when I click a button the content inside my updatepannel changes. The id of the button is set as a trigger for the updatepannel, so that the other updatepannels are not affected. How can I replace the buttonclick event with a page load event? Is there a way to specify the pageload javasript event as a trigger for the updatepannel?

I made a very simple pannel updating wich will query a database and show a message on masterpage through a label.
Thus, I've put an updatePannel with a label and a timer within (obviously with a scriptManager) in my site's masterpage.
However, when I try to interact with the timer1 object, I receive an error message: "object not set to an instance of an object". I not receive this message when placing the schema in a blank page (without masterpage).
I must to run the query in masterpage because the users need to receive information whatever they are in my site.
How can I correctly place the components to do this work? what I'm doing wrong?
I have an ASP.NET button. When the button is clicked, I'd like a modal popup to display after the server-side code for the button runs. I don't want to use the ASP.NET Ajax control toolkit modal popup extender.
With ASP.NET Ajax, I can hook into the end request event. Is there a way to do this without ASP.NET Ajax. just jQuery? I basically want to run some javascript after the server side click code runs, after the postback.
i have two dropdownlist (Country, and State) so when the user select the "country" the "state" will be filled.
So on postback the ajax will work, and i have some javascript function that called on thIe page load.
the javascript didn't called.
I have a page that calls a webservice from JavaScript using the approach described in this article: [URL]
This is working fine. The problem is when the page causes a postback before the end of the execution of the webservice's method. When that happens, the succeeded callback method never gets called. Does anyone know if there's a workaround to this?
A have a web page that does an AJAX callback. When the CallBack event is handled, my ASP.NET code generates some JavaScript that is then returned to the browser. The idea is that this JavaScript will then immediately be executed. The reality is that it isn't....
Here is an example of my server code that handles the callback (the JavaScript has been simplified to a single alert):
[Code]....
I've tried using some of the browser DevTools in IE, Firefox and Chrome, but I can't get them to spot changes after an Ajax event...]
I am creating a ASP.Net server control to manage locations. The control is a composite control containing several text-boxes, labels, and a link button. I use the AJAX Control Toolkit to provide a modal popup which contains a Bing map. All the Javascript is in its own file and used as an embedded web resource.
The link button is what opens the modal popup. It also needs to call a Javascript function that initializes the Bing map (onclick = "GetMap();"). There are instances when this server control is placed within an Update Panel (and there is no way to avoid this). When in an Update Panel the link button loses its onclick event. I understand that this is because during an async postback the portion of the DOM that defines the content of the Update Panel is thrown out and reinitialized, resulting in the event breaking. When the control is not in an Update Panel everything works as intended.
I have tried registering events on Page.Load and Page.Init, like so:
[Code]....
I have also tried flat out writing the function call to the page:
[Code]....
I have put breakpoints on the lines inside each delegate and they do not get hit. I am not aware of any special way to register events of a composite control's child control or the Page.Load/Page.Init events when being done inside a server control. Is there some special way to register these events? (Note: Both those code blocks above are in my CreateChildControls() method)
Below is the GetMap() Javascript function. As you can see it is pretty straight forward.

In one of my webpage, I have a parent window where i have a datalist with 10 rows of images. when i click any image a pop up window(child window) opens.
The child window has a form to be filled by user. Once user fills this form, he will press the save button. Once the save button is clicked, the child window should be closed and the datalist(in the update panel) in the parent window should be refreshed.
This is how I am trying to achieve this. On click of the save button a javascript function is being called of the parent window like this: window.opener.refreshDataList();
in the refreshDataList() function I have written the following code:
{
childWindow.close();
__doPostBack('ctl00_ContentPlaceHolder1_UpdatePanel1', '');
}
This works like a charm in Internet Explorer. However in Mozilla and Chrome it doesnt work. While testing this I added an alert statement ind the refreshDataList() function like this..
{
childWindow.close();
alert("Testing");
__doPostBack('ctl00_ContentPlaceHolder1_UpdatePanel1', '');
}
Once I added the alert statement, It started working in both mozilla and chrome.
So I realize that It could be an issue related to focus. I have done window.focus()
but still its not recieving any focus and not working in Mozilla and Chrome.
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 have a simple question - I use update panel with custom server control inside. I call __doPostBack from javascript and RaisePostBackEvent on the server fires (I implement IPostBackEventHandler).This is client to server call. Could I return data back to the client (after this partial postback)? What is the best way to achieve this?
View 2 RepliesI have a gridview within update panel, in gridview i have footer button to add new row in grid.

View 3 RepliesI have a small form with some static elements that I am able to access with javascript the bring up a popup. 4 textboxes are generated and attached to a updatepanel. I've been trying various methods of validating the contols without generating postback.
I found anytime i registered a javascript to the scriptmanager the page must refresh.
Is there anyway it can be done?
[URL] .... am using this functionality in my project and it is working very fine but i am facing very strange issue while using this.
The above functionality is not working when we place dropdownlist and textbox inside updatePanel and ModalPopupExtender
The .aspx page where i am using ModalpopupExtender and UpdatePanel for DropDownList and Textbox is below
<%-- *************************** MODAL POPUP EXTENDER ***************************************************** --%>
<asp:HiddenField ID="HiddenField3" runat="server" />
<asp:HiddenField ID="HiddenField4" runat="server" />
<cc1:ModalPopupExtender ID="ModalPopupExtender1" runat="server" PopupControlID="Div6" TargetControlID="HiddenField3"
BackgroundCssClass="modalBackground" CancelControlID="bclosemodalpopup" >
</cc1:ModalPopupExtender>
[Code] ....
The above code is not working with UpdatePanel but it is working if we remove DropdownList and Textbox from updatepanel.
The javascript code which i am using is below
<script type = "text/javascript">
var ddlText, ddlValue, ddl, lblMesg;
function CacheItems() {
ddlText = new Array();
[Code] .....
Some time ago (like 3 or 4 years) I heard about ability to generate JavaScript (client) code based on C#.NET source code. I don't remember details, probably that was for validation purposes only.

When an asynchronous postback happened inside update panel, another postback happens also for MasterPagenot only update panel embedded page .I want to prevent this MasterPage postback . is this possible ?think like i have a MasterPage and another page which is test.aspx which is content page of MasterPagei have update panel at test.aspxwhen asynchronous postback happens at this test.aspx update panel it also loads
MasterPage Page_Loadi want to prevent this (it should not also load MasterPage Page_Load)
I have a page with a control like this:
<asp:Button ID="test" runat="server" Text="test" OnClientClick="pageTracker._trackPageview('/bezichtigingsform/deeplink')" />
The OnClientClick-attribute is rendered as:
onclick="pageTracker._trackPageview('/bezichtigingsform/deeplink')"
When I try to escape the single-quote like this "'" or with a double backslash preceeding the single quote, this does not work. I also tried it like this:
string str = "pageTracker._trackPageview('/bezichtigingsform/deeplink'";
test.Attributes.Add("onclick", str.Replace("'", "\'"));
and of-course I tried all possible escaping-combinations in the above too.
It seems like asp.net just encodes the value, but how can I stop this? I want to be able to generate neat html/javascript-code...
problem, i've been 3 days more to solve this by myself but i got nothing.. really tired here.
Here's the situation :
1. I want to create a table (gridview) dynamically (programatically)
2. After i created that gridview, i have plan to put it into PlaceHolder.
And here's the problem :
- Whenever i create that table based on OnLoad Event the result is good, data is bounded normally, and from the HTML script i can see the table's script from <table> until </table>
But the main thing :
- If i generate that table not using the OnLoad Event, say, using Event from Click Button : the result is, this gridview printed normally, and the data also bounded normally, but i cannot see this table script using HTML... so far what i could see is <div> (as this is a placeholder).
Did i do something wrong here ? i really need this HTML script for generating other code based on this table, some other action i want to generate are saving data as per row, and authenticate it using javascript.
I have a page located in an iframe of another page. It calls a js function like this:
function F(a)
{
parent.document.getElementById('A').value = a;[code]....
It results in page reloading. How can I prevent it? Previously I've used return false; and it worked. But not in this case.
I have custom control with ASP.Net validators.
writer.AddAttribute(HtmlTextWriterAttribute.Onclick, "javascript:return DoSmth();");
function DoSmth() {
var cBox = confirm("Are you sure?");
if (!cBox) {
return false;
}
else {
//Invoke validation
}
When I push button submit, I call confirm box. If I press cancel - all right. But if I press ok, I need to do validation. How can I stop postback and do valiadation?
I couldn't find something similar in SO.
In ASP.NET, is there any way that on cue I can cause a partial postback with Javascript in an UpdatePanel?
I tried __doPostBack() but it does a full postback. I can trick it with a dummy button and fire click() then handle the partial postback that way, but I want a more graceful way than trickery.
