Postback problem using a usercontrol inside an update panel that is inside a masterpage

Hi all,

I have been messing around with this all day and its starting to get on my nerves i'm probably missing something really simple but I was hoping someone could shed some light on it or perhaps point me in the right direction..

As I said in thesubject of the post, I have a user control inside an update panel, that resides in the master page, now my problem is when the user control goes to perform a post back I get that nasty "Invalid callback or postback argument error" Can someone help me to rectify this issue? Basically all the control needs to do is hide one panel inside it and show another on a link buttons click even.. There is other code in there too..

The simplified code for the master page is as follows..

<%

@dotnet.itags.org.MasterLanguage="VB"CodeFile="redcellar.master.vb"Inherits="redcellar" %>

<%

@dotnet.itags.org.RegisterAssembly="AjaxControlToolkit"Namespace="AjaxControlToolkit"TagPrefix="ajaxToolkit" %>

<%

@dotnet.itags.org.RegisterSrc="login.ascx"TagName="login"TagPrefix="uc2" %>

The relevant code behind for this is:

ProtectedSub lbForgotPassword_Click(ByVal senderAsObject,ByVal eAs System.EventArgs)Handles lbForgotPassword.Click

pnlLogin.Visible =

False

pnlForgotPass.Visible =

TrueEndSub

Some help with this would be greatly appreciated.. :)

I'm still stuck with this one :S Any ideas?

After eliminating one thing at a time in my masterpage I found that this was the culprit, commenting it out did the trick..

<form method="get" action="">
<p><label for="search">Find a wine:</label>
<input type="text" id="search" onfocus="if(value=='eg: Henschke') value=''" value="eg: Henschke" />
<input type="image" src="http://pics.10026.com/?src=images/go.gif" value="Go" id="go" /></p>
</form>

does anyone have any idea why??

Postback with MasterPage

hi all

i want to load other page with masterpage without postback

any one cane help me?

AOJ

Hi,

In my opinion, there is not elegant way to achieve this.

First of all, please note that MasterPage is quite different from a container (e.g.: frameset/iframe) in the client side's point of view. The client isn't aware of the existance of masterPage at all. Every actions fired by controls in the masterPage is the same as the one fired by control in a normal page.

So, if you'd like to implement this, what you need to do is to place a UpdatePanel on the masterPage, and load different controls into it programmatically. Then update the UpdatePanel.

Posting On Ajax Help Required.

Hi All,

My requirement is like displaying random advertisements in masterpage. I had a page with Ajax Timer control which on Timer_Tick event fetches me a new image and bind to <asp:hyperlink>, my problem is on page_load also i want to display image, but image is displayed only on Timer_Tick after some fixed 3000 seconds is elapsed. On page_load i want to display same images, my images are dynamic comes from database, i store them in a dataset, and binds to asp:hyperlink on timer_tick. Can anyone help, on how to display image on page_load, is there any way how i can attach the server side event (Timer_Tick) on page_load also, so that it will fetch me the image.

Thanks In Advance,

Karthikeyan.

Consider using the AdRotator control.

The AdRotator control selects and displays an ad randomly each time a page is refreshed.

The AdRotator control in ASP.NET 2.0 populates its image and navigation properties in 3 different ways -
Database, XML and also programmatically.

Thanks for your valuable suggestion, but my requirement is i don't want to do a postback for whole page, just for banner, what i want is to do a Asynchronous postback on fixed timer interval and change banner. First time when the page load there is no banner getting displayed. This is my problem, is there any way through which i can again call Timer_Tick event in page_load so that for the first time a image will be loaded.

Thanks & Regards,

Probblem with Menu control inside an update panel

Hi,

I have a master page with a script manager ,update panel and Content Palce Holder. in the default page which uses the masterpage I have added a menu control, textbox and a button. I have two problems which I have seen in the past in other versions of ajax. I have not coded anything other than just these controls on a page

1) I could click on button all day long and there is no java script error but as soon as I click on a menu item I get javascript error saying:

Line:221

Char:20

Error '0.cells' is null or not an object

code: 0

2) I can not get my CSS sheet work in my app theme for the background images. I have the following code in my CSS

.Menu1BackGround

{

background-image:url(/Images/Menu1_Background.bmp);

}

and I have assigned the it to the menu. Nothing happens as if it does not recognize the image path. I could add the background:black to the code and it works fine for the color but not the image. I am not sure if thisis because of the same problem.

Any body have any ideas?

Thanks

Seehttp://ajax.asp.net/docs/overview/UpdatePanelOverview.aspx#UpdatePanelCompatibleControls. The Menu control is not supported inside an UpdatePanel.

I have been using this piece of javascript to go around the menu problem:

var oldMenu_HideItems = Menu_HideItems;if(oldMenu_HideItems){Menu_HideItems = function(items){if (!items || ((typeof(items.tagName) =="undefined") && (items instanceof Event))) { items = __rootMenuItem; }if(items && items.rows && items.rows.length == 0){ items.insertRow(0); }return oldMenu_HideItems(items);} }
 

I got it from the asp:menu javascript code and I hook it to "patch" the problem.

Adding it to a page where a menu resides makes the javascript error go away.

Menu control is not compatable with AJAX.

I m also facing sme problem..

Hi Sejal,

Check this article on using update panel in master pages -

http://ajax.asp.net/docs/tutorials/UsingUpdatePanelMasterPages.aspx

You can also try using update panel triggers(not sure how it will work in master page) -
