Problem with changing CategoryBrush value on the fly

Hello,

I have a class “Priority” which derives from the Category class and fires PropertyChanged when (New) CategoryBrush changes.

I assign the collection of Priority objects to the CategoriesSource property of the ScheduleView control.

The Edit window loads the list fine, but when the brush color of the Category aka Priority changes in the configuration window - the Edit window doesn’t reflect the change. Other controls bound to the CategoryBrush property of the same collection change the color but not the ScheduleView.

Can you see why?

Thank you.

Linear chart in circle

Hi,
I have just started my adventure with WPF. I have heard that it is dedicated for graphical applications. I'm interested in creating a control that handles linear chart and transform it into chart in a circle. I just wonder if there is some easy way to do that?

Thank you in advance for any reply.

input behavior

I was excited to get a new masking control, but this soon turned to disappointment. Our users have difficulty with these controls as they are not intuitive. They expect it to behave the same as if you were entering something into an Excel spreadsheet cell and I don't blame them. It's confusing to me as well. I've tried all kinds of variations of textmode, autofill properties, and InputBehavior to get a mask n5.2 to behave properly. Essentially I think it should behave just as a regular textbox while entering data and display according to the mask when viewing the data.

Upgrade Toolbox failed

Hi,

I'm trying to upgrade my Toolbox to the latest release (2011 Q1 SP1 - 2011.1.419.35) but I keep getting the following error:

Telerik VSExtensions: UpgradeToolbox: Access to registry key 'HKEY_LOCAL_MACHINE\Software\Microsoft\VisualStudio\9.0\Packages\{2c298b35-07da-45f1-96a3-be55d91c8d7a}\Toolbox' is denied. (Toolbox upgrade failed)

I installed the update via the update tool and all worked fine. Then I accidently selected to roll back the Toolbox to the previous version. Now I can't get the latest toolbox to show.

I'm using VS2008. Does anyone know how I can clear the toolbox and get the newer version to show up again? I've tried re-installing the latest release MSI but it hasn't done the trick.

Thank you for your time,

Rob

Cascading Combobox in a Grid

I have a grid with note types and note subtypes where the ID's for the note subtypes are not unique across all note types, just for the note type they are related to. Each NoteTpye object has a NoteSubTypes collection property.

Basically they work like below [id]-[value]

1-NoteType1
1-NoteSubType11
2-NoteSubType12
2-NoteType1
1-NoteSubType21
2-NoteSubType22

Because of this when I need to bind the items source of the NoteSubType column to NoteType columns selected NoteType.NoteSubTypes property. Here's what I have so far:

	    <telerik:RadGridView ItemsSource="{Binding Path=NotesList}" AutoGenerateColumns="False">
                <telerik:RadGridView.Columns>
                    <telerik:GridViewDataColumn
                        Header="ID"
                        DataMemberBinding="{Binding Path=ID}" />
                    <telerik:GridViewComboBoxColumn
                        Header="NoteType"
                        UniqueName="NoteType"
                        ItemsSource="{Binding Path=NoteTypeList}"
                        DataMemberBinding="{Binding Path=NoteTypeID}"
                        SelectedValueMemberPath="ID"
                        DisplayMemberPath="Name">
                    </telerik:GridViewComboBoxColumn>
 
                    <telerik:GridViewComboBoxColumn
                        Header="NoteSubType"
                        ItemsSource="{???}"
                        DataMemberBinding="{Binding Path=NoteSubTypeID}"
                        SelectedValueMemberPath="ID"
                        DisplayMemberPath="Name">
                        
                    </telerik:GridViewComboBoxColumn>
                </telerik:RadGridView.Columns>
            </telerik:RadGridView>

I just need to get the NoteSubType ItemSource. I have a IValueConverter and IMultiConverter already created for this if we need them (from experimentations with other grids).

SimpleFiltering: Programmatic access to series visibility

Hi,

I'm looking for ideas/guidance on how I can achieve the following:

I'd like to save which series are visible/hidden on form unload and restore which series are visible/hidden on form load. For this, I'm wondering how I can access the various Series<<seriesname>>Visibility properties in ExampleViewModel (for example, SeriesEU27Visibility, SeriesEuroAreaVisibility, SeriesJapanVisibility, SeriesUSVisibility) so that they can be read on form unload and then set in form load. In addition to setting these properties on form load, I would like to update the form accordingly to display/hide the correponding series and check/uncheck the corresponding check box in the legend.

I'm fairly new to .NET (I've been coding in VBA instead for over 10 years), so the .NET concepts are new, but programming concepts are familiar to me (I know OO programming concepts from Java, but are new to .NET concepts like ViewModels). I'd really appreciate any ideas or guidance on how I can achieve this.

Many thanks in advance!

Kind regards,
Dave.

Save and load layout

I make a Docking class set with an overwritten behavior.
I save the layout elements.
I make simple heirs of the elements set for docking:

public class TSplitContainer : RadSplitContainer { }

public class TPaneGroup : RadPaneGroup { }

public class TPane : RadPane { }

The RadDocking class has special properties for getting child elements:

d = new TDocking();

//d.CurrentSaveLoadLayoutHelper = new TDefaultSaveLoadLayoutHelper(d);

d.GeneratedItemsFactory = new TDefaultGeneratedItemsFactory();

now I add a special method for creating child elements upon loading:

public class

TDocking: RadDocking

{

protected override void OnElementLoading(LayoutSerializationLoadingEventArgs args)

{

System.Windows.DependencyObject res = args.AffectedElement;

if (res == null)

{

string st = args.AffectedElementSerializationTag;

if (st == typeof(TDocking).Name)

args.SetAffectedElement(this);

if (st == typeof(TDocumentPane).Name)

args.SetAffectedElement(new TDocumentPane());

if (st == typeof(TPaneGroup).Name)

args.SetAffectedElement(GeneratedItemsFactory.CreatePaneGroup());

if (st == typeof(TSplitContainer).Name)

args.SetAffectedElement(GeneratedItemsFactory.CreateSplitContainer());

}

System.Diagnostics.Debug.WriteLine("OnElementLoading: serializationTag={0}; res={1}", args.AffectedElementSerializationTag, res);

base.OnElementLoading(args);

}

a class for generating child elements.

public class TDefaultGeneratedItemsFactory: DefaultGeneratedItemsFactory

{

public override Telerik.Windows.Controls.RadPaneGroup CreatePaneGroup()

{

return new TPaneGroup();

}

public override Telerik.Windows.Controls.RadSplitContainer CreateSplitContainer()

{

return new TSplitContainer();

}

public override ToolWindow CreateToolWindow()

{

return base.CreateToolWindow();

}

I make a test method for checking:

d = new TDocking();

//d.CurrentSaveLoadLayoutHelper = new TDefaultSaveLoadLayoutHelper(d);

d.GeneratedItemsFactory = new TDefaultGeneratedItemsFactory();

TSplitContainer sc = new TSplitContainer();

d.Items.Add(sc);

TDocking.SetSerializationTag(sc, "TSplitContainer");

sc.InitialPosition = Telerik.Windows.Controls.Docking.DockState.DockedRight;

TPaneGroup pg = new TPaneGroup();

TDocking.SetSerializationTag(pg, "TPaneGroup");

sc.Items.Add(pg);

TPane pane = new TPane();

TDocking.SetSerializationTag(pane, "TPane");

pg.Items.Add(pane);

d1.LoadLayout(xml);

and now upon calling the LoadLayout method we get the following exception:
   at Telerik.Windows.Controls.Docking.DockingLayoutFactory.GetElementByTypeName(String elementTypeName)
   at Telerik.Windows.Controls.Docking.DockingLayoutFactory.LoadSplitContainer(XmlReader reader)
   at Telerik.Windows.Controls.Docking.DockingLayoutFactory.LoadDocking(XmlReader reader)
   at Telerik.Windows.Controls.RadDocking.LoadLayout(Stream source, Boolean raiseEventsIfNoSerializationTag)
   at Telerik.Windows.Controls.RadDocking.LoadLayout(Stream source)
   at RadarSoft.Report.Wpf.Viewer.TDocking.LoadLayout(String source) in D:\Report\RadarSoft.Report.WPF.Viewer\Controls\TelerikDubles\TDocking.cs:line 39
   at RadarSoft.Report.QuickApp.MainWindow.btnResult_Click(Object sender, RoutedEventArgs e)

now what do we see in the reflector?

public DependencyObject LoadSplitItem(XmlReader reader)

{

if (reader.Name == "RadSplitContainer")

{

return this.LoadSplitContainer(reader);

}

if (reader.Name == "RadPaneGroup")

{

return this.LoadPaneGroup(reader);

}

return null;

}

So, why go into all this trouble of creating child elements, if they are loaded in the splitter like this:

and how am I to cure this now???

p.s. saved xml file:
<?xml version="1.0" encoding="utf-8"?><TDocking><SplitContainers><TSplitContainer SerializationTag="TSplitContainer" Dock="DockedRight" Width="240"><Items><TPaneGroup SerializationTag="TPaneGroup" SelectedIndex="0"><Items><TPane SerializationTag="TPane" IsDockable="True" /></Items></TPaneGroup></Items></TSplitContainer></SplitContainers></TDocking>

Hierachrchical Data

Hello!

I got a sample project from telerik team! (235440_loadrowdetails) for hierarchical datagrid.

public class MyViewModel : INotifyPropertyChanged

{

public event PropertyChangedEventHandler PropertyChanged;

private ObservableCollection<Club> clubs;

private ObservableCollection<Player> players;

In my project I get my data in a background thread. And every time when data changes, my grid should update. Can you post me an "update-Method" for the telerik datagrid?

At the moment, I tried to do the following in my backgroundworker:

this.Dispatcher.BeginInvoke(System.Windows.Threading.DispatcherPriority.Normal,

(UpdateGrid)delegate(List<OrderView> ocov)

{

this.orderGrid.ItemsSource = ov.DisplayOrders(ref ocov);

}, e.Result);

but this is not allowed.

Greetings
