asp.net - VB.NET Repeater Simple Data Binding Without Datasource

Question

I've got a form that has to be a repeater on a webpage. I have a number parameter that tells me how many additional customer details are to be added. In this page I have a repeater control that needs to repeat items a set number of times. For each item there is a set of input boxes that needs an id appended to it. All I need to bind is a number for each additional input box ie <% #id %>. I dont know how to set up simple databind without a specific datasource, but just build one in a loop.

<asp:Repeater ID="myRepeater" runat="server"> 
    <HeaderTemplate>  
       <div class="AdditionalRowTitle">
            <div class="AdditionalCellTitle">Title</div>
            <div class="AdditionalCellFirstName">First Name</div>
            <div class="AdditionalCellLastName">Last Name</div>
            <div class="AdditionalCellDOB">DOB</div>
            <div class="AdditionalCellRelationship">Relationship</div>
        </div>
    </HeaderTemplate>

    <ItemTemplate>
       <div class="AdditionalRow">

Answer 1

Here's a way to repeat the items. In your page load event, add the following:

Dim repeatTimes() As Integer = New Integer(){1, 2, 3}
myRepeater.DataSource = repeatTimes
myRepeater.DataBind()

The repeater items will be repeated by the number of elements in the Array. In this case, there are 3 elements. The actual contents of the array don't matter, just the number of elements.

EDIT: I don't know VB.NET that well, but I think this should work

Sub Page_Load()
  Dim NumberToRepeat As Integer ''*Should come from the parameter
  If Not Page.IsPostBack Then
    Dim repeatTimes(NumberToRepeat) As Integer
    myRepeater.DataSource = repeatTimes
    myRepeater.DataBind()
  End If
End Sub
