Greetings for everybody

I have had problems trying to export data to excel format from a grid with 34 columns, the data volume is 30,000 records aprox, when the query exceds 20,000 records, I get the next error:

Se produjo una excepción de tipo 'System.OutOfMemoryException'.   en System.Collections.Specialized.HybridDictionary.Add(Object key, Object value)

Here are the exporting options:

                        Grid1.ExportSettings.ExportOnlyData = true;
                        Grid1.ExportSettings.IgnorePaging = true;
                        Grid1.ExportSettings.OpenInNewWindow = true;
                        Grid1.MasterTableView.ExportToExcel();

 could someone help me with some ideas?

Thanks

Hi Andres,

I have found the following forum link which discusses a similar issue. Go through it and see what telerik had suggested.
