Adding more ContextMenuItems to RadMaskedContextMenu

I have need for adding more context menues to a RadMasketContextMenu - but I want to keep the three original (copy, cut, paste).

<Controls:RadMaskedTextBox x:Name="contactPhone" Style="{StaticResource RadMaskedTextBoxStyle}"
                TabIndex="12" Value="{Binding Entity.Phonenumber, NotifyOnSourceUpdated=True, Mode=TwoWay}"
                MaskType="None">
            <telerik:RadContextMenu.ContextMenu>
                <telerik:RadContextMenu>
                    <telerik:RadMenuItem Header="Hello"/>
                    </telerik:RadContextMenu>
                </telerik:RadContextMenu.ContextMenu>
        </Controls:RadMaskedTextBox>

This does not work - I do not get the Hello-context menu added. How do I do this?

Thanks!

The only difference between these two objects is Property "Description", which wether included in grdiview or not.

Flip Axis?

I suspect the answer is no but is there a way to flip the axis of the chart so that the column headers render down the left hand side instead of across the top?

Thanks,

Scrollbar fires DragInitialized

Hello Telerik,

I am using a RadTreeView like this:

<telerik:RadTreeView IsVirtualizing="True" SelectionMode="Multiple" telerik:DragDropManager.AllowDrag="True" telerik:DragDropManager.AllowCapturedDrag="True">

My problem is, when a vertical scrollbar appears and I move the scroll thumb down with the mouse, it fires a DragInitialize event and thus won't scroll the tree,
How can I prevent the DragInitialize, when I am actually on the scrollbar?

Here is the call stack:
TreeMitTelerik.exe!TreeMitTelerik.MainWindow.OnDragInitialize(object sender, Telerik.Windows.DragDrop.DragInitializeEventArgs args) Telerik.Windows.Controls.dll!Telerik.Windows.DragDrop.DragInitializeEventArgs.InvokeEventHandler(System.Delegate genericHandler, object genericTarget)
Telerik.Windows.Controls.dll!Telerik.Windows.DragDrop.DragInitializer.StartDrag()
Telerik.Windows.Controls.dll!Telerik.Windows.DragDrop.DragInitializer.StartDragPrivate(System.Windows.UIElement sender)
Telerik.Windows.Controls.dll!Telerik.Windows.DragDrop.DragInitializer.DragSourceOnMouseMove(object sender, System.Windows.Input.MouseEventArgs e)

New to WPF and problem with Style in Resource Dictionary

I've been working with silverlight mostly, but I'm converting an app to WPF. I'm using a mystyle.xaml resource dictionary and it's compiling ok, but I get this error message when I debug the program, 'Failed to create a 'TargetType' from the text 'telerik:RadDatePicker'. ...
The initelisense says it's ok and it compiles. The project it configured with the dropdown Telerik->RadControls for WPF ->Configure Project and I have all the references.

Also, I don't see the Telerik controls in the toolbar to the left. Even when I try to 'Launch Toolbox Configurator', it's doesn't do anything. This doesn't bother me since I usually don't use the toolbox, but it may be related. Maybe I'm missing something on my install

export/extract image bytes of each page

Hi all,

Im trying to discover the features of the RadPDFViewer control and I really want to either save each page to a JPG/PNG/etc file or perhaps just 'get' the bytes/memory stream of each page that I can use in various places in my WPF app.

I saw the filters API, but I cannot find examples or code samples on this API, can what I desire be achieved?

Thanks a lot
Mark

Exception - first letter caps

I have a masked text input box that I am using in the edit template of a data form. I have been getting odd exceptions when I try to update the text in this box. I finally figured out that if I go to the textbox and start with a capital (i.e. shift+alpha key), I get the exception. If I start typing in the textbox with a lower case alpha character or click the mouse in the box again, I have no problem.

Here is the textbox definition along with the stackpanel for that item:

<StackPanel Orientation="Horizontal" Grid.Row="2" Grid.Column="1" Margin="0,0,0,5">

<TextBlock Text="Description" Margin="0,0,0,0" VerticalAlignment="Center" Width="{StaticResource LabelWidth}" Style="{StaticResource LabelBoldStyle}" />

<telerikInput:RadMaskedTextInput x:Name="txtDescription" Mask="" Width="{StaticResource LargeLabelWidth}"

SpinMode="None" IsClearButtonVisible="False" SelectionOnFocus="SelectAll"

TextMode="PlainText" InputBehavior="Replace" SectionsNavigationMode="None"

Value="{Binding Description, Mode=TwoWay}" UpdateValueEvent="LostFocus"

>

</telerikInput:RadMaskedTextInput>

</StackPanel>

Here is the exception that I get:

System.IndexOutOfRangeException was unhandled by user code

Message=Index was outside the bounds of the array.
