i'm a beginner with c# 2.0 and ajax
i have two radio button and i want to execute a javascript if user selected the second radio button
i want execute a javascript if confirm(message)
but i wonder if it possible to GET the value of the if (confirm) if user has click ok or cancel !?
Basically i have two asp.net buttons on my asp.net page as follow:
[Code]....
and this is the code behand fo btnSave onclick event:
[Code]....
and this is the code behand of btnPreviwe onclick event:
[Code]....
as you can see, when the btnSave is clicked, it is programmatically clikced the btnPrevew first, and btnPreview registers and fires the required JavaScript. But actually once the btnSave clicked, it does go to the btnPreview_OnClick event, but for some unknow reasons, the javascript in btnPreview_OnClick doesnt work, however, when i just put cstext2.Append("alert('hi')" instead of cstext2.Append("'SaveSignature()'", the javascript does executed, and also if i modifed the asp.net code for btnPreview to this, it works too.

I have a drop down in an ASP.NET page. Whenever the value of the drop down changes an ASP.NET AJAX request is made to the server. I also attached a jQuery "change" event handler to that list to execute some code when the value is changed. So, probably two different event handlers are being attached to the same drop down, and it's causing some problems, i.e., sometimes wrong drop down values are sent to the server. I don't know why is this happening but I think attaching two different event handlers to a same drop down may be the reason.
Can anyone tell me what is the problem here? If what I guessed is true, then is there any other way to execute some custom javascript code before asp.net AJAX request is sent ?
I have a button on my aspx page. I want to use javascript confirm before continuing execution when clicking on that button. I can do it easily if i am writing javascript in aspx page itself . But my problem is each time the confirm message may be different. I need to check various condition to generate appropriate confirm message.Can I call confirm in my code behind, so that I can construct confirm message from there?What I'm trying is:
protected void Button1_Click(object sender, EventArgs e)
{
//just the algorithm given here

I'm trying to understand how to execute AJAX animation on an asp button that has to execute code on Postback. In other words, I have button with code behind that needs to be excuted, but at the same time want to be able to have one of animation extenders be applied to it. I understand that I need to use the BeginRequest Event, I'm just not sure how, or which javascript commands to use to call the ajax animation so the postback will still occur.
View 5 RepliesInside my boxLang_OnSelectedIndexChanged() event I got this :-
if (txtbox1.Text != "" && txtbox2.Text != "")
{
ScriptManager.RegisterStartupScript(Page, Page.GetType(), "confirm", "confirm('Changing the language will clear the text in the textboxes. Click OK to proceed.');", true);
txtbox1.Text = "";
txtbox2.Text = "";
}
Now what is happening is that. When I select a different item from the drop down list this confirm box does show up BUT it first clears the content of the text boxes and then this confirm box appears. What I want is that the textboxes content should be cleared ONLY when OK is clicked.
I am trying to get a new line when display the message. Whats wrong with this code?
Button l = (Button)e.Row.FindControl("btnDelete");
string textForMessage = @"<script language='javascript'> confirm('Are you sure you want to delete this record
test
test
test');</script>";
l.Attributes.Add("onclick", textForMessage + DataBinder.Eval(e.Row.DataItem, "Name") + ")");

View 6 RepliesI have downloaded a jquery tool which creates overlay windows so here is the code which I want to trigger by calling a javascript function instead of a button or link.

The HTML note the overlay is executing when i click the button i want this to be triggered on javascript function)

All i want to do is call a function lets say "ShowOverlay()" from my code behind using ClientRegisterScript() and it should do the same as it is doing on button.
how to execute the code behind function using JavaScript keypress ?
The reason is that the keypress that I'm referring to will be used in searching record so I want that every keypress a result will be shown in the gridview immediately.
Executing Server side code using Javascript. Here is the solution.In the Asp.net forums, I often see the question asked, "Can I call server-side code from the client/JavaScript?" Almost invariably, the responses given are "No, the client cannot access the server," or "You can only use WebMethods or PageMethods." The first response is not entirely correct, and unfortunately, WebMethods and PageMethods are static methods and therefore have no way to directly access the page.This is why I present to you the following "hack". I call it a hack because there really should be some way built into the ASP.NET AJAX Extensions that allow this approach directly. Instead, it relies on using controls in a manner that they aren't necessarily intended in order to obtain the desired result. But this "hack" does have a redeeming quality—it's incredibly easy.The Code:
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default2.aspx.vb" Inherits="Default2" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

I have an UpdatePanel with a repeater in it that is re-bound after a user adds an item to it via a modal popup. When they click the button to add a new row to the repeater the code-behind looks something like this:
protected void lbtnAddOption_Click(object sender, EventArgs e)
{
SelectedOption = new Option()
{
Account = txtAddOptionAccountNumber.Text,
Margin = chkAddOptionMargin.Checked,
Symbol = txtAddOptionSymbol.Text,
Usymbol = txtAddOptionUsymbol.Text,
};
Presenter.OnAddOption(); // Insert the new item
RefreshOptions(); // Pull down and re-bind all the items
mpeAddOptionDialog.Hide(); // Hide the modal
// ... Make call to jQuery scrollTo() method here?
}
This works fine and the new row will show up quickly via the UpdatePanel. However, there are often hundreds of rows and where the new one is added is based on the current sorting column used. So, I wanted to take this as a chance to use the sweet jQuery ScrollTo plugin. I know that if I give it the ID of my overflowed container div and the ID of an element within it, it will smoothly scroll straight to the users newly added row. However, there are two problems:
I need to find the appropriate row so I can snag the ClientID for it. I need to execute the jQuery snippet from my code-behind that will cause my newly updated repeater to scroll to the right row. I've solved #1. I have a reliable method that will produce the newly added row's ClientID. However, problem #2 is proving to be tricky. I know I can just call ScriptManager.RegisterStartupScript() form my code-behind and it will execute the JavaScript on my page.
The problem I'm having is that it seems that it is executing that piece of JavaScript before (I'm guessing) the newly refreshed DOM elements have fully loaded. So, even though I am passing in the appropriate jQuery line to scroll to the element I want, it is erroring out for me because it can't find that element yet. Here is the line I'm using at the end of the method I posted above:
string clientID = getClientIdOfNewRow();
ScriptManager.RegisterStartupScript(this, typeof(Page), "ScrollScript", String.Format("$("#optionContainer").scrollTo("{0}", 800);", clientID), true);
What do I need to do so I can ensure that this line of JavaScript isn't called until the page with the UpdatePanel is truly ready?
in my asp.net website, i have textbox control inside datagrid control. I would like to add textchange event in javascript where i need to sum the values inside textboxes in datagrid and show that addition in lable outside grid. I would also like to do same addition in codebehind(*.cs) But codebehind only execute when browser not support javascript. It means when browser support javascript only client side javascript should execute not server side code

Using ASP.NET 2.0, VB code behind, I am using a ModalPopupExtender to show some dynamic content on my site inside an update panel. The problem I am having is that sometimes the content stretches the modal pop-up panel (div) so that it flows off the screen. In cases where the height of the popup panel exceeds some defined height I would like to limit the height and add a vertical scroll bar (otherwise the panel should have no height minimum).
I have written a JavaScript to perform this task (see below). I use my code behind to display the modal popup... so now my problem is how (when) do I kick-off my javascript to limit the height of my modal popup. Kicking off the script on pageLoaded finds that the popup container's display setting has not been set yet, therefore ConstrainPanelHeight is never executed... how can I kick off my javascript after the model popup is shown?
[Code]....
i want to display time on my screen and therefore i used timer control inside update panel and set my timer interval to 1000 but the time displayed after 3 seconds i mean 56 -53-52-49..... how to solve this below is the code
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:Timer ID="Timer1" runat="server" Interval="1000" OnTick="Timer1_Tick">
</asp:Timer>
<asp:Label ID="Label2" runat="server" Font-Bold="True" Font-Names="Microsoft New Tai Lue" Font-Size="Large" ForeColor="royalBlue" Height="25px" Width="162px" ></asp:Label>
</ContentTemplate>
</asp:UpdatePanel>
I'm not sure if this is an easy issue to solve, but I can't seem to figure it out. I have a ModalPopupExtender (obviously) for a panel that contains a two labels, two textboxes, and two buttons (Ok and Cancel). What I would like to do is when the Ok button is clicked, the page post back and the server click event execute (along with normal page events). When I try adding "__doPostBack("ModalOk", "");" as the OnOkScript, the page posts back, but the click event doesn't execute. (the click event is Protected Sub ModalOk_Click(blah blah) Handles ModalOk.Click).
The only way I got it to work (which is fine with me, I just thought I'd ask why it isn't working normally) is by checking to see if the Request.Form("__EVENTTARGET") is equal to "ModalOk". If it is, then I call the ModalOk_Click() sub. Like I said, this is fine with me, but it should be able to be avoided. If the __EVENTTARGET is equal to "ModalOk", then the "Handles ModalOk.Click" event should automatically be called, shouldn't it? Following with the general problem here, how does the server determine which events (other than the page events) to execute (or at least which button.click event)? I understand that the __EVENTTARGET supplies what causes the postback, but if a button is clicked then __EVENTTARGET is not set. So then does the page check the Request.Form for a button? Or is it more complex/simple than what I'm asking?
I want execute below callback() method after completion of document.getElementById('btnDownload').click(); method . Now callback()executing immediatly. I want wait "Click()" process done then Execute callback(); method.
function LoadPopup() {
// find the popup behavior
this._popup = $find('mdlPopup');
// show the popup
this._popup.show();
// synchronously run the server side validation ...
document.getElementById('btnDownload').click();
callback();
}
function callback() {
this._popup = $find('mdlPopup');
// hide the popup
this._popup.hide();
alert("hi");
}
I want to prompt the user before allowing them to save a record. So let's assume I have the following button defined in the markup:
<asp:Button ID="btnSave" runat="server" OnClick="btnSave_Click"></asp:Button>
To force a prompt with normal javascript, I could wire the OnClick event for my save button to be something like this (I could do this in Page_Load):
btnSave.Attributes.Add("onclick",
"return confirm('are you sure you want to save?');");
The confirm call will block until the user actually presses on of the Yes/No buttons, which is the behavior I want. If the user presses 'Yes', then my btnSave_OnClick method would be called.
For the jquery dialog that is the equivalent, I tried something like this (see below). But the problem is that unlike javascript confirm(), it's going to get all the way through this function (displayYesNoAlert) and then proceed into my btnSave_OnClick method on the C# side. I need a way to make it "block", until the user presses the Yes or No button, and then return true or false so the btnSave_OnClick will be called or not called depending on the user's answer.
Currently, I just gave up and went with javascript's confirm, I just wondered if there was a way to do it.

I want a similar behavior of "confirm delete" option in ASP.Net Gridview, as this questions shows How to add a "confirm delete" option in ASP.Net Gridview ? but using Jquery Confirm Box.
I'm having a lot of problem with postback behavior and asp.net page flow.
I want domething simple as:
<asp:Button ID="ButtonRemove" runat="server" Text="<%$ Resources:Localizacao, BUTTON_REMOVE %>" OnClick="ButtonRemove_Click" OnClientClick="displayConfirmDialog();/>
how I can fire the OnClick event in javascript, or how a can put a Panel as confirm dialog?
*today I use ajaxcontroltoolkit, but as this was discontinued I'm trying to figure out some more elegant alternative.
i have a regular asp:button. I am working in .Net 3.5. I've tried adding a js confirm to the button with the OnClientClick attribute as well as adding in code-behind and the result is the same. No matter what the user clicks in the confirm pop-up the form will not submit?? BtnDeleteSelected.Attributes.Add("onclick", "return confirm('Are you sure you want to delete?');"); The confirm dialog appears and if i select "OK" it still does not submit..
