I have a web application that will need to access code behind methods as well as javascript methods. For this particular implementation it doesn't really matter which order they are called in from a program flow perspective.
I'm looking for insight into when it would be appropriate to use a code behind to call javascript and when it would be appropriate to call javascript from a code behind. Are there any ramifications of doing it one way or the other that I should be aware of before moving forward with an implementation?
Is there a best practice way to do it or is it very specific to the actual implementation?
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 1 RepliesSo 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 java script function which presents a countdown timer.when the timer reaches zero, I want to somehow activate a function on the server side in the code-behind.I understand it is impossible to directly call a server-side function, but is there a simple way to still fire it?I want to fire the (event-handler) code behind function: protected void ButtonFinish_Click(object sender, EventArgs e).
var _countDowncontainer = 0;
var _currentSeconds = 0;
function ActivateCountDown(strContainerID, initialValue) { _countDowncontainer = document.getElementById(strContainerID);

I am using Ajax's EnablePageMethods way to call server side code using javascript. The problem is that in IE8 the page automatically refreshes after the ajax call has been completed i.e. the server side function has been executed successfully. I want the same to happen with Chrome and Firefox but it doesnt refresh the page once the server side function has been executed.
I am using this way to call server side code from Javascript -- [URL]
this is the javascript function:

I am trying to call a JavaScript function from my ascx control code behind in the catch blockI have tried the below two ways but they don't seem to work.
Page.ClientScript.RegisterClientScriptBlock(typeof(string), "script", "test();", true);
ScriptManager.RegisterStartupScript(Page, GetType(), "err_msg", "alert('error');", true);
I often want to call a function in the code behind using the "<%# ... %>" syntax. Sometimes is works and sometimes it doesn't. It is also a difficult syntax to search for. Can someone point me at an explanation of the working (or not) of this syntax?
I just tried this:
<asp:TextBox
ID="TextBox1"
runat="server"
Text="<%# getBCSConnectionString() %>"
></asp:TextBox>
For example. The function is in the code behind (it returns a string). The TextBox is empty and no break point is hit in the function; it does not appear to be called.
I want to call a validate function on asp:button click event and also want to do some server side work on this click like adding values to session variables and redirecting page to new one.

View 1 RepliesI have a web form in which I create many controls including a submit button dinamically.
I want to check a condition in the button's click event and if it comes true, call a javascript funtion to show an alert. but the problem is when I use :
Page.RegisterClientScriptBlock("ClientScript", script);
in the btn_Click event, it is not working. I guess the script should be registered at page_load.
