Re: Update one item in a BindingList

EitanB,
You should cycle through the items using the indexer, and not foreach,
like so:
for (int index = 0; index < myList.Count; ++index)
{
// Get the item.
MyStruct myStruct = myList[index];
// Modify the item here.
// Assign the item back.
myList[index] = myStruct;
}
The reassignment is necessary as you are working with what I assume is a
value type, so accessing properties off instances of that type returned by
the indexer would not change the value in the list.

Please look at the code and the following question...
public BindingList<MyStruct> myList ;
foreach ( Object item in myList )
{
MyStruct myStruct = (MyStruct)item;
myStruct .Name = "any new name" ;
///
/// Question: I need to update myList with the updated myStruct, how is
the
most
/// efficient way to replace/update the old item in the
list
}
Thanks
