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?
View 1 RepliesI 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 an update panel and inside it has a panel with a contact form. Above update panel is an update progress bar, with an ajax loading icon.
What I wanna do is, when contact form is submitted, the panel is hidden, and the loading icon is shown.
I did it by having this in btn_onclick:
System.Threading.Thread.Sleep //not sure if correct spelling but anyway
pnl.Visible = false;
Somehow, the icon shows out but the panel still visible down there. Is there something I am missing?
The javascript generated by the asp.net SciptManager control seems to have a bug and cant handle hidden UpdatePanels. A javascript error is thrown when a control within one updated panel tries to make another update panel visible. Is this a bug with ASP.Net ajax? And does anyone have any ideas how to get around this? heres is an example of what im trying to do
<script type="text/C#" runat="server">
protected void LinkButton1_Click(object sender, EventArgs e)
{
Panel1.Visible = true;
}
</script>
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:LinkButton ID="LinkButton1" runat="server" OnClick="LinkButton1_Click" Text="Show Panel"></asp:LinkButton>
</ContentTemplate>
</asp:UpdatePanel>
<asp:Panel ID="Panel1" runat="server" Visible="false">
<asp:UpdatePanel ID="UpdatePanel2" runat="server">
<ContentTemplate>
</ContentTemplate>
</asp:UpdatePanel>
</asp:Panel>
this is the javascript error that gets thrown when clicking on the "LinkButton1" link. This error comes from the javascript that is generated by the asp.net ScriptManager control
Error: Sys.InvalidOperationException: Could not find UpdatePanel with ID 'ctl00_ContentPlaceHolder1_UpdatePanel2'

i have a panel(visible false) in a page and a user control. i have a button in a user control when i click that user control button then i need to make the panel visible in the page... (panel which is not in the user control)...
View 3 RepliesI 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?
pnlValidate.Visible = true;
if (IsPostBack) return;
<asp:Panel ID="pnlValidate" runat="server">

I have a Panel with property, Visible set to False
<asp:Panel ID="pnlUpload" runat="server" Visible="False" />
and i try to make it visible using javascript as code below
document.getElementById('<%= Panel1.ClientID %>').style.visibility = 'visible';
I have the AsyncFileUpload control within a <asp:Panel> control that I toggle visibility True/False.
For Example when the page loads pnlEdit.visible = False. Then when a user clicks on a detail record in a grid I display the panel with the AsyncFileControl ie: pnlEdit.Visible = True.
Because the the AsyncFileUpload Control is not displayed on the page right away it errors when you try to upload a file. Would anyone know how I could preload the control or configure it.

and below is the code where I am trying to update one of the hidden field with my CS code. Interesting, when I am trying to debug its showing all the values, however when I see it f on page source it doesn't give any value. Here is my aspx.cs code:
protected void Timer1_Tick(object sender, EventArgs e)
{
DataTable dtTrips = null;
WEX.Prototype.Data.TripDA tripDA = new WEX.Prototype.Data.TripDA();
string tID = hidTripIds.Value;
string[] tripIDs = new string[1000];
tripIDs = tID.Split(',');
foreach (string tripID in tripIDs)
{
TripSummaryBO tripSummaryBO = tripDA.getTripSummary(Convert.ToInt32(tripID));
if (tripSummaryBO.tripLastEditedOnDate > Convert.ToDateTime(hidCurrentDate.Value))
{
WEX.Prototype.Service.WSProxies WSProxies = new WEX.Prototype.Service.WSProxies();
dtTrips = WSProxies.Build();
Session["AllTrips"] = dtTrips;
dtTrips = (DataTable)Session["AllTrips"];
if (dtTrips != null)
{
if (cnt==0)
{
hidTripDetails.Value = ("Trip name-" + tripSummaryBO.tripName + " was modified by user " + tripSummaryBO.tripLastEditedBy);
}
else
{
hidTripDetails.Value = hidTripDetails.Value + " <br/> " + ("Trip name-" + tripSummaryBO.tripName + " was modified by user " + tripSummaryBO.tripLastEditedBy);
}
BuildGridViewControl(dtTrips);
cnt = cnt + 1;
}
}
else
{
//upTripsGrid.Triggers.Clear();
PageInit();
}
}
}
I have a tab container with two tabs. In one of the tab panels, I have a button. I want by pressing the button to make a label in master page visible:

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.
I making web application for iphone user. I have HTML table structure inside asp.net panel and i have set panel's scrollbar property to vertical. It works fine in all the browsers but not working in iphone browser.
View 1 RepliesAre there some existing examples of making a DIV or panel visible or not visible based on an ajax event?
View 2 Replies what do you mean by below things..
divProgramm.visible=true | false| true;
i dont know how this thing is evalulted in asp.net c#.net.
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 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 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.
View 6 RepliesI have a user control which has a gridview with hidden fields in some of the template columns. The grid columns are created and bound by code dynamically in each postback and not in design mode. The gridview is placed in an update panel. In my aspx page where i use the user control , there is a dropdown which fires postback and based on the selected value of the dropdown the grid data gets filtered. The dropdown in aspx is not part of any update panel.
After the postback of dropdown, the grid data gets filtered and the grid is rebound with fresh values. The values in the controls like label, button or link button are bound correctly. But the values in the hidden fields are not refreshed and always points to the values of the rows that was generated before the postback of the page (initial page load).
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 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 text box and some validation on it. I want to make a panel visible only when
it is successfully validated,i.e.,textbox entry is valid.Also,I want to capture the entered valid value(it should be integer within 1-8) in a session,based on this number,I am going to add that many rows in an editable grid view.
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.
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?
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:

void ImageButton1_Click(object sender,
ImageClickEventArgs e)

ImageButton imgBt = (ImageButton)sender;
Panel compRecDetails = (Panel)imgBt.NamingContainer.FindControl("CompanyRecDetailsPanel");
if (compRecDetails.Visible ==
false)
compRecDetails = true;

if (compRecDetails.Visible ==
true)...............................
