How to pass parameters from workflow to activity properties?

I've created a custom activity with 3 properties (p1,p2,p3) all of them System.String.
I'm using that activity in a workflow with parameter wfp1.
How can I put the value of wfp1 into p2 using the visual designer?

Regards.

Hi, You need to bind the activity property with the workflow parameter so that you can pass the value. For sample code please refer to http://forums.microsoft.com/msdn/ShowPost.aspx?PostID=96331

Hope this helps.

How can I bind it if I have a pure code based workflow , no .xoml file ?

would this work ?



activitybind2.ID = "/Parent";
activitybind2.Path = "Parameters[myItemId]";
this.createItem1.SetBinding(Spikes.WWF.Ressearch.ActivityLib.CreateItem.ItemIdProperty, ((System.Workflow.ComponentModel.Bind)(activitybind2)));

Almost. You need to say

activitybind2.Path = "Parameters[myItemId].Value";

Thanks,
