In Visual Studio 2008, you can not set a break point within a usercontrol / .ascx. But you can still debug your JavaScript code.

Make sure you uncheck Disable Script Debugging in Internet Explorer. Add the word debugger within your JavaScript code. Run the page and it will hit debugger line and prompt you with either the Built-In Debugger or you can use Visual Studio IDE. Now you can step through your code.

[codesyntax lang="java"]
function ValidateClientSizeComment() {
debugger
var clientSizeComment = document.getElementById(“<%= txtClientSizeComment.ClientID %>”).value.length;
if (clientSizeComment >= 50) {
var myVal = document.getElementById(‘<%= cvClientSizeComment.ClientID %>’);
ValidatorEnable(myVal, false);
}
}

You create a very cool ASP.Net Web Service on your local machine. You are ready to show the world, you deploy it on the server. Then you get the following message "The test form is only available for requests from the local machine. " Here is what you need to fix that.

Open the web config file and add the following, you will be able to access the form outside of the localhost:

<configuration>
    <system.web>
    <webServices>
        <protocols>
            <add name="HttpGet"/>
            <add name="HttpPost"/>
        </protocols>
    </webServices>
    </system.web>
</configuration>
