DataSet from GridView is null

Asked by rss2 in Microsoft Visual C#.Net

Tags: c# asp.net visual studio 2005

Hi Experts,

I have a gridview which gets populated. I'm trying to create a dataset from it so I can export the dataset to excel.

When the "XL" button is clicked it calls a function which calls the lines:
DataSet ds = ((DataSet)GridView1.DataSource);
ExportDataSetToExcel(ds, "Book1.xls");

As I step through the code, I notice ds is null.

When I get to populate a datagrid in the ExportdataSetToExcel function, I get this error:
NullReferenceException was unhandled by user code:
Object reference not set to an instance of an object.

.. this occurs on:  
DataGrid dg = new DataGrid();
dg.Datasource = ds.Tables[0]; <--- here

What's going wrong?

Thank you,
rss2
