Checked the checkbox if value of each checkbox match string in the c# array string using jquery

Question

I have asp.net mvc 3 application. I have build the EDIT View which consist of different checkbox with same name and different value. I want to checked the checkbox by matching value of checkbox with the value in array of the string of c#.

Action:

public ActionResult Edit(int id)
{
    string[] AllRole = roleassign.Role.Split(',');
    ViewBag.allrole = AllRole;
    ViewBag.role = ivr.get_all_role();
    return View();
}

AllRole is array String consist of "administrator","member","supervisor"

View

          @foreach (var list in ViewBag.role)
            {
            <input type="checkbox" name="role" [email protected] /> @list.Name
            }

How Can I loop through the ViewBag.allrole array string in jquery and checked the checked box which have value that is in the ViewBag.allrole array string. Edited In View It Creates Entire set of Checkbox of all avaiable Role as follows:

<input type="checkbox" value="Administrator" name="role">
Administrator
<input type="checkbox" value="Moderator" name="role">
Moderator
<input type="checkbox" value="voice" name="role">
voiceanchor
<input type="checkbox" value="member" name="role">
member

If the ViewBag.allrole consist of array of "administrator","moderator" then I want to checked the checkbox with those value in checkbox using jquery

Ok, let me put it another way, where is the code that creates the checkboxes for the entire set of roles? — Justin Harvey

If you are using .NET Membership, you can do something like:

@foreach (var role in Roles.GetAllRoles)
{
    bool checked = Roles.IsUserInRole(role);

    <input 
         type="checkbox"  
         name="role" 
         value="@role.Name" 
         @(checked ? "checked='checked'" : "")/> @role.Name
}

in your particular example, you can do almost the same

string[] userRoles = ViewBag.role;

@foreach (var list in ViewBag.allrole)
{
    bool checked = userRoles.Contains(role);

    <input 
         type="checkbox" 
         name="role" 
         value="@list.Name" 
         @(checked ? "checked='checked'" : "")/> @list.Name
}

please change your variables accordingly if I missed something, as they're not very intuitive.

The second one actually worked. I was so confused as two viewbags created a mess. saved me thanks!. .Contains() did a top notch work!!
