Hello,

I have an MVVM application.
In this application I use RadMap control with search engine via BingSearchProvider class.
If I binding result of work BingSearchProvider as ObservableCollection<Location> all works perfectly,

    
            <telerik:InformationLayer x:Name="informationLayer"  
        
                ItemsSource="{Binding Path=LocationData.SearchResult}"> 
        
             <telerik:InformationLayer.ItemTemplate> 
        
            .... 
        
            public ObservableCollection<Location> SearchResult { get; private set; } 
        
            private void geoHelper_SearchCompleted(object sender, LocSearchCompletedEventArgs e) 
        
            { 
        
                SearchResult.Clear(); 
        
                var searchResult = e.Locations as ObservableCollection<MyMapItem>; 
        
                foreach(MyMapItem loc in searchResult) 
        
                    SearchResult.Add(loc.Location); 
        
            }

but if I try to wrap result in MyMapItem and try binding ObservableCollection <MyMapItem>
the map refuses to display search result positions on InformationLayer.

    
            <telerik:InformationLayer x:Name="informationLayer"  
        
                ItemsSource="{Binding Path=LocationData.SearchResult.Location}"> 
        
             <telerik:InformationLayer.ItemTemplate> 
        
            .... 
        
            public class MyMapItem 
        
            { 
        
                public Location Location 
        
                { 
        
                    get; 
        
                    set; 
        
                } 
        
                public string Title 
        
                { 
        
                    get; 
        
                    set; 
        
                } 
        
                public string Description 
        
                { 
        
                    get; 
        
                    set; 
        
                } 
        
            } 
        
            public ObservableCollection<MyMapItem> SearchResult { get; private set; } 
        
            private void geoHelper_SearchCompleted(object sender, LocSearchCompletedEventArgs e) 
        
            { 
        
                SearchResult.Clear(); 
        
                var searchResult = e.Locations as ObservableCollection<MyMapItem>; 
        
                foreach(MyMapItem loc in searchResult) 
        
                   SearchResult.Add(loc); 
        
            }

Rad chart negative values

Hello all.

I'm working on stacked bar and i have one question about negative values.
Is it possible to show them on chart? Is it supported by <telerik: RadChart> control?
I have 5 vertical bars with 5 segments. See attached image, please.
You will be able to see that grey part from first bar is missing.
that one has negative value.
Is there any way / property which says to graph that it must be moved a little bit to the top and to show segnemt with negative value?

Binding to the IsExpandable Proeprty

Hi ... I have a child grid for which I would like to show the IsExpandable button only if there is data in the objects child collection. I have tried the following XAML

</Style>

The converter returns a boolean if the child collection has a count. This collection is asynchronous and returns a only result after the RowLoaded event has already run.

Weirdly this same Xaml works for the Expanded property.

Hope you can help

John .

search complex displaymember

i have got a combobox which has set the RadComboBox.ItemTemplate to a combined string

<telerik:RadComboBox x:Name ="blah" HorizontalAlignment="Left" Margin="0,26.04,0,0" VerticalAlignment="Top" Width="167.54" d:LayoutOverrides="HorizontalAlignment" ItemsSource="{Binding Source={StaticResource respondentViewSource}}" >

so how can i have a search text area that actually searches the "displaymember" or "itemtemplate"
i think it's to do with telerik:TextSearch.TextPath, but i don't what value is expected in that attribute.

Multiple Heading Rows

Hi.

I would like to have more than 1 row as a heading to my grid.
I would like to have a heading that is applicable to a couple of columns, with each underlying column still having its own heading.

It should be simular to the formatting that you can do in excel, when you merge a couple of columns into 1 column, and still have columns underneath it, example
------------------------------------
| Data Group |
------------------------------------
|Column1|Column2|Column3|
------------------------------------

I have a project where I need to add columns to my radgrid in code, so please help with a WPF C# example.

Thanks.

Close tabs - RadTabControl + Prism

Hello,

I'm a beginner in WPF and I need your help to do something.

I want to add a system to close tabs for users. But I can't do it !
I found a video here : http://tv.telerik.com/wpf/prism/introduction-prism-with-radcontrols-wpf and I use the same thing for RadTabControl. So I'm using MS Composite Application Guidance and the RegionManager.

So I have this code id my main project :

    
            <telerik:RadTabControl Name="tabControlClient" DockPanel.Dock="Right" cal:RegionManager.RegionName="MainRegion" Margin="10 0 10 10" ScrollMode="Viewport" DropDownDisplayMode="Visible" DisplayMemberPath="Content"> 
        
                        <telerik:RadTabControl.ItemContainerStyle> 
        
                           <Style TargetType="{x:Type telerik:RadTabItem}"> 
        
                                <Setter Property="Header" Value="{Binding DataContext.HeaderInfo}" /> 
        
                                <Setter Property="Height" Value="25" /> 
        
                                <Setter Property="IsSelected" Value="True" /> 
        
                            </Style> 
        
                        </telerik:RadTabControl.ItemContainerStyle> 
        
            </telerik:RadTabControl>

In my Module Project I copy the code on the video :

    
            public String HeaderInfo 
        
            { 
        
                 get { return "Labs Module"; } 
        
            } 
        
            #region INotifyPropertyChanged Membres 
        
            public event PropertyChangedEventHandler PropertyChanged; 
        
            protected void OnPropertyChanged(String propertyName) 
        
            { 
        
                 if (this.PropertyChanged != null) 
        
                 { 
        
                      this.PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); 
        
                 } 
        
            }

It work ! But now I want to add a close system. So I search the solution in this forum and I found this : How to Add Close Button to the Tab Headers
So I complete my code in my main project like this :

    
            <telerik:RadTabControl Name="tabControlClient" DockPanel.Dock="Right" cal:RegionManager.RegionName="MainRegion" Margin="10 0 10 10" ScrollMode="Viewport" DropDownDisplayMode="Visible" DisplayMemberPath="Content"> 
        
                        <telerik:RadTabControl.ItemContainerStyle> 
        
                           <Style TargetType="{x:Type telerik:RadTabItem}"> 
        
                                <Setter Property="Header" Value="{Binding DataContext.HeaderInfo}" /> 
        
                                <Setter Property="HeaderTemplate"> 
        
                                    <Setter.Value> 
        
                                        <DataTemplate> 
        
                                            <Grid> 
        
                                                <TextBlock Text="{Binding Header}"></TextBlock> 
        
                                                <Button Grid.Column="1" Margin="3 0 0 0" Content="x" Width="16" 
        
                                                   Height="16" HorizontalAlignment="right"/> 
        
                                            </Grid> 
        
                                        </DataTemplate> 
        
                                    </Setter.Value> 
        
                                </Setter> 
        
                                <Setter Property="Height" Value="25" /> 
        
                                <Setter Property="IsSelected" Value="True" /> 
        
                            </Style> 
        
                        </telerik:RadTabControl.ItemContainerStyle> 
        
                    </telerik:RadTabControl>

But only close button appear and not the header text.
So how I can use this two solution to have "Header text + close button" please ?

Thank you in advance.
Best Regards
