getdata() - where is this to be defined?

[jrl]

I am working with a code snippet from a site
(http://www.gridviewguy.com/ArticleDetails.aspx?articleID=176_Sorting_GridView _Manually!)
as follows:

private void SortGridView(string sortExpression,string direction)
{

// You can cache the DataTable for improving performance

DataTable dt = GetData().Tables[0];

DataView dv = new DataView(dt);

dv.Sort = sortExpression + direction;

GridView1.DataSource = dv;

GridView1.DataBind();

}

But I can't get it to compile (in C#) because it doesn't understand the
GetData() function in the line:
DataTable dt = GetData().Tables[0];

What would I need to include or change to help it understand this line?

How about looking at the GetData() method, the first thing in the
page?

btw, since DataView supports IBindingList for sorting, there may be
alternatives to strings [just for completeness]:

DataTable dt = null; // todo...
IBindingList bl = dt.DefaultView;
ListSortDirection direction = ListSortDirection.Ascending;
PropertyDescriptor property =
TypeDescriptor.GetProperties(bl)["SomeColumn"];
bl.ApplySort(property, direction);
// now use as a data source

Hi,
You need the code for that method. from the code you posted it seems that it
returns a dataset from where you are getting the first table. Most probably
it use DataAdapter.Fill to get data from a database

thank you all who responded, this makes sense now.
