Hi all,

How to call javascript function from code behind in .net 2.0 framework? I have tried following ways, but none of them are working.

C#

1. 
ClientScriptManager cs = Page.ClientScript;
if (!cs.IsStartupScriptRegistered(this.GetType(), "Alert"))
 cs.RegisterStartupScript(this.GetType(), "Alert", "alert('Please Enter valid data');", true);

2.

ClientScriptManager cs = Page.ClientScript;
cs.RegisterClientScriptBlock(this.GetType(), "MsgWindow", "alert('Please Enter valid data');", true);

3.

Response.Write("<script type='text/javascript'>alert('Please Enter valid data');</script>");

thanks
