I am in need of some help, I'm building a web application that uses the KendoUI, specifically the grid to display data.  I've used the entity framework under a "database first" scenario, this means that the models are created for me for all the tables in my database.  I'm displaying this data in the Kendo grid but I can't edit or delete any of the entries (inline with ajax).  If you delete an item it returns when you regresh the screen and the update button does nothing.  I suspect this is because we have no functions to handle these events.

Is there anyway I can utilise the already created scaffolded controller to do this as it already as an edit and delete function in it.

 Any help would be appreciated.

Hello Allan,

 

 

Multiple runnable samples using the Kendo UI Grid and dataBinding are available here, please take a look as I believe they will help you start the project:

Allan:

This may not be your issue, but I had a similar problem yesterday.  I am just getting started with the Telerik MVC stuff, and I created a grid that would read data (from database-first EF model) but would not add or update.  No errors, just would not do anything.

I tried to add a record to my table manually in SSMS and got an error (Primary key cannot be null) because the primary key on the table ("Id") was not set as an Identity field, which is what I had indented.  I changed the table, updated the EDMX in my project and then the grid worked. I was able to add, edit and delete.

Note that this I used the Kendo grid scaffolding helper in Visual Studio 2015 to do this and did not have to add or change any code manually to make it work.

Good luck.
