Updating Grid Using Callback

[LeighHerbert]

I'm somewhat stuck with getting a Grid to update asynchronously.

Using callbacks, I execute the .NET procedure which sets up the Grid's data source as I want it (a DataTable), but getting the Grid to refresh to reflect the new data source is causing me a problem.

A JScript error is thrown when attempting to execute

GridFX.Grid.get_grids().Grid1.refreshData();

saying that the object does not support this property or method.

I guess my question is, after binding a new data source to the grid, is refreshData() the correct clientside call?

If not, what is, and if so, what might I be doing wrong?

Thanks in advance,

Leigh.
