# Problem in displaying  alert box in asp.net

how we show the [alert](https://answers.mindstick.com/qa/30927/what-is-an-alert) box in [code behind](https://www.mindstick.com/forum/2199/call-javascript-s-function-from-code-behind) of [asp.net](https://www.mindstick.com/articles/934/default-folders-available-inside-the-asp-dot-net-application-folder)\

we display the alert box in asp.net by using Registerscript function.\
**Example:**\
**Syntax:**\
Void ClientScriptManager.RegisterStartupScript(Type type,string key, string script)\
\
Example:\
Page.ClientScript.RegisterStartupScript(GetType(), @"startup", @"<script>alert('" + Hello + "');</script>");\
