Using ASP.NET to validate a radiobutton list using JavaScript, followed by invoking a C# function

After experiencing some errors, I have refined my question to better articulate my objective. By revising the logic of my previous issue - where no text appeared in a pop-up dialog triggered by a C# script utilizing a JavaScript method - I present my updated inquiry:

My radio button group is set up as follows:

<asp:RadioButtonList ID="rblMyGroup" runat="server" 
     RepeatDirection="Horizontal">
     <asp:ListItem>Yes</asp:ListItem>
     <asp:ListItem Selected="True">No</asp:ListItem>
</asp:RadioButtonList>

In C#, how can I determine if "Yes" is selected? If it is, how do I prompt a pop-up message asking "Are you sure?" When the user selects yes, a specific method should be executed, while clicking cancel should result in no action. If "No" is chosen, the same method as for "Yes" should be triggered.

The C# method in question is named: myAwesomeMethod(string s). When this method is invoked, it will alter the text displayed on a button within the page. This simplification aims to enhance clarity and understanding of the problem at hand. Successfully resolving this issue will aid me in addressing other challenges I am currently facing.

Answer №1

Unsure if this is exactly what you're looking for, but the code needs to have instructions on what to do when the user clicks "Yes."

<script type="text/javascript>
    function validate() {
        var response = confirm('Are you sure?');

        if(response == true) {
           alert("You clicked OK!")
        } else {
           alert("You clicked Cancel!")
        }
    }
</script>
