Question

Update1:

this is all looks great but there is big problem which i have been looking for and so far i havent found that yet. – see my comments in the code.

var custNames = LoadCustNames();
var custFirstInitials = (from cn in custNames
select cn.Name.Substring(0, 1).ToLower()
).Distinct();

    foreach (var item in custFirstInitials)
    {

        bool has = list.Contains(item);  
        //the above line of code return true because its checking whether `list.Contains or item.Contails` this will always return true but what i want is something sequence checking the first loop checks for A (found? true) and second loop checks for B (false) and third loop checks for C (false) .......so that i can generate ahref based on whether its return true or false.

        if (has)
        {
            //generate href
        }
        else
        {
            //disable href
        }
    }

i have updated my question and seems like the question was not clear..

so here you go….
i am trying to compare a string[] myArray with a string and if anything is unmatched then store it in a string.

for an example:

i have a list of custName starting with A, S & Z and compare with myArray

string[] myArray = { "a", "b", "c", "d", "e", "f", "g", .... "z"}; 

public class CustNames
{
    public string Name { get; set; } 
    public CustNames() { }
    public CustNames(string name) 
    { 
       Name = name;
    }
}

public List<CustNames> LoadCustNames()
{
    //connect to db and load the data.
    List<CustNames> names = new List<CustNames>
        {
            new CustNames("Alan"),
            new CustNames("Scoot"),
            new CustNames("Shark"),
            new CustNames("Alpha"),
            new CustNames("Zebra") 
        };
    return names;
}

//page_load event....
   //...check for postback....
    for (int i = 0; i < 5; i++)
    {
        string name = LoadCustNames()[i].Name.ToString(); 
        ListItem(name);
    }

List<char> HeaderOf = new List<char>();
protected void ListItem(string cust)
{
    // need a way to compare with myArray... 

    char CheckMe = cust.Substring(0, 1).ToUpper()[0];
    if (!HeaderOf.Contains(CheckMe))
    {
        HeaderOf.Add(CheckMe);
    }
}

Answer 1

Disable it but still leave as href (clicking it won’t do anything but would still look like active link)

b.InnerHtml = "<a onclick='return false;' class='WhateverClassForStyle' href=#" + nextRole.ToUpper().ToString() + ">" + nextRole.ToUpper().ToString() + "</a>";

Don’t display as href

b.InnerHtml = "<span class='WhateverClassForStyle'>" + nextRole.ToUpper().ToString() + "</span>";

Use css class WhateverClassForStyle to style it the way you want.

I guess you are trying to get a list of first initials of customer names.

var custNames = LoadCustNames();
var custFirstInitials = (from cn in custNames
                            select cn.Name.Substring(0, 1)
                        ).Distinct();

custFirstInitials is now IEnumerable<string> and you can do a loop on it or check against it if the href should be made or not.

foreach (var letter in myArray)
{
    if (custFirstInitials.Contains(letter.ToUpper()))
    {
        // Enabled Href
    }
    else
    {
        // Disabled Href
    }
}
