Questions on UI for WPF Forum

Hi guys,

I have a requirement where I need to have VerticalScrollBar appeared right under the column headers.
Well, I was able to archive that by changing the ControlTemplate for the GridView where I moved GridViewHeaderRow to outside of the ScrollViewer. Everything seems to work just fine. Next I wanted to have a star sized columns and that's where I am having a little problem. I need my last Column Header to use all the remaining space; however there still a space of VerticalScrollBar's width on the right. It's not a filler column; simply DataCellsPresenter inside GridViewHeaderRow does not stretching its content all the way. How do I fix this.

Attached is sample pick.

Thanks,

GridView

Populating with a six level hierarchy

Hello there,

Do the gridview support making a six level hierarchy in an easy way?

Right now I'm setting my top data set as ItemsSource and then do a lot of child table definitions. To be able to remove GroupPanel and ColumnHeaders in my child nodes I'm listening on the DataLoading event casting the sender to a GridViewControl. For getting all the child column I have set the AutoGenerateColumns property to true. But I need to remove some of them so I also listening for AutoGeneratingColumn event. Doing this seems a little bit odd!

Another question is if I'm able to update the data at the bottom node in the gridview from a database without destroying the expanded hieararch made by the user?

Am I correct in my assumption that the gridview only support a two level hierarchy in a good manner.

Best wishes from Johan

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 .
