[Solved] Using Telerik Grid with loosely defined model

[Jonathan]

I've encountered a problem using the Telerik Grid: I have a query I need to connect to the grid but it returns an undetermined number of columns that depend on user input (for instance, I show one column per week of data requested).  Because of this, I cannot create a predefined model to give the grid.  I've tried using dynamic types with ExpandoObjects but this fails because creating bound columns requires type-checking.  Does anyone have a suggestions?  Thanks for your help!

I forgot to mention that my current plan is to hack the source and add another constructor to GridBoundColumn to alleviate this problem but I'd prefer not to do this.  Thanks again for your advice.

Also, it appears that for MVC3, there's a check in the GridBoundColumn constructor for whether or not the Grid Model is a dynamic object.  Would upgrading to MVC3 resolve my problem entirely?
