Vista Tutorial - Manual population of listview

Hi,

pulling out whats left of my hair...

Assuming I have a simple xaml file with a listview, or even some other
placeholder, does anyone have simple code to demonstrate manual (eg cell by
cell, row by row) population of a listview?

I can certainly programmatically create all I need including GridViewColumn
headers and ListViewItem objects, BUT ListViewItem exposes only a simple
Content property of type object, and I can not figure out how to provide the
cell information to correspond with the column/header definitions.

Can anyone help please!?

Normally you specify the content of the ListView by setting the ItemSource
property of the Items property. You can see good examples of that here:
http://msdn2.microsoft.com/en-us/lib....listview.aspx
http://blogs.msdn.com/atc_avalon_tea...23/537715.aspx

Alternatively you can add row by row, a brief step by step here:

1. Assuming you have a custom class (Employee) that exposes properties for
FirstName and LastName.
2. Add two GridView columns.
3. On the first one set col1.DisplayMemberBinding = new
Binding("FirstName");
4. On the second one set col2.DisplayMemberBinding = new
Binding("LastName");
5. Create an instance of your custom object, like:
Employee emp = new Employee();
emp.FirstName = "Joe";
emp.LastName = "Doe";
// Next add to the ListView
MyListView.Items.Add(emp);

That should do it.

Hi,

thanks for that. I am glad someone is listening. My problem is one of
abstraction and UI - Business Object separation.

I have a sever that exposes only Web Services, and behind that of course is
a wonderful world of Business Objects, ORM, etc.

Now on the client I have WPF - the Presentation Layer. I need to be able to
handle very dynamic data on the client; the Business Objects do not exist
client side - only the data. The WebService may publish an XML document
that carries data+metadata (eg column Names/types/widths etc). I need to
respond to the metadata by dynamically creating columns in the GridView, and
publishing the data as well. All formatting, business rule execution etc
happens on the server. The client only has a remote URL to talk to, and is
very very "thin".

I have managed to get a XmlDataProvider working, but now I am having trouble
with Templates; is there a programmatic way of creating a DataTemplate with
dynamic binding?

Cheers, and thanks again,

Radek

You can programmatically use the DataTemplate class. First you have to
create the VisualTree of elements for the template and then you can
dynamically bind your XML data.

Here are two examples, I believe the combination of both will give you all
necessary to understand and implement the concept:

Hi Plamen,

I've had a quick look at the links and they look very promising... will keep
you posted.
