WPF window fails to load properly in designer
I have been developing an application in WPF using the RadControls for WPF trial version (2009 Q3 I think) over the last few months. Just last week I was able to purchase the RadControls suite and installed them on my machine. Everything has been working fine, even as early as this morning, until this afternoon. For some unexplained reason, my main window no longer appears at design time. By trial and error, I have narrowed the problem down to the inclusion of the references to Telerik.Windows.Controls, Telerik.Windows.Controls.Navigation, and Telerik.Windows.Data. Removing these references and code that requires them resolves the issue.

To test this, I created a new project (WPF application) in VS2008. The application built and ran without me making any modifications to it. Then, I added the references listed above and attempted to run it again. The application runs, but at design time the main window Window1.xaml is not displayed. Instead, I get the following exception information:

Exception has been thrown by the target of an invocation.

at System.RuntimeMethodHandle._InvokeConstructor(Object[] args, SignatureStruct& signature, IntPtr declaringType) at System.RuntimeMethodHandle.InvokeConstructor(Object[] args, SignatureStruct signature, RuntimeTypeHandle declaringType) at System.Reflection.RuntimeConstructorInfo.Invoke(BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture) at System.RuntimeType.CreateInstanceImpl(BindingFlags bindingAttr, Binder binder, Object[] args, CultureInfo culture, Object[] activationAttributes) at System.Activator.CreateInstance(Type type, BindingFlags bindingAttr, Binder binder, Object[] args, CultureInfo culture, Object[] activationAttributes) at Microsoft.Windows.Design.Features.FeatureManager.FeatureConnectorEntry.AttemptActivate() at Microsoft.Windows.Design.Features.FeatureManager.FeatureConnectorEntry.OnRequirementsChanged(Object sender, EventArgs e) at Microsoft.Windows.Design.RequirementValidator.OnRequirementChanged(Object sender, EventArgs e) at Microsoft.Windows.Design.RequirementSubscription.OnRequirementChanged() at Microsoft.Windows.Design.RequiresContextItemAttribute.RequireContextItemSubscription.OnContextItemChanged(ContextItem item) at Microsoft.Windows.Design.SubscribeContextCallback.Invoke(ContextItem item) at Microsoft.Windows.Design.EditingContext.DefaultContextItemManager.OnItemChanged(ContextItem item) at Microsoft.Windows.Design.EditingContext.DefaultContextItemManager.SetValue(ContextItem value) at Microsoft.Windows.Design.Interaction.DesignerView.set_Context(EditingContext value) at MS.Internal.Designer.SimpleViewManager.get_View() at Microsoft.Windows.Design.Documents.MarkupDocumentManager.get_View() at MS.Internal.Host.PersistenceSubsystem.get_DocumentView() at MS.Internal.Host.Designer.get_View() at MS.Internal.Designer.VSDesigner.Load() at MS.Internal.Designer.VSIsolatedDesigner.VSIsolatedView.Load() at MS.Internal.Designer.VSIsolatedDesigner.VSIsolatedDesignerFactory.Load(IsolatedView view) at MS.Internal.Host.Isolation.IsolatedDesigner.BootstrapProxy.LoadDesigner(IsolatedDesignerFactory factory, IsolatedView view) at MS.Internal.Host.Isolation.IsolatedDesigner.BootstrapProxy.LoadDesigner(IsolatedDesignerFactory factory, IsolatedView view) at MS.Internal.Host.Isolation.IsolatedDesigner.Load() at MS.Internal.Designer.DesignerPane.LoadDesignerView()

Again, I did NOTHING to this project except add the references to it. Removing the references causes the exception to disappear and the window is displayed at design time as expected.

This exception is a little different from the exception I get in my other application, which contains two nested RadTabControls. Here is that exception:

This application will only display the main window at design time if I remove the references I mentioned above. Even removing all of the RadTabControl XAML code does not allow the window to be displayed if the references are still included.

The only odd thing I remember seeing immediately before this started happening was a green balloon appearing on the Telerik menu in VS2008 indicating there was an upgrade available and asking if I wanted to upgrade my project. I ignored the message because I did not want to affect my project until I reached a point where I could deal with that by itself. After this exception started to occur, I tried running the upgrade to see if that would resolve the problem, but it did not. I also uninstalled ALL Telerik WPF controls from my machine and re-installed the 2010_0309_DEV version. (JustCode is also installed on my machine)

Here is my XAML code for the window that will not load in the designer:

Disable validation on RadGridView
Hi,
I have a data object that implements INotifyDataErrorInfo.
Unfortunately the support for this in RadGridView is still flaky and there are some visual problems so i am using my own custom style to control validations.

I turned off validation binding but this seems to only solve half my problem.
I now have the following problem - whenever i try to edit a cell that has validation errors i cannot leave the cell unless i press Esc.
Our application flow permits validation errors to exist so the user should not be forced to correct an error before they can move on to something else.

So my question is : how do i turn off editing validation? 

Thanks,
Yossi.

Problem with drap and drop
I have the below xaml code, when I tried to drap and drop the Food Categories to anywhere under the Sports Categories, the Pizza and Pasta sub items lost their left indent under the Food Categoeis. Basically, what I mean is when I drap and drop one root level of treeview item to anywhere under another treeview root item, the layout turned out to be not as expected.

Below is my code, could you please try what I described above and see that happens? Thanks.

Hi,

I have a grid defined like this:

                                      AutoGenerateColumns="False" RowDetailsVisibilityMode="Visible" IsReadOnly="True" ShowColumnHeaders="False"  
                                      RowIndicatorVisibility="Collapsed" GridLinesVisibility="Horizontal"> 
                    <Controls:RadGridView.ChildTableDefinitions> 
                        <Controls:GridViewTableDefinition /> 
                    </Controls:RadGridView.ChildTableDefinitions> 
                    <Controls:RadGridView.Columns> 
                        <Controls:GridViewComboBoxColumn DataMemberBinding="{Binding Path=Id}"  
                                                         DisplayMemberPath="Name"  
                                                         SelectedValueMemberPath="Id"  
                                                         ItemsSource="{Binding Source={StaticResource dishTypeData}}" />  
                    </Controls:RadGridView.Columns> 
                    <Controls:RadGridView.HierarchyChildTemplate> 
                        <DataTemplate> 
                            <Controls:RadGridView ItemsSource="{Binding Path=MenuItems}" ShowGroupPanel="False" CanUserDeleteRows="False" CanUserInsertRows="False" CanUserFreezeColumns="False" 
                                                  AutoGenerateColumns="False" RowDetailsVisibilityMode="Visible" IsReadOnly="False" ShowColumnHeaders="False"  
                                                  RowIndicatorVisibility="Collapsed" GridLinesVisibility="Horizontal"> 
                                <Controls:RadGridView.Columns> 
                                    <Controls:GridViewComboBoxColumn DataMemberBinding="{Binding Path=FoodId}"  
                                                                     ItemsSource="{Binding Source={StaticResource foodData}}" 
                                                                     DisplayMemberPath="Name" 
                                                                     SelectedValueMemberPath="Id" /> 
                                    <Controls:GridViewDataColumn DataMemberBinding="{Binding Path=PortionSize}" /> 
                                </Controls:RadGridView.Columns> 
                            </Controls:RadGridView> 
                        </DataTemplate> 
                    </Controls:RadGridView.HierarchyChildTemplate> 
                </Controls:RadGridView> 


What  is the property to make all the tree children expanded (similar to clicking the + sign on all) ?

Thank you,

I must admit I cannot do it....
Thanks a lot....

For better details what I try to do is in the following code

<telerik:RadGridView x:Name="radGridInvoiceDetails" ShowGroupPanel="False" AutoGenerateColumns="False" Height="245" Width="920" ItemsSource="{Binding}" HorizontalAlignment="Center" DataLoadMode="Asynchronous">

                                <Label Content="Visualizza la bolla"/>  
                            </StackPanel> 
                        </Button.ToolTip> 
                    </telerik:RadButton> 
                </DataTemplate> 
            </telerik:GridViewColumn.CellTemplate> 
        </telerik:GridViewDataColumn> 
    </telerik:RadGridView.Columns> 
    <!--<telerik:RadGridView.GroupDescriptors> 
        <telerik:GroupDescriptor Member="ProductFamilyDescription" SortDirection="Ascending"/>  
        <telerik:GroupDescriptor Member="ProductDescription" SortDirection="Ascending" /> 
    </telerik:RadGridView.GroupDescriptors>--> 
</telerik:RadGridView> 
 

in the radgridview of this XAML code I have to programmatically add two groups,the second of which must also make 3 sum funtions.
Following examples I have found in this site I have written this code

private void InitInvoiceDetails()  
{  
    try 
    {  
        radGridInvoiceDetails.SelectedItem = null;  
        radGridInvoiceDetails.ItemsSource = null;  
        radGridInvoiceDetails.GroupDescriptors.Clear();  
 
        if (CurrentMaster != null)  
        {  
            var collection = from d in dc.InvoiceDetails  
                             where d.IdInvoiceMaster == CurrentMaster.Id  
                             orderby d.IdProductType, d.ProductDescription, d.BillNumber  
                             select d;  
            radGridInvoiceDetails.ItemsSource = collection.ToList();  
        }  
 
        GroupDescriptor descriptor = new Telerik.Windows.Data.GroupDescriptor();  
        descriptor.Member = "ProductFamilyDescription";  
        descriptor.DisplayContent = "Famiglia";  
        descriptor.SortDirection = ListSortDirection.Ascending;  
        radGridInvoiceDetails.GroupDescriptors.Add(descriptor);  
 
        descriptor = new Telerik.Windows.Data.GroupDescriptor();  
        var sumFunction = new Telerik.Windows.Data.SumFunction();  
        sumFunction.ResultFormatString = "{0:N2}";  
        sumFunction.SourceField = "ProductQuantity";  
        sumFunction.Caption = "Totale Quantità";  
        descriptor.AggregateFunctions.Add(sumFunction);  
 
        sumFunction = new Telerik.Windows.Data.SumFunction();  
        sumFunction.ResultFormatString = "{0:N2}";  
        sumFunction.SourceField = "TotalBill";  
        sumFunction.Caption = "Totale Imponibile";  
        descriptor.AggregateFunctions.Add(sumFunction);  
 
        sumFunction = new Telerik.Windows.Data.SumFunction();  
        sumFunction.ResultFormatString = "{0:N2}";  
        sumFunction.SourceField = "TotalVAT";  
        sumFunction.Caption = "Totale Con IVA";  
        descriptor.AggregateFunctions.Add(sumFunction);  
 
        descriptor.Member = "ProductDescription";  
        descriptor.DisplayContent = "Prodotto";  
        descriptor.SortDirection = ListSortDirection.Ascending;  
        radGridInvoiceDetails.GroupDescriptors.Add(descriptor);  
    }  
    catch (Exception ex)  
    {  
        throw ex;  
    }  
}  
 

It happens that the first time I bind data in the radgrid view the groups are duplicated.
The first does not contains the sum values, the second yes.

The second time an exception is thrown.
System.ArgumentException was unhandled by user code  
  Message="The value \"[Group: Key=RCK 25.0 S3 F.FULLER NO; ItemCount=1; HasSubgroups=False; ParentGroup=null];\" is not of type \"Raise.FarinaEzio.SIB.Client.Management.DataContext.InvoiceDetail\" and cannot be used in this generic collection.\r\nParameter name: value" 
  Source="mscorlib" 
  ParamName="value" 
  StackTrace:

       at System.ComponentModel.BackgroundWorker.OnDoWork(DoWorkEventArgs e)  
       at System.ComponentModel.BackgroundWorker.WorkerThreadStart(Object argument)

Hope this details help you to help me...

Theme WindowBackground
When you change the theme in for instance msWord, the whole WindowBackground changes to the choosen theme.
How should this be done with Telerik...
I know you can use:

public Window1()
{
      AppllicationTheme = new VistaTheme();
      InitializeComponent();
 }

But this only effects the RadControls.
How to change the WindowBackground?
