Hi there,

I just performed an upgrade from 2014 Q4 to 2015 Q1 and have run into an unexpected issue.  I have been using Panel Bar Item injection via the prism framework to place panel bar items for each of my modules under their respective headers.

In my shell, the regions are laid out as follows:

<telerik:RadPanelBar
                DockPanel.Dock="Left"
                Width="200"
                regions:RegionManager.RegionName="NavPanelRegion"
                Background="LightBlue">
                <telerik:RadPanelBarItem
                    regions:RegionManager.RegionName="NavPanelHomeRegion"
                    Header="Home">
                </telerik:RadPanelBarItem>
                <telerik:RadPanelBarItem
                    regions:RegionManager.RegionName="NavPanelToolsRegion"
                    Header="Tools">
                </telerik:RadPanelBarItem>
                <telerik:RadPanelBarItem
                    regions:RegionManager.RegionName="NavPanelMaintenanceRegion"
                    Header="Maintenance">
                </telerik:RadPanelBarItem>
                <telerik:RadPanelBarItem
                    regions:RegionManager.RegionName="NavPanelReportingRegion"
                    Header="Reporting">
                </telerik:RadPanelBarItem>
</telerik:RadPanelBar>

Then each of the modules has one to many panel bar items defined:

<telerik:RadPanelBarItem  x:Class="Modules.Dashboard.Views.DashboardPanelItemView"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
             xmlns:regions="http://www.codeplex.com/CompositeWPF"
             xmlns:vm="clr-namespace:Modules.Dashboard.ViewModels"
             Header="Homepage">
    <telerik:RadPanelBarItem.Resources>
        <vm:DashboardCommandViewModel x:Key="DashboardCommandVm" />
    </telerik:RadPanelBarItem.Resources>
    <telerik:RadPanelBarItem.Command>
        <Binding Source="{StaticResource DashboardCommandVm}" Path="Home" />
    </telerik:RadPanelBarItem.Command>
</telerik:RadPanelBarItem>

And during module initalization, the following is called:

public void Initialize()
        {
            Container.RegisterType<Object, Views.DashboardView>("DashboardView");
            this._regionViewRegistry.RegisterViewWithRegion(RegionNames.Navigation.HomeNavigationPanelRegion, typeof(Views.DashboardPanelItemView));
            this._regionViewRegistry.RegisterViewWithRegion("ContentRegion", typeof(DashboardView));
        }

Prior to the update, this worked just fine and the panel bar items were injected under their respective parents.  Now, though, post-upgrade, it's no longer functioning.

Any thoughts?

I have a simple pane factory which basically looks like this:

class PaneFactory : DockingPanesFactory
{
    protected override void AddPane(RadDocking radDocking, RadPane pane)
    {
        //Docking is UserControl, which contains RadDocking
        var docking = radDocking.ParentOfType<Docking>();
        var settings = pane.Tag as PaneSettings;
 
        if (settings.ScreenPosition == ScreenPosition.Left)
        {
            //LeftPaneGroup is pane group declared in xaml (docked to left side)
            docking.LeftPaneGroup.AddItem(pane, DockPosition.Center);
        }
        else
        {
            //DocumentPaneGroup is document host declared in xaml
            docking.DocumentPaneGroup.AddItem(pane, DockPosition.Center);
        }
    }
}

So there are two options: pane is either initially docked to the left or to the document host. If it is docked to document host - PaneStateChange
event is fired, but if it is docked to the left - there is no event. Is this a bug or an expected behaviour? Looks really inconsistent to me. Is there a way to force PaneStateChange event to always fire, when new pane is added?

Hi,
Connectors of some items are generated dynamically in run-time, so I tried to bind Connectors using Extension. Drag-drop process are definitely working good, but when I bind all diagram,before calling extension method, it throws exception "XmlParseException - The default connectors cannot be removed because connections are attached to it.".

Thanks in advance.

    public class ConnectorExtension
    {
 
        public static readonly DependencyProperty ConnectorsProperty =
            DependencyProperty.RegisterAttached("Connectors", typeof(List<ConnectorModel>), typeof(ConnectorExtension), new UIPropertyMetadata(null, new PropertyChangedCallback(ConnectorsChanged)));
 
 
 
        public static void SetConnectors(UIElement element, List<ConnectorModel> value)
        {
            element.SetValue(ConnectorsProperty, value);
        }
        public static List<ConnectorModel> GetConnectors(UIElement element)
        {
            return (List<ConnectorModel>)element.GetValue(ConnectorsProperty);
        }
 
 
        public static void ConnectorsChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
        {
            var connectors = e.NewValue as List<ConnectorModel>;
            var shape = d as RadDiagramShapeBase;
            if (shape != null )
            {
                if (connectors != null)
                {
                    shape.UseDefaultConnectors = false;
                    shape.Connectors.Clear();
                    connectors.ForEach(connector => shape.Connectors.Add(new RadDiagramConnector() { Offset = connector.Offset, Name = connector.Name, Tag=connector.Name }));
                }
                else
                {
                    shape.UseDefaultConnectors = false;
                    shape.Connectors.Clear();
                }
            }
        }
      
    }
}

<Style x:Key="DynamicConnectorStyle" TargetType="telerik:RadDiagramShape">
    <Setter Property="Position" Value="{Binding Position, Mode=TwoWay}"/>
    <Setter Property="IsSelected" Value="{Binding IsSelected}" />
    <Setter Property="Height" Value="{Binding Height}" />

    <Setter Property="ContentTemplate" Value="{Binding Path=TemplateKey,Converter={StaticResource DataTemplateSelector}}" />

I have a rad ribbon view which has been configured to IsMinimizable to False, however double clicking on a ribbontab results in the ribbon view being set to minimized. Is this a known bug? Is there any known workarounds?

At present my only solution is setting isminimized to false in the minimizedchanged event, this still results in a small flicker of the panel.

Hi, 

I am triying to set background under entire row by items in a RadTreeView, but I don´t have expected result.

This is my actual result:

Hi Everyone,

We are testing RadTreeView application  with CUIT. Whenever we test header less RadTreeView has single column with Microsoft Coded UI.is giving same name property value for all rows, but in wpf , CUIT name property value is row content.

Can you help me here to get unique names(row content) for rows.
for more details please see the attached image.

Source:
===================
  <Grid x:Name="LayoutRoot" >
        <telerik:RadTreeListView x:Name="radTreeListView"
                            AutoGenerateColumns="False" ShowColumnHeaders="False">
            <telerik:RadTreeListView.ChildTableDefinitions>
                <telerik:TreeListViewTableDefinition ItemsSource="{Binding Items}" />
            </telerik:RadTreeListView.ChildTableDefinitions>
            <telerik:RadTreeListView.Columns>
                <telerik:GridViewDataColumn DataMemberBinding="{Binding Name}" AutomationProperties.Name="{Binding Name}"  AutomationProperties.AutomationId="{Binding Name}"/>               
            </telerik:RadTreeListView.Columns>
        </telerik:RadTreeListView>

Hello,

I've been trying to solve the riddle of setting my chart's LegendLabel items. What I have is a query that provides a result set from a database. Two of the items are mapped (see code below) and I'm trying to figure out how to get the LegendLabel to display the appropriate info.

Here is my code segment:

            radChart.DefaultView.ChartLegend.Header = "Series";
                
            radChart.DefaultView.ChartArea.DataSeries.Clear();
            radChart.SeriesMappings.Clear();
            radChart.ItemsSource = this.getChartData();
            radChart.DefaultView.ChartTitle.Content = _chartTitle;
            //radChart.DefaultSeriesDefinition.LegendDisplayMode = LegendDisplayMode.DataPointLabel;
            //radChart.DefaultView.ChartLegend.Items.Add(new ItemMapping("Series"));
            radChart.DefaultView.ChartLegend.UseAutoGeneratedItems = false;

            SeriesMapping seriesMapping = new SeriesMapping();
            //seriesMapping.LegendLabel = "Series";
            seriesMapping.SeriesDefinition = new BarSeriesDefinition();
            //seriesMapping.ItemMappings.Add(new ItemMapping("Series", DataPointMember.LegendLabel));
            seriesMapping.ItemMappings.Add(new ItemMapping("Scenario_name", DataPointMember.XCategory));
            seriesMapping.ItemMappings.Add(new ItemMapping("Overall_RC0_Pct", DataPointMember.YValue)); 
            radChart.SeriesMappings.Add(seriesMapping);


I scoured numerous simliar posts to my query but haven't been successful yet. I was a bit confused as to what property I needed but as you can see I've set my Legend Header to the word "Series"

I want the items below to display the actual content of the underlying result set that comes from a column named "Series". So what the only time I see anything generated is when I set the "UseAutoGeneratedItems" to true and all I see is 'Series 0'

I tried mapping to the LegendLabel but I am not sure if that is correct or if I need to map to the ChartLegend.Items? If that is how I need to go what is the actual syntax to do that. 

Thanks again for your help!

It is really easy to implement MergeField functionality. However sometimes I don't want the user to see the property-names of my MailMerge-Class but use different names, especially since properties don't allow spaces. Is it possible to use something like the "Display" annotation to have "speaking field names" instead of class properties? E. g. something like this:

public class MailMessageInfo
{
    [Display(Name="sender, first name")]
    public string SenderFirstName { get; set; }
 
    [Display(Name = "sender, last name")]
    public string SenderLastName { get; set; }
}

and RichTextBox takes the "Display" annotation to display the MergeField?
