I'm new in LINQ & filling GridView through LINQ. Please see my code :

C#

SqlConnection connection = new SqlConnection(ConfigurationManager.AppSettings["mas"]);
    DataSet ds = new DataSet();
    string Query = string.Empty;

 private void Bind_LINQ_To_DataSet()
    {
        Query = "select * from dbo.Movie";
        SqlDataAdapter da = new SqlDataAdapter(Query, connection);
        da.Fill(ds, "dbo.Movie");
        var tbl = from p in ds.Tables["dbo.Movie"].AsEnumerable()
                  where p.Field<int>("ID") == Convert.ToInt32(TextBox1.Text)
                  select p;
            GridView1.Visible = true;
            GridView1.DataSource = tbl;
            GridView1.DataBind();
    }

    protected void Button1_Click(object sender, EventArgs e)
    {
        Bind_LINQ_To_DataSet();
    }

My GridVIew comes empty. Any suggestion really appreciate.

That means the LINQ is not correct.

2 solutions

Solution 1

C#

Query = "select * from dbo.Movie";
        SqlDataAdapter da = new SqlDataAdapter(Query, connection);
        da.Fill(ds, "dbo.Movie");
        var tbl = from p in ds.Tables["dbo.Movie"].AsEnumerable()
                  where p.Field<int>("ID") == Convert.ToInt32(TextBox1.Text)
                  select new p;
            GridView1.Visible = true;
            GridView1.DataSource = tbl.Tabels[0].DefaultView;
            GridView1.DataBind();

or

C#

DataTable table = (DataTable)Session["Save"];
var query = from c in table.AsEnumerable()

select new { c.Week,c.Person,c.Guess,c.Actual};
GridView2.DataSource = query;

GridView2.DataBind();

May be you can try like this and bind the datatable to the Gridview datasource.

C#

DataTable movie = ds.Tables["dbo.Movie"];

IEnumerable<DataRow> query =
                  from movie in movie.AsEnumerable()
                  where movie.Field<int>("ID") == Convert.ToInt32(TextBox1.Text)
                  select movie;

// Create a table from the query.
DataTable boundTable = query.CopyToDataTable<DataRow>();
GridView1.Visible = true;
GridView1.DataSource = boundTable ;
GridView1.DataBind();
</datarow></int></datarow>
