>You can't get at controls inside templates in the
OnItemDataBind event, since that creates the
ObjectListItem objects that contain the items to be
displayed in the list.
>The controls that are in the templates are created after
the data binding has completed. You have to find the
template container control for the item you want to
change, and inside that template container will be the
Label control you want to program.
>Within an ObjectList control, the templatecontainer is
the ObjectListItem controls, so if you walk through the
ObjectList's Controls collection, you're walking through
the collection of template containers. Then, for each
ObjectListItem, you can use FindControl to locate your
Label, and set properties of it.
>
>For example, If you have an ObjectList defined like this:
>
><mobile:Form id="Form1" runat="server">
> <mobile:ObjectList id=ObjectList1 runat="server"
> CommandStyle-StyleReference="subcommand" LabelStyle-
StyleReference="title"
> DataSource="<%# dataSet11 %>" DataMember="authors">
> <DeviceSpecific>
> <Choice
Xmlns="http://schemas.microsoft.com/mobile/html32template...
> <ItemTemplate>
> <%# DataBinder.Eval(((ObjectListItem)
Container).DataItem, "au_lname") %>
> <br>
> <mobile:Label id="Label1"
runat="server">LabelInTemplate</mobile:Label>
> </ItemTemplate>
> </Choice>
> </DeviceSpecific>
> </mobile:ObjectList>
></mobile:Form>

>(I just used the pubs database in the SDK MSDE for the
data).
>Then to get at the Label1 in each ObjectListItem, one
technique you an use is to trap the OnPreRender event and
walk the collection of ObjectListItem objects in there -
by then the templated controls have been created, so you
can get at them:
>
>private void ObjectList1_PreRender(object sender,
System.EventArgs e)
>{
> //Walk through the controls in the ObjectList
> //This control is a ObjectListItem, which is also the
template container
> int itemcounter = 0;
> foreach (ObjectListItem item in ObjectList1.Controls)
> {
> System.Web.UI.MobileControls.Label label1 =
item.FindControl("Label1")
> as System.Web.UI.MobileControls.Label;
> if (label1 != null)
> {
> //test because label is in template - may not be
there for some clients
> label1.Text = "Set in code"
> }
> itemcounter++;
> }
>}
>
>Hope that gives you what you want.
