Hello,

wrong assemblies was what I expected to, but we got a list of the GAC and a list of the files in the folder our application was deployed to via Click Once. Both seemed to be ok.
In order to get more detailed information we will write the loaded assemblies to the a log file and check those. Maybe it is more conclusive.

Multiple threads as a source can be excluded. We are not using multithreading where this error occurs and it currently only effects three specific computers. Reproducable, whenever a layout is assigned.

Hi,

Can you reproduce this issue in a small sample project?

Was this code working at some point and now it's not? Or has it never worked?

Are you saving anything else to this stream beside the grid layout? Can you post the code you are using to save the layout to the stream?

What are the data types of the columns in your grid?

Hi Mike,

The code i am using is working in one grid and is not working for one of the other grid in my project.

Is there any property or setting of column/bands or datatype of column which may result in this exception ?

Datatype of column include all Int64,Int32,Double,DateTime,String

I am just saving the layout to this stream and nothing else.Below is the code I am using to Load and Save the Layout.

I am saving Layout to an XML and the saving it in database

myGrid.DisplayLayout.SaveAsXml(fileName, PropertyCategories.All);

Then at load i am deserializing it to stream 

string

App.SystemSerializer.DeserializeDefaults(sessionType, out

defXml);

MemoryStream strLayout = new MemoryStream(byteArray);  

if (strLayout != null)

{

uGrdResults.DisplayLayout.LoadFromXml(strLayout);

strLayout.Close();

}

Please let me know if anything wrong is there.

I will work on a project to replicate this issue.

Thanks for reply any help is much appreciated.

Hi Mike,

Thanks for reply.

I tried using streamReader/Writer but it still does'n work. :(

Hi Mike,

Thanks for your help.

For now we are looking for some other options to restore the layout.

Thanks

Rooma

Well, if you can post a sample that demonstrates that, I would be happy to take a look at it. But without a sample, I'm afraid I have no idea why it's not working. Maybe your database is somehow altering the text for some reason.

Yes, I replaced my code with code given by you.

And still getting same exception.

Are you getting the same exception?

Are you sure you are not using the encoder any more?
