How to hide a particular list item of radiobuttonlist

My friend working in asp.net he has used gridview in aspx page. In this case he want to hide the particular radiobutton from the radiobuttonlist.

So I helped him to fix.

<asp:GridView ID="CrowdRatingGrid" runat="server" AutoGenerateColumns="false" AllowPaging="true" PageSize="4" OnPageIndexChanging="CrowdRatingGrid_PageIndexChanging" ViewStateMode="Enabled">

<PagerSettings Mode="Numeric" PageButtonCount="4" />
<Columns>
<asp:TemplateField>
   <HeaderTemplate>
    Rating
    </HeaderTemplate>
    <ItemTemplate>
     <asp:RadioButtonList runat="server" ID="Rating" SelectedValue='<%# Bind("rating_id") %>'
                            RepeatDirection="Horizontal">
                            <asp:ListItem Value="0" />
                            <asp:ListItem Value="1" />
                            <asp:ListItem Value="2" />
                            <asp:ListItem Value="3" />
                            <asp:ListItem Value="4" />
                            <asp:ListItem Value="5" />
                        </asp:RadioButtonList>
                    </ItemTemplate>
                </asp:TemplateField>
         </Columns>
        </asp:GridView>

I found the solution to remove the RadioButton particular List from the RadioButtonList using the following the steps

Rating.Items[0].Enabled = false;

Editing based on comment by OP. To completely get rid of it you'll need to do this:

Rating.Items.RemoveAt(0);

and then when you want it back you'll need to do this:

Rating.Items.Insert(0, "0");

How to split the integer value from string

I am working asp.net develpment. I want to split the integer value from string value. so simply i found the solution using regular expression and split function

using System;
using System.Text.RegularExpressions;

class Program
{
    static void Main()
    {
 //
 // String containing numbers.
 //
 string sentence = "10 cats, 20 dogs, 40 fish and 1 programmer.";
 //
 // Get all digit sequence as strings.
 //
 string[] digits = Regex.Split(sentence, @"\D+");
 //
 // Now we have each number string.
 //
 foreach (string value in digits)
 {
     //
     // Parse the value to get the number.
     //
     int number;
     if (int.TryParse(value, out number))
     {
  Console.WriteLine(value);
     }
 }
    }
}

How to Implement Logout Functionality and BackButton Event functionality in Phonegap

I am working in phonegap mobile application I want to implement logout functionality in my mobile application.

$('#logoutButton').off("click").on("click", function () {
        $("#pass").val("");
        window.localStorage.clear(); 
        
      $.mobile.changePage("#login",null,true,true);        
    
    });

In case you want backbutton to exit an app in one page and in other to act as a real back button you should use this:

document.addEventListener("backbutton", onBackKeyDown, false);

function onBackKeyDown() {
    if($.mobile.activePage.is('#loginpage')){
                 navigator.app.exitApp(); // Exit app if current page is a login page
    }
    else {
        navigator.app.backHistory(); // Go back in history in any other case
    }
}

To remove/prevent a backbutton event use this:

document.addEventListener("backbutton", function(e){
    e.preventDefault();
}, false);
