Hello,

I'm using RadCartesianChart with multiple series (each series contains thousand of data points). I enabled ChartTrackBallBehavior (

<telerik:ChartTrackBallBehavior ShowIntersectionPoints="False" ShowTrackInfo="True" SnapMode="AllClosePoints" TrackInfoUpdated="ChartTrackBallBehavior_OnTrackInfoUpdated"/>) . Now in TrackInfoUpdated a would like find closest data point. Unfortunately property Context.ClosestDataPoint of TrackBallInfoEventArgs always returns first datapoint of first series regardless which datapoint is really closest. How can I detect really closest data point?

Thanks for help.

RadPaneGroupRegionAdapter not working for Prism 4 November release

Hi,

I downloaded the source project with the RadPaneGroupRegionAdapter from here:

Using the RadDocking control with Prism

And I updated the reference and the bootstrapper to use the Prism 4 November release. Then I found it's no longer working.

There is no exceptions, just that the RadPane's are not showing.

Following are the only code change I made, (all inside bootstrapper):

using System;

using System.Net;

using System.Windows;

using System.Windows.Controls;

using System.Windows.Documents;

using System.Windows.Ink;

using System.Windows.Input;

using System.Windows.Media;

using System.Windows.Media.Animation;

using System.Windows.Shapes;

using Telerik.Windows.Controls;

using Microsoft.Practices.Prism.UnityExtensions;

using Microsoft.Practices.Prism.Regions;

using Microsoft.Practices.Prism.Modularity;

using Microsoft.Practices.Unity;

namespace RadDockingAndPRISM

{

public class Bootstrapper : UnityBootstrapper

{

protected override RegionAdapterMappings ConfigureRegionAdapterMappings()

{

var mappings = base.ConfigureRegionAdapterMappings();

mappings.RegisterMapping(typeof(RadPaneGroup), ((IUnityContainer)Container).Resolve<RadPaneGroupRegionAdapter>());

return mappings;

}

protected override DependencyObject CreateShell()

{

Shell shell = Container.Resolve<Shell>();

#if SILVERLIGHT

App.Current.RootVisual = shell;

#else

shell.Show();

#endif

return shell;

}

//protected override IModuleCatalog GetModuleCatalog()

//{

// var catalog = new ModuleCatalog();

// catalog.AddModule(typeof(ModuleA.ModuleA));

// catalog.AddModule(typeof(ModuleB.ModuleB));

// return catalog;

//}

protected override void ConfigureModuleCatalog()

{

base.ConfigureModuleCatalog();

((ModuleCatalog)ModuleCatalog).AddModule(typeof(ModuleA.ModuleA));

((ModuleCatalog)ModuleCatalog).AddModule(typeof(ModuleB.ModuleB));

}

Could you please help? Thanks!

Line Series mouse events when render mode is set to Light

Is there any way to subscribe to mouse events on a line series that is rendered in light mode? I tried testing some mouse events (enter, move, leave, mousedown) and they work when the line series is set to full mode, but not when it's light. I've been wondering if this is because of a lack of a clickable area in the extremely thinly rendered line series or if it's because of the mechanism in which a light series is rendered.

If there's documentation about what is available/unavailable when the series is rendered in Light Mode, could I be linked to it? Thank you!

RichTextBox MailMerge changes

I am facing an interesting problem with the RadRichTextBox. I assemble a document converting documents to fragments, and the documents that contain the fragments can contain merge fields. There will only be a single merge. The assembled document is displayed in a RadRichTextBox that I want to display with the merged values, meaning that I display this RadRichTextBox with "Document.ChangeAllFieldsDisplayMode(FieldDisplayMode.Result)". A second RadRichTextBox displays the document used for assembly, depending on the fragment selected.

Seems like things are working well with the merge fields except that the values can change, and the changes are not reflected in the assembled document. When I change the ChangeAllFieldsDisplayMode back and forth the changed will be displayed. Any good way to fix this problem?

Header Row in Table Design tab

I noticed that there was a Header Row option available (ToggleTableLookFirstRowOptionCommand) but it does not seem to have any effect. Is there something I am doing wrong?

Suppressing the "Drawing" of a series every time the databound series changes

Hi,

I have a RadChart containing a SeriesMapping whose ItemSource is data bound to a collection. This collection is also bound to a grid so the contents can be altered. This works great, however whenever I add a new item to the collection the series on the chart appears to redraw, ie it draws from left to right.

I fully understand that the collection has changed so this needs to be reflected in the chart, but the drawing it does is problematic, is there any way to control how this renders? Ideally I don't want to see it being drawn in real time, only once it has been fully rendered. I know this might mean a slight delay but would be much more desirable from a user perspective.

Thanks

Application menu alignment

Hello, I'm using a custom RibbonView style derived from the Windows 8 theme.
When I press the application menu button (HorizontalOffset="0" for DropDownPopup), the popup menu appears as in the attached image "1" or "2" depending on different computers.
To correct this, when I set HorizontalOffset to the width of the popup menu, I obviously get the results as in the image "2" or "3".
I have tested several properties to control the popup behavior, but nothing helped and I have no idea why this popup behavior appears different for some specific desktop settings.
Can this be fixed? Thank you!
