Hi, We use tracking and persistence services of wf, and display current state of workflow on the asp.net page. Now in the process of localization of our application, we are able to localize all elements on the page except the activity names of workflow. These activity names are given while creating a workflow in VS 2008. How do i ach...
This is the scenario: I have a State Machine Workflow using ManualWorkflowScheduler. Say there are 2 states: State1 and State2. State1 contains an EventDrivenActivity1 that has a SetStateActivity1 moving the workflow from State1 to State2. State1 also has a StateFinalizationActivity1. So my question is: When an event is raised and Set...
I am trying to implement an activity similar to InvokeWorkflow, which could dynamically load a XOML file, instantiate an activity tree from it, and use it as its only child. This would be similar to InvokeWorkflow except that the activities which are dynamically loaded are inlined into the main workflow (which is better from a monitorin...

Hi All, In my application, I have 2 list activities which can start one or the other by clicking on their items. |--Activity1--| |--Activity2--| |--Activity1--| | item11 | ->click-> | item21 | | item21 | ->click-> ... | item12 | | item22 | ->click-> | item12 | | ...
I have implemented a queuing mechanism including UI for running specific types of workflows (WF 3.5), where I wanted to include a possibility for a user to cancel / terminate the workflow. The termination doesn't have to be synchronous, it would be enough to show that the cancellation is in progress and let him refresh the state later. ...
I have a workflow activity that is responsible for checking if a certain part of the infopath form was filled out correctly. If it wasn't it creates a task for the original submitter to complete that section. The workflow starts with a CodeActivity that reads in the document and checks if it is valid. If not it then creates a task for...
Hi all. I'm quite new to Workflow and have a question. I have a While Loop in my designer which checks a conditon. The while loop works fine and the condtion checking works fine. What I'm trying to do, is to set a delay so that the while loop only checks the condition every x seconds/minutes. I've tried the delay control inside the wh...
I have a workflow with a parallel activity, where one branch does work and the other has a receive activity that can shut the workflow down (is the proper way to do this with a HandleExternalEvent instead?). The problem, of course, is that if the receive activity is never called, the work branch completes and waits on the receive activi...
Hi, so I have this requirement to kick off Activities provided to me at run-time. To facilitate this, I have set up a WorkflowService that receives Activities as Xaml, hydrates them, and kicks them off. Sounds simple enough ... ... this is my WorkflowService in Xaml <Activity x:Class="Workflow.Services.WorkflowService.WorkflowSe...
I would like to bind multiple dependency properties of other activites to a dependency property (of type object[]) in my custom activity. Is it possible to define this multibinding : In the workflow markup (probably somehow combining multiple ActivityBind's) Set up the property editor in such a way that I can even edit this binding in...
I have a Sequence Activity which holds two activities (Activity A and B), the input dependency property for Activity B is bound an output dependency property of Activity A. However, when I run the sequence activity, the Input for activity B is never updated and just uses the default value of activity A's output. My question is: is ther...
I have a WF service with a custom activity and a custom designer (WPF). I want to add a validation that will check for the presence of some value in the web.config file. At runtime I can overload void CacheMetadata(ActivityMetadata metadata) and thus I can do the validation happily there using System.Configuration.ConfigurationManager t...
When my app starts, it checks to see if it has stored login credentials. if it doesn't, it starts another activity to prompt the user for those credentials. My problem is, that when the prompt activity is started, the first activity continues execution and ends up with null pointers because the prompt activity has not yet returned the ne...
I'm creating a custom Workflow activity for use within TFS2010. In the same assembly I have a XAML activity and a C# code activity. The XAML activity references the code activity. When the assembly is deployed to our clients, I only want them to be able to use the Workflow activity. The code activity is of little use by itself and woul...
