In this post we will discuss how to call a JavaScript function from a code behind file in Asp.Net. Also you can check out my previous posts on:
- Increase column size in sql server 2008
- The underlying provider failed on Open error in Asp.Net Entity framework
- Sealed class and Sealed method in C#.Net
In this example, we will call a JavaScript method from a button click.
.Aspx Code:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default18.aspx.cs" Inherits="Default18" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Call JavaScript method from code behind file</title>
<script type="text/javascript">
function JavaScritFromCodeBehind() {
alert('Welcome to JavaScript Call from Code Behind file');
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Button ID="btnClick" runat="server" Text="Click to call JavaScript Function" OnClick="btnClick_Click" />
</div>
</form>
</body>
</html>
.cs Code:
protected void btnClick_Click(object sender, EventArgs e)
{
Page.ClientScript.RegisterStartupScript(this.GetType(),
"Welcome", "JavaScritFromCodeBehind();", true);
}
or if you are using AJAX, then you can try like this:
ScriptManager.RegisterStartupScript(this, this.GetType(), "CallMyFunction", "JavaScriptFunctioName();", true);
Now when you run the code and click on the button.
