I have an application that needs to display a confirm dialog box. I want to use Javascript to display in .cs file. The dialog box should be fired automatically i.e. it should not be fired by onclick or onclientclick etc.....
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
if ( temp == true ) // checking some condition in application

I just want to make sure that I got this right. If I have two update panels, and updatepanel1 has 10 dynamic controls created from an external button that resides on the page by default.. and then i have a second button which also is on the page by default but is an asynctrigger to updatepanel2...
then when the first updatepanel1 is populated with dynamic controls, then when I click button2 to update the second updatepanel2 with some data, the dynamic controls in updatepanel1 wil;l still remain there right? but does it persist by itself on postback? And if so why?
because when I click button2 to update updatepanel2, it does a partial page postback. So when it does a partial page postback, does that mean it does not destroy updatepanel1's dynamic controls?

I have a JavaScript-based timeline which needs to use data from an SQL server. The queries and the JSON conversions have been worked out in the form of C#.NET functions within a code file related to an .aspx page. So for a complete newbie to ASP.NET, how do you set up a function call like this from JavaScript?I would love it if someone had some simple example code I could learn/get some pointers from.Edit: I am using .NET 3.5

View 2 RepliesI'm working on a C# web app and I've to handle some javascript code.
I can do it both using javascript injection from my .cs file, which I'm doing now or choose to include my code into an external js file.
I would like to know when you would prefer to choose one way over the other.
According to me, it can be more clear to put code in external .js file and it can ease debugging.
Code injection from code-behind would however keep together all the necessary code for my component.

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.

View 2 RepliesA 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):

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...]
So I have this idea of creating a asp.net user control, to handle all forms of modal popups (whether it be error handling, forms, dialogs, etc).
I already created this before, placing the user control in the top master page, exposing it to all content pages, so I could do something like:
Master.Popup.ShowException(Exception);
And the usercontrol itself would have the necessary markup to look like a modal dialog, and in the show method just do a .Visible = true.
This is all fine, but I've started thinking of implementing a bit of style with jquery. I'd like for the usercontrol to have some sort of jquery animation on show. But I don't know how to go about achieving this, as I don't know how I would call that jquery function from the codebehind instead of the popup.visible = true.
I have a modalpopupextender that I want to run based on a timer control. I've tried using the clientregisterscript to run some javascript code to perform a fake click on the link control that initiates the modalpopup, but with no luck. What is the best way to either show the modal dialog programatically or register a jscript that will do this.
View 2 RepliesHow can i use same javascript code for age calculation from two different Ajax CalemdarExtenar?
View 1 RepliesI 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 ?
So in my website, I use jquery to fetch data through ajax. AS part of the ajax response, some of the javascript code comes as well which is executed. The problem is how to debug this javascript in firebug or other tools. This is my experience so far: putting debugger; doesn't work For some javascript, can't set the breakpoint as that script is not yet loaded. even if this new javascript calls some other function thats already loaded (i.e. i can see it in firebug and set a breakpoint), that breakpoint on that function is still not triggered
However, the javascript does executes normally and even things like console.log works but cant seem to debug it.
button click i get the result from the sql server table and fill it to DataTable

I have a button that needs to check if a contact exists.I have used the Jquery ajax function to do this and I do successfully gind out if the contact exists or not.However I cannot find a way for the javascript code to wait until the ajax has finished so I can return true/false to the button for it to continue server side function.

I have a popup window (aspx page) which is used to save log messages to the DB. I want to close this popup as soon as the user clicks the save button and the message has been saved into the database.
