How to change the CarouselItem Image Source at runtime

Hi,

I'm using the RadCarousel, with 7 Images as carousel items. How can I change the image source of the selected carousel item at runtime? For example, I want to open the carouselitem 1 with image A. Later, when the user clicks on the item 1 (and it becomes the Top item), I want to set image B to that item.

Thanks
Ela

Thanks

How to implement non source use of datafilter

Hi

The following little example should illustrate my problem.

I have three classes in my system:

1. Class Person
- Name
- Age.

2. Class Student : Person (Inherites from Person)
- Grade

3. Class Teacher : Person (Inherites from Person)
- Wage level

My system holds a complete list of Teachers and students like

ObservableCollection<Person>

I have different kinds of GUI controls (listview and radCarousel sofar) that binds to this collection. If I use the radFilterData component in source mode then I see only Name and Age in the field selector. I want to be able to see Name, Age, Grade, Wage level eventhough some of them only makes sence according a specific person type. I use ItemProperties and non source mode to archieve that.

My problem is that I am a little bit confused how to do the rest. I have seen the Domain examples but doesn't guite get it. I assume I have to handle this event:

radDataFilter.FilterDescriptors.CollectionChanged += this.OnRadDataFilterDescriptorsChanged;

But how should I do that. I should also say that I have already implemented sorting and grouping using the

CollectionViewSource.GetDefaultView

Hopefully I will be able to have sorting, grouping and filtering working side by side.

[Solved] Custom background in border?

I started with the Telerik WPF Q2 2010 examples.
I went to Controls -> DATA -> GridView -> Appearance -> Custom Row Layout

I am using a slightly modified version of this now. What I want is to change the four gradient stops for the main row background dynamically based on object properties of the binding. The problem is that my template is 75 lines long and I think it seems very inefficient to duplicate this six times (for siz possible gradient values) and use a TemplateSelector. Instead I'd like to modify the border background property.

Here's a small snippet of code:

<ControlTemplate x:Key="TCCustomRowTemplate" TargetType="telerik:GridViewRow">
    <Border x:Name="rowsContainer" Background="#FF525252" Padding="8,8,8,0" >
        <Border x:Name="selectedRow" BorderThickness="1" BorderBrush="#FF000000"
            Background="{StaticResource TC_INRowBackgroundSelected}>

How can I modify this background to be a different static resource dependant on my object?

Tab Scrolling - One Tab at a time

Hi
I've modified the TabControl but would like to force the scrollviewer repeat buttons to scroll one full tab at a time but cannot find a way to do this.

I thought I might be able to add something like Command="ScrollBar.LineDownCommand" to the repeat button - no joy though!

Any help would be much appreciated.

Adding OutlookBarItems to OutlookBar and displaying the content of the OutlookbarItem

Hi,
I am trying to Wrap RadOutlookBar and make MYOUTLOOKBAR so that i can expose only few properties in MYOUTLOOKBAR.
In this senario i need to add radoutlookbarItems to MYOUTLOOKBAR.

Even if i add MYoutlookbarItem to MYOUTLOOKBAR ..In xaml i was able to look at the change.
But in design i dont see any Item getting added to the Outlookbar.

if add content to this Newly added MYOutlookBarItem from properties tab, i get an error message saying that

"Property Value is not Valid"
(in detail: Property "content" does not support string to value conversation)

How to add items to outlookbar so that the items of the outlookbar should support exposed properties of radoutlookbar control?

Here is an example code...for Items property of MyOutlookbar.cs

#region

Property: Items

private MYOutlookBarItemCollection _items;

public MYOutlookBarItemCollection Items

{

get

{

if (_items == null)

{

_items =

new MYOutlookBarItemCollection ();

}

return _items;

}

}

#endregion

The above code exposes the items property in MYoutlookbar

MYOutlookBarItemCollection.cs will be a separate will which contains
public class MYOutlookBarItemCollection: ObservableCollection<MYOutlookBarItem>

{

}

Here is an example code...for content property of MyOutlookbarItem.cs

#region

Property: Content

public object Content

{

get { return (object)GetValue(ContentProperty); }

set { SetValue(ContentProperty, value); }

}

public static readonly DependencyProperty ContentProperty =

DependencyProperty.Register(

"Content", typeof(object), typeof(MyOutlookBarItem),

new FrameworkPropertyMetadata

{

PropertyChangedCallback = (obj, e) =>

{

(obj

as MyOutlookBarItem).UpdateContent((object)e.NewValue);

}

});

private void UpdateContent(object sel)

{

OutlookBarItem.Content = sel;

}

#endregion

Can you guys help me..

Thanks,
Deepz

ItemTemplateSelector Not working

Hello,

The ItemTemplateSelector for the RadTileView does not seem to be working. I can set the property and it is set correctly, but it does not run the SelectTemplate Method. I am using the current Build (0714).

Would someone send code that works with this in the current version?

Thanks,
Matt
