Because you base page has stopped calling "OnInit" on it's base page which is "System.Web.UI.Page". So always override it
public class DD_AdmBasePage : System.Web.UI.Page
{
public string LoginUser;
public DD_AdmBasePage()
{
LoginCheck();
}
protected void LoginCheck()
{
if (HttpContext.Current.Session["LoginUser"]!=null)
LoginUser= HttpContext.Current.Session["LoginUser"].ToString();
else
HttpContext.Current.Response.Redirect("~/login.aspx");
}
protected override void OnInit(EventArgs e) {
base.OnInit(e);
}
}

Then you are doing something wrong. See the ASP.NET page life cycle[^] and "Init" is called at the beginning. Can you post the whole base class code ?

My full base page code
namespace DD
{
using System;
using System.Data;

using System.Web;
using System.Web.SessionState;
using System.Web.Security;
using System.Web.UI;

public class DD_AdmBasePage : System.Web.UI.Page
{
private string LoginUser="" ;
public DD_AdmBasePage()
{
LoginCheck();
}
protected string PageName
{
get { return HttpContext.Current.Request.Url.Segments[HttpContext.Current.Request.Url.Segments.Length-1]; }
}
public string LoggedInUser
{
get { return LoginUser; }
}
protected void CheckLogin()
{
if (HttpContext.Current.Session["LoginUser"]!=null)
{
LoginUser= HttpContext.Current.Session["LoginUser"].ToString();
}
else
{
HttpContext.Current.Response.Redirect("~/login.aspx");
}
}
protected override void OnInit(EventArgs e)
{ base.OnInit(e); }
}

Can you show your derived Page ?
Are you using OnInit event in that page?
Thanks and Regards

yes it is like this:
#region Web Form Designer generated code
override protected void OnInit(EventArgs e)
{
InitializeComponent();
base.OnInit(e);
}
private void InitializeComponent()
{
}
#endregion

Seems to be tricky. Can't guess from this also
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
}
Check this

I've got an issue with dropdownlist.
Basically I display a dropdownlist in a gridview.
In the gridview is a certain amount of rows(lets say 9 for example)
Now the dropdownlist should display an order number for each row.
The dropdownlist should also contain all the other order numbers for the other rows so the user can change it to another order.
The probably Im having is that when the user chooses say order number 8 and the row is currently order number 2 then when it updates the database the number 2 is no longer in the database and is therefore no longer an option in the dropdown, but I need it to be.
What logical way is there to display the number of rows in the dropdownlist and still be able to update the database and see all the numbers for the rows after. The dropdownlist should never contain more then the number of rows available.
Hope this makes sense!
Feel free to ask for more of an explanation.
cheers

OK ive got the following code:
foreach (GridViewRow row in GridView1.Rows)
{
dropdown = ((DropDownList)row.FindControl("ddorder"));
count++;
dropdown.DataValueField = count.ToString();
dropdown.DataTextField = count.ToString();
dropdown.Items.Add(dropdown.DataValueField);
for (int count2 = 1; count2 <= GridView1.Rows.Count; count2++)
{
dropdown.Items.Add(new ListItem(count2.ToString(), count2.ToString()));
}
}
but the probably is that I need to set the default value of the dropdownlist to a binded value from a database, how woudl I go about doing that?
thanks

Hi Everyone
I'm writing a web application which has a button(call it "go"), after pressing this button, it has to do some calculations which take some time to be complete, so I want the application to play a "please wait" flash(call it "flash") while it executes, but the flash.play=true; code doesn't help me, the flash starts executing after the application has finished executing, so I tried to do the processing in another thread so that the page will be completed & will be sent to the user, now the "flash" plays properly, but I have another problem, after the execution has been done, I want the user to be redirected to another page, like newpage.aspx, but Response.Redirect("newpage.aspx") generates an error calling "the response is not available in this context." Please help me, what should I do?

This may be the cause
Use
System.Web.HttpContext.Current.Response

One way is to use Ajax.
but if you need the functionality in only this page then no need of Ajax.
Do it at client side instead of server
When user click go button show image in the div tag using javascript.
And at the back you can have the same functionality that yo are doing.
I think this easy to impliment also
Thanks and Regards
Sandeep

DLL file is referred to as an assembly.
An assembly is the set of files that comprise an entire .NET application and, in the typical ASP.NET application example, can consist of one single file, or, in more complex situations, can consist of a number of files.
MSIL Code - MSIL, or Microsoft Intermediate Language, is the intermediate language all .NET applications are compiled down to. That is, when a .NET application is compiled, the high-level code you wrote code in C# or Visual Basic .NET is compiled into the intermediate language MSIL. This MSIL is executed by the Common Language Runtime (CLR) when the program is executed.
Metadata - in addition to the actual application's source code (MSIL), the assembly also contains extra bits of information about versioning, security, deployment, and so on.
