Hi

I use telerik 2018.1.220.40 and now I have problem with error:

System.ArgumentException: Parameter is not valid.
   at System.Drawing.Bitmap..ctor(Int32 width, Int32 height, PixelFormat format)
   at System.Drawing.Bitmap..ctor(Int32 width, Int32 height)

   at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m)
   at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

 

This error occurs several times per day. We need to restart application after this error because it doesn't respond. I don't create any Bitmap manual in my code and when I look at the error's path I think it's good to ask you about the reason of this error. Is it problem with Telerik or should I look for problem in my code?

Hi Sandra,

I have checked for similar issues and I only found an old thread where the same exception occurred. In this case, Windows XP was used but we were unable to determine the exact reason for the exception. What I can suggest is try disabling the animations by adding this in the main form constructor:

Hi,

We put ThemeResolutionService.EnableAnimations = false; and we thought that it works and I was ready to say thank you, but after two weeks this situation occured again. It occurs only on one computer but all computers on production have operating system Windows 7 Embedded.But yesterday we saw also other error connected with OutOfMemory:

It is hard to reproduce this error because it repeats randomly. But is this error connecting with OutOfMemory helpful?

 

Hi Sandra,

The stack trace looks the same so the issues might be connected. However without a clear way to reproduce that I cannot say what is causing it. Please try to isolate the case where this occurs and open a support ticket for this. 

Please note that the stack trace leads to the title bar of the form. Have you applied any customizations to the title bar? If yes you can try removing them and see if the issue still occurs.

Thank you for your understanding.
