Hi,

I have read in documentation that RadCharts supports binding to a data source with change notification. I assume this means, when a change is made to that data type it will automatically reflect on the graph? I havent been able to succesfully implement this using an ArrayList. Is there a sample application available?

Regards

Setting format of filter list?

I have many 'float' items which I have set to display to one decimal place using DataFormatString="{}{0:0.0}" but when I use the 'filter', some of these are displayed with more than one decimal place, which is confusing. Is there any way to set the filter items to the same format?

Problem with RadProgressBar in WPF

Hi!

I am using <telerik:RadUpload> control.

And everything is working fine. The only problem I have that is

<

telerik1:RadProgressBar Background

when I change background of RadProgressbar it does not cover all space of the item.
There is left a border strip at the left side of item which is still red colored. And this is why I say that changing background
of RadProgressBar does not apply to all available space inside the item.

Please, give me example of how to handle it in silverlight app.

Thanks, My Best Regards!

Anatoliy Abbott.

This is what I have in .xaml file:

programmatically create schema and fill the gridview rows

respectfully,
i want to programmatically create a custom schema (create columns in custom without binding) and fill the gridview with custom data ( add new rows without binding )! I found that the wpf radgridview do not have the rows collection and it seems that is necessary to bind radgridview to a data source for displaying data, but i want to add new rows and columns programatically at run time even if i bound it to data source before! is there any approach for this purpose?!
thanks for your kindness ;)

How do I bind to a list of view models?

I can't get it to display a list of objects which are view models.
Using version 2009.2.701.35 with vb.net in a model/view/view model framework.

This displays nothing:

    
                        <telerik:RadCarousel  
        
                            x:Name="RCAddressList" 
        
                            ItemsSource="{Binding Path=AddressViewModelList}" 
        
                            telerik:StyleManager.Theme="Office_Blue"> 
        
                        </telerik:RadCarousel

This displays the correct number of items, but it is just then name of the object. i.e. 4 addresses in the list means AddressApp.ViewModel.AddressViewModel as text 4 times in the carousel.

    
                        <ListView  
        
                            x:Name="ListView"  
        
                            ItemsSource="{Binding Path=AddressViewModelList}"  
        
                            BorderThickness="0" Background="Transparent" 
        
                            HorizontalAlignment="Stretch" VerticalAlignment="Stretch"> 
        
                            <ListView.ItemsPanel> 
        
                                <ItemsPanelTemplate> 
        
                                    <telerik:RadCarouselPanel /> 
        
                                </ItemsPanelTemplate> 
        
                            </ListView.ItemsPanel> 
        
                        </ListView>

RadDragAndDropManager & Grouping of columns

Hi

I'm using the RadDragAndDropManager along with the RadGridView; it appears like the the column re-ordering and the grouping now no longer work. Do we have to code this manually if we use the RadDragAndDropManager?
