I have put several buttons and panels in my update panel. I also have a script manager on that page. now when I click on any of the buttons then the functionality is working fine but problem is that the complete page gets reloaded witha a flick, instead of updating the update panel only. I have set the "children as trigger" property of update panel "true".
View 1 RepliesBelow is the sample code on using the update panel. The page just has a button and a label. On button click it updates the label with the server time. Though the label is inside the update panel the page goes for a complete postback. in understanding why it is behaving like that. I tried the options of Updatemode, using different script references nothing seems working for this simple application.
-- aspx page
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
I'm using the same thing on different page and it works fine in there, but on this specific page, this is not working.
Here's what I have:
<asp:UpdatePanel ID="upMain" runat="server" UpdateMode="Conditional" Visible="true" RenderMode="Inline">
<ContentTemplate>
<asp:DropDownList ID="ddlNewService_PortTelco" runat="server" Width="250" CssClass="dropdown" AutoPostBack="true" OnSelectedIndexChanged="Provision_PortedTelcoChanged"></asp:DropDownList>
</ContentTemplate>
</asp:UpdatePanel>
On the way before the DropDown there is one DIV (html one), and then few asp:Panels.
I am using nested gridview from [URL].
I follow this link [URL] .... to solve my problem.
Your code is useful and perfect for me.but my gridview and button are inside update panel.
So Nested Child GridViews is not remain Expanded on postback. Where should I need to do change to remain child gridview epanded on postback.
I have a user control with linkbuttons (used for paging) and a repeater inside an update panel. The paging works correctly, but is causing a full page postback every time I click through to the next page.
The update panel looks like this:
[code]....
So far, I have tried adding an async postback trigger for the user control, which does cause an async postback but does not update the rest of the text in the update panel. In otherwords, the async postback occurs and the next page shows up, but the original text in the repeater is there as well just below it.
I have also confirmed that I have IDS set on my linkbuttons, since that can trigger a full postback inside an update panel.
I have tried changing the update panel mode (Always, Conditional, ChildrenAsTriggers, etc.).
None of it makes a difference - the only thing that actually causes an async postback is to use the trigger, but then the rest of the content in the update panel is not updated, so I get duplicate content.
i have one label out of update panel and one button inside update panel. in button click event i update the label text. when i run the code and click on button then partial postback occur and button click event fire but label value is not change. if i put the label too in the update panel then label value change at the time of button click. i do not understand why label value is not getting updated. suppose if i want that label should stay out of update panel and label value should change at the time of partial postback then how to write the code. i dont want put the label in any update panel.

I have a gridview that putted in ASP.NET Panel. both of panel and Gridview are in an UpdatePanel. there is a column in gridview that Causes Partial PostBacks. i want to Maintain Panel Scroll position on those postbacks.
View 1 RepliesI have a GridView control inside one Update Panel and a detail section inside another Update Panel. Initially, the detail section is hidden and when a GridView row is selected, the Detail panel becomes visible. Everything works fine except that if the GridView contains more rows and covers most of the user's screen, screen doesn't shits to the start of Detail section.I can use anchor but was just wondering if there is any other way of achieving this. Also the Detail section has multiple nested Update Panels and if I use anchor, then any of the child Update Panel's update will move the screen to the beginning of the detail Section.

I have a website where different comapny and users can login. Till now I have not seen any issue on IE 6. But in case of one account, when try to login the website, users are getting security information "This page contains both secure and non-secure items.
I can reproduce the same easily for the same customer but not happening for any other customer. I have "ReportViewer" control (gets rendered as iframes) on the page.
In this scenario, whether user selectes "Yes" or "No" button, the home page with charts loads 30% and other controls remains invisible. Though I see same out in "View source" for this and other customers. We dont change anything much then the data and charts for the users. We use https for this website and has few links with "http" in page. But then this is same for all the users, but it happens only in case of one customer.
i have a dropdown list
<asp:DropDownList ID="DDName" runat="server" AutoPostBack="True"
DataSourceID="sdsName" DataTextField="Name" DataValueField="name_ID"
Width="179px">
</asp:DropDownList>
the problem that it is not causing post back on the first selection but on the second, I mean if i select from drop down list first selection no post back on the server,but when i select another item from the list (the second click on a different list item )
So I have two UpdatePanels. I am dynamically creating server-side buttons in UpdatePanel2. When the buttons come out, they are not hooked to the asynchronoustriggers of updatePanel1.
So how can I dynamically add these triggers of these newly dynamically created buttons so that clicking these buttons will only cause a partial postback to UpdatePanel1 ? Right now, when I click these buttons, it causes a partial-postback refresh to UpdatePanel2 (the panel itself that which the controls reside in)
I have one UpdatePanel which contains search criteria controls for a GridView.
The GridView is in another UpdatePanel.
I have a reset button in the search criteria UpdatPanel which resets all the search controls to their default values. However when I click this button for some reason my GridView RowDataBound method fires.
This is slowing the page down when the reset button is clicked. Does anyone know why this is happening and how to stop it. I haven't posted the code and explained it in plain english for ease of reading.
I have a gridview which has a checkbox column which are set to automatically postback. When a checkbox is clicked, a partial postback occurs, and the associated record is displayed to the user (this is the required function).My problem is regarding when a user clicks a number of checkboxes in quick succession. I have got ajax request queuing working fine, so each checkbox postback is eventually dealt with. However as the gridview also postsback, it resets its viewstate on which boxes are checked, removing some of the boxes which the user may have checked.I've attempted to take off the viewstate on the gridview which seems to achieve nothing, neither does placing the gridview in a separate update panel.

Anyway, on the inner grid I am allowing the user to delete rows.However when the page posts back I am unable to reopen the row that was opened. I have tried the RegisterStartupScript, etc. in the code behind but am unable to trigger the event. I have tried the code behind to find the row that is expanded but that was unsuccessful also.How can I have the row expanded when the page posts back?

Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

I might just be misunderstanding, but as far as I can tell they don't really help me. How do I get this to go away without setting enableEventValidation="false"?
I dynamically add the webcontrol in onInit or onload (page_load). it will cause the second post back and with the ispostback==false;
if first enter the page is no problem. but if I click on the some button. it will trigger postback two times.
first time: ispostback = true.
second time: ispostback = false.
the second time postback caused me headache because all my value has been initialized due to the coding like below:
DataTable _temp;
if(! ispostback)
