Call Javascript Function From Code Behind After Server Side Code Executes
May 25, 2010
I have an asp.net button, that when clicked calls a code behind function. The function does some evaluation, and then I want to call javascript from within this asp.net function.
<asp:LinkButton CssClass="button" ID="btnApply" runat="server" OnClick="btnApply_Click()" OnClientClick="Apply1('btnApply')" > hi ihave this functin in .vb file Protected Sub btnApply_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnApply.Click end sub
How can call som code behind in javascript? (asp.net 3.5) For example: we have javascript function to get textbox length,and we want to update gridview(Gridview1.databind()) when textbox.length=3
I want to pass some argument to javascript function from code behind. My Javascript function as follow. how to send arg to this func. from server side code.
function addTab(tabid,tablist) { //to Find the Panel var Panel = $find("<%=RadPanelBar2.ClientID %>"); //To find the Tab Strip var tabStrip = Panel._findItemByValue("QueueGridPanel").findControl("RadTabStrip2") tabStrip.get_tabs().clear(); var newTabNames = "MyTab1,MyTab2,MyTab3"; //var newTabNames = document.getElementById("ctl00_GridContentPlaceHolder_hfTabs").value; var TabsNames = newTabNames.split(','); var i = 0; while (i < TabsNames.length) { var ntab = new Telerik.Web.UI.RadTab(); tabStrip.get_tabs().add(ntab); ntab.set_text(TabsNames[i]); i++; } return false; }
My external javascript file named "messages.js" located in the "/scripts" directory:
[Code]....
How do I call this function from my codebehind? I need to register it through the client script manager right? Can someone provide me the call as I'm not sure how to add the function through an external file using type="text/javascript"
What I want to do: dispose of a session upon detecting an "OnBeforeUnload" event in the client. I know it doesn't fire 100% of times (90% accuracy works fine for me)
Here I saw how to do it with ajax, this system, however, breaks down with ajax: I can't use it at all.
how can i call javascript function from code behind from my Page.aspx.vb. in my Page i have a button i want to add this function to my button onclick="refreshParent();"
My motto is to call a Java script function at the end of button click code behind. ie, firstly i need to execute the server side function after which my java script function should get invoked. My server side method is as follows
protected string SaveEmbedURL_click() { if (txtembedurl.Text != null) { School aschool = new School(); aschool.SchoolId = CurrentSchool.SchoolId; aschool.EmbedUrl = txtembedurl.Text; SchoolRespository.updateEmbedUrl(aschool); return "true"; } } My Java script function is as follows function SaveEmbedUrlClientSide() { admin_CustomizeTheme.SaveEmbedURL_click(true); $('#lbl_embedcode').removeClass('hide').addClass('show'); $('#embedCode').removeClass('hide').addClass('show'); CopyToClipboard("embedCode"); }
I am building a user registration form in asp.net. I want to check if the username is available or not on the leave event of the TextBox. I am not able to get the Leave Event of the TextBox.

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 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.
