System.InvalidOperationException: A circular reference was detected while serializing an object of type 'System.Data.DataView'.

[Alex Jermy]

Hi,

I tried another method to perform CRUD operations on a SQL database using Syncfusion controls, outlined here:

https://www.syncfusion.com/kb/7423/how-to-perform-crud-operations-with-asp-sqldatasource

However I am getting this error message when I try to load the page:

System.InvalidOperationException: A circular reference was detected while serializing an object of type 'System.Data.DataView'.

I have attached an ASP and  code behind file to illustrate the issue.

Thanks,

Alex

Hi Alex,  

 

Thanks for contacting Syncfusion forums.

From your query, we understand that your facing issue while performing CRUD action using sql dataSource. We have tried to download the attachment but it gets redirected to our download, since it is not attached properly. So kindly reattach the documents. In the mean time kindly refer our online demo sample to perform the CRUD operation using SQL dataSource.

After referring the online sample still you are facing issue, kindly reattach the attachments properly.
