Because you are doing a ToString() on the object. You would need to use the objects porperty value.
e.g.
var value=additem.SelectedItem as YourObject; //YourObject is the object type which is the databound for each item
text1.text = value.PropertyInYourObject;
You can do it in XAML itself also, databinding the Text property of text1. See if this works,
Text = ="{Binding ElementName=additem,Path=SelectedItem}"

Hi all,

We develop classic business applications (relational DB, GUI etc.). We are considering implementing our business processes using WF.
We consider WF as a means of simplifying development and making maintenance of complicated logic easier (Persisting, multiple async users, etc. are not relevant. The WF replaces a synchronous call to a static method).
During the few weeks we have tested it we found out it does have some quirks and we also learned about the expected, totally different, ver 4 (though we cannot wait for it).
We have not been able to find someone with actual working experience that can tell us weather working with this technology actually pays back.

Can anyone help from their own experience?

Thanks,

Asher

I don't know that you are going to get very many responses but here's mine. About 2 years ago I had to implement several business processes in MFC. It was a nightmare and took a couple of months to get it worked out. My latest project is using WPF, WCF and WF. I decided to try WF for the processes that I had to do before and see if it would work for us or not. The first workflow took maybe 3 days to create and worked the way I expected the first time out. I have had to add things to it but the core has remained the same since. Worked out really great for me. The second workflow took less than 1 day to create the base. I had to shift to other priorites so it's not quite finished but I expect that I could finish it in a couple of hours. So the WF has worked out fine for me and I think that I am going to stick with it unless I discover some really compelling reason to switch.

The big caveat here is that that I am not using any of the more advanced features of WF as yet. I am just doing some really basic stuff.

Why is common sense not common?

you will need to declare the 'ctrl' namespace in your XAML namespaces.

Binding connections

Hello everyone,

I made some progress. I use ItemsControl, DataTemplates an I can move my nodes over canvas.

Code:

public class NetworkNode
{
        string Caption;
        string Type;
        int ID = 0;
        int X = 0;
        int Y = 0;
}

public class EndNode : NetworkNode {}
public class RouterNode : NetworkNode {}

public class Connection
{
        int StartNode = 0;
        int EndNode = 0;
}

Xaml:

<ItemsControl>
  <ItemsControl.Items>
    <cc:EndNode    ID="0" Caption="Node" X="70" Y="20"/>
    <cc:RouterNode ID="1" Caption="Router" X="220" Y="120"/>
    <cc:EndNode ID="2" Caption="Router" X="120" Y="50"/>

    <cc:Connection StartNode="0" EndNode="1"/>
    <cc:Connection StartNode="1" EndNode="2"/>
  </ItemsControl.Items>
</ItemsControl>

Now I try to solve how to connect the nodes. The problem is I want to data bind two nodes according to their ID's. This functionality provides for example Graphite for WPF (http://www.orbifold.net/default/?p=1326) but the source code is not available. I guess some binding converter will be required as well as multiple binding. But for me as beginner is hard to put all pieces together. Any ideas? Thank you.
