    You should use statement like this : when you use SqlDataAdapter you should fill an dataset with Fill Method then set the DataSource Properties Of GridView

        SqlCommand cmd = new SqlCommand("SELECT [Task_temp_name], [Task_templatesID] FROM     [Task_templates]", con);
        SqlDataAdapter sda = new SqlDataAdapter(cmd);
        DataTable dt = new DataTable();
        sda.Fill(dt);
        GridView1.DataSource = dt;
        GridView1.DataBind();
        con.Close();

    The ASP.NET Core Configuration system reads the ConnectionString key. For local development, it gets the connection string from the appsettings.json file: "ConnectionStrings": { "MvcMovieContext": "Server=(localdb)\\mssqllocaldb;Database=MvcMovieContext-2;Trusted_Connection=True;MultipleActiveResultSets=true" }

    You have missed Fill method to fill your your dataset that is why i think you are not able to display gridview.

    Fill Method is very Improtant method Bcoz whatever your query is returning that should be filled into your dataset & then that dataset is binded by your Gridiview Hope this will help you

    protected void Page_Load(object sender, EventArgs e)
    {
            SqlConnection con = new SqlConnection(@"Data Source=(LocalDB)\v11.0;AttachDbFilename=C:\Users\Guillermo\Desktop\HorsensHospital\App_Data\HospitalDB.mdf;Integrated Security=True;Connect Timeout=30");
            con.Open();
            SqlCommand cmd = new SqlCommand("SELECT [Task_temp_name], [Task_templatesID] FROM [Task_templates]", con);
            SqlDataAdapter sda = new SqlDataAdapter(cmd);
            DataSet ds = new DataSet();
            sda.Fill(ds);
            GridView1.DataSource = ds;
            GridView1.DataBind();
            cmd.ExecuteNonQuery();
            con.Close();
    

    }

    Note : You need to create your connection string in Web.Config. Bcoz If you have created your connection string there then you will not need to create that again. Once creating there you will just need to call that from the Web.config

    SqlConnection con = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["ConnectionStringNameFromWebConfig"].ConnectionString);
    

    This is the syntax for calling connection string from web.config

    By default, LocalDB database creates “*.mdf” files in the C:/Users/<user> directory. From the View menu, open SQL Server Object Explorer (SSOX). Right click on the Movie table > View Designer. Note the key icon next to ID. By default, EF will make a property named ID the primary key. Right click on the Movie table > View Data.

    You just assing your empty DataSet to your Gridview's DataSource.

    You need to use .Fill method fo fill your DataSet of SqlDataAdapter. You don't need to use ExecuteNonQuery. This method just executes your query. It doesn't return any data or something as a result.

    Also use using statement to dispose your SqlConnection, SqlCommand and SqlDataAdapter. You don't need to .Close() your database connections and objects when you use it.

    using(SqlConnection con = new SqlConnection(conString))
    using(SqlCommand cmd = con.CreateCommand())
    {
        cmd.CommandText = "SELECT [Task_temp_name], [Task_templatesID] FROM [Task_templates]";
        using(SqlDataAdapter sda = new SqlDataAdapter(cmd))
        {
             DataSet ds = new DataSet();
             sda.Fill(ds);
             GridView1.DataSource = ds;
             GridView1.DataBind();
        }
    }

    If you omit this setting, ADO.NET connects to the default database for the SQL Server instance specified in the Data Source setting. If you omit this setting and include the AttachDbFileName setting for SQL Server Express or LocalDB, the full path to the database file is used as the database name.
