I want to alert some message on the click of a Button which is inside the Update Panel. Therefore I used "scriptmanager.registerstartupscript" but after using this I found that my event started responding slowly. Can anyone please help me in finding an alternative of "scriptmanager.registerstartupscript".The point that needs to be noted is that the button is in an Update Panel. And its my cenessity to find some alternative of it.
View 3 RepliesI am using a masterpage that contains a javascript script (does not matter what it does) and on each page under that masterpage I am registering that script to run on page load. On the page under the masterpage, I am calling a modalpopupextender to display on a button click. Now, if I disable the register startupscript, the popup extender works fine, if I register the startup up script it does not
here is the script regster call
ScriptManager.RegisterStartupScript(Me, Me.GetType(), "addscript", "miscscript()", True)
I have also tried this
Page.ClientScript.RegisterStartupScript(Me.GetType(), "addScript", "miscscript()", True)
I had this working fine using the second example when using .net 4 and the Ajax toolkit for 4 but I am now having to rollback to 3.5 due to a vendor requirement.
Here is a little bit of extra info:
If I put the script in page and not in the masterpage and just run with a window.onload, both work fine, which is why I have figured that it must be something that I am doing with the registration of the script.
When I say it does not matter what I put as the sript, I mean, it can be a complex element property adjustment or a simple alert, nothing seems to work.
I have this script in the masterpage because the script is used on everypage of the website.
I am also using the modalpopextender.show() on button click instead of using the element that it is attached to being the launching element.
I'm trying to do the next steps:1 - Click in submit Button inside update panel to make some server work - Ok
2 - If the work is succefully made i need to ask the user to confirm some information - I'm using a javascript function - Ok3- Javascript function executes and clicks in another button (hidden) inside the same update panel. - Ok4- Button click event fires and some server work is done. - Ok.5 - The panel doesn´t update - Wrong

I am working with vs 2008 and C#. I am having a code behind function as follows(not complete)
protected void btnShowZone_Click(object sender, EventArgs e)
{
string setofalllatsandlongs = null;
foreach (string s in ar)
{
[Code].....
</div>In thIn the click event of the btnShowZone(in bold) i am calling the code behind method and from that i am trying to call the js function using the script manager class.
But the javascript method is not getting called.the control is not going to the js function.
I have a user control that needs a javascript function so I put my JS code in a variable and used the ScriptManager.RegisterStartupScript in Page_PreRender of the control as follows
StringBuilder jscode = new StringBuilder();
jscode.Append(@"<script language=javascript>");
jscode.AppendLine(@"function MyFunc(x) { {alert('hi'); }");
jscode.AppendLine(@"</script>");

im using a init function after partial postback again the init function is not calling.
<asp:ScriptManager runat="server" ID="MainSM" EnablePartialRendering="true">
<Scripts>
<asp:ScriptReference Path="~/JS/menu.js" />
</Scripts>
</asp:ScriptManager>
<script type="text/javascript">
menu.init("class");
</script>
this script works fine but after partial postback again this init function is not working. So i searched in google i found some articles regarding this [URL]
<script type="text/javascript">
function pageLoad() {
// Initialization code here, meant to run once.
</script>
this works fine when it was postback,but without postback this init function is not working
This is what i am trying to do with asp.net updatepanel.i have button and a panel inside my updatepanel. when the button inside the updatepanel gets clicked i want to dynamically add new controls such as LinkButtons to my panel1 without full post back. Now when the dynamically added controls gets clicked it causes a full post pack and also not calling "LinkButton1_Click" event. i am sure i am doing something wrong here.

I am using a third party UI Library (devexpress) to implement some data grids. These grids work with Callbacks (not UpdatePanel partial Postbacks).
I am trying to use Scriptmanager RegisterStartupScript to execute some code on the client after the callback. This works great with partial postbacks but does not work with Callbacks.
Is there any way to queue client side code for execution inside the callback server side handler?
I'm not sure what triggers this to all of a studden stop working, but I'm sure where to start debugging or how to fix.I have this code below in my page...Everything on my site runs on a single page, and just about everything is an AsyncPostback after the first get. I'm not sure how it breaks after a while of clicking around, but when it break's, it breaks for good and will not run any startup scripts afterwards.stringa
public void MyRegisterStartupScript(string script, string scriptName)
{

I have one button and one textbox inside a updatepanel. On button click I am adding an alert script. But when I use the ViewSource by right clicking on the page, then the alert script is not generated.
[Code]....

But if I remove the the UpdatePanel then the script is generated and the alert message is displayed. What should I do to register the script when using updatepanel.
I searched google and found asynchronise post back trigger is used if we want update panel to post back on some event of control if it is out side the update panel. Than what is purpose of post back trigger ?

View 5 RepliesBeing new to ASP.NET I have run into trouble building my own Whack-a-mole program. I think my problem comes from using Buttons, which by themselves send post backs to the server, making the software unusable. The looks are in place, making new buttons show up in the grid, in different places by random. However, when a button is pushed - the score doesn't change (which I feel is strange).
Not so strange is that the Button doesn't work since it sends post back to the server - reloading the UpdatePanel. I think I should use a different controller like the CheckBox and style it hard using CSS (which isn't a problem). Is this the correct way to go, or should I make use of JavaScript AJAX instead?
Note to self: This technique shouldn't be used in a public application since it put too much unwanted pressure on the web server.

my code as below:
1) I have set EnableViewState = True
<%@ Page Language="VB" MasterPageFile="~/en/en.master" AutoEventWireup="false" CodeFile="product_detail.aspx.vb" Inherits="en_product_detail" EnableViewState="true" %>
2) I have set AutoPostBack & EnableViewState = True
<asp:DropDownList ID="ddl_order" runat="server" AutoPostBack="true" EnableViewState="true">
</asp:DropDownList>
I have a page where in there are various entry fields like name, registration number, country, state etc whcih are mandatory. On selection of country in dropdown,the state dropdown is filled and in the phone number boxes the country code is also filled simultaneously.
When I click on Save button it shows the required fields respective messages in the validation summary. When I select the country the state and country code are filled and the validation summary vanishes though I have not entered text in the other mandatory fields. None of the required fields messages are displayed though all fields except Country state and country code are filled.
I'm finding that the scriptmanager and the updatepanel and basic implementations of AJAX for ASP.NET. I'm just wondering whether these were required to use AJAX and partial page update and referencing handlers such as button1_click on the server code page ?
Also if i can ask another question, I'm also wanting to know whether the updatepanel can support feed-in like facebook ? What I'm wanting to do is have something that updates the screen (like the update panel), and items within this panel contains links. When the user clicks on the link it shows a modal div, giving the user options to do some updates. Once the user clicks submit, then this makes a call to the server to update the details then also update the panel. Within the panel I also want to move some of the div elements using javascript (causing the drag and drops to save to the database).

I have two Repeater controls, each hosted in a user control. Both user controls are contained in the same aspx page. Only one User Control is visible at any one time. The repeaters are comprised of checkboxes, and text boxes for user input.
The aspx page is configured with an Ajax ScriptManager; and contains several Ajax UpdatePanels. These UpdatePanels result in partial page post backs when text is changed in a textbox control in controls on the aspx page (this is not the behaviour for the Repeaters in the User Controls). Through use of several AsyncPostBackTriggers, various controls contained in the other UpdatePanels on the page have their content refreshed in response to the partial page post backs they are configured be notified about.
Depending on a radio button group selection, I set the visible property to true or false - as appropriate for the User control containing a repeater control. The Repeater control is then populated with data using databinding. All of this works.
However, when the Submit button is clicked, the Repeater control contains no data.
Given that I am not dynamically adding the Controls containing the Repeater controls (but using Visible true / false). I would have thought that the State of the fields and the data in the visible control would be preserved during the post back.
The User Controls are contained within the UpdatePanel that contains the Submit Button.
I have explicitly Enabled View state without any effect.
Am I correct in assuming that I should not have to do any explicit handling of data changes the user makes (via client side script and manipulation of an Data Structure Representing the Repeater Data); and the View State should maintain the data I need to access on the server when submitted?
I do not believe that it is the User Control visible state changes that are causing the issue because when the page is initially loaded on of the User controls is populated with dummy rows (so it displays).
I am suspicious that because the visible state of the controls is changed during partial page post back, that the Page View State ends up with no knowledge of the User Control and therefore cannot track its data (or changes).
I add cascading drop down in a place holder during page load. When i submit the entire form, i found out that my drop down list is reload and my selected value is not selected.
View 3 RepliesI have a css file which is external registered in Master Page which contents the following code :
.Item:hover
{
background-color: #def2fd;
font-weight: bold;
cursor:pointer;
}
The Item is applied for GridViewRow. This GridView is in a UpdatePanel, when I click a button to do a Ajax Post Back the CSS applied for the GridViewRow is useless (IE 6 only).
Is it possible to manually fire a AJAX postback from Javascript.
View 4 RepliesWe are having a button in an user control where this button is surrounded by update panel.
We are using above user control twice in a single page, then we will get 2 buttons in that page.
If we click on any of the button then page gets post back twice. Can some one let me know why it is happening and how to fix this?
