You can put the LoadControls in Page_Load but with below condition :
If(!IsPostback)
LoadControls()
This will cause the LoadControls to call only at the first loading of the page and not everytime postback occurs.
IsPostBack property is used to check whether the page is getting loaded first time of the postback caused by any control on the page.
Hope this helps.
All the best.
I quit being afraid when my first venture failed and the sky didn't fall down.

I am asking the question in this group. I orginally entered it into the wrong group C#.net.
I am wondering if you can tell me what would be the good items I can drag and drop from the visual studio asp.net 2010 tool kit that would acomplish the following tasks:
1. most of the data would be contained in a datagrid,
2. I would like to have a tab on the top of the webpage where the user can tab to over click the 'next' button to accomplish the following tasks:
*The first tab will:
a. allow the user to have a 'type' ahead feature so they can select what organization they want to work with,
b. there will be a datagrid where the user can check off what suborganizations that are affect,
c. There will be a datepicker so the user can select certain dates, and d. there would be a 'next' button and/or tab on top for the user to go to the next page,
e. On this page, there will be a 'save draft' button. This will not commit the data to the database, but it will save the work entered so far.
f. On this page there will be a restart button. Basically this clear out any data and allow the user to start from the beginning again
*The second tab will:
a. display the data entered on the previous page on the top.
b. there will be alot of rows where the data will be prepopulated, and/or allow the user to enter data.
c. This page will show any errors that the user made.
d. This page will also contain a description of what what kind of data is entered on that row,
e. This page will have a button or tab to update the database.
f. There will be a 'save draft' button. This will not commit the data to the database, but it will save the work entered so far.
g. On this page there will be a restart button. Basically this clear out any data and allow the user to start from the beginning again.
h. The final tab will show summary information of what was just entered.

Hello Everyone,
I am trying to use cookies in Custom Role Provider as sessions are showing null exception...
In my login.aspx I am using
Dim newCookie As HttpCookie = New HttpCookie("AccessRights")
newCookie.Values.Add("AccessRights", accessRights)
newCookie.Expires = #12/31/2012#
Response.Cookies.Add(newCookie)
In GetRolesForUser, I am trying to retrive the information from the cookie
If Not Request.Cookies("accessRights") Is Nothing Then
Dim foo as String = (Request.Cookies("accessRights").Value
End if
But it does not like the syntax. Get " Reference to a non-shared member requires an object reference error.
Please advice whether cookies will work in Custom Role Provider in ASP.NET 2.0

During the web development some time we need to add dynamic controls to a web page. Mostly developer’s face problems with dynamically added controls that they can’t get the event as the page post back.
I was also struggling with this issue and at the end I have found two possible solutions
1:- Add the control on page_Init
private void Page_Init(object sender, System.EventArgs e)
{
if (!IsPostBack)
AddControls();
}
private void Page_Load(object sender, System.EventArgs e)
{
}
private void AddControls()
{
TextBox dynamictextbox = new TextBox();
dynamictextbox.Text = "(Enter some text)";
dynamictextbox.ID = "dynamictextbox";
Button dynamicbutton = new Button();
dynamicbutton.Click += new System.EventHandler(dynamicbutton_Click);
dynamicbutton.Text = "Dynamic Button";
Panel1.Controls.Add(dynamictextbox);
Panel1.Controls.Add(new LiteralControl("<BR>"));
Panel1.Controls.Add(new LiteralControl("<BR>"));
Panel1.Controls.Add(dynamicbutton);
ViewState["controlsadded"] = true;
}
private void dynamicbutton_Click(Object sender, System.EventArgs e)
{
TextBox tb = new TextBox();
tb = (TextBox) (Panel1.FindControl("dynamictextbox"));
Label1.Text = tb.Text;
}
2:-Override method LoadViewState
private void Page_Load(object sender, System.EventArgs e)
{
if (!IsPostBack)
AddControls();
}
protected override void LoadViewState(object savedState)
{
base.LoadViewState(savedState);
if (ViewState["controsladded"] == null)
AddControls();
}
private void AddControls()
{
TextBox dynamictextbox = new TextBox();
dynamictextbox.Text = "(Enter some text)";
dynamictextbox.ID = "dynamictextbox";
Button dynamicbutton = new Button();
dynamicbutton.Click += new System.EventHandler(dynamicbutton_Click);
dynamicbutton.Text = "Dynamic Button";
Panel1.Controls.Add(dynamictextbox);
Panel1.Controls.Add(new LiteralControl("<BR>"));
Panel1.Controls.Add(new LiteralControl("<BR>"));
Panel1.Controls.Add(dynamicbutton);
ViewState["controlsadded"] = true;
}
private void dynamicbutton_Click(Object sender, System.EventArgs e)
{
TextBox tb = new TextBox();
tb = (TextBox) (Panel1.FindControl("dynamictextbox"));
Label1.Text = tb.Text;
}
Hope will work for you

Seeing that you claim this is a solution, if i were you i wouldn't post it as a question but rather write an article on the topic at hand. There's a facility to write articles on CodeProject, try that maybe?

Hi there,
Not sure if this is the right forum or not, but I thought I'd ask away.
Our product is thick client/server architecture. We have created a Web-based interface for our product using ASP.NET which does some basic lookups/field changes. We want to take it a step further and create a custom control within a webpage to show our floor-plan module.
Our thick client is written in C/C++, and I realize that in order to do what we want, we would need to port this code over to something a little more browser friendly.
Question:
What language/tools would give me the ability to:
a) Have a canvas where I can custom draw lines, shapes etc.
b) Get Click, Mouse Move events
.. All within a web-browser?
Any help/links you could provide would be great.
Cheers.
M.

I am going to be designing a new C#.net 2010 web page. i would like to know what designer tools I can use to graphically show what the new webpages will look like. What would you recommend?

Dear All,
I'm pretty good with C# however I can't figure out ASP.NET with C#. It's not the C# bit that gives me headaches but the ASP stuff. I have the following problem.
I've created an ASP website ( not entirely true, I used one of VS2010 templates ) and it's has login functionality. I'm using a Postgresql database in the backend and I can login fine. My Site.Master page got buttons in it, but I want a whole new series of buttons when the user has logged on correctly. I've created a new .aspx site that needs to load with a new Master Page. So I've created a new master page, called Site1.Master. It's pretty much the same as Site.Master but it allows me to use different buttons. But for some reason the login information is not display when this new page is loaded. Only after I hit 'F5' on my keyboard ( refresh ) it will show the info and the page works properly.
Site.Master :
<%@ Master Language="C#" AutoEventWireup="true" CodeBehind="Site.master.cs" Inherits="Urenboeken.SiteMaster" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

And my new .aspx file :

CodeBehind="Time.aspx.cs" Inherits="Urenboeken.Account.Time" %>
<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
</asp:Content>
I load my new .aspx file form the login.aspx when the user is logged on correctly.
public partial class Login : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
this.LoginUser.LoggedIn += LoginUser_LoggedIn;
}
void LoginUser_LoggedIn(object sender, EventArgs e)
{
Server.Transfer("Time.aspx", true);
}
}
Can someone tell me what I am doing wrong. Or am I going about it in a very wrong way to accomplish what I want. I hope someone can help out.
Kind regards,

Often, when a problem is "fixed" by a browser refresh, it's because of caching (in the browser or in the proxy). If the "new" page has the same name as the old page and the timestamp of the aspx itself hasn't changed (like it has a new master or CSS or something else external to it), the browser will just say to itself "I already have this in my cache. Not gonna bother downloading another copy."
Yeah, okay, it's doing a HEAD before a GET, and if the HEAD isn't different from the last HEAD it got, it won't do anything. But that's a boring way to put it.

I suspect that the issue is with the Server.Transfer - try swapping it out for a Response.Redirect..
Server.Transfer only (IIRC) changes the "context" on the server, so as far as the server's concerned, you're on that page, but as far as the client is concerned, you're still on the original page. Response.Redirect should keep the browser end in check too.
C# has already designed away most of the tedium of C++.

Richard,
Thank you for your reply. Response.Redirect fixed the problem. And also many thanks to GenJerDan for explaining to me what caused the issue in the first place.
Kind regards,

I need some clever regular expression writing in IIS7 to redirect traffic from one site to another, the pages are similar in structure but information needs re-writing.
Here's an example:
http://www.mysite.com/manufacturers/Name_of_Manufacturer_6828/Name_OF_Product_43146.htm
needs to be structured as the following
http://www.newsite.co.in/free-msds-download/name-of-manufacturer/name-of-product/
Here's what needs changing:
1). Only Alpha, Numeric and hyphen's allowed.
2). Change '_' to '-'.
3). Remove the '_NUMBER' directly after the manufacturer name and before the '/'.
4). Remove the '_NUMBER' directly after the product name and before the '.htm'.
5). Remove the '.htm' and replace with a '/'.
It needs writing into the code below please as a permanent 301 redirect:

Well, your issue can be done by architets of database and software developement, in general view it can be done by 2 centralized databases, first database which is online and second is setup in any server and whenever user lose internet connection applaiction should do CRUD data on server, when internet connection is avaliable all data from local server should transfer on online database.
