How to print using Microsoft ReportViewer without showing it

Printing with default printer only works the first time

Hi,

This code works first time very well but second time fails.
I used same code as your sample without changing anything in windows forms application in c#, framework 4.0.

i tried to fix it whole day but not success, can you please help me.

Error line:

C#

return info.Invoke(obj, parms);

in ExecuteFunction function

C#

internal static object ExecuteFunction(object obj, object[] parms, string fnName)
{
	Type t = obj.GetType();
	MethodInfo[] infos = t.GetMethods(BindingFlags.NonPublic | BindingFlags.Public | BindingFlags.Instance);
	var c = from pe in infos where pe.Name == fnName select pe;
	foreach (MethodInfo info in c)
	{
		return info.Invoke(obj, parms);
	}
	return null;
}

Exception Message:

Hi,

I had the same issue but found an alternative. The following MSDN Article describes how to print a local report directly to a default printer. IMO it's less complicated and works after some adjustments (I use a List<class> as my DataSet) perfect for me.

[^]Walkthrough: Printing a Local Report without Preview

Hi, same problem, when I try to print multiple times (by pressing button multiple times) work the first but the others no. The code is the same.

Hi, Samer.
I am experiencing the same issue. It will print once, then subsequent prints show the printing dialog - but nothing goes to the printer. I am using your sample code unchanged.
Did you ever get a solution to this?

Thanks,
Gerry

Thanks for the input has helped me a lot. I get an error the second option (Printer Print by default) when I try to print directly to the default printer. Error Microsoft.ReportingServices.Interfaces.CreateAndRegisterStream object type 'can not become the kind' Microsoft.ReportingServices.Interfaces.CreateAndRegisterStream. "I am using Visual Studio 2013 with NetFramework 4.5 appreciate your help.

PrintByPrinter("")
First time success, second time can't print anything

Hi I tested and didn't see any proplem
please send me your code

the program gives me error in method ExecuteFunction in info.Invoke return (obj, parms); when I select print to the default printer

Hi Please send me your code to check it

Hello!
I need help.
I can not understand what use Namespace in you example.

H Please refer to namespace in code
Sincerely

When you print with default printer you just get only one time.
I find the bug:
- A few record (10 times in foreach): you can't print multitimes

C#

for(int i =0 ; i < 10; i++)
              names.AddRange(nms);
          viewer.LocalReport.DataSources.Add(new ReportDataSource("Dataset1", names));

- A lot of (600 times in foreach): no problem.

It's take me 4 hrs to fix. But i can't.
Would you like to hepl me.
Thks.

Would you please Send me your code to see the proplem

Nice work! It's very help me.
During integration your solution in my project i rewrite code as extension class for ReportViewer for simple use.
