I am using an updatepanel and a grid is placed within the same.Now,I have a checkbox corresponding to each row of the grid.If I check it,say corresponding to one row and click a button(placed outside the panel), a popup will be opened which is a separate aspx page having its own functionality.
The requirement is like I need only the panel to refresh not the whole page.
I want handle exceptions in update panel control with c#.
View 1 RepliesI have a few Link Buttons on my AJAX enabled page, all basically the same:
[Code]....
Here's the OnClick method they're attached to:
[Code]....
I ensure these LinkButtons trigger Async in my Page_Load method:
[Code]....
Then on the page there are three UpdatePanels (as called in the btnCampus_Click method). All are similar to this (only the ContentTemplate changes):
[Code]....
why the UpdatePanel's aren't triggered when clicked. I've been using UpdatePanels for a long time, but I can't seem to figure this one out.
Here is the sample code am trying.
<div>
<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="true" />
<div>
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="conditional">
<Triggers>
<asp:PostBackTrigger ControlID="Button1" />

This upload is working. But why the page is getting refreshed? this is not partial post back and instead it 's full post back. i have read the articles for the fileuplaod with issue inside the update panel. is there any way to achieve this asynchronous upload on button click?
I don't want to use the Ajaxtoolkit Asyncupload because that will upload (Ref : [URL] ....] the moment when we seelct the file itself which i don't want to do that. i need to do on the button click event.
I have two controls, each placed in their own <div> and <UpdatePanel> on my form. I am having trouble getting the partial page postback to fire after the file upload has completed. I have not used the __doPostBack approach before so I'm not sure if I am heading in the right direction.
View 6 RepliesI am having issue with my ModalPopUpExtender's OKControlID. I have a button inside an update panel that should do AsyncPostBack. The button works fine and runs server side code but it causes full page postback. How do I solve this issue? I want the 'OK' button inside the modalpopup to call the serverside code and update Label control 'label3' without causing the page flash. Given below is my code;
MarkUp:
<html xmlns="http://www.w3.org/1999/xhtml" >
<head id="Head1" runat="server">
<title>Next Gen Web Browser</title>
<script src="http://ajax.microsoft.com/ajax/jquery/jquery-1.3.2.js" type="text/javascript"></script>
[Code]....
When I browse to my page that has the modal popup panel on it, the panel initially is visable, and when I do a postback it acts as intended. let me know if you need the master page....

I have a web app which implements IHttpAsyncHandler for handling web service calls asynchronously, done according to this web page:
[URL]
Now, my page is rather complex with many update panels, so when I initiate the AsyncHandler with BeginProcessRequest, the page does a partial postback, then when EndProcessRequest is called, another partial postback, everything is fine so far...
But when I navigate around my page and causes a partial postback between BeginProcessRequest and EndProcessRequest, nothing gets updated when EndProcessRequest is called...
In debug, EndProcessRequest IS CALLED in the server codebehind, but nothing updates clientside... I'm not even sure if it even caused a partial postback...
I'm a pretty big noob when it comes to this Async stuff, and I just followed the site above, so I'm guessing it maybe something behind the principle of how IHttpAsyncHandler works.
I am working with a user control which is inside an UpdatePanel. The user control uses swfobject to add a flash object to a div in the user control. Part of the functionality of the user control is it allows the user to change 'channel'. The channel is set and handled in the code behind hence the call in the JavaScript below to <%=channel%>.
The problem I have is that when the new channel is saved, the JavaScript code below is still pointing to the old channel. The only way I can fix this is to refresh the page via the code behind, but I'm thinking there must be a better way to do this..

I am trying to use LinkButtons with the DefaultButton property of the ASP.NET Panel in an UpdatePanel. I have read and used the various other answers that are around describing the wiring up of the click event so that a full postback is not done instead of a partial postback. When the page loads, I wire up the .click function of the LinkButton so that the DefaultButton property of the ASP.NET panel will work.
This all works fine, until you bring an UpdatePanel into the mix. With an UpdatePanel, if there is a partial postback, the script to wire up the .click function is not called in the partial postback, and hitting enter reverts to causing a full submit of the form rather than triggering the LinkButton.
How can I cause javascript to be executed after a partial postback to re-wire up the .click function of the LinkButton? I have produced a sample page which shows the problem. There are two alerts showing 1) When the code to hook up the .click function is being called, and 2) When the .click function has been called (this only happens when you hit enter in the textbox after the event has been wired up). To test this code, type something in the textbox and hit Enter. The text will be copied to the label control, but "Wiring up Event Click" alert will not be shown. Add another letter, hit enter again, and you'll get a full postback without the text being copied to the label control (as the LinkButton wasn't called). Because that was a full postback, the Wiring Up Event Click event will be called again, and the form will work properly the next time again.
This is being done with ASP.NET 3.5.
Test Case Code:

I have a JavaScript slider which calls the follow functions:
var prm = Sys.WebForms.PageRequestManager.getInstance();
prm._doPostBack('ZoomButton1','');
The ZoomButton1 is tied to an UpdatePanel and does a partial postback. In this case, when the Slider is constantly be dragged left and right, the value is changing/updating and JavaScript is hammering the postback extremely fast. It is so fast, the server sometimes but not always reports a pagerequest manager error, I believe.
I know that I can set it to just update my data (updatepanel) on a button_release or a mouse-up.. but occasionally, I still encounter the pagerequest manager error.
i got a strange problem. my project was ok before implimenting ajax. i have just implimented ajax in one page only with Tabcontainer and updatepanels only nothing else. almost all controls are devided into different Tabs with respective update panels.
mostly it is working ok. but the problem is :
1. in some controls i am not able to write anything even the control is "Enabled=True" and focus is on the same control after partial postback.
2. and as soon as i press Tab control goes to Address bar.
3. some time tab key is also not working.
here some code :
[Code]....
Here the Logic :
as soon as i type inception date; expirydate is automatically calculated and focus should come to sumassured. after this it should allowed to enter sumassured amount, which is not allowing to write.
As soon as i change tab and come back to original tab then i can write values normaly.
I've created a dynamic button from another control outside of the update Panel. The button is given an ID and such. When the button is click, a postback occurs and I've re-created this button during Page_Init, Page_PreLoad, and Page_Onload and NONE of them is preserving the value.
The only way for me to find the control was to look at the Page.request.form's allkeys and compare the string with a any text string that contains: Button. Because I ID'd teh button as: ButtonRow_0Col0. But the actual ID is null. However, when traversing through page.request.form, the allkeys shows that ID with no problem.
So how come the actual ID is lost after a partial postback yet, the page.request.form's allkeys can pull out its allkey's value??
I have a Panel, which contains some form elements and is Visible=False on page load. When a button is pressed the Panel is made visible (the button and the panel are inside the same UpdatePanel). I have a PasswordStrength control within this Panel and on Safari it does not work once the Panel is made Visible=True. All other browsers work perfectly.
I've tried adding the PasswordStrength control at runtime but the same thing happens...
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 used jQuery to invoke an AJAX webmethod in c#. This webmethod runs a query and stores the resulting information in a session variable. I have a gridview that has an objectdatasource that uses the session variable with the selectmethod to then populate the gridview with data from a query. I need the final piece to get the gridview to databind() again with the new value.
So click map, update gridview. However, maybe I'm going about this all wrong. In essence, take javascript variable, push to ASP.NET in C# and refresh gridview on page with new data from query.
I have a simple form (textbox, submit button) which is wrapped in an update panel.
[Code]....
I type some text in the textbox, click submit, then the server creates a database record and returns an object, which has properties like ID, Name, URL, Blah, etc. These are the values that the script requires.
So if i were to call a web service from the client-code, in order to get the values that were just created, i would need to do some hacks (get last record modified that has the value of the textbox). Not ideal, and neither is two AJAX calls for one form post. (update panel postback, then web service call).
I have a linkbutton inside a updatepanel and when the update panel does a partial page rendering, the linkbutton disappears.
<asp:UpdatePanel ID="up" runat="server" ChildrenAsTriggers="true" UpdateMode="Conditional">
<ContentTemplate>
<asp:DropDownList ID="drp" runat="server" AutoPostBack="true" CausesValidation="true">
<asp:ListItem Text="" Value="" />
<asp:ListItem Text="a" Value="a" />
<asp:ListItem Text="b" Value="b" />
<asp:ListItem Text="c" Value="c" />
</asp:DropDownList>
<asp:LinkButton ID="link" Text="abc" runat="server" />
</ContentTemplate>
I think that is because the link button is rendered using a script and that script is not run after the post back.
I 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.
