Hi Guadalupe,
Thanks for using Syncfusion products.
Query: “I am work in a web proyect and when I am using the event on.... I've this error”
From your query, we understand that you are facing issue with ASP LinkButton Click event. We are able to reproduce the reported issue at our end only when we render or bind Click event during the run time of the project. Once stopped the project, we have created new link button with new OnClick server event, we are able to resolve the issue. So kindly bind the OnClick event by generating a new Click event.
For your convenience we have prepared a sample with ASP Link Button above the EJ Grid which can be downloaded from below link
The reported issue will occur when its server side event ae not properly bounded to link button. So kindly ensure that you are binding the click event to link button by creating a new server event instead of existing one.
Regards,
Vignesh Natarajan.
