Cannot rebind GridView nested in DataList

[H5N1]

Hello everybody

I'm stuck for a long time with the following problem, so I will be
really gratefull if you could help me a bit:

I have a GridView nested in DataList (it's located in DataList's Item
Template together with it's data source).

In OnRowUpdated event of child GridView I'm calling DataBind() on
parent DataList, since I want it to reflect the changes (maybe there's
better way to refresh the datalist?)

I get the following error:
==========
"The ObjectDataSourc e control 'odsGridViewObj ectDataSource' does not
have a naming container. Ensure that the control is added to the page
before calling DataBind. "
==========
It happens when during rebinding of datalist, rebinding of child
gridview is called ( on ItemDataBound event), more precisly when
FindControl is called:

protected void DataList1_ItemD ataBound(Object sender,
System.Web.UI.W ebControls.Data ListItemEventAr gs e) {
odsGridViewObje ctDataSource =
(ObjectDataSour ce)(e.Item.Find Control("odsGri dViewObjectData Source"));

try
{

odsodsGridViewO bjectDataSource .SelectParamete rs["CostID"].DefaultValue
= DataBinder.Eval (e.Item.DataIte m, "CostID").ToStr ing();

}

thank you a LOT

I've solved the problem.

I guess calling DataBind() on parent control on OnRowUpdated() was to
early, so what I did was to set

ViewState["updatingRo w"] = true;

in OnROwUpdated

and start DataBind in the latest phase of page life cycle -
onPreRender, when nested control was already bound programmaticall y to
parent:
protected override void OnPreRender(Eve ntArgs e)
{
base.OnPreRende r(e);

if ((bool)ViewStat e["updatingRo w"])
{
DataList1.DataB ind();
ViewState["updatingRo w"] = false;

}

}
cheers
