RadMaskedDateTimeInput Exception at Design Time

We are using a RadMaskedDateTimeInput in a very simple UserControl.
Everything runs well at runtime, but at design time we get frequently the following exception. If you reload the VS2010-Designer usually the exception vanishes.

-------

System.Exception

Coded UI and RadTreeView: How to navigate through nodes that have not yet been displayed?

I have an application using a WPF RadTreeView control. I try to control the RadTreeView using a Coded UI Test.

Now I found out that the Playback is only able to find nodes of an RadTreeView which have already been displayed in the application. Given
a tree that looks like this:

Node1
Node11
Node12
Node2
Node21
Node22

After application start the RadTreeView only displays the top level nodes:

Node1
Node2

When I now try to find the 'Node11' control:

WpfRadTreeViewItem node = _AppWindow.Navigation.GetNode("Node11");
Click(node);

I get the error: 'The playback failed to find the control with the given search properties'. However, after expanding the Node1 and Node2 manually (and closing them again), the playback is able to locate the control (even if it is not currently displayed in the navigation tree).
I assumed that this is related to the "LoadOnDemand" feature of the RadTreeView, so I tried to set the 'IsLoadOnDemandEnabled'
and the 'IsVirtualizing' properties of the RadTreeView to 'False', but that did not change the behavior.

Is there a way that playback find's the control even if it has been not yet displayed in the navigation tree?
Is there a way to force the RadTreeView to load all subitems even if they are not yet displayed?

While searching for a workaround I tried to expand the root nodes by setting the 'IsExpanded' property to 'True':

WpfRadTreeViewItem node = _AppWindow.Navigation.GetNode(target);
node.IsExpanded = true;

However, if I do this, I get another error 'SetProperty of "IsExpanded" is not supported on control type: TreeItem'.

Why do I get this error?
What can I do to expand the Node by the Playback?
(Klicking on is no good idea since the node may already be expanded.)

Thanks and best regards,
Claudio

Setting Data source for XMLA provder

I have OLAP Cube defined in SQL Server Analysis server and now am trying to connect the RadpIvotGrid (for WPF) and RadPivotFieldList to this Cube. I presume I should create a xmlaDataProvider and then set the connection settings. I cannot seem to get this working nor can I find any detailed instructions. My specific questions are:
1. How do I format the connectionsettings.ServerAddress - do I have to use http: or can I just provide a connection string. Can you provide examples of both of these - my server name is CUBESERVER and its ip address is 192.168.1.117
2. Once I have got a connection I presume I just set the RadPivotGrid and RadPivotFieldList dataprovider to the xmlaDataProvider created in step 1 and 2 above - is this correct:?
3. How then do I specify what fields I want to show in the PivotField List or does it just pick these up from the dataprovider - i.e. the fields in the Cube and what does it pick up - e.g. The measures or the dimensions?
4. Finally do you have any example code (in C#) of connecting to a SQL Server Analysis server and setting the connection etc

I would appreciate your comments - thank you

Update LinkText

Hello!

I am using RadRichTextBox, and in my scenario user can add hyperlinks to RichText to some application entities. Those entities can change their names outside of the richtextbox, so I need to update hyperlink text with corresponding data. But documentation about HyperlinkRangeStart does not give any clues how to update hyperlink text.

Can someone please tell me how can I accomplish my task?

WBR,
Dmitry.

[Solved] issue changing style daybutton

Hey,

I'm creating a proof of concept to test the telerik calendar control. We designed a design for this control but we're having a problem with styling the DayButtonStyle.
We like to change the looks of the buttonchrome in this control because it looks awfull with our design. It is no problem to change this style but when we change the style and we are going to the next month, the days are not refreshing. The days are in the same place as the month before what isn't correct in this new month.

Is there something I am missing? Or is there a solution for this issue? There is not much to find about styling these buttons or issues with it.

Y-Axis IsLogarithmic Property and Pointmarks

I have a chart which implements a Logarithmic Scale for the Y-Axis as described here:
http://www.telerik.com/help/wpf/radchart-features-axes-logarithmic-scale.html

I some cases, when the IsLogarithmic Property is toggled for Line Series types, the Point Marks become skewed. The lines themselves seem to be plotted correctly, but the Point Marks will appear in their old positions. This behavior only occurs for only certain data sets.

Below is an example which demonstrates the problem.

XAML:

<Window x:Class="LogarithmicScale.MainWindow"
