I'm using visual studio 2010 asp.net website.
I made an aspx. page called forgetpassword.aspx and added a button with the codes
protected void Button1_Click(object sender, EventArgs e)
{
Response.Redirect("company.aspx");
}
I even tried:
protected void Button1_Click(object sender, EventArgs e)
{
Response.Redirect("company.aspx", true);
}
However, the page remains the same, the button is unable to redirect to company.aspx. I suspect there could be something wrong with my master page, but I am not sure. Please advise!
Here is my master page:
<%# Master Language="C#" AutoEventWireup="true" CodeFile="Master.master.cs" Inherits="Master" %>

Here is the source view (html) of my forgetpassword.aspx page:
<%# Page Title="" Language="C#" MasterPageFile="~/Master.master" AutoEventWireup="true" CodeFile="forgetpassword.aspx.cs" Inherits="_Default" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" />
</asp:Content>
You might need to specify the path, as the way shown in MasterPageFile="~/Master.master".
Response.Redirect("~/company.aspx");
EDIT
You need to use same ContentPlaceHolder ID across all the files, by default it is MainContent.
<asp:ContentPlaceHolder id="MainContent" runat="server">
</asp:ContentPlaceHolder>
And also make sure to place your Button inside a form.
<form action="/" method="post" runat="server">
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" />
</form>
Now the redirect should work.
redirect should take a url as a parameter however you are only passing a string "company.aspx". Please try this
Response.Redirect(~/(path)/company.aspx);
Replace path with correct file path in your project
If it is just a redirect use
PostBackUrl="company.aspx"
like
<asp:Button ID="Button1" runat="server" Text="Button" PostBackUrl="company.aspx"/>
This will avoid need of calling event from server side.
Try this
protected void Button1_Click(object sender, EventArgs e)
{
if (Response.IsClientConnected)
{
// If still connected, redirect
// to another page.
Response.Redirect("company.aspx", false);
}
}

I want to popup a calendar control when a textbox is focused. Everything is working except the calendar control is not showing up.
The code:
<%# Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">

<script src="https://code.jquery.com/jquery-latest.js"></script>
<script type="text/javascript">
$(document).ready(function () {
$('#txt_date').datepicker();
})
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:TextBox ID="txt_date" Class="txt_date" runat="server"></asp:TextBox>
</div>
</form>
</body>
</html>
you also need to include JqueryUI
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">

<link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">

<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
<script> <--This is path to jqueryUI
$( function() {

} );
</script>
</head>

I have an ASP.NET project whose page starts with:
<head runat="server">
<meta charset="utf-8">
<title>Online SMS Choose</title>
<link rel="stylesheet" href="//code.jquery.com/ui/1.10.4/themes/smoothness/jquery-ui.css">
<link id="Link1" rel="stylesheet" runat="server" media="screen" href="~/css/tableStyle.css" />
<link id="Link2" rel="stylesheet" runat="server" media="screen" href="~/css/LoadingStyle.css" />
<link id="Link3" rel="stylesheet" runat="server" media="screen" href="~/css/selectStyle.css" />
<script src="//code.jquery.com/jquery-1.9.1.js"></script>
<script src="//code.jquery.com/ui/1.10.4/jquery-ui.js"></script>
<link rel="stylesheet" href="/resources/demos/style.css">
<script>
$(function () {
$("#tabs").tabs();
});
$(function () {
$("#datepicker").datepicker();
});
</script>
</head>
Then my manager told me that I have to merge that project with another one. She gave me the code of the other project. That code doesn't have a head tag in it, but it has this at the start of the page:
<%# Page Title="Service Categories" Language="C#" MasterPageFile="~/Site.master"
AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="service._Default" %>
<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">
<script type="text/javascript" src="Scripts/ZeroClipboard.js"></script>
<script type="text/javascript" src="Scripts/main.js"></script>
</asp:Content>
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
<div class="content" id="Content">
Where do I put the <head> tag in this new project?
The first code snippet you provided is standard HTML markup and the second is ASP.NET markup as I am sure you are aware.
You can combine both of them in the following manner:
<%# Page Title="Service Categories" Language="C#" MasterPageFile="~/Site.master"
AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="service._Default" %>
<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">
<script type="text/javascript" src="Scripts/ZeroClipboard.js"></script>
<script type="text/javascript" src="Scripts/main.js"></script>
<title>Online SMS Choose</title>
<link rel="stylesheet" href="//code.jquery.com/ui/1.10.4/themes/smoothness/jquery-ui.css">
<link id="Link1" rel="stylesheet" runat="server" media="screen" href="~/css/tableStyle.css" />
<link id="Link2" rel="stylesheet" runat="server" media="screen" href="~/css/LoadingStyle.css" />
<link id="Link3" rel="stylesheet" runat="server" media="screen" href="~/css/selectStyle.css" />
<script src="//code.jquery.com/jquery-1.9.1.js"></script>
<script src="//code.jquery.com/ui/1.10.4/jquery-ui.js"></script>
<link rel="stylesheet" href="/resources/demos/style.css">
<script>
$(function () {
$("#tabs").tabs();
});
$(function () {
$("#datepicker").datepicker();
});
</script>
</asp:Content>
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
<div class="content" id="Content">
........
You have already a head section in there:
<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">
<script type="text/javascript" src="Scripts/ZeroClipboard.js"></script>
<script type="text/javascript" src="Scripts/main.js"></script>
</asp:Content>
check your project for files, which put content into this PlaceHolder. If you want to define a <head> wrap it around this content placeholder. But then you need to check the contents of the other files and refactor it, so you do not define a head tag inside a head tag.
<!DOCTYPE html>
<html>
<head runat="server">
<title></title>
<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">
<script type="text/javascript" src="Scripts/ZeroClipboard.js"></script>
<script type="text/javascript" src="Scripts/main.js"></script>
</asp:Content>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
<div class="content" id="Content">
// ...
</div>
</asp:ContentPlaceHolder>
</div>
</form>
</body>
</html>
You can place the <head runat="server"></head> above the content..
Wich file are you supposed to put in the other?
One is using a masterpagefile and the other isn't.
I have a Jquery SooperFish Menu in my master page.Onclick on any SubMenu option it is reloading the Menu. Is there any way to restict reloading Menu every time in Child Page?
To decrease the Database lookups.

It looks as if the onClick postback, if you're writing it yourself (JS) add:
return false;
at the end-
onClick="doSomething();return false;"
Unless you are using UpatePanel's or another AJAX framework, each post-back is a new HTTP request, meaning the menu has to reload because the page is reloaded.
You have several options for caching, search SO or take a look at the link below to get started:

I have two master pages and a content page. On my local machine this code works, but once I uploaded to the server I got the following error:

{
this.Master.Master.DivWidth = 955;
}
Again this works in Visual Studio using the built in web server but delpoying to the production server running IIS6 I get that error stated above.
Any ideas?
public int DivWidth { get; set; }
Does this actually get implemented?
Ok, here is the thing, this works sometimes and then when I add another property or recompile it would give me an error. it turns out it is compiler issue. To get around the issue, I had to create a App_Code directory under the root and made a class. When I get the error telling me there is no DivWidth defined, I simple make a code change in the class I created and the site compiles in the proper order. It took opening a case with MS, who was not very helpful, for me to find this workaround. Hope this helps someone else who runs into this strange issue.
this worked for me:
<%# MasterType VirtualPath="~/MasterPage.master" %>
in .aspx file
Someone can explain this error?

I Think this is a bug of visual studio 2010 in design view. I'not using any event to manipulate session object in the method OnInt(). The "PlaceHolderTopo" is an placeholder in the web user control Topo.ascx. It's work normaly. I Don't have any code inside the content place holder in the page tha inherits from the master page and get this error.
Below is the code of the masterpage:

You have a bug in your Rodape control at design time.
When you open your page in Design view, it creates an instance of your custom control in Visual Studio's process. Since your website is not actually running, the code in your control is probably accessing some static member which hasn't been initialized.
You should launch a second copy of Visual Studio, attach its debugger to the first copy, set Break on All Exceptions from the Debug menu, and find your bug.
