Yes, you can do that with a little trick.

1. Show the distinct first later of employees from DB
Query like following can help to do so

SQL

SELECT DISTINCT LEFT(EmployeeName,1) FROM dbo.Employee

2. Show this with the help of a repeater control like

ASP.NET

<asp:repeater runat="server" id="repDemo" xmlns:asp="#unknown">
            <itemtemplate>
                <asp:linkbutton id="lnkDemo" text="<%#Eval("EmployeeName") %>" runat="server" onclick="lnkDemo_Click" />
            </itemtemplate>
        </asp:repeater>

3. Code behind should look like

C#

protected void lnkDemo_Click(object sender, EventArgs e)
    {
        //get the letter for which you will show the employee name
        string serachLetter = ((LinkButton)sender).Text.Trim();
        //logic to query and show the employee names starting with the 'searchLetter'
    }

2. While selecting an item from dropdownlist first show employees with name starts with 'A'
3. Then if user clicks on any other letter he/she can view the desired result

Hopefully this will help.
In case any further assistance is required please let me know :)

Solution 1

You can use Linq to get a sorted list based on a target string.

C#

 string[] names = { "Tom", "Dick", "Dan", "Tony", "Tim" };
 string key = "D";
 List<string> ListSortedByKey = names
 .Where(n => n.StartsWith(key))
 .OrderBy(n => n).ToList();
</string>
