Maintaining cell state in the Telerik RadGridView for Silverlight

Question

I have a RadGridView in which one of the columns contains only buttons.

Depending on the value of a boolean variable linked to a specific record in the grid, I enable or disable the cell containing the button. This is how I achieve this:

foreach (Item item in this.radGridView.Items)
{
    row = this.radGridView.ItemContainerGenerator.ContainerFromItem(item) as GridViewRow;

    if (row != null)
    {
        cell = (from c in row.Cells
                where c.Column.UniqueName == "buttonCol"
                select c).FirstOrDefault();
        if (cell != null)
        {
            if (item.buttonEnabled)
            {
                cell.IsEnabled = true;
            }
            else
            {
                cell.IsEnabled = false;
            }
        }
    }
}

The problem is since my grid has horizontal and vertical scrollbars and since I am using row and column virtualization, the state of the cells containing the button that are not shown is lost. Disabling virtualization is not a solution in my case since I have a lot of data in my grid.

I wonder which event of the RadGridView would be the best to invoke my function that set the state of the button cells whenever shown values change?
