C# - Update A NET UpdatePanel From The Code Behind With No ContentTemplate?
Jan 13, 2011
I know that you can call an update on an UpdatePanel server side by calling the Update function on it. I have done this in the past, though in the past I also had a ContentTemplate. In one of my current projects I add all of the controls to a the UpdatePanel in the code behind so there is no ContentTemplate defined. Is there a way to update the UpdatePanel from the code behind despite this, or am I barking up the wrong tree?
<asp:UpdatePanel runat="server" updatemode="Conditional">
<ContentTemplate>
<asp:PlaceHolder runat="server" />
</ContentTemplate>

i have a website with three UpdatePanel Control and inside of each UpdatePanels has ONE Gridview and a SqlDataSource Control.
all gridviews are connected to its own SqlDataSource Control. so technically when i run my website all gridviews automatically get their data from their respective SqlDataSource Control and display them accordingly.
but what i need to do is instead of letting all the update panels to load each gridview their data upon Onload event, i need the updatepanel to update on queue, (Technically changing the UpdateMode to Conditional does not solve my problem.) there will be an event which will trigger the updatepanel to update later.

I have a script inside an updatepanel. This script needs to be inside the updatepanel as it must be located in that spot.
Now when we click the "LinkButton" to update the updatepanel, the script will dissapear.
It seems that the script only is initiazed on the first Page_Load and Refresh of the page.
How can we keep it when pressing the "LinkButton"?
Complete code is below:

i am using a TabContainer and at each TabPanel i have embed an UpdatePanel in order to update each tab alone.
this is my code:
[Code]....
the problem is that it makes several seconds to update each tab (the same time for every tab) and i asume that this is happening because it updates all the TabContainer and not the selected Tab.

I am trying to trying to setup an updatepanel to update every X seconds, the problem is I don't want the control to actually refresh unless there is new data. So I currently have a child updatepanel in a parent UpdatePanel, the child updatepanel gets refreshed by a timer. But I can't seem to find a way to trigger the parent panel to update. Again, only when certain conditions(data changed) are met.
Sample Code:

I have two updatepanels on my site (upanProfileSearch and upanMemberList). When I hit the button in the upanProfileSearch it should bind the Data Items in the gridview in upanMemberList and here make a RowFilter on the text in upanProfileSearch. When I make a run to curser, I can see, it happens. It makes a RowFilter. but it doesn't update the gridview. Can anyone tell me why it doesn't update? I have UpdateMode="Always" and RenderMode="inline" on both UpdatePanels.

I've exempted the irrelevant bits of code. Essentially, I am trying to change the URL of an image control inside of an update panel inside of a custom user control from a function called inside an update panel from my main page. Using UpdatePanel.Update() isn't working: I end up waiting for the next full page POST to occur before all the updates I make to CustomControl from buttons within the main page's update panel are visible. I verified that Update() was being called via the debugger: there are no issues in that department.
Here, you can see Custom Control and the Button declared. The button is in an update panel to avoid giving a full POST and causing the whole page to reload.
<cust:CustomControl runat="server" ID="CustomControl1">
<asp:UpdatePanel runat="server" ID="UpdatePanel1"> <ContentTemplate>
<asp:Button id="Button1" runat="server" OnClick="DoStuff" />
</ContentTemplate> </asp:UpdatePanel>
This control stores images within their own seperate update panels because rerendering the images is very slow (it requires processing arrays of millions of datapoints) and the user only ever needs to modify one image at a time. I'm using Image1 as an example.

If yes then I will check all things again..

i have a Databound Accordionmenu with hyperlinks in its content template. What i wanna do is adding `onMouseOver` animation to these hyperlinks. Normally i would do somthing like :
[Code]....
where the playanim javascript function triggers the animation for the hyperlink. But the thing is, Hyperlinks in the content template are not visible in code, they simply dont exist. when i write the code, it says there is no item called hyperlink1, it doesn`t show up in the intellisense menu either. Is it possible to add an animation inside an Accordionmenu, if yes how can i reach the TargetControls inside the ContentTemplate to trigger the animation.

lets say I've got a function that iterates over an array. The function is outside the updatepanel, the array is defined within the update panel. The items of the array are dynamically created. On the first try I've realized, that the values of the array do not update when the update panel loads again.

Here is my code:

<asp:CheckBox ID="cbShowText" runat="server" Text="Show Some Text" AutoPostBack="true"
OnCheckedChanged="cbShowText_CheckedChanged" />

I'm trying to do a number of large queries in the same routine, and have a label in an updatepanel update after each one. I must be doing something wrong, however, because whenever I fire up the routine, my label won't update until the last query is done. Isn't it possible to do UpdatePanel.Update multiple times in the same routine/event? This is the code I'm using:
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click
lblStatus.Text = "Busy with task 1"
UpdatePanel1.Update()
LongTask()
lblStatus.Text = "Busy doing task 2!"
UpdatePanel1.Update()
LongTask()
lblStatus.Text = "Done!"
UpdatePanel1.Update()
End Sub
Private Sub LongTask()
conn = New SqlConnection(connstring)
conn.Open()
cmd = New SqlCommand("Select * from very_large_table", conn)
cmd.CommandType = CommandType.Text
reader = cmd.ExecuteReader()
End Sub
When the form loads, the lblStatus is emtpy. When I click the button, I see the page loading until it displays 'Done!'. I don't see the other texts. This is the page source:
<%@ Page Language="VB"
MasterPageFile="~/MyApp.master"
AutoEventWireup="false"
CodeFile="test_page.aspx.vb"
EnableEventValidation="false"
Inherits="test_page"
title="MyApp"
Theme="DefaultTheme"
%>
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:Label ID="lblStatus" runat="server"></asp:Label>
<asp:Button ID="Button1" runat="server" Text="Update!" onclick="Button1_Click" />
</ContentTemplate>
</asp:UpdatePanel>
</asp:Content>
The page has a masterpage that contains the neccesary Scriptmanager.

I have an UpdatePanel with a MultiView inside. I am using jQuery to call the server to run some logic and based on it, change the view in the MultiView. The problem is that the updatepanel is not getting refreshed.
My UpdatePanel:
<asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="false">
This is my call to the server:
[code]....
When the page loads again, the multiview is not showing the assigned view.
I have noticed that the call to the server doesn't set Page.IsPostback = true, it remains false. Perhaps this is somehow related?

I am dynamically ading the following to an UpdatePanel
Tab control which has X# of Tabs, each Tab has a various labels and a Rating Control.
When the user hits the Rating contro, the RATING_Changed fires and runs a stored Proc to update the DB. I want the Panel to then display the newest information back from the DB. I can't seem to get the last part to work. I'm still learning .NET so i may have missed somethign easy, but i've tried setting AutoPopstback, using Triggers, etc.
The DB Update does take place but the NEW contents are not displayed

I am using an updatepanel. Inside this updatepanel I have a LinkButton with the clickevent below.
When clicking this button the Image does not update to a new image. As seen I am assigning the Session variable a new Image path(Session["showThisImage"]) which I am getting in the Page_Load event.
Now I am putting this path in a public variable that is set to the HTML control "Img1" with help of Page.DataBind().
However the Image does not change which is the problem, the image is still there. But other things as labels, links etc do get updated with new data which I haven´t put in this example which means that the updatepanel works except changing the Image here? Also to mention is that if you uncomment: "Response.Redirect("ThisPage.aspx");" the image will change but this will mean a FULL postback which I dont want.

This sounds weird, but I would like to NOT update a control that's within an update panel. Is this possible? basically the way facebook works, facebook controls are rendered on a "get" command. but I have controls within the same update panel that cause AJAX postbacks. When the postback's happen, I lose my facebook server-side controls. I am wondering if I can "unregister" a control from an update panel? Or do I just have to redesign that page.
