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?

                                    ser2.LegendLabel = "Series 2 Label";

                            }         

and that is the XAML part:

                                <Grid x:Name="LayoutRoot">         
                                <control:RadChart x:Name="RadChart1">         
                                    <control:RadChart.DefaultView>         
                                        <chart:ChartDefaultView>         
                                                     
                                            <chart:ChartDefaultView.ChartLegend>         
                                                <chart:ChartLegend x:Name="CustomLegend" Header="Legend Header" UseAutoGeneratedItems="True">         
                                                </chart:ChartLegend>         
                                            </chart:ChartDefaultView.ChartLegend>         
                                            <chart:ChartDefaultView.ChartTitle>         
                                                <chart:ChartTitle>         
                                                    <TextBlock Text="Declarative RadChart"/>         
                                                </chart:ChartTitle>         
                                            </chart:ChartDefaultView.ChartTitle>         
                                        </chart:ChartDefaultView>         
                                    </control:RadChart.DefaultView>         
                                </control:RadChart>         
                                 
                            </Grid>         
but now... i don't have the Legend generated. So what's missing? How to get back the Legend if i use something like MVVM?

How to change selected day hover color in month and other views?

Hi

I'm trying to customise the RadCalendar, but I do not see how I can change the hover over and selection colors for days when in certain views (E.g. month/week view)

I have tried editing the Template using Blend and also checked out the post at
http://www.telerik.com/community/forums/wpf/calendar/how-to-change-datepicker-monthview-s-header.aspx

which is somewhat relevant, but I do not see any such property.

How should I go about achieving this?

Regards

Q2 Sample Released

I cannot get the Sample project to show the GridView from the Q2 release. So, I decided to open the project in debug and see what was going on. I find it very hard to believe that you are releasing a sample that compiles with 13 warnings of Obsolete classes. How are we supposed to be using the sample project as a basis of our development if you are delivering usages of obsolete items?

Not pleased at all with this...

ControlTemplate RadCarousel ScrollViewer

I am using a RadCarousel and would like to change how the navigation buttons look. I am assuming that the way to go about this is to use a ControlTemplate, however I have been unable to affect the visual appearance of the ScrollViewer. Does anyone have an example of how to apply custom styling to the scrollviewer in a RadCarousel?

Thanks

Conditional formatting of RadPanelBar items

Hi

My RadPanelBar is bound to a collection of objects like this:

XAML:

    
            <HierarchicalDataTemplate x:Key="hdt" ItemsSource="{Binding ClientPublications}">                         
        
                        <TextBlock Text="{Binding Name}"></TextBlock> 
        
            </HierarchicalDataTemplate> 
        
            <telerik:RadPanelBar x:Name="reportMenuPanelBar" Grid.Row="1" Margin="1,0,1,1" ItemsSource="{Binding}" ItemTemplate="{StaticResource hdt}" Selected="reportMenuPanelBar_Selected"> 
        
            </telerik:RadPanelBar>

C#:

    
            IList<ClientReport> reports = mgr.GetAllClientReports(); 
        
            reportMenuPanelBar.DataContext = reports;

I want the textweight for the child panel bar items to be different (i.e. bold or normal) depending on the value of an object's property.

How can I do this?

Thanks.
