Hello

We are developing WPF aplication with telerik controls ver.2010.1.603
Now we bought licence for your controls ver 2010.2.0812.
And application stopped to work properly.

Here is code causes problem.

Here is our control, that is binded to two DateTime Objects. With ver. 2010.1.603
it was working fine, but with new one we have null exception, when we want to get
MarketDepthFrom, or MarketDepthTo

<

controls:PeriodControl From="{Binding Path=MarketDepthFrom, Mode=TwoWay}" To="{Binding Path=MarketDepthTo, Mode=TwoWay}" />

Here is XAML of our control:

<UserControl x:Class="LT.Desk.Controls.PeriodControl"

And here is code behind for it:

public partial class PeriodControl

{

public DateTime? From

{

get { return (DateTime)GetValue(FromProperty); }

set { SetValue(FromProperty,value); }

}

public DateTime? To

{

get { return (DateTime)GetValue(ToProperty); }

set { SetValue(ToProperty, value); }

}

public PeriodTypeEnum PeriodType

{

get { return (PeriodTypeEnum)GetValue(PeriodTypeProperty); }

set { SetValue(PeriodTypeProperty, value); }

}

public static DependencyProperty FromProperty = DependencyProperty.Register("From", typeof(DateTime?), typeof(PeriodControl));

public static DependencyProperty ToProperty = DependencyProperty.Register("To", typeof(DateTime?), typeof(PeriodControl));

public static DependencyProperty PeriodTypeProperty = DependencyProperty.Register("PeriodType", typeof(PeriodTypeEnum), typeof(PeriodControl));

public PeriodControl()

{

InitializeComponent();

fromDP.SelectedDate =

DateTime.Today;

toDP.SelectedDate = DateTime.Today;

From = DateTime.Today;

To = DateTime.Today;

PeriodTypeCombo.SelectedIndex = 0;

}

private void fromDP_SelectionChanged(object sender, SelectionChangedEventArgs e)............

private void toDP_SelectionChanged(object sender, SelectionChangedEventArgs e).............

private void Next_Click(object sender, RoutedEventArgs e).................

private void PeriodTypeCombo_SelectionChanged(object sender, SelectionChangedEventArgs e).............

}

Please help me if you know the answer
we have 2 days left to deadline so it is
quite urgent

Regards
Michal
