Simple,

Add the following class in your solution/project,

///
/// A JavaScript alert
///
public static class Alert
{
///
/// Shows a client-side JavaScript alert in the browser.
///
/// The message to appear in the alert.
public static void Show(string message)
{
// Cleans the message to allow single quotation marks
string cleanMessage = message.Replace("'", "\\'");
string script = string.Format("", cleanMessage);

// Gets the executing web page
Page page = HttpContext.Current.CurrentHandler as Page;
// Checks if the handler is a Page and that the script isn't allready on the Page
if (page != null && !page.ClientScript.IsClientScriptBlockRegistered("alert"))
{
page.ClientScript.RegisterClientScriptBlock(typeof(Alert), "alert", script);
}
}
}

Just use Alert.Show("Your message"); where ever you want to show the message.

1. Add scriptmanager ,update pannel and button
2.Add post back event to button

Postback event
protected void btnrefresh_Click(object sender, EventArgs e)
{
//do the validation here
string CloseWindow; CloseWindow = "alert('Hello World')";
ScriptManager.RegisterStartupScript(this, this.GetType(), "CloseWindow", CloseWindow, true);
}

ClientScript.RegisterClientScriptBlock(this.GetType(), "validation", "alert(username and password is incorrect ');", true);
