I am creating an employee list with employee names listed under departments.

Executive
Mary Lamb
Ted George
Budget
Money Man
Deputy Paul

My datatable returns the department name for each person. How do i get it just once until it changes.

I havent really tried anything because I dont know how to do a comparison

Thank you!

What I have tried:

VB Code

If Not IsPostBack Then
           Dim dt As New DataTable()

           Dim groupid As Integer = 106
           Dim campusname As Label
           Dim campusnameCUrr As String = ""
           Dim campusNamePrev As String = ""

           'Dim lblCampus As Label = dlStaff.FindControl("lblcampus")
           Dim cmd As New SqlCommand("proc_Directory_Select_Full_byGroupId_test", strConn)


           cmd.CommandType = CommandType.StoredProcedure
           cmd.Parameters.AddWithValue("@Id", groupid)
           strConn.Open()
           Dim da As New SqlDataAdapter(cmd)
           da.Fill(dt)
           staff.DataSource = dt
           staff.DataBind()


           strConn.Close()
       End If

Asp.net code

<asp:datalist id="staff" runat="server">
  <itemtemplate>
      <asp:label id="campusname" runat="server" text='<%#Eval("campusname") %>' ></asp:label>
  </itemtemplate>

   </asp:datalist>

We don't know - and we can't tell you what to do.
The problem is that you are using a stored procedure we don't have access to to access data in tables we have no access to, to retrieve data we have no idea about (and your sample doesn't help - I have no idea if that is one row of 6 columns, or 6 rows of one column).
And then you need help with changes that don't make any sense either.

Remember that we can't see your screen, access your HDD, or read your mind - we only get exactly what you type to work with, we get no context other than that.

You need to start by learning how to ask a question - no, I'm serious - because at the moment all of the questions you have asked assume a lot of information that you are privy to and that we aren't. Think of it this way: assume your car breaks down in the middle of nowhere and you ring the garage. You say "My car broke down, please come and fix it" then turn off your phone. How long are you going to be waiting until somebody arrives with the right bits to fix your exact car?

Go here: Asking questions is a skill[^] and read it really carefully. Then think about yoru problem and how you need to ask total strangers for help!
