I cannot reference a calendar control in my formview control. (I want the
calendar's date to be set to "Today" whenever they enter insert mode.)

Here's part of the formview...
<asp:FormView ID="FormView1" runat="server" CellPadding="4"
DataKeyNames="ListingId"
DataSourceID="sdsListingDetails" ForeColor="#333333">
:
:
<InsertItemTemplate><table cellpadding="0" cellspacing="0"
width="700">
:
:
<tr>
<td style="width: 166px" valign="top">
Bid Deadline:</td>
<td>
<asp:Calendar ID="calDeadline" runat="server"
Height="165px" SelectedDate='<%# Bind("LBidDeadline") %>'
Width="259px"></asp:Calendar>
</td>
</tr>
:
:
</InsertItemTemplate>
:
:
</asp:FormView>

Here's the code:
Protected Sub FormView1_ModeChanged(ByVal sender As Object, ByVal e As
System.EventArgs) Handles FormView1.ModeChanged
Select Case Me.FormView1.CurrentMode
Case FormViewMode.Insert
Dim cal As Calendar =
CType(Me.FormView1.FindControl("calDeadline"), Calendar)
cal.SelectedDate = Now.Date
End Select
End Sub

The variable 'cal' is "Nothing" everytime I set it! In fact, I cannot
reference any textboxes in the formview as well.

I know it's probably something simple.

Any ideas?
 
Hello Cirene,

What's the calendar control name in the page source, when page is rendered?

thats because they are children of the template which is a child of the
formview. so you need to do a recursive find (find children of children ...)

Here's some of it... calDeadline seems correct???

<a
href="javascript:__doPostBack('ctl00$ContentPlaceHolder1$FormView1$calDeadline','2857')"
style="color:Black" title="October 28">28</a></td><td align="center"
style="width:14%;"><a
href="javascript:__doPostBack('ctl00$ContentPlaceHolder1$FormView1$calDeadline','2858')"
style="color:Black" title="October 29">29</a></td><td align="center"
style="width:14%;"><a
href="javascript:__doPostBack('ctl00$ContentPlaceHolder1$FormView1$calDeadline','2859')"
style="color:Black" title="October 30">30</a></td><td align="center"
style="width:14%;"><a
