Hi Paul,

Entity State may appear if you are using auto generated columns and entity framework. Is this the case? The grid creates a column for every public property of your model which includes EntityState for EF models. The solution is to define the columns which the grid must display:

<%= Html.Telerik().Grid()
.Columns(columns =>
{
columns.Bound(c => c.Name);
columns.Bound(c => c.ID);
})
%>

Now I understand...

Once you "take control" of the columns by using the ".Columns()" construct, you are in effect telling the grid to stop auto-generating and use what you tell it to use in the statements that follow.

I [rather stupidly] thought that you were setting attributes of the columns that the grid had already decided to render.

It isn't all that clear that this is what happens though - I'm quite sure I'm not the first to get caught like this or that I will be the last !...

BUT - Thanks for all your help & support - its greatly appreciated especially since the MVC stuff is "just so cheap" ;-)

Actually; it would be good to still allow auto-generation with Data Annotations and the like, but provide a further mechanism to "hide" the auto-generated columns from the grid without taking full control over the columns and completely losing the auto-generate feature. Next release perhaps ?... :-)

Paul.
