Error while using html controls

Guest

Hello,
I am developing an asp.net website. I have a web fomr say'
webform1.aspx' having two input button html controls. When I click on
'button1' a message appears. Following code is executed o client side

button1_click( )
{
document.webform1.submit( );
}

and on server side the message is assigned th a label in page_load method.

When a user clicks on other control, the page is redirected to other webform
say' webform2.aspx'.

The problem is as follows -

Now when I click on 'button1' for the first time, I get the message printed
on the label.Then when I click on 'button2', webform2.aspx is also displayed
but now if I click the 'Back' menu of the browser, I again get
'webform1.aspx'. Now if I click on 'button1' again then instead of displaying
text message on the label the page redirects to Webform2.aspx'.

Can any one help me to solve the problem

Thanks,
Sushi

Post the code that you're using to set the label when button1 is clicked and
the code that you are using to redirect the client when button2 is clicked.

Code for webform1.aspx.cs

using System.Web;

namespace WebApplication1.Namespace
{
/// <summary>

/// </summary>
public class WebForm1 : System.Web.UI.Page
{
protected System.Web.UI.HtmlControls.HtmlInputButton btn2;
protected System.Web.UI.WebControls.Label Label1;

private void Page_Load(object sender, System.EventArgs e)
{
string operation = Request.Params["operation"];
if( operation != null )
{
if( operation.ToLower( ) == "btn1" )
{
Label1.Text = "hi";
}
}
}

#region Web Form Designer generated code
override protected void OnInit(EventArgs e)
{ InitializeComponent();
base.OnInit(e);
}

private void InitializeComponent()
{
this.btn2.ServerClick += new
System.EventHandler(this.btn2_ServerClick);
this.Load += new System.EventHandler(this.Page_Load);

}
#endregion

private void btn2_ServerClick(object sender, System.EventArgs e)
{
Response.Redirect("WebForm2.aspx");
}
}
}


Webform2.aspx is any normal aspx page.
