How Datacontext is specified can not understand - wpf

Question

Here in mMaterialCentreGroupListView.xaml file, this line is written for MaterialCentreGroupView . But I can not see any data context for accessing viewmodel's property. It is working good. Below is code.
<vw:MaterialCentreGroupView
Style="{StaticResource DetailedViewStyle}"
DataContext="{Binding SelectedMaterialCentreGroup}"/>
the view
<UserControl x:Class="MyBooks.View.MaterialCentreGroupView"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
MinWidth="290" MaxWidth="290" Padding="20"
Background="#eee">
<UserControl.Resources>
<ResourceDictionary Source="ViewResources.xaml" />
</UserControl.Resources>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Label
Grid.Row="0" Grid.Column="0"
Content="{Resx ResxName=MyBooks.Properties.Strings, Key=AccountCategoryListView_Name_Label}"
HorizontalAlignment="Right"/>
<TextBox
x:Name="CategoryName"
MaxLength="50"
Style="{StaticResource FormControlStyle}"
Grid.Row="0" Grid.Column="1" Grid.ColumnSpan="2"
Text="{Binding Path=Name, ValidatesOnDataErrors=True, UpdateSourceTrigger=PropertyChanged}"/>
Please explain to me what happen and how binding is occur?

Answer 1

I would assume the DataContext is either set in the code-behind (file named the same as the .xaml file but with .cs extension). Look for code like DataContext = new SomeViewModel();
Or, if this UserControl is being used within another control, the DataContext could be either explicitly set on it or, if not, it would be inherited from its parent (which may or may not be inherited from its parent, and so on, if not set explicitly in either the XAML or code-behind).

Answer 2

look 'Resx' binding
<Label
Grid.Row="0" Grid.Column="0"
Content="{Resx ResxName=MyBooks.Properties.Strings, Key=AccountCategoryListView_Name_Label}"
HorizontalAlignment="Right"/>
