In my Grid, using a custom PopUp editor, when adding a new record, if the user Presses Cancel, the PopUp closes appropriately but there is a blank record left at the top of my grid.  How do I prevent this from happening? I imagine I have to refresh the dataSource, but from where?

Hello Joe,

In general, when the cancel button is clicked on a new record the Grid should remove the record automatically.

This can be observed in our demo and in the runnable example with custom popup editor as well:

http://demos.telerik.com/aspnet-mvc/grid/editing-popup

I can assume that there is a custom code which is interfering with the editing functionality. If possible provide a fully runnable example reproducing the issue and I will gladly assist. The attached project can be used as a starting point.

Regards,

Hello Felix,

Thank you for the error stack and details provided.

I tried to replicate the pointed faulty behavior. The result could be found in the sample project(attached) that I prepared for the case (ASP.NET MVC).

It includes a Kendo UI Grid with a "PopUp" Edit Mode. Try adding a new record, click on the "Cancel" button, and observe the result.

I hope this example provides the expected result. Feel free to use it as a template or as you decide. If further assistance is needed, try to replicate the described issue in a runnable sample project(could use the attached one for the purpose) and send it back to me in this thread. Once I have it locally will try my best to resolve this one for you.

Looking forward to hearing back from you.

 

Kind Regards,
