Hello! All,
I have created an ASP.Net MVC 4 application for basic CRUD operations by following this article
[^].

After this I have implemented the Kendo UI Grid, the Edit Functionality works great but when I try to delete the row, I'm getting the following error:

Quote:
The parameters dictionary contains a null entry for parameter 'id' of non-nullable type 'System.Int64' for method 'System.Web.Mvc.ActionResult Delete(Int64)' in 'Skydentech.Controllers.EHRController'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter.
Parameter name: parameters

If I remove the Kendo Grid and move back to the original stuff it works perfect. How can I implement delete functionality which works with Kendo Grid as well.

Thanks.

Fix the error. It is expecting an id but you aren't giving it one.

hey! RayDev,
I've already specified the Id as a parameter.

Somewhere it is not right. Perhaps refer to http://stackoverflow.com/questions/2500021/the-parameters-dictionary-contains-a-null-entry-for-parameter-how-to-fix

Yes there is simply a null check error. You havespecified but the Id might not be getting assigned with any value in the Kendo grid please debug and check.

Your application attempts to delete an item but it cant pass the id for that item to delete. Try something like new{id=Model.ID} on the delete view. The ID depends on what you named yours in ur application.
