Newbie to ASP.net. Programming in C#.I'm querying a SQL database and displaying the results in a gridview. The results can be many records so I need to provide the facility to scroll vertically and horizontally. To display the headers when scrolling I have implemented ( in my asp code) the headers in another table and the data is in another table. I see now I cannot align the column headers with the table data.Appreciate any help to fix this issue. ( What I need is a similar to the freeze function in excel where you can freeze the header while scrolling horizontally and vertically)If this method is not a good one to display headers with data please suggest another methodHere is my ASP code.
<div id="divProjectTableHeaderFullDetail" runat="server" style="background-color: #993300;
height: 40px; width: 770px; margin: 0; padding: 0 ; " >
<table style="font-family: Arial; font-size: 10pt; color: white;" cellspacing="0"

let us say 'default.htm' (.aspx is not possible due to whatever reason) is "calling" 'start.aspx' as following:
<a href="start.aspx"></a>
now i would like to have a method in 'start.aspx' letting me know, from which page 'start.aspx' had been "called" (in my sample this would be 'default.htm'). what would the c#-code look like?

I have a panel inside an update panel. The panel has a scrollbar. When a control inside the panel is clicked, the scrollbar resets, scrolling the panel back to the top. Is there a simple way to preserve the scrolling position of a panel inside and update panel when a postback happens from inside that panel?

I have problem with user control: MyCollection : UserControl
MyCollection contains:
[code]....
Works fine unless I register event for some button:
button1.Click += ...
When click on button, nothing happens - page does postback, refresh but event handler method is not executed. Generated HTML is bit strange. Every page control has correctly generated ClientID including parent container ID.
Button in this collection MyCollection has odd ClientID - itemsAddresses$button1

I'm having trouble with an image button I create via c# in an event causing page validation to occur on postback. The CausesValidation attribute is set to false at time of creation in the event. I also wire up the Click event in the page_init with postback so not to loose the event handler if the page posts another way. Here is the code I'm using in the click event of a Button. I've also tried to enable and disable viewstate for the button with no luck. What am I missing here that continues to fire page validation in the Click of this imagebutton?

I have written some code using jQuery to use Ajax to get data from another WebForm, and it works fine. I'm copying the code to another project, but it won't work properly. When a class member is clicked, it will give me the ProductID that I have concatenated onto the input ID, but it never alerts the data from the $.get. The test page (/Products/Ajax/Default.aspx) that I have set up simply returns the text "TESTING...". I installed Web Development Helper in IE, and it shows that the request is getting to the test page and that the status is 200 with my correct return text. However, jQuery refreshes my calling page before it will ever show me the data that I'm asking for. Below are the code snippets from my page.Please let me know if there are other code blocks that you need to see.
<script type="text/javascript">
$(document).ready(function() {
$(".addtocart_a").click(function() {

I have a page with three tables, three charts and some other stuff. When I scroll up or down on the page it tries to jump to some other places, scrolling is not smooth. After a few minutes I also get this error popup: Error: Sys.WebForms.PageRequestManagerServerErrorException: The underlying connection was closed: An unexpected error occurred on a receive. The same behavior is noted on all pages with charts.

I have a script that runs during the Page_Load() event which checks a database table to make sure that the user is still owns the lock on the page. If they no longer own the lock, I disable all the controls on the page and display an
error message.My thinking was that by disabling all controls during Page_Load() I could prevent any PostBack events from occuring. For example, I have a button on the page called "Save and Quit"

I have alot of code in the page load event as below.
Is it best practice to use (!NotPostBack) and wrap the code in this block or does it depend on the methods etc. I also have code which populates ajax slideshow as well which gets images from database.

I want to open a native SharePoint 2010 page from my application (for example the Edit Properties page of a document) without the need to enter username/password, but instead to authenticate silently (prior or during the page request). is that possible?In other words, i have a windows forms application, i enter a sharepoint document path and i click on a button, this will open up a windows form with a browser control that will navigate to the native "editform.aspx" sharepoint 2010 page for this document.

How is a page kept where the user last clicked, instead of scrolling back to the top?
I have a page of controls, the user scrolls down to three dropdownlists to fill out, but when he clicks the first one, the page always scrolls back to the top, and he must scroll back down to the dropdownlists again.

My ASP.NET form contains a collection of dynamically-created radiobuttons that are created and configured in the Page_Load event handler.
Normally, I process postback data in the Page_Load handler, using the condition:
if (IsPostBack)
However, since the controls that I need to access are created IN the Page_Load handler, the postback data from the previous rendering of the page is lost. To better illustrate the problem, here is an outline of the events as they occur:
1-Page_Load is invoked for the first time
2-An unknown number of radiobuttons are created dynamically
3-The radiobuttons are configured, based on information present on the server
4-The radiobuttons are added to the page's content
5-The user selects an option, and clicks the submit button
6-The Page_Load handler is invoked for the second time
7-The radio-buttons are added dynamically, exactly as before
8-The radio-button that the user checked is seemingly non-existant for processing
It seems like I need to be processing different parts of this in different event handlers. Is there an event that occurs after postback, but while the original radiobuttons are still accessible?
