Hi I have question about export. I am using datagrid encapsulated in Control and i need set datasource while Control is rendered.

example in Control class :

public function render(){
....
$this["datagrid"]->setDataSource($this->datasource);
};

Everythink is ok, but if I try use CSVExport datagrid throws Ublaboo\DataGrid\Exception\DataGridException You have to set a data source first

I thought datasource needed while datagrid rendered.

Thank you. Milan
