Web Forms :: Panel Set To Visible Is Suddenly Not Working When It Did Before And No Code Changes?
Jan 20, 2011
We have an asp.panel that by default is set to visible=false. When a checkbox is clicked the panel is set to visible=true. The checkbox is set to autopostback and viewstate=true as well as the panel's viewstate =true. This code has worked perfectly for several years and suddenly it has started throwing an error on the built in .net java function below. It doesn't do it in the IDE when you run it either. The bold line is where the exception is being thrown.
function
ValidatorCommonOnSubmit() {
var result = !Page_BlockSubmit;
Page_BlockSubmit = false;
event.returnValue = result;
return result;
}

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 have a severe problem. This code was working not 3 hours ago and has been for days, and suddenly it stopped.
Here's the web page code:

And here's the Back end Code:

We have clients that can't access the website and it's causing major issues so I need a response as soon as possible with any suggestions or ideas.I'm using a recursive search and the error I'm getting is:
Unable to cast object of type 'System.Web.UI.Control' to type 'System.Web.UI.WebControls.Label'.

AJAX :: pageLoad suddenly stopped working?

This is not a big issue since it's quite easy to bypass by making a new project and copying everything on it, but it bothers me quite a bit that I can't figure out what it is about. In short my calendar and calendar extenders stop working suddenly. The last time this happened I made some changes to the pages code behind, then hit undo gazillion times to go back to the last save. After that I hit debug and lo and behold: calendar did not respond to any clicks and any text field with calendar extender did not show calendar on clicking them.
This happens in both IE8 and FireFox 3.6 and no amount or restart, rebuild and other such tricks do nothing. The only thing that I can figure out to solve the problem is either use a backup copy of a version that works or make a new project and then copy all the files from the not working into the new/earlier version and all works again. I was able to track down that this seems to relate somehow to AJAX as when I ran the debug I mention above, I got error messages on the web page saying something about AJAX. This however happened only once and I cant get it to happen again (and thus can not remember much about what it said).
Also when I debugged the event handling the calendar click, I get an error message like this: There is no source code available for the current location Then it opens a file search window trying to find some cs file inside the ajax control toolkit. However this only happened the first time I tried debugging the event and I can't remember more details about it. Now I just get that error message when debug exits the event.
So end analysis on my part: The ajax control tool kit gets knotted up all of a sudden for some mysterious reason and is tied to that particular project. Can anyone tell me what this could be about?

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:
protected
void ImageButton1_Click(object sender,
ImageClickEventArgs e)
{
ImageButton imgBt = (ImageButton)sender;
Panel compRecDetails = (Panel)imgBt.NamingContainer.FindControl("CompanyRecDetailsPanel");
if (compRecDetails.Visible ==
false)
compRecDetails = true;
else
if (compRecDetails.Visible ==
true)...............................

I have a panel that contains several controls.
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 two panels on a page. Panel A, and then within Panel A is Panel B. If Panel A's visibility is False, shouldn't Panel B's visibility automatically be false because it's within Panel A?

I have a Panel that I'm setting visible=true explicitly. The debugger passes over that line and visible still evaluates to False on the next line. Obviously as a result, the Panel is not shown. How is this possible?

<asp:Panel ID="pnlValidate" runat="server">

I was using the code below to query the database and to show or hide content if the result was true of false. I use two panels so I can dispaly the right content block depending on EVAL
<asp:Panel
ID="Panel1"
runat="server"
Visible='<%#
(Convert.ToBoolean(Eval("GenreId"))).Equals(false) %>'>
<asp:Panel
ID="Panel2"
runat="server"
Visible='<%#
(Convert.ToBoolean(Eval("GenreId"))).Equals(true) %>'>
This was working with a CSS layout but I had to place all the content in a table and now it does not work. Is there another way to do it

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?

I'm new to the world of Update Panels and i'm having a hard time figuring out how to use them properly.
I have a form that has a table(TABLE1)...and inside TABLE1 i am linking to a sql data source....at the bottom of the table i have a 'Add' button.
When the user clicks the add button...a modal popup appears (POPUP1) and inside the POPUP1 the user can click a link that can add a user...when the link button is clicked...a panel within POPUP1 is set to visible = true.
I have one update panel around the whole table and the add button...when i click add and then click the link to add a user....the modal popup disappears.
