The event fires, the event handler is executed, but the lable doesn't become visible. If I place the button outside of the tab container, it works.
Are there some existing examples of making a DIV or panel visible or not visible based on an ajax event?

I have a web page that I have a media control player on along with other controls in a table.It's a training video, so the controls are not visible.So the user can advance to the next web page,I thought I would have a button control inside an update panel with a time control so that the user had to watch the video and then the button control would appear after the video completed.I'm setting the button update panel to NOT visible and then turning it one when the time control elapses the same amount of time that the video runs.My problem is that when I set the visible property of the update panel to NOT visible it also makes the media player's panel NOT visible too.They are in two different panels.The medial player in a standard panel and the timer control connected witha separate panel that contains the button for the user to proceed. When I set the visible property to "true" the media player runs but the update panel with the button is visible also.

This is the code for the update panel and continue button that is in a separate table cell.I even split the table and so this is in a completely separate table but I still get the same behavior.

View 4 RepliesI have an asyncfileupload control within a panel control. The panel is initially set to visible=false on page load. After a user clicks a button to display the panel contents however, I set the panel to visible and the user can then use the asyncfileupload. The problem however, is it seems much of the javascript associated with the asyncfileupload, does not function properly when the panel containing the upload control is set from invisible to visible. If I set my panel's "visible" property to "true" initially, then it works fine. My javascript error message is as follows:
"Form contains a file input, but is missing method=POST and enctype=multipart/form-data on the form. The file will not be sent."
Basically within my asyncfileupload control, I have the following line:

In this scenario, my "args" variable is always null (when I set my pane's "visible" property to "true" on page load, the args variable DOES contain data. Any idea why switching a panel from visible=false to visible=true, would cause an error like this?

Using VB, VS2010, I have a large image in a panel and want to be able to pop-up panels while hovering over it. This one large image is a picture of a lot of components that I woulld like to treat individually when I hover them. I have done this before by placing a transparent button in another panel that is absoultely positioned over the larger one. I have the button transparent with a border that shows up using hover in css. Everything works fine expcept that the panel does not show itself in the right place when viewiing in the browser window. It shows fine in design view, but shifts over while browsing in the browser. I have tried making all panels absolutely positioned. Still a problem. Is there a better way to put a panel over a panel?

How do I capture other events in an asp.net textbox on a webpage in more of a way in which a windows app does? For example, if I want to handle when someone just presses a key (keydown) on a textbox in a webpage?
The functionality that we want to create breaks down like this:
We want to create a "smart" search box at the top of our page. When the user starts typing, a little panel or some element should become visible and it will have some check boxes on it. They can search for one or many different types of searches: First Name, Last Name, Business Name, ZIP, Customer Number, and Contact Info. As they begin typing their search, we need it to execute some code that attempts to figure out exactly what they are searching. So if it can tell they are typing in alphabetic characters and not numbers, then we know to NOT check the Customer Number box, but we will want to check the First Name, Last Name, and Business Name boxes. If they start typing a number, we know that we can check the Customer Number box and leave the First Name and Last Name, etc boxes unchecked. If they type a number that is 5 digits, then we know to check the ZIP and Customer Numbers both. Any other length number characters and the ZIP will be unchecked. And any other rules like these that we might want to implement in the future. The idea here is we will almost always be able to tell what someone is searching, but the user can always check any box that they want to search for if they so choose. For example, if a business is named "123 Plumbing Company" and they just want to search the Business Name field for a number, they can over ride it and do that. Otherwise, they just can blindly type their search and hit enter and the program will usually know what kind of search they are trying to do.
I come from a strong windows app development background and have just recently tried to do some web development professionally. A quick few sentences on what philosophy I am missing out on as far as a more robust and "Windows App-like" webpage would be appreciated if anyone wants to coach me on that area and point me in the right direction!
Also, in my example we are using master pages. So if you can imagine a typical master page that has a logo top left and a search box and button top right, then you can picture what we have. Its simple looking. But with the content page being a separate aspx page, we are having trouble referencing it after a search is performed anyway. So what I mean by all this is The masterpage.master has a search textbox. They type something, hit enter. We then want a gridview that is on our default.aspx page to update with the results of the event that was fired from the masterpage.master.
My windows app background tells me to just point to it like I would from two different forms. Like if I had a form1 with a search box on it and I wanted it to show up the results on form2, I would just say Form2.Show: Form2.GridView = whatever.
Of course, with my confusion of what the scope of these asp.net pages is, I am having a difficult time just visualizing everything and how they are inter-related.
So I guess to recap here:
1) How do I tap into more events with textboxes or any other asp.net control. Is the answer AJAX? If so, can you elaborate just a little bit?
2) How would I use the keypress or keydown type of event to make a panel or some kind of content holder to become visible when the textbox gets focus from the cursor and go back to being invisible if it loses focus.
3) What about the scope in which asp.net pages behave?
I use DropDownExtenders everywhere in my project, but it bothers me that it's not visible all the time. It looks like an usual TextBox :-(

Using javascript or jquery, how can I make a Required Field Validator control (of ASP.NET) visible. If we check the viewsource of the Required Field valiator, we can see that the visibility is false initially. $("#spanReqFieldValidator").show() / fadeIn() wont work.
From googling, I understand that jQuery has some issues with visibility attribute.
