Hi Vignesh and thx for your sample.I found the problem !! it is just like the bug i found with your combobox component (issue 136550). It's working with Chrome, Firefox, but it's not working with Edge :It says :INCORRECT REQUEST. The server could not process the request because the syntax is not valid.Regards,Fred.

Hi Vignesh,I'm not using combobox in my grid and it will be difficult to isolate a sample of my code since it is encapsulated with WCF calls. I'll try to make a sample if we can't resolve the problem.I have a problem with Edge, it is very weird.I tried your sample with all browsers and it works good. But when i try with Edge, see the result in the screenshot in attched file.All rows and cells are empty !I'm using Microsoft Edge 41.16299.371.0EdgeHTML 16.16299On Windows 10 and Visual Studio 2017 v15.7.0 preview 4.0.Can you understand what is happening ?Attachment: 20180425_16h38_58_dee69c20.rar

Hi Frédéric,  
 
 
Thanks for the update. 
 
 
We have analyzed your issue (cell are empty and blank rows) and we suspect that reported issue occur due to camelCase issue which occur in ASP.NET core. When Camel case issue occurs, column names will be changed to small letters.  
For example. If the column name is CustomerID, while returning for the server the name will be changed as customerId. So the issue occur.  
 
To overcome from this issue we suggest you to follow the below code in the your startup.cs project  
  




public void ConfigureServices(IServiceCollection services)  
        {  
            // Add framework services.  
            ...  
  
            services.AddMvc()  
            .AddJsonOptions(x =>  
            {  
                x.SerializerSettings.ContractResolver = null;  
            });  
                   ...  
        }  
  
  
  
    
  
Else refer to the following document to solve casing problem and also mention field values in camelcase.

Hi Frédéric, 
 
Query: “Since latest versions of your ASP.NET Core JS 1 (16.3.0.29 i there is a problem with "batchSave" of the grid.” 
 
From you query and screenshot, we understood that value for myObject is returning as null. As per your suggestion we have upgraded the sample provided (on April 25th 2018) to 16.3.0.29 version. We are not able to reproduce the reported issue at our end.  
 
For your convenience we have attached the upgraded sample

Hi and thank's for your answer.It's very difficult for me to isolate and make a sample with my problem since it is a part of a big project.I have not tested this functionnality since a long time, so i don't know when it did not work anymore.The code is quite simple :

Hi Frédéric, 
 
Thanks for the update. 

For your convenience we have created the sample with the updated code example, we are unable to reproduce the reported issue at our end. Please refer the below link, 

http://www.syncfusion.com/downloads/support/directtrac/general/ze/WebApplication12060554332.zip  

The reported issue(BatchURL method return the value as null) will occur in the below scenario, 


If we use difference datasource model, then the reported issue will occur (i.e.) for grid databinding if you use the dataSource model as “OrderDetails”(for example) then you must use the same dataSource model in the BatchURL method also. Kindly, ensure whether are you using the same model. If not, please use the same model to avoid the reported issue.

Still facing the issue, please get back to us with the following details. 


Please Share the complete grid view and controller page code example.
Please Share the network tab post details.

The provided details will help us to resolve the reported issue as early as possible.
