AJAX :: Divs's Inside UpdatePanel Become Grey On Update In Firefox
Apr 1, 2010
The first one shows the page with a form which has an updatepanel around it. The second one shows what the page looks like for half a second when clicking the submit button in firefox.
Every <div> tag inside the updatepanel go grey (the background color of <body>) creating weird flickering... How can this be avoided? It seems the div's go transparent but they don't show the white background color of the div surrounding the form, it show the body background color.
I need the updatepanel around the form for some of the validation controls to be displayed so not letting it span the whole form is not an option.

I have a button that is inside of an updatepanel, I want it so that whenever the user clicks on the button it would update items in the updatepanel and after that it would activate the animationextender but I can't do that as of now because on the button I have OnClientClick="return false;".

I have a script inside an updatepanel. This script needs to be inside the updatepanel as it must be located in that spot.
Now when we click the "LinkButton" to update the updatepanel, the script will dissapear.
It seems that the script only is initiazed on the first Page_Load and Refresh of the page.
How can we keep it when pressing the "LinkButton"?
Complete code is below:

i have a website with three UpdatePanel Control and inside of each UpdatePanels has ONE Gridview and a SqlDataSource Control.
all gridviews are connected to its own SqlDataSource Control. so technically when i run my website all gridviews automatically get their data from their respective SqlDataSource Control and display them accordingly.
but what i need to do is instead of letting all the update panels to load each gridview their data upon Onload event, i need the updatepanel to update on queue, (Technically changing the UpdateMode to Conditional does not solve my problem.) there will be an event which will trigger the updatepanel to update later.

i am using a TabContainer and at each TabPanel i have embed an UpdatePanel in order to update each tab alone.
this is my code:
[Code]....
the problem is that it makes several seconds to update each tab (the same time for every tab) and i asume that this is happening because it updates all the TabContainer and not the selected Tab.

I have a gridview inside UpdatePanel.
Inside gridview there is a dropdownlist and a button on each row. On button click I am opening a panel through Modal popup extneder.
Inside that pop up there is again a dropdownlist. I am adding an item into this dropdownlist based on the selection from the dropdown inside gridview.
like ddl.items.insert(0,'xyz');
But first time this inserted item is not getting reflected in the dropdownlist. But after one postback this item is getting reflected.

I'm trying to add and edit an image which is located in a detailsview which is inside an UpdatePanel. After I read relevant topics in the forum I installed the Ajax Control Toolkit. Below is my source code. When I used it only for insert new image it worked great. The problem caused when I tried to implement it on the Edit mode, i.e. when I tried to edit the image and upload a different image. Unfortunately it didn't work as I hoped. Nothing happend and the image hasn't been changed. I also tried to change the IDs (AsyncFileUpload ID) to be the same in both places but it didn't work either.
The source code:
<asp:DetailsView ID="dvMovie" runat="server" Height="50px" Width="695px"
AutoGenerateRows="False" DataSourceID="sdsMovieById"
BorderColor="#E7E7FF" BorderStyle="None" BorderWidth="1px" [code].....

I was just after some help to put the following code into a loop. I have 6 div's with id's ImgDetails1 - ImgDetails6 and 6 buttons
with id's 1 - 6
if 1 is pushed it should hide the other divs but ensure div1 is shown. the same applies for every other
div.
I can do this the long way writing logic for each div but I am not the best with js and have failed
at each attempt to put the code in a 1 - 6 loop to hide all divs except the one selected and make sure that is shown.

I have two updatepanels on my site (upanProfileSearch and upanMemberList). When I hit the button in the upanProfileSearch it should bind the Data Items in the gridview in upanMemberList and here make a RowFilter on the text in upanProfileSearch. When I make a run to curser, I can see, it happens. It makes a RowFilter. but it doesn't update the gridview. Can anyone tell me why it doesn't update? I have UpdateMode="Always" and RenderMode="inline" on both UpdatePanels.

I've exempted the irrelevant bits of code. Essentially, I am trying to change the URL of an image control inside of an update panel inside of a custom user control from a function called inside an update panel from my main page. Using UpdatePanel.Update() isn't working: I end up waiting for the next full page POST to occur before all the updates I make to CustomControl from buttons within the main page's update panel are visible. I verified that Update() was being called via the debugger: there are no issues in that department.
Here, you can see Custom Control and the Button declared. The button is in an update panel to avoid giving a full POST and causing the whole page to reload.
<cust:CustomControl runat="server" ID="CustomControl1">
<asp:UpdatePanel runat="server" ID="UpdatePanel1"> <ContentTemplate>
<asp:Button id="Button1" runat="server" OnClick="DoStuff" />
</ContentTemplate> </asp:UpdatePanel>
This control stores images within their own seperate update panels because rerendering the images is very slow (it requires processing arrays of millions of datapoints) and the user only ever needs to modify one image at a time. I'm using Image1 as an example.

I am having this update panel page refresh problem with Firefox 3.6, not sure if anybody else has seen it.
It happens to me on pages with multiple ASP update panels. For example, I have two dropdownlists nested inside one of the update panels, and those dropdownlists do allow AutoPostback. For whatever reasons, it triggers other update panels to refresh even though it shouldn't. It only happened in Firefox 3.6, I haven't seen it in Firefox 3.5.x or Chrome or even IE 8.

I have found an odd bug in my application. I have a dropdown status which is bound to my gridview. On selecting a status from the dropdown the selectedindex then fires and binds the results to the gridview.Now the strange behaviour in firefox and not IE:If I have a dropdown open and an ajax update fires on my gridview the option is selected from the dropdown (just by hovering my mouse over it rather than selecting it) and the results bound to the gridview. This does not happen in ie as you should have to physically select an item from the dropdown rather than firefox selecting it for you because you happened to hover over an option when the update event fires.

I have a GridView that is inside a Web User Control, that is inside an ASPX Page, that is wrapped by the Master Page.
Inside a GridView, I have a template field with DateTime type that has a TextBox inside EditTemplate. I extended this TextBox with CalendarExtender and it works ok in Internet Explorer.
I also have a DetailsView control on the same WebControl that I use to Insert new enrty. InsertTemplate for this field is the same as in GridView (Textbox with Calendar extender).
The problem occures when i click on the Edit link (or try click on the link that displays DetailsView in Insert mode for adding new entry) in any other browser: Chrome, Firefox, Opera.
The problem itself is that the calendar extender does not get poped out. I have a UpdateProgress Control on an ASPX page, that thie control is loaded into, that shows loading image while page is being posted back asynchronously.
In internet explorer the loading image is shown for jst a moment and then dissapears. Calendar extenders works perfectly.
As for the other browsers, the loader does not dissapear and none of ths postback links are working, as if it was waiting for the previous postback event or something else to finish. Finally I have to reload the page to get to the inicial stage or click a direct URL link to get somewhere else.

I am new to this forums.I am using the Google Chart API to show the chart on the page on the drop down selection. This is working fine in IE but not in firefox 3.6 with update panel. When I remove the update panel then this is working fine in all browsers but if I use update panel on the page then chart is disappering after changing the selection of drop down. It seems that google chart is not compatible with update panel.
My code is something like this. Please suggest where I am doing wrong.

I have a menu of buttons inside an UpdatePanel (UPD_Menu) so that buttons can be enabled/disabled without refreshing the entire page. When a user signs in, the Sign Up button is disabled and the Profile button is enabled. Likewise, when the user signs out, the Sign Up button is enabled and the Profile button is disabled.
Inside this UpdatePanel (UPD_Menu), along with the buttons, is a ModalPopupExtender that is fired by the Sign Up button (TargetControlId="BTN_MenuSignUp") that pops up a dialog Panel (PNL_SignupProfile) that contains yet another UpdatePanel (UPD_SignupProfile) that contains a Submit button as well as a Cancel button (CancelControlId="BTN_SelectCancel").
The behavior I am getting is when the user clicks no other button than the Sign Up button, the dialog (PNL_SignupProfile) pops up and is modal. The Submit button closes the dialog and makes the once-hidden panel appear under the menu of buttons. This is not good as only the inner UpdatePanel (UPD_SignupProfile) should be updated without affecting the outer UpdatePanel (UPD_Menu). The Cancel button works as it should by simply closing/hiding the dialog.
If a user clicks any other button in the menu first, nothing happens ( no codebehind yet) but when the dialog (PNL_SignupProfile) is shown, the Cancel button causes the hidden Panel (PNL_SignupProfile) to appear under the buttons. I've tried many different things to no avail...including putting the dialog panel in different places and even controlling the ModalPopupExtender from code.
The only code I have so far is for handling the signin/signout and enabling/disabling the signup and profile buttons based on user signin. There is no code yet to handle the menu of buttons nor the submit button of the popup dialog.
Here is the code:
