  1. POHow can I create WF rules in code?
    text
    copied!<p>I'm creating an <strong>ActivityToolboxItem</strong> for a custom Activity in WF. I'm trying to do as much work as possible for the designers within the CreateComponentsCore method. What I'm trying to end up with is the following:</p> <p>1) My custom activity (<strong>TriggerActivity</strong>, a <em>SequenceActivity</em>), containing the following:<br> 2) A <strong>TriggerEvaluatorActivity</strong> (a simple <em>Activity</em>), which is bound to a property on the TriggerActivity<br> 3) An <strong>IfElseActivity</strong>, which has two branches<br> 4) An <strong>IfElseBranchActivity</strong> that contains<br> 5) A <strong>TerminateActivity</strong>, and<br> 6) An <strong>IfElseBranchActivity</strong> that is empty, through which execution flows when the TriggerEvaluatorActivity evaluates to true.</p> <p>Designers switch out the <strong>TriggerEvaluatorActivity</strong> with one or more implementations that perform complex evaluations against an execution context. </p> <p>Its pretty simple to set this up in code, but I'm completely stuck on how to spin up an <strong>ActivityCondition</strong> that will be added to the <em>IfElseBranchActivity</em> to control the flow of execution.</p> <p>All I need to do is evaluate a property on the <strong>TriggerEvaluatorActivity</strong>. I've created a nice lovely Rule via the code dom, but I can't set that directly on the <em>IfElseBranchActivity</em>, I have to stash the rule somewhere and reference it in the activity.</p> <p>So, I guess my question is, once I've created a rule in code, how do I add my rule to the workflow from within a custom ActivityToolboxItem so that the activities I build in code can reference it?</p>
