Conditionally Trigger A Full Page Postback From A Link Button Inside Update Panel
Nov 29, 2010
How do I conditionally trigger a full page postback from a link button inside of an update panel?
I have a custom control that contains its own updatepanel with a link button nested inside of it. When the link button is pressed I want its event handler to have the option of either letting the control update as normal or doing a full postback on the page.
Here is the control hierarchy:
Page
Custom Control
UpdatePanel
LinkButton
Event handler Pseudo code:
LinkButton Click Handler Begin
If is a partial post back AND a full postback is needed
Page.DoFullPostback
End If
End Handler
Note: I aways need the partial postback to happen. I was considering injecting a __DoPostback in the controls markup but this seems hacky to me.

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.

Is something like this possible?
Dim iCounter as Integer
Dim iQuantity as Integer = 10
Protected Sub btnFoo_Click Handles btnFoo Yadda
For i as Integer = iCounter to iQuantity - 1
//do something with AsyncPostBackTrigger until iCounter = iQuantity - 1
//then trigger a full postback
Next
End Sub
I am new to the concept and feel like there must be something really easy that I am missing.

I have a link button inside an update panel. The problem is the link button on postback is updating the whole page. Tried it with a normal button and the page is not refreshed all. Here's the code.
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">

I am having an issue with an update panel, which is still causing the entire page to postback.
I have made sure i have all the correct bits in the web.config, section groups, httphandlers, httpmodules, additonal assemly etc... but it still does not work. I have got it to work in a way,which is why i think i have the config right, because if i take the search panel of and place it outwith the update panel, the go button only postsback the rest of the page not what is inside the updatepanel.
I am using a master page, but the update panel only appears in the content page, within the content tags.

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 have a link button inside a template field of a gridview. The gridview is wrapped in an update panel. I want the link button to fire an async postback but it always fires a full postback. Why is this?
This is a similar problem to the one described in the link below. However, I have tried doing a RegisterAsyncPostbackControl in the gridview databound, but this did not work.

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)

I'm manually triggering an update panel refresh using javascript (long story- but it has to be this way), but I still see a page flicker outside of the update panel, so I'm concerned that the whole page is getting refreshed rather than the update panel. Any way I can determine this? Perhaps some value in the code-behind on the postback? Or some client side trick? If the jQuery $(document).ready() event fires, does that mean the whole document is refreshing or just the update panel?

Here is my requirement -
1. I need to load a user control on link click event of a link button during postback of aspx page.
2. On button click event of a save button on that aspx page, I need to read the selected values from that user control on further postback.
If I write the loadcontrol code in link_click event, the control is not recognized at all in the button_click event. When I shift it to page_init and execute only during not postback, the user control loads with default values.

I have an application that allows users to insert data into a log. The forms are displayed inside update panels and display via modalPopUpExtenders. I am running into a problem where users are able to click the Insert button multiple times before the panel can update that a click was registered.
How can I disable the Insert button once the user clicked on it and had time to communicate with the server? The system is allowing duplicate and triplicates to be inserted into the system.
