I have two master page the second master page under the first , I try add code as
Code:
Response.Redirect(http://msn.com);
but as if something was not, I using pointer but not go to page from the ground up.
I have very simple validation on the aspx page (highlighting not valid textbox), and it works perfectly. But when I try to work with this page using MasterPage, I've got an error - "Object reference not set to an instance of an object." (with reference to the line "aControl.BackColor=Drawing.Color.White" - underlined).
Here is the code of the content page.
<%@ Page Title="" Language="VB" MasterPageFile="~/MasterPage.master" CodeFile="testValid.aspx.vb" Inherits="testValid" %>

I am calling my pages all images from css file like
background-color: #419fbb;
background-image: url(Resources/images/Background.jpg);
background-repeat: no-repeat;
margin: 0pt;
in my project all css files are in Resources/css folder and all images are in Resources/images folder. while runing the project it get background color from css file but don't display background or any image. stablish the correct path to display image.
i have my NEWS BAR script code in my home Page which inherits from masterpage like this :
<asp:Content ID="content1" runat="server" ContentPlaceHolderID="mainholder" >
I want to read from database where I've stored a image in binary field and display a image.
while (reader.Read())
{
byte[] imgarr = (byte[])reader["file"];
Stream s = new MemoryStream(imgarr);
System.Drawing.Image image = System.Drawing.Image.FromStream(s);
Graphics g = Graphics.FromImage(image);
g.DrawImage(image, new Point(400, 10));
image.Save(Response.OutputStream, ImageFormat.Jpeg);
g.Dispose();
image.Dispose();
}
con.Close();
This piece of code doesn't work:
System.Drawing.Image image = System.Drawing.Image.FromStream(s);
I tried the code from this article. And I got the same mistake " the parameter is not valid ". Maybe I'm not aware of something, some setting in sql server or webconfig or sth else. Anyone else who has experience from fetching images from database? The parameter is not valid is the error message. db table contains data. What am I doing wrong?
i have a master page in a root and some pages in root and works perfectly, but now i need a different folder (secure) and in this folder i have an Admin page but doesnt show icons from master, only the placeholder. If i change the url from .css (url('images/page-bgglare.png') to (url('../images/page-bgglare.png') works the pages inside the folder but doesnt works the pages in root.

I am trying to do some code where a user will be able to upload a .JPG picture from the users computer. I have put the controls and also written the C# code wich in my eyes seems to be correct. What happens in the code is that the uploaded picture will replace the existing "TopHeader.JPG" picture.
However when I run the code after I have choosen a .JPG picture from the desktop on my computer. Nothing happens except of a postback of the page.
I wonder what I can be missing out in order to make this work. (I attach both the HTML code and the C# code, I will be happy to know what I could be missing out)

I have a nested master page that has its own master page. The parent master page has a property defined in its code behind.
Public ReadOnly Property SelectedPage() As String
Get
Return _selectedPage
End Get
End Property
How can I reference the parent master page's property from within either the child master page's code behind Page_Load or aspx template page?
My computer system froze on me, the mouse froze, cntrl-alt-del, did nothing, so I reset it. Did a disk check, and now everything seems fine except for my master Page html code which I was in the middle of editing when it happened. The VB code-behind file is still ok, the designer file still shows ok with all of the controls in it, but I can't get into desgn or source view. It just opens and gives a whole page of hesixecimal code such as as:
00000030 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00000040 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
It just gives me a whole page full of numbers like this. I haven't backed up for a few weeks and so I hope I can get this back.
I have a gridview that shows when something is check out. I would like to only show results from todays date and forward. I have done this in Expression Web but when I tried to use the same code in Visual Studios it doesn't work.

I got a Master page and nested master pages in the subfolders. Top Level Master page Second Level Master page inherited Top Level Master page Third Level Master page inherited Second Level Master page However, changes (i.e. new images & alt. name) that I made in the Top level master page did not apply to the second or third levels. My webpage has a correct front page but not in the sections.
View 4 RepliesIn my ASP.Net web application, I have a base page that implements functionality that spans all pages of the web application and my web pages derive from this base page. Since there is a single master page for the entire website, I don't want to attach the master page in each of the web pages. So I attached the Master page via the basepage's OnPreInit method as follows:
protected override void OnPreInit(EventArgs e)
{
this.MasterPageFile = "~/Site.master";
base.OnPreInit(e);
}
However, when I switch to Designer view, I get the "Master Page Error"; The page has controls that require a Master Page reference, but noe is specified. Correct the problem in Code View.When I run the application, the webpage shows up correctly.What should be done so that the designer shows up correctly without having to go and set the master page explicitly in each of the web pages?
BTW, I am on Visual Studio 2010 and .Net 4.0
Here is my structure of master page.
[MasterPage <- Child Page <- Content Page]
1) In MasterPage,i have ContentPageHolder1
2) In Child Page, i add linkbutton into ContentPageHolder1 and create ContentPageHolder2 section
3) In Content Page, select Child Page as master page and try to load the child page link button from page load event but fail
and Checked the current master page name by using [Master.MasterPageFile], it will return MasterPage.
i've a problem regarding the autocomplete extender in asp.net.
It works fine in all page i do, but NOT in a master page.
And i don't know why !!!

I have been browing forums & googling for a couple of hours this morning, trying to find an answer to what (to me) should be a very simple issue. (I am a Delphi programmer moving somewhat reluctantly to Visual Studio C# , for web apps) I have created the simplest ASP.NET website in Visual Studio, containing a Textbox and a Button. When the website loads, I want Textbox1 to have focus. Simply doing
[Code]....
and this too does not work. However, if I press the Enter key when the webpage is displayed, then focus does move to TextBox1 (and pressing Enter again will fire any code attached to Button1). Surely it cannot be this hard to perform something so simple?
