Hello all,

I am searching for some time now in this forum as well as in other sites (e.g. Stackoverflow) for a solution on following problem: A datagrid is bould to an ObservableCollection<T>. One of the properties of <T> is an ObservableCollection<T1>.

One record represents the workload of a worker per day. it is possible that the worker is assigned to multiple tasks on one day.

In this case I would like to show the record of the day and in one cell the assigned tasks for this day.

This works fine witha template field and a listview.

The problems are:

1. How can I set the size of the columns of the ListView that each of them use 50% of the space inside the TemplateField?

2. How can I make the second column of the ListView (TaskMemo) editable?

Thanks in advance!

Niko
