I am having problem with getting the chart series to auto-update when data binding to nested collections is used. Following the example in the documentation, I created a list of ObservableCollections:


ChartData is just a simple class:


In the constructon of the class, after InitializeComponent() call, I am setting the itemSource as follows:


And finally here is the code snippet that adds a new series to the chart:


The problem I am having is that the chart control only shows data points that are already in the ObservableCollection at the time the window that has the chart is displayed; any data that gets added after the window is displayed do not get displayed in the chart at all.

What am I doing wrong? Any help would be greatly appreciated.
Thanks

Hello,

I Just upgraded to version 2010.1.422.35. Our screens are all contained inside of a ViewBox with Stretch="Fill". The Docking control works as expected but when the size changes the compass size doesn't change at all. I was wondering if you had any ideas on how i could change the compass size?

Thanks Much,

I`m using Rad TabControl Q3 sp1 and in VS 2008 I can`t open other tabitems than first one. I can`t see other items content. Even in the your example project.

I have a grid, where all the columns are of type: GridViewDataColumn.

One column (Modulation) in edit mode consists of a combo box and a button. Another grid is a TextBox.
The problem is that when I am changing the selection of the Combo box, and then move to another column (Fading Doppler), the "Modulation" column remains in edit, it doesn't loose focus.

Essentially what I have observed is that, since the fact that the another column is a TextBox, this problem happens. If the control is something else, the problem doesn't happen.

Here is the declaration of the columns:

                <!-- Modulation selection column -->
                <telerik:GridViewDataColumn Header="Modulation" Width="150" DataMemberBinding="{Binding Modulation, Mode=TwoWay}" TextAlignment="Center" >
                        <telerik:GridViewDataColumn.CellTemplate>
                            <DataTemplate>
                            <TextBlock Text="{Binding Modulation}" Foreground="{Binding Path, Converter={StaticResource colorConverter}}"/>
                            </DataTemplate>
                        </telerik:GridViewDataColumn.CellTemplate>
                        <telerik:GridViewDataColumn.CellEditTemplate >
                            <DataTemplate>
                                <StackPanel Orientation="Horizontal">
                                <ComboBox Loaded="Editor_Loaded" Width="100" Margin="5, 0, 0, 0" Foreground="{Binding Path, Converter={StaticResource colorConverter}}" Text="{Binding Modulation, Mode=TwoWay}" Background="White"  SelectionChanged="modulationChanged">
                                        <ComboBoxItem>Static</ComboBoxItem>
                                        <ComboBoxItem>Rayleigh</ComboBoxItem>
                                        <ComboBoxItem>Rician</ComboBoxItem>
                                </ComboBox>
                                <Button Content="More..." Foreground="{Binding Path, Converter={StaticResource colorConverter}}"/>
                                </StackPanel>
                            </DataTemplate>
                        </telerik:GridViewDataColumn.CellEditTemplate>
                    </telerik:GridViewDataColumn>

                <!-- Fading Doppler -->
                <telerik:GridViewDataColumn Width="110" DataMemberBinding="{Binding fDFreq, Mode=TwoWay}" >
                    <telerik:GridViewDataColumn.Header>
                        <TextBlock Text="Fading Doppler (Hz)" TextAlignment="Center" TextWrapping="Wrap" />
                    </telerik:GridViewDataColumn.Header>
                    <telerik:GridViewDataColumn.CellTemplate>
                        <DataTemplate>
                            <TextBox Text="{Binding fDFreq}" Foreground="{Binding Path, Converter={StaticResource colorConverter}}" IsReadOnly="True" IsEnabled="{Binding Modulation, Converter={StaticResource isModulationOtherThanStatic}}"/>
                        </DataTemplate>
                    </telerik:GridViewDataColumn.CellTemplate>
                    <telerik:GridViewDataColumn.CellEditTemplate>
                        <DataTemplate>
                            <TextBox Text="{Binding fDFreq, Mode=TwoWay}" Foreground="{Binding Path, Converter={StaticResource colorConverter}}" IsEnabled="{Binding Modulation, Converter={StaticResource isModulationOtherThanStatic}}"/>
                        </DataTemplate>
                    </telerik:GridViewDataColumn.CellEditTemplate>
                </telerik:GridViewDataColumn>

Hi,I'm trying to add Items to a RadCarouselPanel through Code, But I'm having trouble...

This is my code:

...
           
            <telerik:RadCarouselPanel Name="imgPicker"  ItemsMovementAnimationDuration="0:0:0.5"
                    ItemsPerPage="11" PathPadding="70,50,70,50" IsOpacityEnabled="True"
                    IsScalingEnabled="True" IsSkewAngleYEnabled="True" Height="100" MinHeight="100" >
                <telerik:RadCarouselPanel.Path>
                    <Path HorizontalAlignment="Center" VerticalAlignment="Center" Stretch="Fill" Data="M 0,300 C0,300 500,300 500,300 " />
                </telerik:RadCarouselPanel.Path>
                <telerik:RadCarouselPanel.SkewAngleYStops>
                    <telerik:PathStopCollection>
                        <telerik:PathStop PathFraction="0.15" Value="-15" />
                        <telerik:PathStop PathFraction="0.45" Value="-15" />
                        <telerik:PathStop PathFraction="0.5" Value="0" />
                        <telerik:PathStop PathFraction="0.55" Value="15" />
                        <telerik:PathStop PathFraction="0.85" Value="15" />
                    </telerik:PathStopCollection>
                </telerik:RadCarouselPanel.SkewAngleYStops>
                <telerik:RadCarouselPanel.ScaleStops>
                    <telerik:PathStopCollection>
                        <telerik:PathStop PathFraction="0.4" Value="1.0" />
                        <telerik:PathStop PathFraction="0.5" Value="1.5" />
                        <telerik:PathStop PathFraction="0.6" Value="1.0" />
                    </telerik:PathStopCollection>
                </telerik:RadCarouselPanel.ScaleStops>
                <telerik:RadCarouselPanel.OpacityStops>
                    <telerik:PathStopCollection>
                        <telerik:PathStop PathFraction="0.0" Value="0.0" />
                        <telerik:PathStop PathFraction="0.1" Value="1.0" />
                        <telerik:PathStop PathFraction="0.9" Value="1.0" />
                        <telerik:PathStop PathFraction="1.0" Value="0.0" />
                    </telerik:PathStopCollection>
                </telerik:RadCarouselPanel.OpacityStops>
            </telerik:RadCarouselPanel>           
...

And my CodeBehind:

public MainWindow ()
        {
            InitializeComponent();
           
            imageList = new List<BitmapImage>();

            BitmapImage bi = new BitmapImage();
            bi.BeginInit();
            bi.UriSource = new Uri(@"Imgs/OCR1.TIF", UriKind.RelativeOrAbsolute);
            bi.EndInit();
           
            imageList.Add(bi);

            bi = new BitmapImage();
            bi.BeginInit();
            bi.UriSource = new Uri(@"Imgs/OCR2.TIF", UriKind.RelativeOrAbsolute);
            bi.EndInit();

            imageList.Add(bi);

            bi = new BitmapImage();
            bi.BeginInit();
            bi.UriSource = new Uri(@"Imgs/OCR3.TIF", UriKind.RelativeOrAbsolute);
            bi.EndInit();

            imageList.Add(bi);

            imgPicker.DataContext = imageList;

         
        }

Is this the right way to do this?

My panel is not showing anything =/

Hi, i'm trying to do somethiing and didn't see anything like this on the samples, or useful events for this.

What do I want to do:

Let's say that I have a RadCarousel styled as a coverflow, with 4 images on this order A-B-C-D

I want to drag D to position 2, with the mouse, so the new order would be A-B-D-C

Any clue?

Thanks a lot!

When a user selected a current Item or an Item comes into view. How can I call an event to populate a gridview.

For example.. If a Item for John Doe becomes into view or is the selected Caroisel Item - I'd like to make a DB call to grab a dataset of his addresses.

How can I wire up an event to the selected Carousel Item and bind the dataset to the RadGridView.

Thanks again for all your help!!

I need to create a portal style WPF application much in the style of that shown in your My Portal demo at http://mono.telerik.com/Dock/Examples/MyPortal/DefaultCS.aspx

I created library with my custom theme for RadWindow, but after applying (using StyleManager) and click on header Close button application chashes.

I use this code for close button:

<telerik:RadButton x:Name="PART_CloseButton" Command="telerik:WindowCommands.Close" Style="{StaticResource WindowButtonStyle}">
                                        <Path Fill="{StaticResource WindowButtonIconFill}" Stroke="{StaticResource WindowButtonIconStroke}" Width="14" Height="14" Data="M1.5,3.5 L2.5,2.5 4.5,2.5 6.5,4.5 8.5,2.5 10.5,2.5 11.5,3.5 8.5,6.5 8.5,7.5 11.5,10.5 10.5,11.5 8.5,11.5 6.5,9.5 4.5,11.5 2.5,11.5 1.5,10.5 4.5,7.5 4.5,6.5 z" />
                                    </telerik:RadButton>

Also is use alternate of Command="telerik:WindowCommands.Close":
 
<Button.Command>
    <RoutedUICommand
    Text="Close" />
 </Button.Command>
than button not work.

Help me to resolve this problem.

Thanks
