I am looking at using the ExpressionEditor to allow the user to add custom calculated columns - and I would like the user to be able to edit the expression afterwards.
What I would like to do is:
GridViewExpressionColumn col = (GridViewExpressionColumn)this.GridView.Columns[activeColumnName];
window.ExpressionEditor.Expression = col.Expression;
but of course ExpressionEditor.Expression is read only; and col.Expression.ToString() does not return the right format. Is there a way to do this directly, or do I have to do something like maintain a separate dictionary of expression text?
Also - is the documentation for ExpressionEditor available yet? There are posts from a while back saying it will be available soon, but I do not see it.
