well a webservice wouldn't put the results into a grid - the webservice should return a serialized bit of data. So in the webservice code you could stick the stored procedure results into a datatable and return that from the webservice.
The calling code can then consume that webservice and load the resulting datatable into a grid.

	[WebMethod]
	public DataSet GetData()
	{
		SqlConnection conn = new SqlConnection(connectionString);
		SqlCommand command = new SqlCommand("Stored Procedure Name", conn);
 
		// Add any command parameters here:
		command.Parameters.AddWithValue("@name", "value");
 
		DataSet data = new DataSet();
		SqlDataAdapter da = new SqlDataAdapter(command);
		da.Fill(data);
 
		return data;
	}
 
// and to load into the grid
 
	private void LoadGrid()
	{
		WebService ws = new WebService();
		DataSet data = ws.GetData();
 
		dataGridView1.DataSource = data;
		dataGridView1.DataMember = "table1";
		dataGridView1.DataBind();
	}

I thought a webservice like GetData should have the following parameters:
[WebMethod]
        public static List<Claim> GetData(int startIndex, int maximumRows, string sortExpressions, List<GridFilterExpression> filterExpressions)
        {
?

it should have whatever parameters it needs - mine was just a simple example to show how it could be done. Normally a routine to get some data would include some kind of filtering with parameters - but not always.

ok - I don't think all the code is there - the cs files for the master page & the default page are missing.
Are you getting the error on the line:

setInterval("Service2ns.Service2.GetData(updateGrid)", 1000);
in the pageLoad javascript routine? setInterval is expecting you to pass it another javascript function. You need either call the webservice from code behind.
Or from what it looks like you should change that line to:

setInterval("updateGrid()", 1000);
But I'm not sure how you would pass in the result each time.
