Dodam ze reprezentacja tego pola w templateitem ale w widoku "normalnym" bez
edycji jest labelka.
Masz moze jakis pomysl jak to obejsc? Idealnie chcialbym uzyskac
wspolzaleznosc pomiedzy 2 osadzonymi gridview tak aby wybranie rekordu z
jedego powodowalo zawezenie wynikow 2-giego. Oczywiscie te 2 kontrolgi sa
embedded.

Czesc Darek,
What about FindControl() method?:
DropDownList dropDownList = (DropDownList)
DetailView1.FindControl("DropDownList1")
string selectedValue = dropDownListSelectedValue;
or use asp:ControlParameter in sqldatasource control. The only problem
with
the second approach (in this case) is you have to provide container(s)
control id as well:
<asp:SqlDataSource runat="server" ID="SqlDataSource1">
<SelectParameters>
<asp:ControlParameter ControlID="DetailsView1$DropDwonList1"
PropertyName="SelectedValue"/>
</SelectParameters>
</asp:SqlDataSource>
Hope this helps

>Hello,
The situation is like follow:
I've got GridView1 correlated with DetailsView1 (it's normal scenario).
In
DetailView1 I've got CRUD operations enabled. For create and edit
opeartion
I've 2 ItemTemplates. One of them is DropDownList2 (with AutoPostBack
enabled) and 2-nd one is GridView2 (dependent on DropDownList2). All I
want
is to have GridView2 updated when I change option in DropDownList2.
I thought that I can do that in code behind (Selected event of
DropDownList2) by changing SqlDataSource which is bound to GridView2. But
I
don't know how to refer to these "embedded" controls.
Best Regards
