Hi Mike,

I have an open case number for this - "CAS-40329-O7D41C".

You'll be able to see all the detail in there, but I am suggesting there is a problem with the cached graphics mechanism in the UltraExplorerBar control (which seems to be a univeral mechanism across infragistic controls, including the UltraGridExcelExporter). We are seeing the problem, specifically when an UltraExplorerBar group is selected.

internal void AnimateGroupSelection(UltraExplorerBarGroup newSelectedGroup)
(UltraExplorerBar.cs – Line 17485)

(DrawUtility.ReleaseCachedGraphics() is not being called within AnimateGroupSelection which I believe is causing the problem).

In our code, if we select the group .Selected = True we get the error in our main application. If we omit this, the problem goes away.

It took us 3 - 4 days (changeset by changeset in Team Foundation Server) to work this one out.

(I did by the way check the windows handles on a few of our servers where users run the application, and all looked normal. Handles did not go over 600 at any point in the day).

Kind regards,

Andrew

I had a very simular issue.  Created a Win Form application, and getting same type of error using UltraExplorerBar.  Finally gave up and redid form without UltraExplorerBar and all working well.  Would have been nice to see some sort of resolution from Infragistics to this issue.

This issue was recently fixed, so it no longer occurs in the latest service release.

I am getting this same 'parameter is not valid exception in the windows form 2012.1 controls, so it doesn't appear to be a fixed issue.

Stack trace: at System.Drawing.Graphics.GetHdc()    at Infragistics.Win.UltraWinGrid.ExcelExport.UltraGridExcelExporter..ctor()    at Infragistics.Win.UltraWinGrid.ExcelExport.UltraGridExcelExporter..ctor(IContainer container).  This is happening in the InitializeComponent method called from

the constructor when it hits the line:

this.ultraGridExcelExporter1 = new Infragistics.Win.UltraWinGrid.ExcelExport.UltraGridExcelExporter(this.components);

In my application, it doesn't occur when a control is first opened, but only after a series of open/add/edit/view/close/reopen.  We haven't narrowed

down exactly which step(s) causes it, but it is reproducable in our application.

Hi All,

Still getting this issue, but in a new peice of software recently developed it occours everytime on a non-development laptop.

We have made sure that the laptop has the latest .net framework on it, we have re-compiled the software with the latest DLLs as of today and yet I still get this issue on that laptop and that laptop alone. The only thing different on that laptop then all the other computers here is that the laptop is Windows XP.

Googling the error the only thing I can come up with is whatever is calling graphics dll is calling a dispose() method which causes this error. But as this would be within the infragistics dll I cannot check that. Message similar to above copied in below. Is there any more information you need from me?

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

Line 264 is the form designer is

Line 76 is :

InitializeComponent()

That Exception is very vague and can occur for any number of reasons. Have you tried getting the latest service release?

If that doesn't help, can you reproduce the issue in a small sample project and post it here so we can check it out?

Hi,

We are using Infragistics 14.1 WinForms and we are getting this error from production as well.

is there any solution to this?

Details:

Inner Exception:

Parameter is not valid.

   at System.Drawing.Graphics.GetHdc()

   at Infragistics.Win.UltraWinGrid.ExcelExport.UltraGridExcelExporter..ctor()

   at Infragistics.Win.UltraWinGrid.ExcelExport.UltraGridExcelExporter..ctor(IContainer container)

its  also  happened with  me  in this  version  13.1.20131.2124 not  in  exporting  just  in  initializing  in this  generated  code  

 Me.UltraGridExcelExporter1 = New Infragistics.Win.UltraWinGrid.ExcelExport.UltraGridExcelExporter(Me.components)

Where can I get the service Release for 13.1.

Yes, my application use background threads. but we didn't have this issue with the earlier version of infragistics but just this release.
