//se crea un RadGrid vinculado a la lista de festivos.

 

RadGrid rg = new RadGrid();

 

//configuramos el radGrid para que tenga una sola columna

 

GridBoundColumn columnaFestivos = new GridBoundColumn();

"Festivos";

 

 

columnaFestivos.DataField =

Hello Juan,

You should add RadGrid to Page's controls collection before exporting it. Note that this won't affect your page but only the exported file.
