AJAX :: Postback Does Not Reset Meta Refresh Tag?

Feb 25, 2010

I have a kiosk application that uses master pages. There is a refresh meta-tag on the master page (or I can add it programmatically using Page.Header.Controls.add(metaTag), it makes no difference for my problem). When the user does not interact with the aplication it should return to the default page. But when the user does react using async postbacks only a partial postback is performed which does not reset the html meta refresh header, so it just keeps on ticking and after x seconds the page redirects to the default page. How can I avoid this from happening. The meta-tag can not be in the updatepanel so even though I can manipulate it from the code-behind when the async postback happens, any changes I make (for example sometimes when the user makes a mistake he should be redirected to a clean version of the page he is currently on after showing a modal message, so I have to change the url of the meta-tag content to no longer use the default page, but the current page) are not implemented.So the main question is, how can I manipulate (or reset in case of refresh meta tag) meta-tags in an async postback ?

AJAX :: How To Trigger Updatepanel Postback From Another Updatepanel

Mar 4, 2011

I have a web user control with one updatepanel (pnlUpdate_2), some controls and one apply button. I display the web user control as a modalpopup in my default page. In my default page i have an updatepanel (pnlUpdate_1) with a gridview and I modify that gridview with the apply button of the web user control. The web user control is for made a custom search of the gridview data. I have a problem with both updatepanels. If I set the updatemode as always in one of them (pnlUpdate_1) and the other as conditional (pnlUpdate_2), the pnlUpdate_1 make a postback in the pnlUpdate_2; I'm not an expert on this but I think that's why the pnlUpdate_2 disappear and reappear after postback of some controls in that updatepanel (not the apply button, it close the modal after postback). I try all the combinations and the problem persists. So I put both updatepanels as conditional and in some way it works; now the problem is that when I click the apply button in pnlUpdate_2 to modify the gridview in pnlUpdate_1 the pnlUpdate_1 not made the postback I get the pnlUpdate_2 postback when I use some control inside the pnlUpdate_1.

How can I postback the pnlUpdate1 from pnlUpdate_2 with the apply button?

Maintaining Scrollbar Position And Div Tag State On PostBack?

Feb 26, 2010

I have a web page that regularly refreshes on post back, and all of this works fine. However, a user has made enhance the page, which I need with:

1) There are 3 asp.panels on the page, which are scrollable vertically. When the page refreshes, the scroll position returns to the top. The enhancement is to maintain the position of where ever the scrollbar is on postback. How do I keep the scrollbar position on post back?

2) Within each of the panels are dynamically added web controls. These web controls contain gridviews, which are themselves contained inside div tags. These div tags can be hiddened and made visible by an image button. This hidden and visible state is actioned by some javascript on the page. Again, the user has asked how it is possible to maintain the state of these div tags on post back, i.e. those that are closed and those that are visible. Currently, the state is on postback for all the div tags to be visible. How do I maintain the state of the visibility of a div tag during postback?

AJAX :: Forcing Full Postback In UpdatePanel

Apr 19, 2010

I have basically the following structure set up :


I am aware that a FileUpload requires a full page postback. I read the article http://www.4guysfromrolla.com/articles/090209-1.aspx[^]I tried to install a PostBackTrigger programmatically to get a full postback only on the ImageButton1 control. All other postbacks must be partial. (GridView sorting, paging, ...)In code behind I do :


The above code does not seem to install a full postback only for the ImageButton1, so the file upload fails. How can I make this work ?

AJAX :: UpdatePanel Postback And Resulting ViewState?

Sep 10, 2010

I'm reading about the UpdatePanel and how it interacts with controls inside & outside of it.

My understanding is that the usual ASP.Net pipeline takes place when posting from within an UpdatePanel-- Page load etc all fire off as normal-- except when the prerendering stage is reached. In that case the ScriptManager does a final check and only renders those controls within the UpdatePanel and skips the rest. That's my understanding at least.

Sounds good, but for argument's sake let's say I have a TextBox located outside an UpdatePanel. If a postback occurs from within that panel, the TextBox's properties can still be set in the page load method, but those changes will not take effect. (normally; it is possible to postback the entire page from an UpdatePanel)

Is that correct? What happens to that TextBox's ViewState in this instance? Is it updated based on what happened to it in the page load method or is that modification tossed out because it wasn't in the UpdatePanel?

AJAX :: UpdatePanel GridView Paging Postback?

Dec 15, 2010

I have a simple form containing a gridview that displays some records. Everything works fine but I was hoping to wrap the grid view inside an updatepanle to prevent a full postback (flickering) when paging.

It doesn't seem to matter what I try, paging always causes a full postback which causes the page to flicker. What am I doing wrong?

Here's my markup:


And here's my aspx code:


<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="true"></asp:ScriptManager>

Tab Index Reset In UpdatePanel?

Jan 3, 2011

I'm currently having an issue where an updatepanel does an async postback and loses the tab order when the partial postback occurs. When you run through the tabs the tab order works correctly, but then you press a button and the partial postback occures the tabindex is reset. Is there any non-javascript solution to this. If not, what would the javascript solution be?

AJAX :: Margin On Div Removed After Async Postback With UpdatePanel

Sep 15, 2010

I have a series of div's inside an update panel, these divs have a margin-bottom defined in css. In IE8, when I do a async postback these margins are all removed. All the other styles are fine. If I turn on compatibility mode this does not happen. In Google Chrome the margins are maintained correctly after the async postbacks.

<div class="contentWrapper">

AJAX :: Textbox Not Writable After Partial Postback Of Updatepanel?

Mar 4, 2010

i got a strange problem. my project was ok before implimenting ajax. i have just implimented ajax in one page only with Tabcontainer and updatepanels only nothing else. almost all controls are devided into different Tabs with respective update panels.

mostly it is working ok. but the problem is :

1. in some controls i am not able to write anything even the control is "Enabled=True" and focus is on the same control after partial postback.

2. and as soon as i press Tab control goes to Address bar.

3. some time tab key is also not working.

here some code :


Here the Logic :

as soon as i type inception date; expirydate is automatically calculated and focus should come to sumassured. after this it should allowed to enter sumassured amount, which is not allowing to write.

As soon as i change tab and come back to original tab then i can write values normaly.

AJAX :: Timer Results In Updatepanel Gives Full Postback

Jan 19, 2011

I have a quite strange situation where I have the following code:


This gives a quite strange result: Every 5s my whole page gives a full postback. When I comment in (activate) the asyncpostbacktrigger, the updatepanel does not give a full postback. In the PlayerItems_ItemDataBound I have the following code (which, I do think, do not matter):


When I create a NEW updatepanel, ItemsUpdatePanel1, it does not fire a full postback without the timer. I can even start copying items from ItemsUpdatePanel to ItemsUpdatePanel1, and suddenly the full postbacks happen. I tried 2 seperate times, and they started happening at different times. I simply want the UpdatePanel NOT to give a full postback, even without a timer.

AJAX :: Button Not Preserving ID After Partial Postback In Updatepanel?

Oct 8, 2010

I've created a dynamic button from another control outside of the update Panel. The button is given an ID and such. When the button is click, a postback occurs and I've re-created this button during Page_Init, Page_PreLoad, and Page_Onload and NONE of them is preserving the value.

The only way for me to find the control was to look at the Page.request.form's allkeys and compare the string with a any text string that contains: Button. Because I ID'd teh button as: ButtonRow_0Col0. But the actual ID is null. However, when traversing through page.request.form, the allkeys shows that ID with no problem.

So how come the actual ID is lost after a partial postback yet, the page.request.form's allkeys can pull out its allkey's value??
