I'm very new to .net so please be patient w/me. I'm using C# in VS2005. I have the following in my login.aspx page for the button

<td align="center" colspan="2">
<asp:Button ID="Submitbtn" runat="server" Text="Log In" ValidationGroup="Login1" BackColor="DarkGray" Font-Bold="False" ForeColor="Black"/>

This is the code behind. Somehow when I click on the button, it is not firing the event Submitbtn_click. Can someone please help me? I'm using typed data sets. Thanks in advance...

login.aspx.cs (Code Behind)

using System.Collections;

using LoginTableAdapters;

namespace LoginPage
publicpartialclassWebForm1 : System.Web.UI.Page
protected System.Web.UI.WebControls.TextBox UserName;
protected System.Web.UI.WebControls.RequiredFieldValidator rvUserValidator;
protected System.Web.UI.WebControls.TextBox Password;

private void Page_Load(object sender, System.EventArgs e)


private void InitializeComponent()
this.Submitbtn.Click += new System.EventHandler(this.Submitbtn_Click);
this.Load += new System.EventHandler(this.Page_Load);

private void Submitbtn_Click(object sender, System.EventArgs e)
if (Page.IsValid)
// Create the tblUserTableAdapter
tblUserTableAdapter LoginAdapter = new tblUserTableAdapter();
// Get account information based on parameters entered
Login.tblUserDataTable Accounts =
LoginAdapter.GetDataBy("user1", "password");
// Bind the order results to the GridView
this.GridView1.DataSource = Accounts;

protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)


How do you determine if Page.IsValid is true?

Hello everyone,

I actually got it to work. It used the FindControl method and converted it to a text box.
