System.IO.FileLoadException on version 2010.3.1227.40

I get the following error in the designer of VS2010. The project compiles and runs fine, but the designer has this error. I've checked all the references and I am not referencing any older versions anywhere. I've cleaned and rebuilt the solution and it still doesn't work. I've also added the loadFromRemoteSources option to the app.config. Still no good.

System.IO.FileLoadException

System.NotSupportedException

An attempt was made to load an assembly from a network location which would have caused the assembly to be sandboxed in previous versions of the .NET Framework. This release of the .NET Framework does not enable CAS policy by default, so this load may be dangerous. If this load is not intended to sandbox the assembly, please enable the loadFromRemoteSources switch. See http://go.microsoft.com/fwlink/?LinkId=155569 for more information.

ScrollIntoView and BringIntoView do not work

Hello,

I'm attempting to scroll the selected item into view. The item is not null. I have tried the following methods:

mainGrid.ScrollIntoView(mainGrid.SelectedItem);

mainGrid.BringIndexIntoView(mainGrid.Items.IndexOf(mainGrid.SelectedItem));

Dispatcher.BeginInvoke(new Action(() => 
    mainGrid.ScrollIntoView(mainGrid.SelectedItem)));

Dispatcher.BeginInvoke(new Action(() => 
    mainGrid.BringIndexIntoView(mainGrid.Items.IndexOf(mainGrid.SelectedItem))));

All of the above methods simply scroll my grid a few pixels only and then stop. All four behave the same way. If I call all four together, it scrolls (a couple pixels * 4). Any ideas?

Non resizable RadPaneHeaders

Hi. I'am using 2010 Q3 WPF controls with Visual Studio 2010. I Have RadSplitContainer with RadPanes. I want RadPane Headers to be non resizable when application window width gets smaller then headers total width. I want to get same behavior as the Visual Studio tabs headers behavior. When application window width is smaller then tabitems headers total width most right Header is hiding and when application window width increasing tabitem header is again visible. Is it possible to do the same behavior for RadPane Headers. Also in Visual Studio selected Tab is set to first position (if it was not in first position and there is not enough space because of the window width decreasing)

Thank you,
Regards Armen

Window with RadDocking control behaves in a non-standard way in relation to the Windows task bar

I noticed that a window with a RadDocking control behaves in a strange fashion in relation to the Windows task bar:

Whereas every other window of whatever application when dragged towards the task bar is behind it, a window with the RadDocking control - if it is activated - is above the task bar. If other windows are behind the active window with a RadDockingControl, they get placed above the task bar as well, but only in this case.

How do I fix this behavior so that a window with a RadDocking control is always behind the Windows task bar like every other standard window?

I use Windows 7.

Pane with PRISM region

Hi,

i have the following scenario (RadDocking with three panes and on the third pane is a PRISM region) :

<Grid HorizontalAlignment="Stretch" VerticalAlignment="Stretch">

<Telerik:RadDocking Name="Docking" UI:PaRadDockingExtensions.IsEnabled="True"

ItemContainerStyle="{DynamicResource PaNewRadDockPaneStyle}" AllowUnsafeMode="True" >

<Telerik:RadDocking.DocumentHost >

<Telerik:RadSplitContainer Orientation="Vertical">

<Telerik:RadPaneGroup Name="MapGroup">

<Telerik:RadPane Header="Pane1" Telerik:RadDocking.SerializationTag="C1">

<AlapModul:CikkInputView DataContext="{Binding}" />

</Telerik:RadPane>

<Telerik:RadPane Header="Pane2" Telerik:RadDocking.SerializationTag="C2" >

<AlapModul:CikkKiegeszitoInputView DataContext="{Binding}" />

</Telerik:RadPane>

<Telerik:RadPane Header="Pane3" Telerik:RadDocking.SerializationTag="C3" >

<ContentControl cal:RegionManager.RegionName="{Binding MERegionName}" DataContext="{Binding}"/>

</Telerik:RadPane>

</Telerik:RadPaneGroup>

</Telerik:RadSplitContainer>

</Telerik:RadDocking.DocumentHost>

</Telerik:RadDocking>

At runtime, when I begin drag the pane with the PRISM region, I got the following error:

An exception occurred while creating a region with name 'cc4ebccf-36cf-410c-b390-318f6e905d1b'. The exception was: System.InvalidOperationException: ContentControl's Content property is not empty.
    This control is being associated with a region, but the control is already bound to something else.
    If you did not explicitly set the control's Content property,
    this exception may be caused by a change in the value of the inherited RegionManager attached property.

Any idea what I do wrong?

Thanks,
