Hi,

I've notcied that when I try to print a document but push the cancel button the document is still sent to the printer.
Has anyone else noticed this?

Here's my print method:

private void btnPrint_Click(object sender, RoutedEventArgs e)

{

this.radRichTextBox.Print("TAS2 Spec", PrintMode.Native);

}

Thanks for your time,

PasswordBox in MetroTheme

I am trying to apply the telerik metro theme to the WPF controls. While most controls looks OK, the PasswordBox somehow received a strange double border (see attached image). This issue seem to only affect the Metro Theme, other themes such as the Windows7 Theme looks ok.

Floating RadPaneGroup with RadGridView is stealing focus

Hello,

In a RadPaneGroup with a RadGridView we are showing some detials of a SQL search. In the background is a ViewModel and one of the property contains the resultrecords as array. Each new search request will create a new array of records and through a binding it changes the ItemsSource property of RadGridView.

new Version 2012.2.725.40: the focus will jump into the RadGridView when RadPaneGroup is floating
old Version 2012.1.215.40: its all ok, the Fosuce stay in e.g. TextBox

a SampleApp below

<Window x:Class="RadGridViewFocusStealing.MainWindow"

problem with extensions

All of a sudden I can't run any app with telerik WPF. I upgraded to Q2 2012 and it crashed visual studio without completing. Now I can't run existing projects or start new ones using WPF. I tried uninstalling and reinstalling but no difference.

UpdateLayout not working

Hi,

in scheduleview I am do following:
- every time the visible range is changed I set the AppointmentsSource = null. After that I add some new Appointments (which fit into the visible range). After that I call UpdateLayout().

            scheduleView.BeginInit();
            scheduleView.AppointmentsSource = null;
            scheduleView.AppointmentsSource = observableAppointments;
            scheduleView.EndInit();
            scheduleView.UpdateLayout();

This is ok, when I click the back and forward buttons on schedule view. But when I change from Week View into Day View, I get an exception. I debugged schedule view and got the exception in AppointmentsPanel.cs in

private void UpdateMaxDesiredSize(GroupHeader header, bool isHorizontal)
       {
           header.Measure(infinity);

           int level = header.Level;
           Size desiredSize = header.DesiredSize;
           int adjustLevel = level - 1;

           double levelMaxDesiredLength = this.GetMaxDesiredLength(adjustLevel);

           double length;
           if (isHorizontal)
           {
               length = header.DesiredSize.Width - header.BorderThickness.Right;
           }
           else
           {
               length = header.DesiredSize.Height - header.BorderThickness.Bottom;
           }
           levelMaxDesiredLength = Math.Max(levelMaxDesiredLength, length);
           this.headerMaxLengthLevels[adjustLevel] = levelMaxDesiredLength; Here headerMaxLengthLevels has zero entries.
       }

What's the reason for this?

Regards,
Ronald
