RadGridView- Asynchronous DataLoadMode doesn't refresh grid

Hi,
I have a GridView with binding to an ObservableCollection in the ViewModel.
The GridView DataLoadMode is set to Asynchronous.
When removing an item from the ObservableCollection in the ViewModel, the GridView is not refershed and item is still shown.
If I set DataLoadMode as synchronous , It works fine.

    
            <telerik:RadGridView  
        
              x:Name="RadGridViewGroups" 
        
              Grid.Row="1" 
        
              AutoGenerateColumns="False" 
        
              DataLoadMode="Asynchronous" 
        
              IsReadOnly="True"           
        
              ItemsSource="{Binding Groups}" >

    
            public class GroupsViewModel : INotifyPropertyChanged  
        
            {         
        
                public ObservableCollection<TradingGroup> Groups  
        
                {  
        
                    get 
        
                    {  
        
                        return m_Groups;  
        
                    }  
        
                    set 
        
                    {  
        
                        m_Groups = value;  
        
                        PropertyChanged.OnPropertyChanged(this, "Groups");  
        
                    }  
        
                }  
        
            }

Navigateable Properties in GridCell

Hi.
Small problem:
Imagine a class setup of:

    
            public class DisplayData 
        
            { 
        
               public string Name { get; set; } 
        
               public SomeOtherClass Prop { get; set; } 
        
            } 
        
            public class SomeOtherClass  
        
            { 
        
               public string OtherName { get; set; } 
        
            }

Now I have an ObservableCollection<DisplayData> to display in my Grid.
Problem is the following setup does no display SomeOtherClass nicely (how should it...)

    
            <telerik:GridViewDataColumn  
        
                 Header="Name" 
        
                 DataMemberBinding="{Binding Path=Name, Mode=OneWay}" 
        
                 Width="2*" 
        
                 IsReadOnly="True"/> 
        
            <telerik:GridViewDataColumn  
        
                 Header="Other" 
        
                 DataMemberBinding="{Binding Path=Prop, Mode=OneWay}" 
        
                 Width="3*" 
        
                 IsReadOnly="True"/>

If I change the second column like this:

    
            <telerik:GridViewDataColumn   
        
                 Header="Name"  
        
                 DataMemberBinding="{Binding Path=Name, Mode=OneWay}"  
        
                 Width="2*"  
        
                 IsReadOnly="True"/>  
        
            <telerik:GridViewDataColumn   
        
                 Header="Other"  
        
                 DataMemberBinding="{Binding Path=Prop.OtherName, Mode=OneWay}"  
        
                 Width="3*"  
        
                 IsReadOnly="True"/>

All displays fine. However I loose the Ability to Filter/Group the second column.
I am searching for something like:

    
            <telerik:GridViewDataColumn    
        
                 Header="Name"   
        
                 DataMemberBinding="{Binding Path=Name, Mode=OneWay}"   
        
                 Width="2*"   
        
                 IsReadOnly="True"/>   
        
            <telerik:GridViewDataColumn    
        
                 Header="Other"   
        
                 DataMemberBinding="{Binding Path=Prop, Mode=OneWay}" 
        
                 DisplayMemberPath="OtherName"   
        
                 Width="3*"   
        
                 IsReadOnly="True"/>

And I can't seem to find any solution..

I seem to walking in the dark here.. so could someone please enlighten me ?

Yours,
Nils

Button column and click event

Hello everybody.

We have a RadGridView with 4 columns: 2 are simply text column, while 2 have a button.

The problem we can't figure out is: how we can know the row index number (=item) starting from the button click event?

Thank you for your cooperation.

Attilio Gelosa.

RadTabItem Theme

I am creating tabs on the fly and need to be able to apply a theme to the actual RadTabItem.

I have tried the following with no success:
1) tab1.SetValue(Telerik.Windows.Controls.StyleManager.ThemeProperty, new VistaTheme());
2) Telerik.Windows.Controls.StyleManager.SetTheme(tab1, new VistaTheme());

tab1 is the tab I created:
RadTabItem tab1 = new RadTabItem();

Also, I cannot apply the theme to an existing tab (within the actual XAML) dynamically either. If a RadTabItem exists with name "tab2" on the xaml form and I try and go and programatically apply a theme somewhere in the code it does not apply at all...

Any help with this would be great. I really need to be able to apply themes on the fly to dynamically created telerik objects.

Thanks

GridView inside Canvas

If a I create a simple form with just a RadGridView control:

<Grid>

<telerik:RadGridView Name="radGridView1"/>

</Grid>

As I resize the window, the grid streches with the window and vertical/horizontal scrollbars appear if there's any extra rows/columns in the grid. But if I change the container to a canvas:

<telerik:RadGridView Name="radGridView1"/>

</Canvas>

Then any overflow is hidden. Even if I wrap the RadGridView in it's own grid under the canvas no scrollbars appear. This seems to happen if there's a canvas element anywhere in the container hierarchy.

SelectedItem Object Reference not set

Working with: Version 2009.1.526.35

Trying to set SelectedItem.
Code:

<telerik:RadGridView AutoGenerateColumns="False"
SelectedItem="{Binding Path=Entity, Mode=TwoWay}" IsReadOnly="False"
ItemsSource="{Binding Path=Entities}"

In my constructor of my model I create a instance of Entity (Selected) and a List of Entities(ItemSource).

When I run, I get a Object Reference not Set... exception.
The same code works fine with a ListBox.
