Hi,

 I'm building a DLL which include multiples usercontrols and multiples Telerik Controls and I would like to know if it's possible to define the Office2013 theme at one place for my whole DLL instead of declaring it in each usercontrol which contain a Telerik Control???

 

Thank's

Alain

Hi

I have a gridview which is supposed to show the Nace codes of companies. A Nace Code consists of two strings: The Code and the Name (the Code is a number, but it's type is a string).

In the cells, I want to write: "Code: Name". When the user sorts this column, I want the sorting to be on the Code.
For instance:
3012: Boots- und Yachtbau
9311: Betrieb von Sportanlagen

When the nace code is grouped, I want the headers to be "Name (Code)". When the user sorts the groups, I want the sorting to be on Name:
For instance:
Bibliotheken und Archive (9101)
Boots- und Yachtbau (3012)

I have an Entity with a property named NaceCodeObject which has 2 properties: NaceCode and IndustryName

I can create a GridViewDataColumn which - by the way of a converter and concarding the two properties into a single string - shows me the data I want in the Group header and in the cell. But it seems like SortMemberPath uses the value DataMemberBinding, not the value of the group header for sorting the groups.

How can I solve this problem? Is there any way to sort a column one way when just displaying the rows and another way when grouping?

Hi,

I'm trying to use approach described here (http://www.telerik.com/community/forums/winforms/property-grid/binding-to-datatable.aspx) with wpf RadropertyGrid.

In my scenario, I have an API that returns list of properties for particular instance. That means that properties are resolved at runtime for particular instance. Each instance can have different properties.
*property is described as PropertyName (string), PropertyValue (string), PropertyType(enum).

CustomTypeDescriptor is ideal solution for me. I can map the PropertyType enum to .net types and convert the PropertyValues from strings to strongly-typed values. This way I can benefit from auto generated propertygrid and default editortemplates.

The only problem is, that wpf RadPropertyGrid invokes TypeDescriptionProvider just with Type, and don't pass object instance as parameter. You should use TypeDescriptor.GetProperties(object instance) instead of TypeDescriptor.GetProperties(Type type).


In this callstack you can see that you use TypeDescriptor with object's type insead of instance:

Hi

I'm using RadBook and Pdf viewer as follow:

 Xaml Code:

C# Code:

Everything seems to work fine!

But the problem is when I Load a file and start browsing pages, and monitor it on Task Manager, memory grows too high (i.e. more than 2GB)

Look at the attached files, one from Task manager and one from ANTS Memory Profiler!

 What's wrong with my code? Should I do some extra work like releasing objects, pages, ... any thing!?

When using the Telerik example from http://docs.telerik.com/devtools/wpf/controls/dragdropmanager/how-to/howto-draganddrop-within-radgridview.html dragging an item to the empty space in the RadGridView causes the row to go to the top of the list. Is this the desired behavior? Is there a way to disable it?

 I have attached a picture of dragging to the whitespace. The "spike" row is the last row. If I drag the "spike" row to the bottom whitespace, the "spike" row will become the top row in the list.

Your have a fantastic suite of products.  Congrats from a 35 year veteran of application development (think COBOL)...    Your documentation/examples are prolific and very helpful, but as a relative newcomer to both WPF/XAML (as well as Telerik)  I am having a hard time using many of the code samples in conjunction with others.  Some are operating in different contexts from others and have underlying schemes using seemingly incompatible techniques.   Not a criticism, but trying to be helpful to your already excellent support. 

I'm trying to do 3 things, and I've at least attempted to build and execute the following examples ( as well as several from the awesome Demo UI). Although I've been able to produce all of these individually from demo/sample code, I have not been able to combine them all successfully to meet my requirements.

What I'm trying to do is 
  * Use C# code to build the list of items to render.  Most sample code has hard coded items (ellipses, rectangles, pin points, etc)  , and when I introduce DataContext and ItemTemplate And ItemsSource, and Resource etc, either the xaml pre-processing in VS design time throws errors or the executing code doesn't work. 
  * I need to use the virtualization techniques so that at low zoom levels, the user can see shapes (ellipses), and when zooming in, the shapes remain the same size on the screen, i.e. don't end up being bigger than entire cities.  (http://www.telerik.com/forums/locate-a-shape-and-change-size-according-to-zoom-level) 
  * I need to be able to respond to a user click on a shape and change the appearance to be "selected", i.e. HighlightShapeFill  using the method in http://docs.telerik.com/devtools/wpf/controls/radmap/features/visualization-layer/shape-appearance
  * I'm also probably going to need clustering, but I haven't tried messing around with that concept yet.

I'm not sure what code to post for you to review ... I've got all of this stuff working individually,  I haven't been able to combine them into a single code base. 

Our basic architecture and business is: 
  * The Map control has a VisualizationLayer, and the code behind assigns the ItemsSource to a public property (ObservableCollection of "MapItems")  in the constructor.  This collection get added to no problem, the shapes show up as expected on the map.
  * There are a number of different types of items to render, each type will has a set of appearance attributes as defined in a database, such as fill color, stroke color, size, and in some cases perhaps shape (ellipses vs. square, vs polygon, etc)  
  * When user asks for "nodes" to be placed on map, the C# code creates a new  "MapItem" object with appropriate properties, adds it to the collection of MapItems which are the ItemsSource to the VisualizationLayer.  In the current set up the layer has an ItemTemplate which has a DataTemplate, which binds to MapItem properties for color, size etc.   This works fine by itself.   It's just when I try to bring in the ShapeFill (Highlighted) stuff, and the Virtualization stuff .. nothing works .. at all. 

p.s. thanks for putting up with all of us English speakers and for showing you own neighborhood in many of the examples.  We here in the U.S. need that ;=)  .. badly.  Any hints would be most appreciated. 

благодаря

NOTE:  As it is, we are not able to effectively use INotify in .Net to truly bind WCF UI components.  We are running under some higher level Microsoft frameworks that seem to be interfering (Prism).  So for now all of our code has to run in the code behind, constantly resetting DataContexts and ItemsSources to refresh the UI... ugly, yes, and hopefully resolved before too long. ;-)

Hello everybody,
is it possible to define dynamic pages on the RadWizard Control or create the pages based on a List/Observable collection?

I would like, based on a property, to create or skip the WizardPages...

Many thanks for the answer
Dino

This is a usability issue with the Wizard. 

 I think it would be better to have the Finish button where the Cancel button currently is on the last page of the Wizard.

 This is because users (and I certainly do) will mistakenly tend to click in the same place as Next to complete what they have been doing, only to find that they have actually cancelled the wizard and possibly lost all their processing.

 

This would also make the Telerik wizard consistent with other kinds (e.g. Installation wizards).

 

 

 

Hi,

 Suppose that I want to implement custom IAppointment, IRecurrenceRule, IExceptionOccurrence. (for database purpose for sample like explain in your documentation). I don't want inherited from telerik class but implement myself interfaces.

 If I want to add feature to export schedule in ics format, I can use your helper to do that like this :

 

 

But your exporter make assumption on IExceptionOccurence and try to cast it in telerik class, and in my case it raise an exception :

"Impossible d'effectuer un cast d'un objet de type 'CustomExceptionOccurenceModel' en type 'Telerik.Windows.Controls.ScheduleView.ExceptionOccurrence'."

This behaviour is not really in phase with Appointment and RecurrenceRule, the helper don't suppose that IAppointment and IRecurrenceRule are telerik class. With do you have exception for IExceptionOccurrence ?

Hi,
Is there any limit for tree layout? There are 1100 items and 1200 connections in the diagram. And when applying layout throw stackoverflowexception. Sugiyama Layout working correctly. And tree layout working small diagram( 10 Items, 9 Connections). But in large one, not working. I believe Tree DataStructure function generally recursive one. So It caused the StackoverflowException.
Thanks in advance.
