Hi guys,
Am using asp.net 2.0 (VB), I would like to call a text box in the details view control i.e

asp code

XML

<insertitemtemplate>
  <asp:TextBox ID="tdate1" runat="server" Text='<%# Bind("To_Date") %>'></asp:TextBox>
</InsertItemTemplate>
<InsertItemTemplate>
  <asp:TextBox ID="fdate2" runat="server" Text='<%# Bind("From_Date") %>'></asp:TextBox>
</InsertItemTemplate>

vb code

VB

Dim tdate, fdate As Date
'Where tdate1 &fdate2 are controlID's in the detailsview
tdate = tdate1.date
fdate = fdate2.date
Dim ts As TimeSpan = tdate.Subtract(fdate)

Your help will be appreciated.

Larsh.

How do I refer to a text box in the details view control?

Ok. Did you try something like:

VB

Dim tempTxtSome As TextBox = CType(myDetailView.FindControl("txtSome"), TextBox)

This line of code is at the time when you are accessing record-by-record.

Use VS debugged and see what is NULL and you need to make sure that it is initialized properly before using.
