Are the number of columns predefined?

My suggestion would be to create a DataTable and store it in the viewstate (or session if you need to maintain it cross-page) and add rows to the datatable which will be bound to your gridview.

// DataTable accessor
protected DataTable DT
       return ViewState["DT"] AS DataTable;

// This is roughly drawn up without VS help
// Make sure you check for DT being null if it's possible
// It also doesn't include the initialization for the DT
protected void populateGridView(string x, string y)
   DataRow dr = DT.NewRow();
   dr["x"] = x;
   dr["y"] = y;

// Remember that databinding happens after PreRender event
protected void Page_PreRender(object sender, EventArgs e)
   myGridView.DataSource = DT;

It needs to be done like, Create a datatable, Add object values into the datatable, just bind the datatable.
