Upgraded to Q2 13 from Q1 13 - some issues

[Rob]

I have two issues after updating from one set of components to another.

1) I previously had the following lines of code which, regardless of grouping/sorting, gave me a collection of objects currently viewable in the grid:

 foreach (GBundlingTradeOutput item in gridTradePackages.Items)
{
projects.Add(item);
}

When the code runs now I receive an error of the following:

Additional information: Unable to cast object of type 'Telerik.Windows.Data.AggregateFunctionsGroup' to type 'PostContract.Common.Classes.GBundlingTradeOutput'.

Why the change and how do i return to the functionality originally intended?

2) I have two datetime properties on objects bound to a grid. When i click on the cell I get the calendar picker and I can select a date which enters the value correctly in the cell. If I enter a value manually such as 01/02/2012 the value doesn't get bound to the property. Is this related to culture? I have a line of code:

this.Language = XmlLanguage.GetLanguage(CultureInfo.CurrentCulture.IetfLanguageTag);

The grid columns are as follows in the xaml:

                <telerik:GridViewDataColumn Width="200"
                                                DataMemberBinding="{Binding Path=AppointmentDate,
                                                                            UpdateSourceTrigger=PropertyChanged}"
                                                Header="Latest Appointment Date" DataFormatString="{} {0:d}"
                                                TextWrapping="Wrap" >
                    </telerik:GridViewDataColumn>
                    <telerik:GridViewDataColumn Width="140"
                                                DataMemberBinding="{Binding Path=StartDate,
                                                                            UpdateSourceTrigger=PropertyChanged}"
                                                Header="Start on Site Date" DataFormatString="{} {0:d}"
                                                TextWrapping="Wrap" >

Many thanks.

Hello Rob,

Unfortunately, we were not able to reproduce the exception due to a lot of missing information about your setup. As the second problem you reported is fixed with our latest official release - Q3 2013, I would suggest you to download it and to give it a try. In case you still get the exception, please open a support ticket and attach a sample demonstrating the issue so we can debug on our side.
