View 2 Repliesi 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 read several post on the TreeView is not/partly working with the UpdatePanel, but none of them mention that an update (triggered by a timer) causes creation of multiple javascript functions in the HTML header. In Mozilla Firefox this a memory leak. I have created a test webapplication to demonstrate the issue we encounter.

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 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.

I am having a weird issue with the update panels. I have an update panel in UpdateMode = Conditional . I have a dropdown list and a grid view..the gridview has to be updated ÖnSelectionChanged event on the dropdown.
The issue here is on changing the selection on dropdown, the onselectionchanged event is triggered, new data is grabbed, bound to gridview..but does nt update the update panel even after the updatepanel.update();

I am having a treeview in Masterpage,all tree items are associated with different page,when i click on any of the tree item,i the respective page should be displayed in the ContentPlaceHolder of the masterpage without postback,
i kept the treeview and the contentplaceholder in the updatepanel,still it is not working,means entire page is posting back to server

<form id="form1" runat="server">
<div>
<table>
<tr>
<td valign="top">

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 have UpdatePanel with a grdiview inside. I want to take values from the gridview and put them in TextBox out side the UpdatePanel
View 1 RepliesI 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.

I am also facing problem with Ajax Update panel. I want to refresh only the area placed under update panel. on clicking refresh button is it possible?
View 2 RepliesThis 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.
View 3 RepliesI'm having trouble getting a RadioButtonList to correctly trigger the OnSelectedIndexChanged command. I've set AutoPostBack to true, and I've registered the control for AsyncPostBack. It triggers once, but then it won't again.

I have used update panel for my aspx page. I have 4 fields in update panel
- item code, item name, quantity,price
On Item Code changed i have implemented AJAX call to get Item name and price from DB.
I want to remove quantity field from async postback, so that it remains unchanged when AJAX call has been made.
i have a Textbox and a few update panels. But each time the update panel clicks, then the focus on the textbox is gone So for example, we all know that when a user clicks on a textbox, there will be a blinking | symbol. But each time my panel updates, the focus on the textbox goes. Does anyone know how i could keep the focus on? as in, each time there is an update, still keep that textbox | symbol blinking.
