I want whenever an item is added for it to start expanded.

My treeview is bound to a viewmodel.

I am using code examples from the forums to bind the isexpanded to a viewmodel isexpanded property like below.

The code worked for a bit and then recently stopped . the treeview does not render at all if the style is applied. if I remove the style it works fine.

Any ideas. is there a simpler way to do it .

Any help would be appreciated.

I want to put a circle of a certain radius on a map, that can be selected and I can move it around with a mouse.

SelectionChanged event is only available on VisualizationLayer, however I cannot put MapEllipse or MapEllipseView on the layer - I see nothing. With MapEllipse, for example - when I put it onto the InformationLayer it is displayed properly. But I cannot do anything with selection on that layer... I could use EllipseData, but that doesn't have HotSpot property, and I would like to set the hotspot to the center of the shape rather than left upper corner as it is by default.

Do you have any tips how I can reach my goal?

Hi everybody,

I'm using a RadRibbonView. When the window is full screen, i've no problem (file_1).

When the window is more small, the width of RadRibbonView is decreasing, and the RadRibbonTab witdh, too (file_2). The components are grouped in the same menu ("Navigation").

But, the space between the title ("Navigation") and his components is created (file_3), and I can't delete it.

My code :

<telerik:RadRibbonView Grid.Row="0" Grid.Column="1" HelpButtonVisibility="Hidden" ApplicationButtonVisibility="Hidden" 
                                        TitleBarVisibility="Collapsed" HorizontalAlignment="Left" TitleBarBackground="{x:Null}" 
                                        IsMinimizable="False" Height="82">

I've tried to change de Height ("Auto" for example"), but it dosen't work.

<telerik:RadRibbonTab Header="Graphiques" Height="Auto" VerticalAlignment="Top" >

(The all of RadRibbonTab have the similar code)

<telerik:RadRibbonGroup Header="Navigation" Height="Auto" VerticalAlignment="Top">

(The all of RadRibbonGroupe have the similar code)

I am trying to add nodes for a radtreeview from vb. But the property nodes is not getting visibled for radtreeview.

I referred this tutorial to add but when ever i tried to call this Nodes property RadTreeView1.Nodes  its throwing an error as  'Nodes' is not a member of 'Telerik.Windows.Controls.RadTreeView'. 

 Why does it showing like this and whats the workaround for this ..??/

Thanks

Hi to all,

I'm developing a MVVM Application, I have a global context for application, I have a provider class that exposes me a method that returns a List<MyModel>

MyModel is a class that I use internally in application:

My entityframework context (EF5 & FW4.0) exposes MyTable (this table corresponde to MyModel class).

My provider get IQuarable<MyTable> by linq and convert all items in MyModel, then return List<MyModel>.

Now, If I have a lot of records and I have to show all items into ComboBox, I could user VirtualQueryableCollectionView.

But how can I use List<MyModel> to do this? I will get the same result?

Hi,

I'm using a RadScatterSparkline object inside a RadTimeBar. It works perfectly but I would like to make the points bigger because some times they are difficult to see (I'm using the RadScatterSparkline in combination with a RadLinearSparline).

Since I'm adding the RadScatterSparkline dynamically I would like to change the size of the points programmatically.

I've tried setting the Height and Width properties but it did not work.

Do you know if this is possible at all? If so, any idea on how to do it?

Many thanks!

Regards.
