Need a recommendation for ASPX code – a message to the user.
Dear experts
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
txtMail.Focus();
return;
}
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.RegisterStar
It is provided from this library:
<%@ Register assembly="AjaxControlToolk
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.

You can accomplish this without the AJAX Extensions by using a Literal on your page that you can put script into:
<Literal runat="server" EnableViewState="false" id="javaScriptPlaceHolder"
In code you would then set the text of the Literal to be your script:
javaScriptPlaceHolder.Text
To control when you show the script you can either move it on the page or put it within a function that you call from the onload event of the body.
<Literal runat="server" EnableViewState="false" id="javaScriptPlaceHolder"
In code you would then set the text of the Literal to be your script:
javaScriptPlaceHolder.Text
To control when you show the script you can either move it on the page or put it within a function that you call from the onload event of the body.
It doesn't seem very practical to show an alert to a user from C# code at all since that is running on the server and this is disconnected from the client. How many websites do you see that actually show alerts? Wouldn't it be better to display a message to the user in the page in which case you wouldn't need to dynamically generate JavaScript at all.
If you still want a C# only solution, you could create a Literal control in code and add it to the pages control collection and it will be at the end of your page. Note that you will want to make sure that you set EnableViewState to false or set the Text before adding the control to the pages controls collection to avoid having extra data being stored in ViewState.
As far as your current method being deprecated an needing to work in all web browsers for five years, consider what is deprecated and what is running on the server. The method to register the client side script is a server side method so it relies on the .NET assemblies that you put on the web server and those will continue to work as long as you don't upgrade the assemblies used by your application on the server. As far as what is running in the client (web browser), it is the script that you dynamically generate plus some other script to call your script at the appropriate time.
I would recommend taking time to learn the platform that you are on and understand what you are doing.
