Of course it thinks that it is a new page. It is.
If you have anything in ViewState, that is already lost when you leave the page. If you wan't to retain any information, you would have to actually send it along from page to page.
Web pages are stateless by nature, meaning that they are not aware of previous pages, only the information that is actually sent to the page. Every request is a completely new page from scratch, even a postback.

How would I send the information along from page to page? Can you give me a sample to look at?

The Users are stored in a database on a mySQL server that uses the PASSWORD() function to encrypt the passes. What would be the best way to authenticate users?
I read about the Forms authetnication offered by the login control. I have to install a membership database on the server using aspnet_regsql
What if my mySQL server already has a table that stores the user information? Can i still use aspnet_regsql?
Let's say I dont wanna use the Forms authentication offered by the login control and I want to write my custom control.

I have made a flash interface that opens web pages I have created in asp.net. The problem I have is that my whole site basically needs session variables to run, and these variables are decided on the opening page, which is now Flash, depending on the users selection.
So I know that Flash variables can be sent using POST. But how do I retrieve these variables through Asp.Net/VB.net?
Thanks.

:|Hi all,
i want to display the page count for the records to display in a page.
i have the total records.
now i want to display the total pages number.for each there will be 10 records.
now if i divide the totalrecords by 10 i may get a float value, but i want to round it to next number ie., if 168/10 = 16.8 i want it to be 17
can anyone help....

System.Math.Ceiling(16.8) = 17
System.Math.Floor(16.8) = 16

You don't need to use float values at all. Use this formula:
pages = (items + pagesize - 1) / pagesize
e.g.
pages = (items + 10 - 1) / 10

I am using a user control to insert some text into one of my asp.net pages.
However I am trying to make the scr="..." dynamic so that it takes the value from a variable which is storing the id from the url. This value is also being used in a database query.
My question is how do i insert a variable (the id from the url) into the <%@ Register...%>, so that i can change the src according to the correct content page?
For example:
<%@ Register TagPrefix="course" TagName="content" Src="course/blue.ascx" %>
But i need something like:
<%@ Register TagPrefix="course" TagName="content" Src="course/" + course_name + ".ascx" %>
where course_code = the id taken from the url
Any help would be much appreciated

I am using the Login control in a contentholder which uses a Master page as its template. But the problem I am having is to get the "Create new Account" hyperlink on the Login page which links to "CreateUser" wizard page.
If I am not using the masterpage, I am able to get the hyperlink to show up. But I want this to work with the Master page.
WEBPAGE code:
<%@ Page Language="C#" MasterPageFile="~/EPay/EPayMasterPage.master" AutoEventWireup="true" CodeFile="PayOnline.aspx.cs" Inherits="EPay_PayOnline" Title="Untitled Page" %>
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<form id="Form1" runat="server" method="post">
<asp:Login ID="Epay_Login" runat="server" CreateUserText="Create a new Account" CreateUserUrl="~/EPay/CreateUser.aspx" RememberMeSet="false" />
</form>
</asp:Content>
MasterPage code where this content holder is placed:
<td align="left" valign="top" width="562">
<b><asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">
</asp:ContentPlaceHolder></b>
</td>
I felt that it was because the Master page was not using Form, I don't know if it is even reasonable.
Plsss help required asap.

If your Master Page contains the form tag marked runat="server" already, then your content page should not contain any form element, so the Content control only contains the Login control in there.

Hello,
We have a need to customize the CreateUserWizard and we put a
DropDownList control in there. And we are filling that DropDownControl
( _drplDealers) in the page_load event of the code behind page on which
the CreatUserWizard control is existing.
This my Page_load event thats filling the drop down and this works fine
I am getting the data.
*******************************************************************************************************
Protected Sub Page_Load(ByVal sender As Object, ByVal e As
System.EventArgs) Handles Me.Load
drplDealerShipID =
CType(CreateUserWizard1.CreateUserStep.ContentTemplateContainer.FindControl("_drplDealers"),
DropDownList)
Dim GetDealers As SqlDataReader = GetGroundingBL.GetDealers()
drplDealerShipID.DataSource = GetDealers
drplDealerShipID.DataValueField = "DealerShipID"
drplDealerShipID.DataTextField = "DealerShipName"
drplDealerShipID.DataBind()
GetDealers.Close()
End Sub
********************************************************************************************************
But in the CreateUserWizard1_CreatedUser event I can't get the selected
value of the _drplDealers
*******************************************************************************************************
Protected Sub CreateUserWizard1_CreatedUser(ByVal sender As Object,
ByVal e As System.EventArgs) Handles CreateUserWizard1.CreatedUser
Dim drplDealerShipID As DropDownList = _
CType(CreateUserWizard1.CreateUserStep.ContentTemplateContainer.FindControl("_drplDealers"),
DropDownList)
Dim dealer As String
dealer = drplDealerShipID.SelectedValue.ToString
dealer = drplDealerShipID.SelectedValue.ToString
End Sub
********************************************************************************************************
I am not sure the way I am trying to acces the dropdown control that
was filled before in the page_load event is right but it doesnt' throw
any error but I always get nothing although if I have selected a value.
Am I missing some thing here?
Thanks

Its my bad and goofy.... I have forgotten to put my Page_load event in "If Page.IsnotPostback condition.
Protected Sub CreateUserWizard1_CreatedUser(ByVal sender As Object,
ByVal e As System.EventArgs) Handles CreateUserWizard1.CreatedUser
Dim drplDealerShipID As DropDownList = _
If Page.NotIsPostback then
CType(CreateUserWizard1.CreateUserStep.ContentTemplateContainer.FindControl("_drplDealers"),
DropDownList)
Dim dealer As String
dealer = drplDealerShipID.SelectedValue.ToString
dealer = drplDealerShipID.SelectedValue.ToString
End if
This works now. Thanks for all of your time who have looked at it.
Thanks

Hi there,
AFAIK, the EnableCaching property only has effect on the datasource returned from the Select method, but not on any output parameter. So IMO, you should manage to cache the output parameter value on your own.

Here are a couple of things that you might need to do:
+ Create an event handler for the client side even onlick of the checkbox button.
+ In the handler, you can get reference to the elements in other columns using the getElementById method, then populate the properties of the elements.
+ To inject the client side script for the check box of each row in the GridView control, you may use the RowDataBound/RowCreated events.
