Display selected value in ComboBox with Checkbox

Hi,
I am creating a combobox in which I have placed check boxes which allows me multiple selection. I tried it in two ways:

1. I used a collection of objects of entities defined by me.
2. Created a datatable and then assigned it to the combobox.

In both the approaches I have same problem of showing the seleced items with check box selected in the combobox.

I have used follwoing code, which is showing me values correctly in the combobox but the problem occures when I want to show the selected item's check box selected. Can anyone suggest me a solution for this Or if you have any other better idea to implement the multiple selecte combobox then I will be greatful to you.
i have used :

<ComboBox Name="cboBox1"
                              Style="{StaticResource ComboBox}" ItemsSource="{Binding}">
                        <ComboBox.ItemTemplate>
                            <DataTemplate>
                                <StackPanel Orientation="Horizontal" VerticalAlignment="Center">
                                    <CheckBox Margin="3" Name="chkInsideCboBox1"
                                              DataContext="{Binding ElementName=BusinessEntityName, Path=BusinessEntityId}"
                                              IsChecked="{Binding Path=Default}"  Style="{StaticResource CheckBoxFilter}"></CheckBox>
                                    <TextBlock Text="{Binding Path=BusinessEntityNameField}" ></TextBlock>
                                </StackPanel>
                            </DataTemplate>
                        </ComboBox.ItemTemplate>
                    </ComboBox>

Thanks in advance

RenderTransforms?

Hi guys,

Do you take apply RenderTransforms to the transition?
For example:

<telerik:RadTransitionControl ClipToBounds="False" Content="[Bound to data]" Margin="30" Duration="0:0:0.2"
                                                                      VerticalContentAlignment="Center" HorizontalContentAlignment="Center">
                                            <telerik:RadTransitionControl.Transition>
                                                <telerik:MotionBlurredZoomTransition />
                                            </telerik:RadTransitionControl.Transition>
                                            <telerik:RadTransitionControl.RenderTransform>
                                                <TranslateTransform Y="Some value, i.e. -200" />
                                            </telerik:RadTransitionControl.RenderTransform>
                                        </telerik:RadTransitionControl>

This transition will position the Content disappearance at center instead at TranslateTransform-ed location.

PrintExtension crashes on element.Arrrange

Hello,

We are using the PrintExtensions class as mentioned in Vlad's post 9 months ago.

Our application is a WinForms app that has an ElementHost we use to load the control. It has started crashing on the following line:

element.Arrange(new Rect(new Point(0, 0), element.DesiredSize));

It doesn't even throw an exception in Debug mode (F5), it just crashes to desktop. We stepped through the code to identify where the exception occurs and found it on that line. The only other thing I see is some first chance exceptions in the Debug Output window like so right after the exception occurs:

Step into: Stepping over non-user code 'System.Windows.Point.Point'

A first chance exception of type 'System.InvalidOperationException' occurred in PresentationFramework.dll

Step into: Stepping over non-user code 'System.Windows.Threading.ExceptionWrapper.TryCatchWhen'

A first chance exception of type 'System.Reflection.TargetInvocationException' occurred in mscorlib.dll

Step into: Stepping over non-user code 'System.Windows.RoutedEventArgs.InvokeEventHandler'

Step into: Stepping over non-user code 'System.Windows.RoutedEventArgs.InvokeHandler'

Step into: Stepping over non-user code 'System.Windows.UIElement.RaiseEventImpl'

Step into: Stepping over non-user code 'System.Windows.RoutedEventArgs.InvokeHandler'

Step into: Stepping over non-user code 'System.Windows.UIElement.ReRaiseEventAs'

Step into: Stepping over non-user code 'System.Windows.RoutedEventArgs.InvokeHandler'

Step into: Stepping over non-user code 'System.Windows.UIElement.RaiseEventImpl'

Step into: Stepping over non-user code 'System.Windows.UIElement.RaiseEvent'

Step into: Stepping over non-user code 'System.Windows.Threading.Dispatcher.InvokeImpl'

Step into: Stepping over non-user code 'System.Windows.Forms.Application.ComponentManager.System.Windows.Forms.UnsafeNativeMethods.IMsoComponentManager.FPushMessageLoop'

Step into: Stepping over non-user code 'System.Windows.Forms.Application.ThreadContext.RunMessageLoopInner'

Step into: Stepping over non-user code 'SchedApp.SchedAppFrame.Dispose'

Step into: Stepping over non-user code 'System.ComponentModel.Component.Dispose'

Step into: Stepping over non-user code 'System.Windows.Forms.ApplicationContext.Dispose'

Step into: Stepping over non-user code 'System.Windows.Forms.Application.ThreadContext.DisposeThreadWindows'

Step into: Stepping over non-user code 'System.Windows.Forms.Application.ThreadContext.Dispose'

I'm not quite sure where to look for more information. So the FrameworkElement coming into the FixedDocument is of type Telerik.Windows.Controls.RadGridView, is the Arrange method being overridden? How would I troubleshoot what looks like an exception in the System.Windows.Point.Point structure?

Switching to edit mode

I'm trying to come up with a good way to have a cell that can be clicked on to navigate to another window related to the entity chosen in the cell. Typical application navigation. The edit mode for the cell has a button on the far right which opens a pop up window that lets the user query for an instance and choose it. Thus the user is able to edit the relationships of the data. Nifty.

Problem is I'm trying to come up with a good way to both allow the navigation in the cell, and switch to edit view. If I put a button in the CellTemplate, then the button is clicked on, instead of entering into edit mode. And there appears to be no further way to enter edit mode.

I was hoping the grid view had some way to show a control to enter edit mode, that was built in, so I wouldn't have to write it. If not, is there a RoutedCommand that can be raised from within the cell's template in order to enter edit mode? If so, I guess I could put in my own edit button.
