Generate a comma separated string from an IEnumerable object

string.join(",", Contacts.Select(x=>x.Name); //Name is a property of an object(Contact) in the list of Contacts

Simple yet effective way to find if IEnumerable has elements or not

bool IsEmpty(IEnumerable en)
{
    foreach(var c in en) { return false; }
    return true;
}

How do you force authors or template stylists to force add a control

How do you force authors or template stylists to force add a control

Solution- Provides template authors the information that these parts are required for styling this control -more like a contract

[TemplatePart [Name=TextBlockPart, Type =typeof(TextBlock)))

public class MyControl : Control

{

private const string TextBlockPart as PART_TextBlock;

TextBlock textblock;

protected TextBlock Textßlock

get { return textblock;}
set
{
if (textßlock is null)

(

textblock.Textlnput-= new TextCompositionEventHendler(textblockTextlnput)

WPF MultiBindng Converter example

Without Converter
<TextBlock.Text>
    <MultiBinding StringFormat="{}[{0} - {1}]">
        <Binding Path="Min" FallbackValue=""/>
        <Binding Path="Max" FallbackValue=""/>
    </MultiBinding>
</TextBlock.Text>
</TextBlock>




Using Converter
public class RangeMultiValueConvertor : IMultiValueConverter
   {
       public object Convert(object[] values, Type targetType, object parameter, CultureInfo culture)
       {
           if (values == null) return string.Empty;
           if (values[0] == DependencyProperty.UnsetValue || values[1] == DependencyProperty.UnsetValue)
           {
               return string.Empty;
           }
           return (string.Format("[{0} - {1}]", values[0], values[1]));
       }
 
       public object[] ConvertBack(object value, Type[] targetTypes, object parameter, CultureInfo culture)
       {
           return null;
       }
   }

<local:RangeMultiValueConvertor x:Key="rangeConverter"/>



<TextBlock.Text>
    <MultiBinding  Converter="{StaticResource rangeConverter}">
        <Binding Path="Min"/>
        <Binding Path="Max"/>

Solution for textBox text change not updating the view model/model

<TextBox Name="textBox1"
      Height="23" Width="463"
      HorizontalAlignment="Left" 
      Margin="12,12,0,0"   
      VerticalAlignment="Top"
      Text="{Binding OriginalText, UpdateSourceTrigger=PropertyChanged}" /> 

MSDN How to: Control When the TextBox Text Updates the Source:

The TextBox.Text property has a default UpdateSourceTrigger value of LostFocus. This means if an application has a TextBox with a data-bound TextBox.Text property, the text you type into the TextBox does not update the source until the TextBox loses focus (for instance, when you click away from the TextBox).

If you want the source to get updated as you are typing, set the UpdateSourceTrigger of the binding to PropertyChanged. In the following example, the Text properties of both the TextBox and the TextBlock are bound to the same source property. The UpdateSourceTrigger property of the TextBox binding is set to PropertyChanged.

Serialization Exception: PropertyChangedEventManager is not serializable

Since events are non serializable, here is the way out to deal the problem when serializing model classes which have a property changed event to notify the view model classes:

http://www.primordialcode.com/blog/post/serialization-exception-propertychangedeventmanager-serializable

[NonSerialized]
private PropertyChangedEventHandler _PropertyChanged;
 
public virtual event PropertyChangedEventHandler PropertyChanged
{
  add { _PropertyChanged += value; }
  remove { _PropertyChanged -= value; }
}
