&quot;
				IsReadOnly=&quot;True&quot;
				Binding=&quot;{Binding Path=userID}&quot; /&gt;
		&lt;DataGridTextColumn Header=&quot;UserName&quot;
				Width=&quot;100&quot;
				Binding=&quot;{Binding Path=userName}&quot; /&gt;
		&lt;DataGridTextColumn Header=&quot;UserAccessLevel&quot;
				Width=&quot;100&quot;
				Binding=&quot;{Binding Path=userAccessLevel}&quot; /&gt;
		&lt;DataGridTextColumn Header=&quot;UserPassword&quot;
				Width=&quot;*&quot;
				Binding=&quot;{Binding Path=userPassword}&quot; /&gt;
	&lt;/DataGrid.Columns&gt;
    &lt;/DataGrid&gt;

Result of executing this code:

![alt text][1]

As you can see all row content has top vertical align.

What do I have to add in order to get center vertical alignment of each row content?

I develop a WPF4 application and in my app I need to let the user select a folder where the application will store something (files, generated reports etc.).

My requirements:

- Ability to see the standard folder tree

- Ability to select a folder

- WPF look &amp; feel, this dialog must look like part of a modern application designed for Windows Vista/7 and not Windows 2000 or even Win9x.

As I understand, until 2010 (.Net 4.0) there won&#39;t be a standard folder dialog, but maybe there are some changes in version 4.0?

Or all what rest to do is use old-school WinForms dialog? If it&#39;s the only way to do what I need, how can I make it closer to Vista/7 style and not Win9x?

On some forums, I saw the implementation of such dialogs but with old ugly icons &#224; la Windows 95. It really doesn&#39;t look nice.

CSS/HTML: Create a glowing border around an Input Field

I&#39;m trying to [make a navbar][1] as an exercise.

I&#39;m using `a:hover` to include a solid border around the button being hovered. However, this makes all the other buttons move by the size of the border.

What is the proper fix to this problem? I know there are others (discussed [here][2]), I specifically tried to make the border &quot;be invisible yet take up space even when not hovered&quot;. I set `border:transparent` hoping it might do what I want, but it did not show take space at all.

I know I could hand pick the border&#39;s color to be equal to the background and make it solid, but this is not what I want. Is there a sane way to solve this issue?

I&#39;ve been trying to get a border on either side of [my white container][1]. It&#39;s just not showing. I&#39;ve tried to put it in three different elements just in case! (see below). Any ideas on how to make it work?

    	background:#F4F4F4;
    	padding-top:5px;
    	border: 3px #CDCDCD;

    	min-height: 100%;
    	height: auto !important;
    	height: 100%;
    	margin: 0 auto;  
    }

    #casing {
    	padding:0px 0px 0px 0px;
    	background:#Fff;

    #cover {

    }

CSS Border Not Working

When required is defined in a form field, Firefox 4 automatically shows a red border to this element, even BEFORE the user hits the submit button.

    &lt;input type=&quot;text&quot; name=&quot;example&quot; value=&quot;This is an example&quot; required /&gt;

I think this is disturbing for the user as he/she asn&#39;t made mistakes at the beginning.

I wnat to hide that red border for the initial state, but show it when the user hits the send button if there is a missing field marked as required.

I looked at `:required` and `:invalid` from new pseudo selector, but the changes are for **before AND after** the validation. (from [https://stackoverflow.com/questions/3809146/firefox-4-required-input-form-red-border-outline][1])

Is there a way to disable the red border before the user submits the form, and show it if there is some missing fields ?

I have this CSS:

Using jQuery, I also added a `border=0` attribute on every image tag. But the border as shown in the image still appears. Any solution?
