Thanks in Advance.

I found a sample in your SDK "SelectedItemsBinding" part of your ComboBox.
Trying to understand the logic on using the ComboBox. This code seems very what I need but I would like to use "SelectedItem" not "SelectedItems". So I working on converting your sample code to signal selection. I have managed to adjust the MainWindows.xaml and kind of understand the List collection. But can't convert this to a signal selection. Yes there are other more simple ComboBox samples but this one interests me.
I changed all the references to "SelectedItems" to "SelectedItem" where I get these errors in VS: "Error CS1503 Argument 1: cannot convert from 'object' to 'System.Collections.IList'"
Can you help me make this work?
using System.Collections;using System.Collections.Specialized;using System.Windows;using System.Windows.Interactivity;using Telerik.Windows.Controls;namespace SelectedItemBinding{ public class SelectedItemBehavior : Behavior<RadComboBox> { private RadComboBox ComboBox { get { return this.AssociatedObject as RadComboBox; } } public INotifyCollectionChanged SelectedItem { get { return (INotifyCollectionChanged)this.GetValue(SelectedItemProperty); } set { this.SetValue(SelectedItemProperty, value); } } // Using a DependencyProperty as the backing store for SelectedItemProperty. This enables animation, styling, binding, etc... public static readonly DependencyProperty SelectedItemProperty = DependencyProperty.Register("SelectedItem", typeof(INotifyCollectionChanged), typeof(SelectedItemBehavior), new PropertyMetadata(OnSelectedItemPropertyChanged)); private static void OnSelectedItemPropertyChanged(DependencyObject target, DependencyPropertyChangedEventArgs args) { var collection = args.NewValue as INotifyCollectionChanged; if (collection != null) { ((SelectedItemBehavior)target).UpdateTransfer(args.NewValue); collection.CollectionChanged += ((SelectedItemBehavior)target).ContextSelectedItem_CollectionChanged; } } private void UpdateTransfer(object items) { Transfer(items as IList, this.ComboBox.SelectedItem); this.ComboBox.SelectionChanged += this.ComboSelectionChanged; } private void ContextSelectedItem_CollectionChanged(object sender, NotifyCollectionChangedEventArgs e) { this.UnsubscribeFromEvents(); Transfer(SelectedItem as IList, this.ComboBox.SelectedItem); this.SubscribeToEvents(); } private void ComboSelectionChanged(object sender, System.Windows.Controls.SelectionChangedEventArgs e) { if (this.ComboBox.ItemsSource != null) { this.UnsubscribeFromEvents(); Transfer(this.ComboBox.SelectedItem, SelectedItem as IList); this.SubscribeToEvents(); } } private void SubscribeToEvents() { this.ComboBox.SelectionChanged += this.ComboSelectionChanged; if (this.SelectedItem != null) { this.SelectedItem.CollectionChanged += this.ContextSelectedItem_CollectionChanged; } } private void UnsubscribeFromEvents() { this.ComboBox.SelectionChanged -= this.ComboSelectionChanged; if (this.SelectedItem != null) { this.SelectedItem.CollectionChanged -= this.ContextSelectedItem_CollectionChanged; } } public static void Transfer(IList source, IList target) { if (source == null || target == null) return; target.Clear(); foreach (var o in source) { target.Add(o); } } }} Hello.
In out project (MVVM, Microsoft prism) we use RadPaneGroup with RadPane. I need understand when user see RadPane. For this i use visibily and isSelected properties:
<telerik:RadPaneGroup>
<telerik:RadPane Header="{telerik:LocalizableResource Key=Neo_DailyIntroductionPlanFact}"
Name="ActivityDailyIntroductionFactTab"
telerik:RadDocking.SerializationTag="DailyIntroductionFact"
IsSelected="{Binding ActivityFactDataTabIsSelected, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
CanUserClose="False"
IsPinned="False"
Visibility="{Binding ActivityFactDataTabVisibility, Mode=OneWay, UpdateSourceTrigger=PropertyChanged}">
<ContentControl HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch"
regions:RegionManager.RegionName="{x:Static helpers:LocalRegionsNames.ActivityDailyIntroductionFactRegion}" />
</telerik:RadBusyIndicator>
</telerik:RadPane>
</telerik:RadPaneGroup>
When user view is closing, property IsSelected becomes equal 'true', even if it was equal before 'false'...why this happen?

Hi good afternoon:
I want to create something similar to winmerge for compare commited files using telerik. I need this control to be embedded in my app, for this reason I could not use JustAsembly. Does telerik have some control that I can use to get something like this?
Kind Regards,

I am having a problem getting my Telerik RadWindow to add modules to my module catalog. To get the RadWindow to load I had to override the Prism CreateShell method to return null.
protected override Window CreateShell() { //We must return null to override Window type.//return Container.Resolve<ShellWindow>();return null; }
I then handle all the initialization in the OnInitialized method.
protected override void OnInitialized() {
ShellWindow2 shellWindow = Container.Resolve<ShellWindow2>();
shellWindow.Show();
MainWindow = shellWindow.ParentOfType<Window>();
RegionManager.SetRegionManager(MainWindow, Container.Resolve<IRegionManager>());
RegionManager.UpdateRegions();
InitializeModules();
base.OnInitialized();
}
My problem is when I try to add modules to my Module Catalog I get an error : The region manager does not contain the MyRegion region.
protected override void ConfigureModuleCatalog(IModuleCatalog moduleCatalog) {
moduleCatalog.AddModule<SecurityModule>();
}
I think the problem is the module is trying to map to a region before the RegionManager is initialized in the OnInitialized method.
How can get the AddModule method to initialize after the RegionManager is set up?
Hi,
1) I need to place the HorizontalAxis Label above the chart. Is that possible?
2) I am trying to change the alignment of both Axis's titles: the HorizontalAxis Title to "left" and the VerticalAxis Title to "bottom" (near Chart's origin). How can I do that?
Could you show me a code example?
Thank you.

Hi,
I'm working with ChartView3D and Telerik UI for a project. I am using the XAML tags for the graph. I can build and compile the graph. During runtime, when I change the view angles of the graph and rotate, zoom it frequently the axes gets updated with the graph by a small delay. Sometime the axes get stuck. I have attached the screenshot for reference.
The code below is used to create the 3D graph,
<telerik:RadCartesianChart3D x:Name="E3DChart" Visibility="Collapsed">
<telerik:RadCartesianChart3D.XAxis>
<telerik:CategoricalAxis3D Title="Position">
<telerik:CategoricalAxis3D.TitleTemplate>
<DataTemplate>
<TextBlock Text="{Binding}" Foreground="White" Padding="3" FontSize="20" />
</DataTemplate>
</telerik:CategoricalAxis3D.TitleTemplate>
<telerik:CategoricalAxis3D.LabelStyle>
<Style TargetType="TextBlock">
<Setter Property="Foreground" Value="#FFD4D4D4" />
</Style>
</telerik:CategoricalAxis3D.LabelStyle>
</telerik:CategoricalAxis3D>
</telerik:RadCartesianChart3D.XAxis>
<telerik:RadCartesianChart3D.YAxis>
<telerik:CategoricalAxis3D Title="Tube">

Hi,
I have a list of workers, whom all needs to have an amount paid by way of their hours times a value.
I have a WorkerModel class:
public class WorkerModel{ public string Name { get; set; } public int HoursWorking { get; set; }}Then I have a CompanyModel that contains the workers:
public class CompanyModel{ private ObservableCollection<WorkerModel> _workers = new ObservableCollection<WorkerModel>(); public ObservableCollection<WorkerModel> Workers { get { return _workers ; } set { _workers = value; } }}And then I have a ViewModel that allows me to bind to the view:
public class MainViewModel : ViewModelBase{ private readonly CompanyModel _company; public MainViewModel() { _company= new CompanyModel(); } public ObservableCollection<CompanyModel > Workers { get { return _company.Workers; } } public decimal PayoutPerHour { get { return 71M; } }}Lastly my view looks like this:
<telerik:RadGridView ShowGroupPanel="False" HorizontalAlignment="Left" telerik:StyleManager.Theme="Summer" AutoGenerateColumns="False" GroupRenderMode="Flat" NewRowPosition="Bottom" ItemsSource="{Binding Workers}" Grid.Column="0"> <telerik:RadGridView.Columns> <telerik:GridViewDataColumn Header="Name" DataMemberBinding="{Binding Path=Name}" Width="230"></telerik:GridViewDataColumn> <telerik:GridViewExpressionColumn Header="Payout" Width="100" Expression="HoursWorking * PayoutPerHour"></telerik:GridViewExpressionColumn></telerik:GridViewDataColumn> </telerik:RadGridView.Columns> </telerik:RadGridView>
My goal is to have the HoursWorking from the WorkerModel, multiply with the PayoutPerHour thats in the ViewModel. I have in this example made the PayoutPerHour a static value, which it is not in my full example. I need the Expressioncolumn to update whenever either of those two properties are updated. But I can't tell the viewmodel what the WorkerModel is doing, since they are in a collection in the CompanyModel.
Any clever way to do this?
