Call ASP . NET function from JavaScript?

Call ASP . NET function from JavaScript? I'm writing a web page in ASP . NET. I have some JavaScript code, and I have a submit button with a click event. Is it possible to call a method I created in ASP with JavaScript's click event? You should be using some Ajax library like : Anthem 20 Answers Well, if you don't want to do it using Ajax or any other way and just want a normal ASP . NET postback to happen, here is how you do it (without using any other libraries): It is a little tricky though... :) i. In your code file (assuming you are using C# and .NET 2.0 or later) add the following Interface to your Page class to make it look like public partial class Default : System.Web.UI.Page, IPostBackEventHandler{} ii. This should add (using Tab-Tab) this function to your code file: public void RaisePostBackEvent(string eventArgument) { } iii.

Triple Quotes? How do I delimit a databound Javascript string parameter in ASP . NET? How do I delimit a Javascript data-bound string parameter in an anchor OnClick event?

Since I can't use 'single quotes' again, how do I ensure the Javascript function knows the input parameter is a string and not an integer? Without the extra quotes around the input string parameter, the Javascript function thinks I'm passing in an integer. The anchor: <a id="aSho

ASP_Net Custom Client-Side Validation

ASP . NET Custom Client-Side Validation I have a custom validation function in JavaScript in a user control on a .Net 2.0 web site which checks to see that the fee paid is not in excess of the fee amount due. I've placed the validator code in the ascx file, and I have also tried using Page.ClientScript.RegisterClientScriptBlock() and in both cases the validation fires, but cannot find the JavaScript function. The output in Firefox's error console is "feeAmountCheck is not defined" . Here is the function (this was taken directly from firefox->view source) <script type="text/javascript"> function feeAmountCheck(source, arguments) { var amountDue = document.getElementById('ctl00_footerContentHolder_Fees1_FeeDue'); var amountPaid = document.getElementById('ctl00_footerContentHolder_Fees1_FeePaid'); if (amountDue.value > 0 && amountDue >= amountPaid) { arguments.Is
