DataList : get values

[SJ]

I have a dropdownlist("myList") in my DataList control. When a user selects
one of the
items in the dropdownlist, I need to access the value of the DataBound Label
("myLabel") in the Datalist and display it in a popUp window. I have to do
all of this in Codebehind and not inline scripting. Any idea how I can
accomplish this?

<aspataList id="testList" runat="server">
<ItemTemplate>

<aspropDownList id="myList" runat="server">
<asp:ListItem value="Item1"></asp:ListItem>
<asp:ListItem value="Item2"></asp:ListItem>
</aspropDownList>

<asp:Label id="myLabel"><%# DataBinder.Eval(Container.DataItem,
"DataValue")%>
</asp:Label>

</ItemTemplate>
</aspataList>


Thanks.

DropDownList ddl =
(DropDownList)datalist.Items[rowIndex].FindControl("myList");
string strValue = ddl.SelectedValue;

That kind of helped. thanks.
I'm trying to do this in the "myDataList_SelectedIndexChanged" event
handler.
for some reason though, when I select something in the dropdownlist, nothing
happens.

DropDownList ddl =
(DropDownList)datalist.Items[rowIndex].FindControl("myList");
string strValue = ddl.SelectedValue;

Do you have event trigger:

this.myDataList.SelectedIndexChanged += new EventHandler(myDataList
_SelectedIndexChanged);

in method private void InitializeComponent() ?

That kind of helped. thanks.

Yes, its there.
Do I have to use RaiseBubbleEvent so that a change in the DropDownlist
inside the
DataList actually works? If so, how do I do this?
Or is there another way to do this?

Just a guess, your Datalist’s EnableViewState is set to false. That might
cause this kind problem.
