ScriptManager And EnablePartialRendering - Panel With The Loading Stuff Doesn't Display

Feb 24, 2011

I have a page that uses ajax scripmanager > progressupdate so I can display the user a message of "Loading, wait..". Now, my question is the following. I have the EnablePartialRendering set to true, mainly because if I set it to false my panel with the loading stuff doesn't display. When is set to true, then if I want to set the text and visibility on a row that is normally set to visible=false, it just doesn't happen. My row doesn't show. My "Loading" message will only display if a stored procedure exist, if it doesn't I just need to let the user know.

AJAX :: ScriptManager.EnablePartialRendering - Demonstrate Partial Rendering Without Full Page Reload

Feb 27, 2010

I am reading a tutorial article on this site about Partial Rendering using ScriptManager.EnablePartialRendering - [URL] The article uses button_click to demonstrate Partial Rendering without full page reload. I copy exactly the same codes but everytime I click the button the page refreshes.

I have examined after the page is loaded - ScriptManager1.EnablePartialRendering = true ScriptManager1.SupportsPartialRendering = true I am using vs2005 .NET 2.0 and AJAX extension 1.0 (same version as used in the article)

AJAX :: Update Panel And The EnablePartialRendering Set To True On The Page / Page Size

Feb 16, 2010

I have a form, with an update panel and the EnablePartialRendering set to true on the page. Here's my problem, the page size with every AsyncPostBack gets larger, even if my code makes no changes to the markup. It also, never stops... it just keeps growing about 3-4K with every AsyncPostBack. If EnablePartialRendering is set to false, full postbacks do not cause the page size to grow like that. It's like it's sending resources and then never getting rid of them out of the page even though they're not being used because an updated copy has come down.

1.) Is it supposed to work like that?

2.) If it's not, what can I do to not have 4K added to the page size everytime an AsyncPostBack occurs (not again, full PostBacks do not have that same behavior).

3.) This behavior happens whether I compress the ViewState or not (I am using ViewState compression). However, the ViewState size is NOT growing... it's the size of the content in the page that is (I'm monitoring the ViewState size/the Page Size closely).

AJAX :: ScriptManager Not Loading Script Resources When Page Accessed By Chrome?

Dec 4, 2010

During development of my site, I have optimized for all the common browsers, including Chrome and it works fine when tested locally on my dev machine. However, I have found out that when put on my live dedicated server, the pages that are delivered to Chrome do not contain the AJAX scripts and for example the treeview, which should load its branches dynamically, renders in such a way that a full postback occures. This completely breaks the site in Chrome.

Considering all things I could deduce about the problem, I would suppose that I may need a newer version of MS AJAX that supports Chrome, but I cannot find any version older than Feb 2007 and anyway, Microsoft .NET Framework 3.5 SP1 is installed on the live server. That should contain the propper MS AJAX anyway, shuldn't it?

I've been researching this for more than a whole day now and cannot figure out what's wrong. I even matched and compared all settings of the site on IIS 7 on both my dev machine and the live server. Except a couple of, as far as I can say, unrelated additional entries on the live server, those are identical as well.

I tested using Fiddler that all the difference is made by the User-Agent request header. If I just add


behind the "Mozilla/5.0" bit, all is fine and I get response containing all it should. I suppose I could create a HTTP module that would add that bit to the mentioned header and then add that handler to the pipeline, but that would be an ugly solution, curing the effect, not the cause of the problem. And it may cause other problems in Chrome, too.

So my question is: What do I have to do (set up, instal) on the server so that the MS AJAX framework actually realizes that it can also handle Chrome?

I'm going to include few snippets of code to demonstrate the differences between the same page loaded in the same Chrome, but from two different sources - my dev machine's IIS (A) and from the live server (B). The applications running on both of these web servers are identical.

And the following shows the difference in generated HTML at the top of the <body> element:





There is still the typeof(Sys) === 'undefined' bit of code, which tells me that ScriptManager is still being loaded, but decides that other AJAX script should not be. But it does not even initialize itself so Sys is in fact undefined after the page is loaded.

There are also differences at the end of body:



versus B:

Loading ScriptManager Only Once Either From Master Page Or Content Page?

Sep 6, 2010

I have an web application of 200 web pages and all has a single master page. Most of the content pages use AJAX controls so most of content pages has its own ScriptManager. Now I have a requirement to add a link with HoverMenuExtender control and for that I need to put ScriptManager in the Master page, but it is working only in the content pages where there is not ScriptManager.

All the other content pages which has ScriptManager throws the error Only one instance of a ScriptManager can be added to the page. I don't want to work on most of the content pages again to remove ScriptManager. Is there any easy way to do this something like coding in Master page which decides if there is already ScriptManager already, then don't load it.

AJAX :: UserControl With ScriptManager And UpdatePanel, Some Pages With ScriptManager?

Feb 8, 2011

I have a user control with both an UpdatePanel and a ScriptManager.

Some pages in the system have a ScriptManager of their own, and need to include the UserControl.

This throws the "You can only have 1 ScriptManager" exception.

If I remove UserControl's ScriptManager, I'll get 'UpdatePanel1 requires a Script Manager" exception.

I've tried to modify the UserControl to dynamically include it's own script manager if none exists. But all the methods I've used before involve adding a delegate to Page.OnInit-- which won't work, since the UserControl Init fires first.

Because the system designers here like making my life difficult, I can't create a MasterPage, or a BasePage for the system in inherit off of. I'd be stuck going to each page an adding a ScriptManager before the UserControl on each of them. Is there any way of, in the UserControl, detecting if the page has a ScriptManager, and if not, adding it dynamically in a way that makes the UpdatePanel happy?

AJAX :: EnablePartialRendering Causes JSON Not To Be Written To The Browser

Jan 29, 2010

Am using UpdatePanel on a .aspx page with a User Control. This user control is AJAX enabled and is using UpdatePanel and ScriptManager on the aspx side. When I have EnablePartialRendering set to true i.e. <asp:ScriptManager runat="server" id="someId" EnablePartialRendering="true" >

and use ScriptManager.RegisterClientScript to write JSON from server side (C# code) - it is not written to the browser i.e. it shows empty square brackets when I view source in Browser i.e. var SomeVar = [] As soon as I change EnablePartialRendering ="false" and refresh the page JSON starting showing up in the browser i.e. var SomeVar = [{"id","1"}{"id",2}]

I have a website using Telerik controls for ASP.NET. When an AJAX request starts, the Loading Panel (defined in the master page) will display, with a loading image, text, and faded white background color. It works totally fine in Firefox and Chrome, but the background image and text don't display in IE8. All that displays is the white background.LoadingPanel code: Loading ideas why IE8 isn't displaying the images? I've inspected the page source, and they're there in the CSS.

AJAX :: Update Panel - Changed Image Not Loading?

Oct 28, 2010

I've got a working update panel which works fine when updating a label control, but I can't get it to work with an updated image (initial image loads fine - the problem is with the update). I think the problem maybe that the image name and location don't change, only the physical file. In other words, I've loaded the page, then updated the image (same name and location), but the image does not update with the label? Here's my code:

AJAX :: Update Panel Doesn't Seem To Be Triggered?

Mar 14, 2011

I have a simple table with 5 text boxes, above that i have a dropdown where you make a selection, if there are any records of associated with the selection, then i display in the fields..

A while back this was working, you could make a selection and the fields were within a update panel and they were populated. But im revisiting the pages to make some updates and changes and noticing that the page no longer populates the fields when a selection is made..

Is there anyway to debug the updatepanel? I put a breakpoint in my selectedindexchanged event and my Db call is returning values and the textboxes .TEXT values are being assigned the right values in the code behind, but the fields never show up..

This page hasnt been touched since it was wworking last, so need to see how i can test / debug the update panel to determine what coudl be causing it..

Hidden Field In Update Panel Doesn't Get Updated

Feb 8, 2010

I am using C# for my programming. I am facing issue, that my hidden variable value is not being updated when it is in update panel. Please see below code for aspx:

<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<asp:Timer ID="Timer1" runat="server" Interval="10000" OnTick="Timer1_Tick">
<input type="hidden" runat="server" id="hidCurrentDate" value="" />
<input type="hidden" runat="server" id="hidTripIds" value="" />
<input type="hidden" runat="server" id="hidTripDetails" value="" />
<asp:UpdateProgress ID="uprogTrips" runat="server">
<span style="display: block; text-align: center">
<p style="font-family: Verdana; font-size: larger; font-weight: bold;">
<img src="../../Images/ajax-loader.gif" alt="Processing..." /><br />
<br />
<asp:UpdatePanel ID="upTripsGrid" runat="server" UpdateMode="Always">
<asp:GridView ID="gvAllTrips" runat="server" OnRowDataBound="gvAllTrips_RowDataBound"
OnPageIndexChanging="gvAllTrips_PageIndexChanging" AllowPaging="true" AutoGenerateColumns="false">
<PagerSettings Mode="NumericFirstLast" PageButtonCount="35" Position="TopAndBottom" />
<PagerStyle CssClass="GridPager" />
<asp:AsyncPostBackTrigger ControlID="Timer1" EventName="Tick" />
<asp:AsyncPostBackTrigger ControlID="ddSortBy" EventName="SelectedIndexChanged" />
<asp:AsyncPostBackTrigger ControlID="ddFilterBy" EventName="SelectedIndexChanged" />
<asp:AsyncPostBackTrigger ControlID="cbPageOptions" EventName="CheckedChanged" />

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);
hidTripDetails.Value = hidTripDetails.Value + " <br/> " + ("Trip name-" + tripSummaryBO.tripName + " was modified by user " + tripSummaryBO.tripLastEditedBy);
cnt = cnt + 1;
