While using RedGate ANTS Performance Profiler, I get to a point in my application where I click on a RadButton.  Through the event handlers that subsequently get fired, I eventually get the following error:

System.Windows.Markup.XamlParseException: The type initializer for 'Telerik.Windows.Controls.RichTextBoxUI.RadRichTextBoxRibbonUI' threw an exception. ---> System.Security.VerificationException: Operation could destabilize the runtime.

This only occurs when I'm running the profiler and so far, only in this one place.  The view that it's trying to initialize doesn't explicitly use the RadRichTextBoxRibbonUI.  It only uses RadWrapPanels and a RadComboBox.

Seeing how this doesn't happen during normal execution, it's hard to identify a cause within my implementation.  Also, not knowing the intrinsic behavior of how the performance profiler sets stuff up, I don't know what the difference would be.  

Any thoughts?

Hi

If I add page numbers into the header or footer, they show the correct page number for each page (as you'd expect).

If you then protect the document, they will all show the same page number.  And one of them usually shows some selection highlighting on it too.  Even if I set the permissions for the page number to Everyone... same problem!

Any fix or workaround for this?

How does one get the GridView to detect property validation attribute violations when they are specified in a buddy class?  For example, the property attributes in the buddy class below are not respected by the GridView.  I.e., the grid doesn't indicate a validation error for and it permits entry of a part number that doesn't match the regex. By contrast, the GridView does respect the IValidatableObject.Validate method.  I've tried making the PartMetadata class public; but it still didn't validate.

Any ideas?  thanks!

Hi,

I have a gridview, and its itemsSource is bound to an ObservableCollection in the ViewModel, and the isBusy property is also bound to a property there. Initially the collection is empty. In the constructor of the ViewModel I initiate a new thread which does the data collection from the DB. When the thread starts, it sets the isBusy property to true and triggers a notification, so the grid displays the loading animation. When the data is collected, the grid is notified again, and it displays the data. At the beginning the query which collected the data ran for 10+ seconds, and everything worked fine. But the query was optimized, so now it runs for less then a second, and here comes my problem: at startup for some reason I have no data displayed in the grid. The pager displays correct data, everything is fine except there is nothing in the grid. If I go to the second page, the data appears, and from that point everything works fine again.

I guess that my problem is related with the worker thread I create and the PropertyChanged notification, but I have no idea how to make it work. One more detail: if I put a Thread.Sleep(1000) before the PropertyChanged notification, everything works as expected. But this is not a nice way to solve the problem.

Any ideas how to make it work?

Thanks,

Hi,

In RadScheduleView I wan to show the start and end time for the particular slot when mouse hovering on that slot. For achieving this, I
used the Mouseoverhighlightstyle. The code looks like this.

But it is not working....

ANY HELP.......

In My Project I need to Emabad many types of documents Like word ,excel,pdf ,picturs ..
there is a way to use teleik control to support this kind of solution.

I'm currently evaluating the RadDocking classes for a client - so I'm pretty new to the telerik stuff. Bear with me...

I've made a super-simple example with a couple of portfolios in a tabbed container:

What I'd like to do is reorder the tabs in the DocumentHost using drag-and-drop (like you can reorder tabs in your Internet Explorer 8 or Visual Studio 2010).

Does anyone know how to do this?

Hi,
I am setting the list box orientation to Horizontal with this XAML
 
                           <telerik:RadListBox.ItemsPanel>
                                <ItemsPanelTemplate>
                                    <VirtualizingStackPanel Orientation="Horizontal" />
                                </ItemsPanelTemplate>
                            </telerik:RadListBox.ItemsPanel>

and it's work fine but  i did not find how can i set the Horizontal ScrollBar Visibility

e.g.
  VerticalScrollBarVisibility="Auto" or HorizontalScrollBarVisibility="Auto" 


Thanks

Hi,

I have a RadGridView in my WPF v2011.3.116.40 application. This RadGridView has 6 columns.

Let's say that the last column extends beyond the RadGridView and I have not selected any cell in this RadGridView, so only part of those cells are visible.
When I click on a cell of this column, my horizontal scrollbar is moved so as to show the entire contents of the cell.

I would like to override this behaviour so that selecting a cell does not shift my horizontal scrollbar, except if the keyboard navigation keys are used to select a cell that is not visible at all.
I have not found a property of RadGridView that would implement this.

I hope my question is clear.

Thanks.

I'm using TwoWay binding on the SelectedItem property of the RadTreeListView control to sync my view and view model:  

SelectedItem="{Binding SelectedItem,Mode=TwoWay}" SelectionMode="Single"

It appears that the selected item brush color is not applied to the SelectedItem in this scenario:

Load control
Expand tree
Collapse tree
Set SelectedItem in view mode

In other scenarios, the selected item brush color is applied correctly.
