RadPdfViewer.Print on Windows 10 - PDF goes to "Spooling" and disappears.

Hello,

We are facing this strange issue with PDFViewer.Print functionality on Windows 10 only.

Attached is the sample using latest Telerik dlls (Telerik_UI_for_WPF_2015_2_728_Dev.msi). The problem is - once we print - it goes into the Printing queue and shows "Spooling" but does not print - rather disappears after some time. Please advise.

class Program

{

/// <summary>

/// Main method.

/// </summary>

/// <param name="args">The args.</param>

[STAThread]

static void Main(string[] args)

{

string fileName = "CMI9063.pdf";

if ((args != null) && (args.Length > 0))

{

fileName = args[0];

}

// Load the PDF file.

byte[] buffer = LoadPdfFile(fileName) ?? new byte[] { };

using (MemoryStream stream = new MemoryStream(buffer))

{

PrintDialog printDialog = new PrintDialog { UserPageRangeEnabled = true };

if (printDialog.ShowDialog() == true)

{

RadPdfViewer radPdfViewer = new RadPdfViewer { DefaultFormatProviderSettings = FormatProviderSettings.ReadOnDemand };

radPdfViewer.ClearDocument();

radPdfViewer.Document = new PdfFormatProvider(stream, FormatProviderSettings.ReadOnDemand).Import();

radPdfViewer.Print(printDialog, PrintSettings.Default);

//System.Windows.MessageBox.Show("Successfully print to \"" + printDialog.PrintQueue.FullName + "\"", "Print", System.Windows.MessageBoxButton.OK, System.Windows.MessageBoxImage.Information);

}

private static byte[] LoadPdfFile(string filePath)

{

byte[] buffer;

string folder = Directory.GetCurrentDirectory();

if (!filePath.StartsWith(folder))

{

filePath = Path.Combine(folder, filePath);

}

//load from physical path

if (File.Exists(filePath))

{

using (FileStream fs = new FileStream(filePath, FileMode.Open))

{

buffer = new byte[fs.Length];

fs.Read(buffer, 0, buffer.Length);

}

else

{

return null;

}

return buffer;

}

CellTemplate horizontal scrolling is very slow.

If I use CellTemplate and then horizontally scroll so column isn't visible then scroll back I have a noticeable slowdown (jerk) in scrolling.

If I replace this code with using DataMemberBinding without CellTemplate I don't see this problem.

Any advice on how to fix this problem?

(saw some old threads about it but not sure what's the resolution).

Multiple Sorting

Hi,

i use a RadGridView bound to a ObservableCollection<Calls> with some Columns like Name, Number, Date, Time,...

The Column "Date" ist declared as DateTime in my ViewModel and the Column "Time" is a string. I have to sort my
Collection by Date and Time:

Comin from log:

Prusik#4862416#8:30#20.10.2016#incoming.png#(284,1,0)
Prusik#4862416#8:40#20.10.2016#incoming.png#(284,1,0)
Prusik#4862416#8:50#20.10.2016#incoming.png#(284,1,0)
Golf & Thermenresort Stegersbach GmbH#06803280292#14:00#19.10.2016#incoming.png#(16364,0,0)
Golf & Thermenresort Stegersbach GmbH#06803280292#13:00#19.10.2016#incoming.png#(16364,0,0)

Should be sorted to

Prusik#4862416#8:50#20.10.2016#incoming.png#(284,1,0)
Prusik#4862416#8:40#20.10.2016#incoming.png#(284,1,0)
Prusik#4862416#8:30#20.10.2016#incoming.png#(284,1,0)
Golf & Thermenresort Stegersbach GmbH#06803280292#14:00#19.10.2016#incoming.png#(16364,0,0)
Golf & Thermenresort Stegersbach GmbH#06803280292#13:00#19.10.2016#incoming.png#(16364,0,0)

What is to do to geht thisrunning?

And i also want to insert a new incoming call on top of the RadGridView?

Thanks a lot
Best Regards
Rene

SchedulerView rendering broken with .NET 4.6.2

Hi,

After the installation of Windows 10 Anniversary Update (1607) we observed that the rendering of the SchedulerView control in our application is broken. Especially the display of Resources is affected (e.g. Resource headers are multiplied randomly on the whole control). We installed the .NET 4.6.2 on some older system and got the same problem. I found information about the changes in .NET 4.6.2 https://msdn.microsoft.com/en-US/library/ms171868(v=vs.110).aspx#WPF462. It seems the guys at Microsoft did some changes to the group sorting area. My question is - did anyone experience similar issues after the recent updates? Any hints are appreciated.

propertygrid not responding to RefreshPropertiesAttribute

hi dear telerik team

assume i have a property like the below:

[RefreshProperties(RefreshProperties.All)]

public MyType MyProperty

{

get

{

return _myProperty;

}

set

{

_myProperty=value;

   RaisePropertyChanged("MyProperty ");

}

}

 
public bool OtherProperty2
{ 
 get
 { 
  return _otherProperty2; 
 } 
 set
 { 
  _otherProperty2=value;

  if(value)

  {

    MyProperty = new MyType();

  }

  else

  {

    MyProperty = null;

  }



   RaisePropertyChanged("OtherProperty2");
 } 
}

well MyProperty defaults to null so what i see at the begining in the property grid is:

MyProperty
OtherProperty2 false;
OtherProperty3
OtherProperty4

then when i set OtherProperty2 to true the property grid must look like this:

+ MyProperty
OtherProperty2 true;
OtherProperty3
OtherProperty4

and vice versa. but this doesnt happen! and for this to happen i am forced to do something to manualy refresh the property grid like switching between the A-Z view and GroupView

note that MyProperty has browsable properties like Name and LastName in it.

thank you very much in advance for your help
