Vertical Navigator

Hi,
I am looking for a vertical navigator control like the navigator on the telerik site or many other sites. I found PanelBar, but Implements this control ICommandSource, so I am able to associate ICommand items with it??
Can I load the content via data binding?

With best regards

Datepicker databinding

Hello!

Currently i am working on an application wich needs two datepickers - a StartDate and an EndDate . I am having problems binding this two controls with DateTime properties on an object . For binding values i am using the attribute SelectedDate = {Binding Path=StartDate}, but no binding is created . I would like to know if this is the correct way of binding this control to date fields or if there is another way of doing this... I have search throught the website/documentation but I can't find a proper response.

Any help would be great !
Thanks,

Binding Problem

I have a radcarousel bound to an objectdataprovider which has an instance of an observablecollection<T> where T is a personentity class in my system. If I change a property value of one of the personentity (like firstname) those changes are not reflected in the Carousel. Any help will be much appreciated.

Column header missing

Hello,

I'm having an issue where the column header is missing when you add a column to the grid after it has initially been created. I have created a sample project that demonstrates my issue, but it appears I can't attach it so I included the code at the end of this post. To reproduce it, just click on the 'Add Column' button. Am I doing something wrong in my code or is this a bug?

In my example I'm also calling Rebind() and UpdateLayout() on the grid after adding the column because if I don't then no data appears in the column, though the column itself is added.

Note: I borrowed the Custom and Order classes from a sample app on this forum.

Thanks,

Joel

3D Doughnut Chart Help

Hi,

I'm trying to create a 3D Dougnut Chart, but are having troubles with the Series Mapping. Using the code below, I get the legend to show color coded items equal to the amount of rows in the table. But nothing else displays.

    
            Doughnut3DSeriesDefinition definition = new Doughnut3DSeriesDefinition();  
        
            definition.LegendDisplayMode = LegendDisplayMode.DataPointLabel;  
        
            radChart1.DefaultSeriesDefinition = definition;  
        
            radChart1.DefaultView.ChartLegend.Header = "TEST DATA";  
        
            SeriesMapping seriesMapping = new SeriesMapping();  
        
            ItemMapping itemMapping = new ItemMapping();  
        
            itemMapping.DataPointMember = DataPointMember.YValue;  
        
            itemMapping.FieldName = "DoubleData";  
        
            seriesMapping.ItemMappings.Add(itemMapping);  
        
            ItemMapping itemMapping2 = new ItemMapping();  
        
            itemMapping2.DataPointMember = DataPointMember.Label;  
        
            itemMapping2.FieldName = "StringData";  
        
            seriesMapping.ItemMappings.Add(itemMapping2);  
        
            radChart1.SeriesMappings.Add(seriesMapping);  
        
            DataTable tt = new DataTable();  
        
            tt = GetDataTable();  
        
            radChart1.ItemsSource = tt;

Any help would be much appreciated. Not really sure how the charting works.

Thanks,

Henry

Lost Focus when using RadNumericUpDown

Hi there !
I have one window control wich holds two grids( one wich will be static - with a banner ) and the other will have two different user controls ( one for the list case and the other for adding/ editing data ) . I am defining several commandbindings & keybinds in order to have a fully functional keyboard shortcut system . The problem appears when I use the RadNumericUpDown control . When I insert a decimal value or other, my window control looses the focus; I have compared the state of the focus before and after using the numericupdown and I can see that the window focus status change ( from true to false )... I guess this happens right when i use the numericupdown control ... Any ideia / suggestions ?

Thanks,
Ivan Frias
