How do you delete a row from a DataGrid using a DataTable?

[Mark Jones]

I'm trying to delete a row from a DataGrid using a ButtonColumn with
CommandName="Delete" by deleting the row in the underlying DataTable
datasource, but it doesn't seem to be working at the minute. I'm using
session data to fill the DataTable which subsequently fills the DataGrid.
The code is as follows (with "dgBasket" as the DataGrid):

private void dgBasket_DeleteCommand(object source,
System.Web.UI.WebControls.DataGridCommandEventArgs e)

{

int rowToDelete = e.Item.ItemIndex;
DataTable myTable = (DataTable) Session["Basket"];

DataRowCollection myRows = myTable.Rows;

DataRow thisRow = myTable.Rows.Find(rowToDelete);

thisRow.Delete();

Session["Basket"] = myTable;

dgBasket.DataSource = myTable;

dgBasket.EditItemIndex = -1;

dgBasket.DataKeyField = "Product";

dgBasket.DataBind();

}

The page builds successully with no errors but nothing happens when I press
one of the delete buttons- the page reloads but the info doesn't delete.
Does anyone know where I'm going wrong?
