Hello!

Since I updated to 2010 Q1 my CellEditTemplate stopped working. I get an System.InvalidCastException when leaving the textbox.

    
             <telerikGrid:RadGridView  x:Name="ARVolymGridView" AutoGenerateColumns="False" ShowGroupPanel="False" ItemsSource="{Binding ARVolymer, Mode=OneWay, UpdateSourceTrigger=PropertyChanged}" > 
        
                        <telerikGrid:RadGridView.Columns> 
        
                            <telerikGrid:GridViewDataColumn DataMemberBinding="{Binding Sortiment, UpdateSourceTrigger=PropertyChanged}" Header="Sortiment"/> 
        
                            <telerikGrid:GridViewDataColumn DataMemberBinding="{Binding Volym, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" Header="M3f" > 
        
                                <telerikGrid:GridViewDataColumn.CellEditTemplate> 
        
                                    <DataTemplate> 
        
                                        <TextBox Text="{Binding Volym, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}"/> 
        
                                    </DataTemplate> 
        
                                </telerikGrid:GridViewDataColumn.CellEditTemplate> 
        
                            </telerikGrid:GridViewDataColumn> 
        
                        </telerikGrid:RadGridView.Columns> 
        
                    </telerikGrid:RadGridView>

My binding properties:

    
                    public string Sortiment 
        
                    { 
        
                        get { return _arVolym.Sortiment; } 
        
                        set 
        
                        { 
        
                            if (_arVolym.Sortiment != value) 
        
                            { 
        
                                _arVolym.Sortiment = value; 
        
                                OnPropertyChanged("Sortiment"); 
        
                            } 
        
                        } 
        
                    } 
        
                    public int Volym 
        
                    { 
        
                        get { return _arVolym.Volym; } 
        
                        set 
        
                        { 
        
                            if (_arVolym.Volym != value) 
        
                            { 
        
                                _arVolym.Volym = value; 
        
                                OnPropertyChanged("Volym"); 
        
                            } 
        
                        } 
        
                    }

In my application I have an custom designed TextBox to prevent the user to enter invalid values, but the same exception appears for a regular Textbox.

This is extremly annoying that something stopped working when updating to a new and improved (?!) version.
