string strMessage = "Processing Successful"; string strScript = "<script language=javascript>alert('" + strMessage + "');</script>"; ClientScript. RegisterStartupScript(Page.GetType(), "startup", strScript);

string strMessage = "Processing Successful"; string strScript = " alert('" + strMessage + "');"; ClientScript. RegisterStartupScript(Page.GetType(), "startup", strScript);
