Confirmation Message Box using Javascript in between code from Code behind

Hi all,

Im using C# as my code behind, im having a code in the button click event where im checking whether a file is exists, if it exists then it show the confirmation message box like "file found, want to continue", but its happening if we register the script in the page load  and its not checking the condition. By clciking the button itself its showing the message box.


i need that script should get pop up only after the condition get satisfied. Is it possible? Please help me out to solve this problem. Thanks a lot in advance.

The code is given below


void Page_Load(object sender, System.EventArgs e)


i = "file Exists";

StringBuilder str =

new StringBuilder();

str.Append("<script language=javascript>");

str.Append("function PopWindow()");


str.Append("alert('hello world')");









private void Button1_Click(object sender, System.EventArgs e)


if (i=="file Exists")


int x= 0;

int y =0;

x = x+ y;


int a = 2;

int z = 2;

z = z+ a;

How to code confirm message box after code-behind logic
Hello, all  In a GridView, when the user, after making changes in a row, clicks the Update button, I need to query a database table to determine if I need to display a message box. Basically, I need to inform the user that they are about to change other records as a result of the change they want to make in the currently edited row. And give the user the opportunity to cancel the update. A simple client side return/confirm button won't work, as depending on the particular changes the user makes in the record, the change may or may not cause an update ...

Using App_Code shared code in page code-behind AND code-front
Hi all, I've only just come across what seems to be the 'correct' way of making use of shared code in my .Net sites: I code some classes in a .cs (in my case - i'm using c#) file. I then put them inside namespaces. To make use of the classes in the code-behind of my web pages, I simply add a "using MyNamespace;" line at the top, and then I can make use of a class' contents like so: "MyClass1.MyString1(SomeVariablesToSend)". Now that works fine when working in the codebehind, but what happens when I want to call the class/string from my code-fron...

what about the code-behind (code behind)
One MAJOR difference between AJAX.NET and Atlas.NET seems to be that AJAX.NET is able to expose methods in your codebehind to the client. Why doesn't Atlas do this? Or am I mistaken? With AJAX.NET it's just a simple line or two:  Ajax.Utility.RegisterTypeForAjax(GetType(myClass)) <Ajax.AjaxMethod()>Public Function myFunction PLEASE tell me Atlas has something comparable to this. I don't have the time to rewrite all my code-behind methods in javascript or atlas script. All you need to do in Atlas to expose a method on your page (or its code behind class) is to put a [WebMet...

Is there any difference between using VB.NET or C#.NET except for the code synthax. Thank you and come again. A lot of samples show inline code just for simplicity.. i personally use code-behind because I like to seperate my code from presentation. As for VB.NET or C#, its your preference.. there is no difference really when its all said and done. From a purely mathematical sense, having everything in a single file would s...
