   DataTable dt = new DataTable();
   dt.Tables.Add[da];
   dt.Columns.Add("Did");

   if (lblDid.Text == ds.Tables[0].Rows[0]["Did"])
   {

       GridView1.DataSource = da;
       GridView1.DataBind();
   }

What I have tried:

protected void Page_Load(object sender, EventArgs e)
{

if(!IsPostBack)
{

var da=objlinq.Facs.ToList();
DataTable dt = new DataTable();
dt.Tables.Add[da];
dt.Columns.Add("Did");
lblDid.Text = Request.QueryString["Did"].ToString();

if (lblDid.Text == ds.Tables[0].Rows[0]["Did"])
{

GridView1.DataSource = da;
GridView1.DataBind();
}

1. You are using the outcome of ToList(); as index for an array!!!
2. No Tables property for DataTable

Um. That code looks like you are guessing and hoping here:
1) dt is a DataTable, so it doesn't have a Tables property. That's for DataSets instead.
2) Whatever objling.Facs returns, I'm pretty sure it won;t involve a collection of DataTables - so da will be a List of whatever those objects are.
3) Add is a method, not an array, so you need round brackets instead of square ones.
4) Add adds a single item to a collection, AddRange is used to add collections of items to a different collection.

Exactly what you are trying to do here I'm not sure - there are too many conflicting mistakes to be sure - so I'd suggest you take a step back, think about what you are trying to achieve and and start again from the beginning! :laugh:
