AJAX :: Setting Value Of Textbox Inside Panel Which Is Set To Visible False
Mar 9, 2010
I have an update panel which has 2 set of controls each in their own separate panels. We can select either panel by a checkbox list and they become visible. Now I am trying to set a value by javascript in the panel that becomes visible on my checkbox click but the problem is that I cant access the controls through javascript as they are not rendered on page as visibility is false.
I cant find the controls inside the page source even though they are visible on page so javascript cannot access them. Is there any way other than doing a postback and setting them visible to access them via javascript?
On the other hand i have a MultiView that contains Several view that in turn itself contains several controls .
In multiview we have to set ActiveViewIndex for the view which we want to see.
That same thing can be done through Panel containing another seleral panel's and setting its Visible property to True/False accordingly.
Is seems Multiview is just using this Visible property internally to render controls .Since other views (whose Index is not set to be active Index) are processed on the server for its Whole life cycle(I am confused here..whether i am right or not) .Same thing perhaps happen when we use a Panel insteed and use Visible=True/False. So, what is the difference between MultiView and Panel taking this scenario ?
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.

I know it has something to do with how my findcontrol code is written, but I can't figure it out.
In the problem code, there is a modal popup that is shown using .Show, and that part works fine. A textbox in the popup needs to display text, but I can't get that part to work.

I have a Gridview with some template columns. Inside one of the columns, I have a ImageButton with a serverSide OnClick handler to show or hide a panel. And all the panels by default are hidden. What happens is that when I click the imageButton the first time the panel gets displayed, but if I click the same button, on the same row again, - where the panel is now visible - the panel doesn't hide itself. Here's what happens when the imageButton is clicked:
In the main code, I just have a panel inside a DataList control. I'm attempting to adjust change the visibility to true or false in the code behind, but it's not having any affect on the panel.

I have added a Ajax tab control into my page and first tab includes the data entry part to a table and second tab is update the data in a table (Database).
The problem is in first time when I click submit button without filling any details it shows the error messages (I set required fied validators) but next time it didn't show the error message but it not submit the page. So I understood that the validation controls are worked but it doesn't show the error message. Is there any solution?
When popping up a client side message box, the panel that is tied to my AJAX ModalPopupExtender via PopupControlID, shows on the screen until the message is cleared.
I am having trouble wiht my AJAX collapsible Panel Extender. I have the CPE opening a panel that contains the Table of Contents of a document being displayed on the page. A user clicks on the link for a certain part of the document, the event triggers a C# function that gets the file that particular section is contained in an displays the section. Right now you have to, of course, click on the TitlePanel to open and to close the CPE. What I want to do is have it close automatically whenever a link inside the content panel has been clicked. I have tried placing this.cpeTOC.Collapsed=true; in the functiion that gets the files but it does not work. I have also tried the autocollapse property of the CPE and it just collapses whenever someone moves thier mouse from the titlepanel.
I have 2 updatepanel UpdatePanel1 and UpdatePanel2. Intialy updatepanel2 is invisible. In updatepanel1 there is a dropdown list, whose Selected Index Method change makes UpdatePanel2 visible.The code
UpdatePanel2.visible =true;
seems to run without any error, but updatepanel2 is not visible on the page. Is there anyway to make it work.
I have a GridView control inside one Update Panel and a detail section inside another Update Panel. Initially, the detail section is hidden and when a GridView row is selected, the Detail panel becomes visible. Everything works fine except that if the GridView contains more rows and covers most of the user's screen, screen doesn't shits to the start of Detail section.I can use anchor but was just wondering if there is any other way of achieving this. Also the Detail section has multiple nested Update Panels and if I use anchor, then any of the child Update Panel's update will move the screen to the beginning of the detail Section.
I 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:
[Code]....
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?
I have put a TabContainer inside an UpdatePanel. The TabContainer's TabPanels get populated with the content dynamically. Whenever the browser is refreshed (F5), the TabContainer does not display I get a javascript error
Message: 'undefined' is null or not an object
This only happens in Internet Explorer. If I put the cursor in the address bar and press the 'Enter' key, the TabContainer shows up again and the javascript error goes away.
