InformationLayer binding

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.
