I have an update panel in a user control and I am adding multiple instances of it for example 5.
When that update panel refreshes the page load occurs 5 times.
How can I prevent it only for once?
I have a user control, that has an update panel and update progress control in it.
I use this user control in more than 1 location on the same page.... problem is, when ucA posts back, I see the update progress control for both ucA and ucB. I assume this is because it is a user control and the update panel and progress are named the same?
Either way - how do I make it so that the update progress only displays for the proper user control?
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 used UpdateProgress below is code
<asp:UpdateProgress ID="UpdateProgress1" runat="server" AssociatedUpdatePanelID="upT">
<ProgressTemplate>
<div class="modal">
<div class="center">
<img alt="" src="loader.gif" />
</div>
</div>
</ProgressTemplate>
</asp:UpdateProgress>
this is for just 1 updatepanel I have 6 updatepanel in my page how I can use UpdateProgress for all my update panel?
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 have built a User Control in VB which displays two gridviews and allows a user to select an item in the first gridview and display multiple rows in the second grid with the key of the selected item from the first. The data to be displayed is passed to the User Control as a datatable object via a public property of the User Control.
The user control works perfectly, but to allow the the subs in the codebehind of the User Control to access the data set when the user control is initialised, I have declared them as "Private Shared".
Having got everything to work, I now want to display multiple instances of the same User Control with different datasets.
However, because my data objects are defined as "Private Shared" each instance of the user control is overwriting the data of the others.
I can fix this problem by removing the "Shared" keyword, and have also tried setting them to "Protected" instead but then my variables expire after being set and contain "Nothing" when I get to the "RowCommand" event in the Code Behind.
I'm sure I must be doing something stupid, because surely the whole idea of User Controls is to make reusable code drven by parameters.
Here is my code:
Main Program .aspx
[Code]....
Main Program Code Behind
[Code]....
User Control .ascx

I have this Web User Control, with 3 controls:

In code behind:

When I try to add two UserControl and I Click in btnSearch of second UserControl, txtSearch.txt returns value of first User control.
How I can get the value of second txtSearch?
i have a site, Masterpage --> content pages,
So as we anvigate between contnet pages i would like to have so nice JS effects, like loading icons, non page refresh.
from what i can understand i will not be able to dynamicly load the content pages using Jquery and this results in a page flash as new pages are renderd.
I could change the conent pages into user controls, how can i use jquery to load these dynamicly or use a update panel.
I have a requirement like need multiple update panel in web page and also i want to load only one (targeted one) update panel content when I click button on another update panel.

I've created a User Control (.ascx), which has a dropdown. When an item is selected, it uses some model classes to pull back a set of data which it then dynamically displays as a list of checkboxes in a panel control.
When I add one to the page, it works very well indeed.
However, when I add another I get this behaviour:
1. Select an item from the first dropdown, the checkboxes appear underneath ok.
2. Select an item from the second dropdown, the new lot of checkboxes appear ok, but the first lot disappear.
It's rather frustrating, they both have different IDs on the page, so they shouldn't interfere with each other should they? There is some Javascript that I've added but I use the Panel.ClientControlID to separate these out (I've already thought of that one).

I am trying to wrap my head around update tabels, the thing thats boring me is if i should use one or multiple panels. When i load a control into my update panel should that control have it's own update panel? Or will it use the updatepanel it's loaded into? Is it even possible to dynamicly load a control into an updatepanel and do async post backs from there? Let me paint you a picture:
Index.aspx >

In my default.aspx page I have a PlaceHolder control within an UpdatePanel. In this placeholder control I will dynamically load a web user control, which is just a form with a submit button. On this user control, I have the form within an update panel and I have the "Submit" button's Click Event added to the triggers.
When I submit the form, the UpdatePanel on the web user control nor the update panel on the default.aspx page are capturing the post back, thus causing a full post back which refreshes my page.
how to capture this post so its rendered in Ajax and not a full post back?
I have a script manager and 3 update panels on my page. I am not very familiar with AJAX but I would think anything in the contentTemplate would not cause a postback and page reload, but they all do, here is the outline of the SM and UpPanels

<div>
<asp:ScriptManager ID="sm" runat="server" />

When i click on the Search Button OR the Count Button, i get BOTH error messages - why ? I should only get one error message.

Below 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 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.
View 1 Replies am using a master page, with children pages.
I am using forms authentication, and a session object to hold user information once the user is authenticated.
I am able to login and log out. I am able to log in and use the "remember me" functionality of the forms authentication.
When attempting to test the "remember me" functionality, the master page load event contains code to check the forms authentication & remember me, and retrieve user info from the database to automatically log the user in. This fires correctly, and the screens all load with the user successfuly logged in, and the users info is successfully stored in a session object.
Without touching anything on the screen, a moment passes and then the master page load event spontaneously fires again, Page.User.Identity.Name still contains the user name, however the session variable is now null, and throws an error.If I tell it to run past this error, it does, and the application continues to function normally, withthe session variables set correctly.
Its almost as if that second firing is ina different session, or something.
I have no problem posting code, but I have a profile class holding / handling the session communication, etc so it is a bit cumbersome.
