Need a recommendation for ASPX code – a message to the user.
Posted on 2013-01-05
I’m a professional programmer with 10+ years in business, but new to ASPX coding and need little help. When my user click on Submit button I do some check with such kind of code:
if (byteState == 2)
Page.RegisterStartupScript("codice", "<script>alert('User with such email already extist! Probably this mean that this user is already register and do not need new registration!');</" + "script>");
It works, but I get warning that this metod is decprated. Could you recommended me what code I should use? Also, please give me example how I’m possible to show new line in the message.
Other metod I use for message to the customer is with this code:
CustomMessage = "alert('Unexpected error in spUsers save record to local DB');";
ScriptManager.RegisterStartupScript(this, this.GetType(), "CustomMessage", CustomMessage, true);
It is provided from this library:
<%@ Register assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" tagprefix="asp" %>
Is this a good option? It look to me that it require to load a whole script library between 10 and 15 kb. In size, is that true???
My primary dermands is
1) To use a standart commands, which will be supported in next 5 years from all WEB brousers.
2) To save internet traffic.
