wpf - MultiBinding to an ObservableCollection -


I am working in a list of ViewModel with wpf and multibinding.

Suppose I have an observation resolution, the same type of view modal is as follows:

code: 

  public class ShapeVM {color of public color {Get; Set; } Public string name {get; Set; }} OverviewCollection Size = IBM = New Observational Collection (); ShapeVMs.Add (...); ShapeVMs.Add (...); ShapeVMs.Add (...); ShapeVMs.Add (...); ShapeVMs.Add (...); // In the archive size of 5 sizes I see   
:  
   & Lt; / UserControl & gt;   
 Is it possible that whenever the chosen color of colored color changes, then the size of the size of the 5 size will automatically change to the selected color of the color box?  
 If I set the DataContext of UserControl to one size or size, then only the sizes of the same size will change.  
 However, at the same time I would like to change 5 SPVM, the color of the ColorBox has changed.  
 
 
 Another simple solution is your problem  
  & lt; Combo box x: name = "cbb" grid. Value = "{binding path = selected collar, element name = clobod}" selected valuepath = "color" />. & Lt; Color box x: name = "clrbox" />   
 I hope this will help one.

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
