Hi.
I just upgraded my project with the lastest DLL's of Q1 2010 version.
I have a view with a RadGridView control displaying a custom object, with the custom columns defined.

The definition of the columns is something like this:

<

 

TelerikControls:RadGridView.Columns>

 

 

 

<TelerikControls:GridViewSelectColumn Header="" />

 

 

 

<TelerikControls:GridViewDataColumn DataMemberBinding="{Binding CodigoAbonado}" Header="{DynamicResource LBL_AccionComercialView_CodigoAbonado}" IsReadOnly="True" IsFilterable="False"/>

 

 

 

<TelerikControls:GridViewDataColumn DataMemberBinding="{Binding CodigoPostal}" Header="{StaticResource LBL_AccionComercialView_CodigoPostal}" IsReadOnly="True" IsFilterable="False"/>

 

 

 

<TelerikControls:GridViewDataColumn Width="Auto" DataMemberBinding="{Binding CuentaNombre}" Header="{DynamicResource LBL_AccionComercialView_NombreCuenta}" IsReadOnly="True" IsFilterable="False"/>

 

 

 

<TelerikControls:GridViewDataColumn DataMemberBinding="{Binding IdFranquicia}" Header="{DynamicResource LBL_AccionComercialView_Franquicia}" IsReadOnly="True" IsFilterable="False"/>

 

 

 

<TelerikControls:GridViewDataColumn DataMemberBinding="{Binding Envios}" Header="{DynamicResource LBL_AccionComercialView_NumeroEnvios}" IsReadOnly="True" IsFilterable="False"/>

 

 

 

<TelerikControls:GridViewDataColumn DataMemberBinding="{Binding Facturacion}" Header="{DynamicResource LBL_AccionComercialView_Facturacion}" IsReadOnly="True" IsFilterable="False"/>

 

 

 

</TelerikControls:RadGridView.Columns>

 

 

 

where "TelerikControls" is
xmlns:TelerikControls="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.GridView"

The application crashed with the following error:

"Null object reference exception.

Any idea of what's happening?
Is version Q1 2010 not stable for this control?

Thanks in advance.

Hi,
How can i access InvalidBorder of the row in Q1 2010 release?
In older release i use to do 

void DataGrid_RowLoaded(object sender, RowLoadedEventArgs e)
{
Rectangle rect = e.Row.ChildrenOfType<Rectangle>() 
                .Where(c => c.Name == "InvalidBorder")
                .First() as Rectangle;

But in Q1 2010 release this statement gives exception 
 "Expression cannot contain lambda expressions"
exception message says "Sequence contains no elements"

thx

Hello, we want to provide forms, e.g., to administer master data for article (Windows Forms or better WPF).
The users should be able to arrange themselves the fields (text fields, combo, etc.) to form the surface adaptably. Do you have a proposal, how can one realise such a thing?

Hi,
I have UserControl with RadGridView. If start it from WPF application everything is OK, but if I start from VB6 then grouping in RadGridView doesn't work. In earlier versions was ok.
Is there currently a work around for this issue?

Thanks in advance,

Is zooming/scrolling supported in XBAP?
I checked the http://demos.telerik.com/wpf/ (zooming and scrolling section) and there was a message saying "This example is not available in XBAP".

Hello,

I'm trying to bind a collection of objects that I would like to display in a hierarchical fashion in the radgridview. I have one parent item that has roughly about 600 child items. When I try to expand the parent to display the child items, the process is very slow and takes around 10 seconds to finalize the display. Has anyone here had the same experience when trying to display a large child set? Andi if so, what solution did you find fixed the problem?

Thanks in advance.

I have
in xaml the following GridViewColumn in

<ctrls:RadGridView >
            <telikControls:RadGridView.Columns>
<telikControls:GridViewComboBoxColumn
                        Name="dboDocCollections"
                        Header="Some Header"
                        IsReadOnly="True"
                        IsGroupable="True"
                        SelectedValueMemberPath="Id"
                        DisplayMemberPath="Name"
                        DataMemberBinding="{Binding Path=Batch.DocCollectionId}"

i have a structure for GridViewComboBoxColumn:
  Class Dummy
    { public long Id {get;set};
      public Name{get;set;}
     }

.............................
Code behind I'm assign a source (List<Dummy>()) for GridViewCombo, but the RadGridView don't display data (DisplayMember) accordingly for Combo source assigned.

I want to mention that in previous version of RadGridView  assembly same code worked ok!
