Hi Boris,
thank you for your quick response, it is very much appreciated.

We are using 11.2.20112.1010, the unsigned, version free assemblies.

Here is a copy of the calls:

using (MemoryStream ms = new MemoryStream(Encoding.Default.GetBytes(_displayLayoutXml)))
{
    try
    {
        grdResults.DisplayLayout.LoadFromXml(ms);
    }
    catch (Exception ex)
    {
        Debug.Print(ex.ToString());
    }
}

using (MemoryStream ms = new MemoryStream())
{
    grdResults.DisplayLayout.SaveAsXml(ms);
    ms.Position = 0;
    using (StreamReader sr = new StreamReader(ms))
    {
        gridLayoutXml = sr.ReadToEnd();
    }
 
}

cheers

Hi Boris,
thank you very much for your efforts.
Unfortunately I am unable to wrap this part of the application in a sample.
But I attached the Xml file that is created by saving the layout as txt.

The problem occurs in line 97, character 20

I am not sure if this is relevant, but I store the result in a SQL database.

gridLayoutXml = sr.ReadToEnd();

so gridLayoutXml is written into a varchar(max) field using Entity Framework.

Let me know if you need further information, I'll be happy to provide what's necessary.

Thanks again,
Andy 

Hello Andy,

Thank you for the attachment. So if you are not able to wrap this part into a sample, I suggest that we work on my sample. Please take a look and make the necessary modifications in order to reproduce this behavior.

Hi Boris,
thanks a lot for the sample.
I modified it so it reproduces the problem.

I now get exactly the same error as in my main application using the DataSet you created.

let me know if you have any questions and best regards
cheers

Hello Andy,

Thank you for the sample provided. I downloaded and ran it but I do not get any exception or error, or a failure of some kind. Could you describe what exactly is the problem here? When I click on the button and execute Test1() method, the application just continues to run as it is the moment before. I got a little confused about this issue here, so a few details would be needed.

Hi Boris,
hmmm... in Form1.cs line 109 there is a Debug.Print statement that, in my case, prints the following exception to the console:

System.Xml.XmlException: Invalid character in the given encoding. Line 260, position 18.

   at System.Xml.XmlTextReaderImpl.Throw(Exception e)

   at System.Xml.XmlTextReaderImpl.Throw(String res, String arg)

I could reproduce this behavior on three machines right now, are you sure you don't get this exception. If not this is indeed pretty strange...

cheers

Hi Mike,

I hope you are doing good.

Thanks a lot for this suggestion... it totally makes sense.
I'll stick to this approach :)

cheers and thanks for this suggestion

Hello,

Thank you for your feedback, please let me know if you have any question or if something comes up.

Hi Boris,
after carefully investigating the video there was one thing that made me look closer.
Actually everything you did was exactly what I did, but while comparing the outputs I found a slight difference. I had a decoder fallback operation in my output, you didn't.

So I changed
Encoding.Default.GetBytes(displayLayoutAsString)

to
Encoding.UTF32.GetBytes(displayLayoutAsString) 

That seems to do the trick...

I will check with my main application but I am optimistic that this will fix the problem.

I am deeply sorry for troubling you with this problem, but I appreciated you help very much.
That again was a perfect sample for great support! Keep it up :)

So thank you very much Boris and have a great weekend,
best regards
Andy
