Ajax update panel refresh and dropdown behaviour in firefox


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.

Anybody had the same problem or does anyone have a fix out there?

Your help would be appreciated.





re load javascripts and jquaries after ajax refresh


I use javascript hints for my textbox and when page loads I set that, but after submiting data for example in the case of error in input and need for inputing again the data it doesn't show the hints, which means that when ajax sends Httprequest and gets Httpresponse and refreshes the update panel , that panel doesn't accept loaded jscripts again, so they should be loaded again.

I do not know how to do that in asp.net, any tips or recomendations?

Ajax Asyncfileupload doesn't work as soon as I put it in a control


Hi guys,

I can't get my <ajax:asyncfileupload> working and I don't see why...

When outside any panel or table it is working well, but as soon as I put it in a <asp:panel> or table I get a strange error which seems to be on client-side but I don't understand what's happen here. Here is the code and code-behind and Javascript.

Here's the error: 


Here's my front-code:

<%@ Page Language="VB" MasterPageFile="~/masterpages/mpSqueletton.master" AutoEventWireup="false" CodeFile="frmAdmGestSocietes.aspx.vb" Inherits="adm_frmAdmGestSocietes" title="Untitled Page" %>
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajax" %>

<asp:Content ID="Content1" ContentPlaceHolderID="cphHead" Runat="Server">
<script type="text/javascript" language="javascript">    
        function uploadError(sender,args)
          document.getElementById("<%= lblStatus.ClientID %>").innerText = args.get_fileName(), "<span style='color:red;'>" + args.get_errorMes

Window.Open in AJAX Accordian Panel Opens Link in Same Window

I'm using the following span to open a page in a new window. What is INCREDIBLY odd is that it is exactly the same code from three different pages, but the first refuses to open in a new window. The only difference is that the first example resides within an Ajax Accordian Panel so I suspect that it might be an Ajax related issue. Ideas? Does not open in new window.<span onclick="window.open ('http://[domainname]/Mercury/production/content/directory/DirectorySideBar.aspx','mywindow','width=271,height=498,scrollbars=no');">   Opens in new window<span onclick="window.open ('http://[domainname]/Mercury/production/content/directory/DirectorySideBar.aspx','mywindow','width=271,height=498,scrollbars=no');">   Opens in new window<span onclick="window.open ('http://[domainname]/Mercury/production/content/directory/DirectorySideBar.aspx','mywindow','width=271,height=498,scrollbars=no');">  

AJAX update panel and update progress controls

I have writtena Crystal reports web application, that prompts ths user for parameters and then apply them and exports the report to a folder as .rpt and then display the report. I prompt the parameters on one screen and then display the report on another page. I have the AJAX update panel and update progress controls in the parameter page. When the user enters the parameters and click on ok, I export the report and then loads the report to a session report document and transfer the user to the second page where the report is displayed. I use the following code to do transfer to the seconds page. I have excluded the report load and parameter assign code here.rpt.ExportToDisk(ExportFormatType.CrystalReport, "c:\reports\testrep.rpt") Session("rpt") = New ReportDocument Session("rpt").load("c:\reports\testrep.rpt") Response.Redirect("show.aspx") In the second page I have the following: rptViewer.reportsource = Session("rpt") My problem is this works one time and then stops working the second. What I found out was it comes to the statement: Response.Redirect("show.aspx") But it does not even load the show.aspx page. It stays on the parameter page. There are no errors displayed. I could not see any errors when I debug the application also. And out of the blue it works

How to refresh only single update panel

page inside update panel doesn't refresh the session object after postback of any control



I have many controls like dropdown, radiobuttonlist, etc on my page and I put all these controls inside the update panel so that the page doesn't look to be posting back when something is selected. Now the working on the page is very smooth. But the session object isn't getting refreshed even if I postback to the server and as a result even if the users are working on the page they are being sent to the login screen after 20 mins.

Is there anyway where I could put all the controls in update panel and still refresh the session after any postback(dropdown selection)

Any help is greatly appreciated.

Thanks in advance

How to Refresh Gridview data from update panel in specified time

update panel woes... question for superstar AJAX gurus



This has got me completely confused... not sure if I've been at it too long and am missing something, or if this is a bug?

I have a webform with an AJAX update panel. In the panel there are 2 controls. One is a textbox, the other a listview.

I'm using the ClientScriptManager to take advantage of the "OnKeyUp" event to cause an autopostback.

When text is entered into the textbox, it runs the textchanged event, which puts data in the listview.

So far so good. All works fine with one exception.

Problem is that with IE8 the textbox loses focus on the SECOND text entry, even though it's specified in my code to focus on textbox after the textchanged event fires. And with Firefox, it doesn't cause the textchanged event to fire at all.

I don't get it??

Here's my code...

    Sub Page_load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load


        TextBox1.Attributes.Add("onKeyUp", Page.ClientScript.GetPostBackEventReference(TextBox1, ""))

    End Sub

    Sub TextBox1_TextChanged(ByVal sender As Object, ByVal e As EventArgs) Handles TextBox1.TextChanged

        Listbox1.Items.Add(New ListItem("ListboxItem", "ListboxValue"))

        TextBox1.Text = ""


How to track Collapse/ Expand event of AJAX Collapsible Panel Extender to call javascript ?



I am working with AJAX Panel Collapsable panel extender.

The Panel which is to be collapsed/Expanded using AJAX panel Extender contains one custom control, containing 3 Radio buttons one of them is set checked through a javascript function when page loads. I have kept the default property of AJAX collapsable panel as Collapsable.

   CollapsedSize="0" Collapsed="True" CollapsedImage="~/public/img/arrowRightWhite.gif"
   ExpandControlID="pnlCollapsable" ExpandDirection="Vertical" ExpandedImage="~/public/img/arrowDownWhite.gif"
   ImageControlID="Image1" SuppressPostBack="true" TargetControlID="pnlSearchCriteria">

But problem is that when page loads, collapsible panel gets collapsed but it resets the radio buttons in custom control. i.e. First radio button does not get checked. Script for Collpsable panel is as follow. I want to call some javascript code when the panel is Collapsed or Expanded. Is there any way to track Coll

refresh update panel content with new css styles


Ok, I was working on this last week and took a break from it to 'regroup' and start over.


Here is what I'm trying to accomplish.

1. have  a web form with dropdowns to allow the user to select font sizes, colors, background image, etc.

2. I want to the form to be updated with the new styles in an update panel.

3. Once the user clicks the apply button, I want the updatepanel to refresh with the new styles.


I tried this by creating an css on the fly, but the updatepanel wasn't picking up the new css without doing a full page refresh, (which we don't want to do).

I only want the updatepanel refresh and either use inline styles, a <style> on the web form etc,

any suggestions or recommendations on how to accomplish something like this?
