The objects that are enumerated in my Kendo MVC Grid are of type dynamic:

@(Html.Kendo().Grid<dynamic>()
...

I am using InLine editing.  I am able to specify the editor for each of my fields as described here:

http://www.telerik.com/forums/inline-editing-mode-and-dynamic-object
http://docs.telerik.com/kendo-ui/aspnet-mvc/helpers/grid/editor-templates

I won't reiterate the approach that is described above, but in summary it involves adding a UIHint attribute to fields in the model, and then using EditorTemplateName to identify an editor template for the field (and that editor template refers to the field via the Name() method).  This works.

The problem that I have is that many of my fields need to appear in non-editable columns.  My hope was that I could get the grid to render those fields as is (no editor) by:

a. Omit the UIHint attribute from model properties that would not be editable
b. Not specify an EditorTemplateName for non-editable bound columns
c. Set Editable(false) when defining the model (as below):

.DataSource(d =>
{
     d.Ajax()
        .Model(m =>
         {
             m.Id("Id");
             m.Field("Name", typeof(string)).Editable(false);

However, when I do this the grid fails to load and I see an exception in Fiddler:

[RuntimeBinderException: 'object' does not contain a definition for 'Name']
   CallSite.Target(Closure , CallSite , Object ) +152
   System.Dynamic.UpdateDelegates.UpdateAndExecute1(CallSite site, T0 arg0) +662
   lambda_method(Closure , Object ) +133
   Kendo.Mvc.UI.Html.GridDataCellBuilder`2.AppendCellContent(IHtmlNode td, Object dataItem) +131
   Kendo.Mvc.UI.Html.GridDataCellBuilderBase.CreateCell(Object dataItem) +230

I have many fields and most of them wil be non-editable, so I would rather not, for example, create editor templates for each of them that contain disabled controls.

What is the best way to configure all my non-editable columns in an InLine grid that is bound to dynamic objects?

thanks,
Derek

Hi Derek,

Indeed, you should be able to disable the editing for given field by setting its Editable option to false. However, this, as seems, does not work in the scenario in question as we were able to replicate the error you have described. Fortunately, we manage to address it and the fix will be included in the next internal build. Meanwhile, I have updated your telerik points.
