Can RadChart normalize multiple y-axis data automatically

Hi,

I would have a line graph with multiple y-axis series, can radChart "normalize" the data so that both series start from the same point ?

e.g

I have stock prices for Apple and Microsoft . Date on X-Axis,Normalized Price on Y-Axis. The prices of each stock are obviously totally different - but I want to see the relative differences between the two stocks. So I want both stocks to start at e.g 100% and then each day the price change will be converted to a %change in price. By doing this you can compare the 2 stocks directly in terms of price change.

RadGridView culture when exporting

Hi everybody,

I am using telerik v 2.0.50727 for WPF (and i need to use this version, not any other one) and I got this "problem" when I try to export the items inside the RadGridView to Excel file: I need to export text which is in not US culture, with "á" and "ñ" for example. When I try to export it using the Export method from the RadGridView I get them changed.

I searched for information all along the forum, I tried everything I found:

Like...

public PageStart()

{

Thread.CurrentThread.CurrentCulture = new CultureInfo("es-ES");

Thread.CurrentThread.CurrentUICulture = new CultureInfo("es-ES");

InitializeComponent();

}

and then trying even samples in other posts, like the one below, from LINK with the result in the picture.

I would ask for help to you, Telerik Team, please tell me how to adapt the culture from the RadGridView and make it export correctly the words like " á-Á " and the " ñ-Ñ ".

Thank you in advance and kind regards.

Alvaro.

RadOutlookbarItem Commands

I'm building an app with Prism, MVVM and have a RadOutlookBar in a 'navigation region' and would like to change the 'content region' as RadOutlookBarItems are selected.
I would like to duplicate this type of functionality (from a menu item) in the RadOutlookBarItem

<telerik:RadMenuItem Header="New Account" Command="{Binding ShowView}" CommandParameter="NewAccount">

Any ideas on how to approach this?

Thanks,
John

FlipDuration not taken into account when using .NextPage method

It seems that the FlipDuration property of the RadBook control is only taken into account when the user has initiated a page turn.

When using the method .NextPage or setting the property .RightPageIndex the flip duration is not used. Is this by design?

Is there a way to slow down a page turn when using .NextPage or .RightPageIndex?

Thanks,

Jim

Chart Legend error

I upgraded my WPF controls to version 2011.2.712.35 to fix a problem with adding the Camera Extension to a Chart for zooming. When I did this I started getting a very odd error in a call to add a LegendItemMarkerShape to the Legend. The chart xaml looks like this:

<UserControl x:Class="ABC.APP.ProfileWpf.ChartControl"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
             mc:Ignorable="d"
             d:DesignHeight="300" d:DesignWidth="300" xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation">
    <Grid>
        <telerik:RadChart Margin="0" Name="mChartControl">
            <telerik:RadChart.DefaultSeriesDefinition>
                <telerik:Bar3DSeriesDefinition />
            </telerik:RadChart.DefaultSeriesDefinition>
  
            <telerik:RadChart.DefaultView>
                <telerik:ChartDefaultView>
                    <telerik:ChartDefaultView.ChartLegend>
                        <telerik:ChartLegend Name="legend" />
                    </telerik:ChartDefaultView.ChartLegend>
                    <telerik:ChartDefaultView.ChartArea>
                        <telerik:ChartArea LegendName="legend" DimensionMode="Strict3D">
                            <telerik:ChartArea.Extensions>
                                <telerik:CameraExtension />
                            </telerik:ChartArea.Extensions>
                        </telerik:ChartArea>
                    </telerik:ChartDefaultView.ChartArea>
                </telerik:ChartDefaultView>
            </telerik:RadChart.DefaultView>
        </telerik:RadChart>        
    </Grid>
 and the code where I pass the marker shape looks like this:

mChartControl.DefaultView.ChartArea.Legend.LegendItemMarkerShape = value;

I am using VS2010 and the weird thing here is if I let the code run without inspecting the object in the QuickWatch 
Dialog then it will exception with the error "Object reference not set to an instance of an object.".  If I 
go ahead and inspect the mChartControl object and drill all of the way down to the Lengend object the Legend 
object will show "+Legend{Telerik.Windows.Controls.Charting.ChartLegend Header: Items.Count:0}" that it does
exist and the code will run as it should without exception, but if I just do a hover over the string in the 
IDE the Legend oject will show a value of NULL and will exception.  Please let me know what is going on here
and what can be done to correct this.  Thanks for your help out there.

When writing customized property definitions, is it possible to mark properties as readonly? The workaround I have now is setting a control's IsEnabled property to false in the editortemplate
