ASP.NET C# Calling a javascript function from asp

[chathura86]

i am creating a ajax enabled page

i have a update panel and inside that i have a button

what i want to do is when the button clicked it will do some
process and after that i want to show the result in a message box

i want to know how to call the javascript alert() function;

for a example

client code:

<asp:UpdatePanel ID="updatePnl" runat="server">
      ....................
      .....................
        <asp:Button ID="Button1" Text="Login" OnClick="Button1_Click" runat="server" />
      .......................
      ........................
</asp:UpdatePanel>
 

server code

    protected void Button1_Click(object sender, EventArgs e)
    {
         //some process
         //after that call javascript alert('msg'); 
    }
 

hope this is clear

sorry but that didnt work

i got the following error

Sys.WebForms.PageRequestManagerParserErrorExceptio n: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled. Details: Error parsing near '


i trued this and it seems to be working but not sure

    ScriptManager.RegisterStartupScript(Page, this.GetType(), "MyMessageBox", "javascript:alert('hello')", true);
