DetailsView: Change TemplateField properties dynamically (vb)

[sck10]

Hello,

I am trying to programically make the following TemplateField ("MyTemplate ")
visible when the user clicks on the "Edit" Button using the PreRender handle
event. My question is, how do you reference the properties of a particular
TemplateField? For example:

Protected Sub dvDetail_PreRen der(ByVal sender As Object, ByVal e As
EventArgs) Handles dvDetail.PreRen der
If Me.dvDetail.Cur rentMode = DetailsViewMode .Edit Then
MyTemplate.Visi ble = True
End If
End Sub
<asp:TemplateFi eld
Visible="false"
HeaderText="Act ivity Date">
<ItemTemplate >
<asp:Label ID="lblActivity Date" Text='<%# Eval("ActivityD ate",
"{0:d}") %>' Runat="Server"/>
</ItemTemplate>
<EditItemTempla te>
<asp:TextBox id="txtActivity Date" Text='<%# Bind("ActivityD ate",
"{0:d}") %>' Runat="Server" />
</EditItemTemplat e>
</asp:TemplateFie ld>

Ctype(sender,Da taGrid).Columns (i).Visible= False

Hi Sck10,

Regarding on the problem you mentioned, we can access all the Fields we
defined in DetailsView control through its DetailsView.Fie lds Property
(through index..)

And of course we can change a certain one's Visble propety. However, as you
mentioned that what you need is hidden the TemplateField in normal status ,
but make it visible when DetailsView turn into Edit mode, yes? If so, we
can just put UI controls in that templateField's "EditTempla te" and put
nothing in "ItemTempla te" , thus there will only displaying UI for that
TemplateField in edit mode. Does this also meet your requirement?

If there're any other questions on this, please feel fee to post here.

Thanks,

Steven Cheng
