This may be way out there, but figure it can't hurt to ask.

We are using MVC Razor Grid, and have a Master/Detail grid working. However, is there any way to dynamically (ondatabound, etc) set the Detail grid for a particular Master Row as Editable(false)? The Master grid contains a year column, and we want the Details grids to only be editable if the year is the current year or later. Can the Grid's Editable attribute be set by jquery?

Hello Michael,

Yes, the editable option can be modified using the setOptions method, as shown in this example.

I understand that one, and did find it inthe Kendo documentation. Unfortunately, our app is too big to allow for us to migrate to Kendo (not to mention the red tape we have to go through, here!), at this time... The app was built on ASP.NET MVC, build 2012.1.214. Is there any option for similar functionality with the MVC Raxor grid?

I apologize for the misunderstanding Michael.

Changing the editable options at run-time is unsupported in the Telerik Extensions for ASP.NET MVC. You can try achieving similar behavior using the Grid's edit event handler instead. Once the even it triggered you can check the dates and if the conditions are met - call the cancelChanges method. 

I also would like to remind you that as of June 2013 the product is no longer supported and that migrating to Kendo UI is highly recommended.
