Hi,

I've got a little problem with grid virtualization. I've got this grid view:

    
            <telerik:RadGridView Name="mailRecipients" 
        
                                         Grid.Row="0" 
        
                                         ItemsSource="{Binding ElementName=departmentMailRecipients, Path=MailRecipients}"

                        </telerik:RadGridView.Columns> 
        
                    </telerik:RadGridView> 

            When user delete the content of the address column for the first row (The mandatory rules mark the cell as invalid) then scroll until the last row and rescroll on the first row, 

            the old content is displayed. Is there a way to leave the invalid content of a cell when user scroll down/up? (I know that wrap the 

            grid into a ScrollViewer avoid the virtualization but I prefer find another way, this bug occurs also on Grid with huge amount of data in my application)

Issue with multi-series Bar Chart

Hi,

I seem to have a problem with a multiple-series bar chart. I have a custom X-Axis, which works fine. The Y-Axis is simply a number of phone calls figure, so the auto-scale axis would be fine. However, the values do not seem to marry up with those in the bar series. The image below illustrates this (flickr link, not sure if you can embed pics on here) :

http://farm4.static.flickr.com/3325/3525153961_2d6272a1dc_o.jpg

As you can see, the rightmost green bar = 111, which seems to line up with the Y-axis - however, none of the others do.

The XAML for the chart is as follows (incomplete, the remainder is legend name, title etc):

                    <control:RadChart x:Name="skillBarChart"           
                            telerik:Theming.Theme="Office_Black"  >         
                                   <control:RadChart.DefaultView>         
                                     <chart:ChartDefaultView >         
                                        <chart:ChartDefaultView.ChartArea >         
                                            <chart:ChartArea    x:Name="BarChartArea"          
                                                                LegendName="CustomLegend"          
                                                                FontFamily="Arial" FontSize="18"          
                                                                Height="446.848" Width="985">         
                                                <chart:ChartArea.AxisX>         
                                                    <chart:AxisX    MajorGridLinesVisibility="Collapsed"         
                                                                    Title="Skill" />         
                                                </chart:ChartArea.AxisX>         
                                                <chart:ChartArea.AxisY>         
                                                    <chart:AxisY    MajorGridLinesVisibility="Collapsed"         
                                                                    MinorGridLinesVisibility="Hidden"          
                                                                    Title="Calls" AutoScale="True"          
                                                                    MinValue="0" MaxValue="500"/>         
                                                </chart:ChartArea.AxisY>         
                                                <chart:ChartArea.Background>         
                                                    <LinearGradientBrush    EndPoint="0.5,1" StartPoint="0.5,0">         
                                                            <GradientStop           Color="#FF000000" Offset="0"/>         
                                                            <GradientStop           Color="#FF63B2DE" Offset="1"/>         
                                                    </LinearGradientBrush>         
                                                </chart:ChartArea.Background>         
                                            </chart:ChartArea>         
                                        </chart:ChartDefaultView.ChartArea>         

I'm populating the chart as follows (again a snippet) :

                             
                                     
                                        foreach (string s in skillname)         
                                        {         
                                            DataPoint Idp = new DataPoint();         
                                            Idp.YValue = noOfInCalls[Array.IndexOf(skillname, s)];         
                                            Idp.XValue = Array.IndexOf(skillname, s);         
                                            series1.Add(Idp);         
                                                     
                     
                                            DataPoint Odp = new DataPoint();         
                                            Odp.YValue = noOfOutCalls[Array.IndexOf(skillname, s)];         
                                            Odp.XValue = Array.IndexOf(skillname, s);         
                                            series2.Add(Odp);         
                                        }         
                                skillBarChart.DefaultView.ChartArea.DataSeries.Add(series1);         
                                skillBarChart.DefaultView.ChartArea.DataSeries.Add(series2);         

I then reformat the X-Axis with specific values for the 'skillname' to which each Y value corresponds, but do not do anything with the Y-Axis. However, I still get the issue as shown in the image. The '120' marker in the image is also cut off by the chart title area which I cannot seem to resolve.

Any assistance gratefully received! Thanks!

Highlighting an item on a chart

I have a WPF application with a Line chart.

I have a bunch of things that I cannot figure out how to do...
(1) When I user selects a particular value (in another control), which can be used to identify a particular data point in my chart, I want to be able to "highlight" that point on my chart. Is it possible to do that?
(2) Is it possible to make the circle which represents each data item bigger?
(3) When I add more data to the dataseries, the distance between two points on the X Axis keeps shrinking. Is it possible to keep that distance constant and scroll horizontally instead?

Any help with this is greatly appreciated.

Thanks,
-Sunandini

Needle is not animated when created in codebehind

Hi,

As you can see in the code below, I create a RadGauge dynamically in the codebehind. The problem is the needles are not animated if I code like in this way. Do I miss something in the code?

Needle ndl = new Needle();
ndl.Foreground = new SolidColorBrush(Colors.Yellow);
                        ndl.Background = new SolidColorBrush(Colors.Yellow);
                        RadGauge rg = new RadGauge();
                        rg.Height = 100;
                        rg.Width = 100;

                        ndl.IsAnimated = true;
                        ndl.Duration = new Duration(TimeSpan.FromSeconds(2));
                        rsStat.Min = 0;
                        double d = 0;
                        if (Double.TryParse(Value, out d))
                        {
                            rsStat.Label = new LabelProperties();
                            rsStat.Label.Location = ScaleObjectLocation.Inside;
                            rsStat.Label.FontSize = 8;
                            rsStat.Indicators.Add(ndl);
                            rsStat.Max = Math.Pow(10, Math.Ceiling(Math.Log10(d)));
                            ndl.Value = d;
                        }

RadCarouselPanel not scroll by clicking item

Hi,

I have used RadCarouselPanel with Button (Images used in the ex.) control as items as well appllied style to button. The problem is I am not getting scroll effect while clicking on button as demo shows whereas it shows as Carousel effect on the form.

<telerik:RadCarouselPanel x:Name="Panel1" VerticalAlignment="Center"
            IsOpacityEnabled="True" IsScalingEnabled="True" IsPathVisible="True"
            PathPadding="50" CanHorizontallyScroll="True" CanVerticallyScroll="True" >

Export

Do your chart controls have any export abilities? i.e. PDF, Excel, etc.

I read that charts could be saved as an image. Is it possible to save as a vector graphic?
