Question

The problem is getting data in my dataGridView from my webservice. When i invoke the getList method from the webservice i get the right xml code.
This is my code:
web service:

[WebMethod]
    public DataSet getList()
    {
        SqlConnection connection = new SqlConnection();
        connection.ConnectionString = "server=localhost;" +
                                   "Trusted_Connection=yes;" +
                                   "database=oving1; " +
                                   "connection timeout=30";
        string select = "select * from Person";
        SqlDataAdapter da = new SqlDataAdapter(select, connection);
        DataSet ds = new DataSet();

        da.Fill(ds, "Person");
        return (ds);
    }

form:

    private void button1_Click(object sender, EventArgs e)
    {

        Service1 webService = new Service1();
        DataSet ds = webService.getList();
        dataGridView1.DataSource = ds;


    }

Answer 1

You better check this Avoiding DataSet in Web services

To serialize Dataset over WebServices Consuming a DataSet from an XML Web Service

One more thing try to deliver a datatable to grid not dataset :

dataGridView1.DataSource = ds.Tables[0];
