Web Forms :: FRAMESET Is Causing Page Load Fire Twice?
Nov 17, 2010
for obvious reasons using master page instead of iframes is good in my view but the current project which is on Framework 1.1 has some some limitations to do any modifications as client is already using some 3rd party controls.Now, the issue i am facing is with page load event which is firing twice. Please see the below html code.
[Code]....
from the above code when eFolderTree.aspx is called with iframe "TreeAppFrame", the "page load" event in eFolderTree.aspx.vb is firing twice. I debugged for the issue and found that this is happening because of iframe "primaryAppFrame" which is calling "SiteFolder/ShowSiteFolderTable.aspx?Site=<%=sSiteId%>". when commenting the page reference "ShowSiteFolderTable.aspx?Site=<%=sSiteId%>" in frame "PrimaryAppFrame", this is working correctly.What else do i need to do, to make sure that page load event fires only once in page "eFolderTree.aspx.vb" ?

I've created a User Control (.ascx), which has a dropdown. When an item is selected, it uses some model classes to pull back a set of data which it then dynamically displays as a list of checkboxes in a panel control.
When I add one to the page, it works very well indeed.
However, when I add another I get this behaviour:
1. Select an item from the first dropdown, the checkboxes appear underneath ok.
2. Select an item from the second dropdown, the new lot of checkboxes appear ok, but the first lot disappear.
It's rather frustrating, they both have different IDs on the page, so they shouldn't interfere with each other should they? There is some Javascript that I've added but I use the Panel.ClientControlID to separate these out (I've already thought of that one).

I have a website where different comapny and users can login. Till now I have not seen any issue on IE 6. But in case of one account, when try to login the website, users are getting security information "This page contains both secure and non-secure items.
I can reproduce the same easily for the same customer but not happening for any other customer. I have "ReportViewer" control (gets rendered as iframes) on the page.
In this scenario, whether user selectes "Yes" or "No" button, the home page with charts loads 30% and other controls remains invisible. Though I see same out in "View source" for this and other customers. We dont change anything much then the data and charts for the users. We use https for this website and has few links with "http" in page. But then this is same for all the users, but it happens only in case of one customer.

We are adding openfire fastpath chat to our site. It will determine and indicate when live chat is available or not and display an appropriate image to indicate the current status and links for each state.
The javascript call hit's a function that is on another box and this function uses document.write to output the html to the page. I know there is a delay because it is making the request to another server and waiting for a result to be returned. The pause here is about a half second, but causes the rest of the page load to be held up.
Has anyone experience a similar issue or offer any tips for getting this to load synchronously somehow. I tried putting this into an aspx ajax panel, but that seemed to cause other issues.

I dynamically add the webcontrol in onInit or onload (page_load). it will cause the second post back and with the ispostback==false;
if first enter the page is no problem. but if I click on the some button. it will trigger postback two times.
first time: ispostback = true.
second time: ispostback = false.
the second time postback caused me headache because all my value has been initialized due to the coding like below:
DataTable _temp;

I need to implement a "preview" functionality where people make changes to a form, click a button and a pop-up window displays the preview while the original form retains the user's changes in the various <textarea's. Right now, the preview is working, but when they come back to the form, their changes are gone, the page has refreshed. How do I prevent the page from refreshing? I need to go to the server to get the URL to the preview page.

I need to know if there is any server-side function/custom-code available to find out the HTML of the entire page which is causing the PostBack.
I don't want to do it using JavaScript/jQuery but instead do it at server side.
A JavaScript workaround that implements it can be found at this link. [URL]
Reason, Why I need it? I am writing some inline javascript in page which performs some vital actions and supposed not to be tampered by user(hacker). So, when a postback occurs, I would like to find out the HTML of entire page (at server) so that I can verify it (I have already generated the hash code for entire HTML while rendering the page to check it on consecutive postbacks) for non-tamering and then process further.
This is the reason why I need a way to find out the HTML of the page causing the PostBack.

I am creating sample application for master page layout, it contain three parts as follows
1. Header
2. Content
3. Footer
and wanted header and footer will be static content in web page.(Content will be scrollable)
For that I have found one solution in HTML (frameset and frame) but I am looking for pure ASP.NET solution.
So question is, Is there any alternative present in ASP.NET?

I have a problem that I can't solve when I load controls dynamically. I have 3 states on a page that I traverse through and I load as many buttons on the page as the page state number + 1. For example, on state 0, I load 1 button, state 2 - 2 buttons, etc. The problem is after I move to a new page state, the button click event(s) of the dynamic buttons will not be wired up and won't fire until the second click of each button.

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 an aspx page that postsback when it should not. there are two text boxes, two listboxes and two buttons on the page. if at any-point the enter key is pressed the first button is given focus and "clicked" resulting in a loss of selection within the listboxes.
How do I disable this? there are tons of tutorials on how to capture the enter button and execute a method but I could find one on how to simply disable the neat "let me grab the first button I find and click it" feature mentioned above.

To find out when there are any exceptions when users are using the system, then the ErrorDetails are being auto-emailed to members on the IT team to help in troubleshooting. The problem is this: I want to find out what page is the user is on when the exception happens, sometimes the stacktrace does not list the aspx page. Does anyone know how to get this information?
