WPF - Retrieve the object binded instead of a single property of the object

I have a checkbox and a textblock inside a stackpanel. When the textblock is clicked, the checkbox should be checked. Actually, it is a set of checkboxes and set of text blocks. Need to retrieve the value ID ( this is a property of the class "SomeClass" of the checkbox. But what has been binded to the Textblock is the name. My question is how do I retrieve the the whole object ?

  <ListView>
     <GridView>
         <GridViewColumn>
               <GridViewColumn.CellTemplate>
                    <DataTemplate>
                        <ItemsControl ItemSource="{Binding SomeClass} ">
                              <ItemsControl.ItemTemplate>
                                  <DataTemplate>
                                    <StackPanel>

                                        <CheckBox...../>
                                        <TextBlock ...Text={Binding Name}/>

                                    </StackPanel>
                                  </DataTemplate>
                               </ItemsControl.ItemTemplate>
                           </ItemsControl>
                       </DataTemplate>
                    </GridViewColumn.CellTemplate>
             </GridViewColumn>                     
      </GridView>
    </ListView>

I am making use of the MouseLeftButton event of TextBlock. I can retrieve the Name, but what I need is the whole obect itself so that I can retrieve the ID property . Any solution to this ?
