Datagrid doesnt populate :(

Hello

Im trying to do a simple page with data from my local sql server, and page
just shows up blank...... I created a stored procedure with SELECT * FROM
Employees......

whats wrong?
using System;

using System.Configuration;

using System.Data;

using System.Data.SqlClient;

using System.Web.UI.WebControls;

using System.Web.UI.HtmlControls;

namespace dbtest

{

/// <summary>

/// Summary description for WebForm1.

/// </summary>

public class WebForm1 : System.Web.UI.Page

{

protected System.Web.UI.WebControls.DataGrid DataGrid1;
private void Page_Load(object sender, System.EventArgs e)

{
SqlConnection conn = new
SqlConnection("server=localhost;uid=sa;pwd=;databa se=northwind");

SqlCommand cmd = new SqlCommand("EmployeesList", conn);

cmd.CommandType = CommandType.StoredProcedure;

conn.Open();
DataGrid1.DataSource = cmd.ExecuteReader(Commandbehaviour.CloseConnection );

DataGrid1.DataBind();

// Put user code to initialize the page here

}
#region Web Form Designer generated code

override protected void OnInit(EventArgs e)

{

//

// CODEGEN: This call is required by the ASP.NET Web Form Designer.

//

InitializeComponent();

base.OnInit(e);

}
/// <summary>

/// Required method for Designer support - do not modify

/// the contents of this method with the code editor.

/// </summary>

private void InitializeComponent()

{

this.Load += new System.EventHandler(this.Page_Load);

}

#endregion

}

}



then:

<%@ Page language="c#" Codebehind="Webform1.aspx.cs" AutoEventWireup="false"
Inherits="dbtest.WebForm1" %>

Hi,

First, are you sure the stored procedure returns results?

Second, it might be the case when aspx pages don't get processed (see
http://support.microsoft.com/?kbid=325093). try inserting a Label on the
page and setting its Text property from the code-behind class to see if it's
rendered correctly.

Hope this helps

Have you compiled your code?

I checked your program and if its written exactly as it is in here, it won't
compile because "CommandBehavior" is mispelled "Commandbehaviour". Also
remember that case is important in C#.

When I corrected this and compiled the application, the DataGrid showed all
of the records.

Martin,

It returns 9, im very sure........

something fishy is going on....... i put in Response.Write("test") and
still the page shows up blank......

i put in "test" in the html-part of the page and it shows....... why isnt
Page_Load event triggered?
