The following is a code sample that calls two methods: GetWorkflowId and ExecuteWorkFlow to run Workflow Programatically either C# or Plug-In :
One important thing to note is that the workflow we are executing must be marked as an on-demand or child workflow; otherwise you will receive an error below.
"Workflow must be marked as On Demand or Child Workflow"
public void Execute(IServiceProvider serviceProvider)
{
// Get Workflow or Process Id
// "Test_WF" = Workflow Name
// "workflow" = Process Schema name
// "incident" = Entity Name on which workflow will run
// "false" = either workflow must be 'ondemand' or 'child workflow'
// 1 = indicate Type of workflow 1-Activate, 2- Draft
Guid processId = GetProcessId(service, "workflow", "Test_WF","incident",false,1).Id;
// Execute Workflow or Process
ExecuteWorkFlow(service, processId, new Guid("BF2184E0-51D4-E311-A7B2-7427EA0AF460"));
}
private Entity GetProcessId(IOrganizationService service,string Process,string WorkflowName,string EntityName,bool IsOnDemand,int Type)
//Internal method used to search for entity records
{
QueryExpression query = new QueryExpression(Process);
query.ColumnSet = new ColumnSet(true);
query.Criteria.AddCondition(new ConditionExpression("name", ConditionOperator.Equal, WorkflowName));
query.Criteria.AddCondition(new ConditionExpression("type", ConditionOperator.Equal, Type));
query.Criteria.AddCondition(new ConditionExpression("primaryentity", ConditionOperator.Equal, EntityName));
query.Criteria.AddCondition(new ConditionExpression("ondemand", ConditionOperator.Equal, IsOnDemand));
try
{
EntityCollection response = service.RetrieveMultiple(query);
if (response != null && response.Entities.Count > 0)
return response.Entities[0];
else { return null; }
}
catch (Exception ex)
{
//Do error handling
throw ex;
}
}
}
private void ExecuteWorkFlow(IOrganizationService service, Guid workFlowId, Guid entityId)
{
try
{
// Create an ExecuteWorkflow request.
ExecuteWorkflowRequest request = new ExecuteWorkflowRequest()
{
WorkflowId = workFlowId,
EntityId = entityId,
};
// Execute the workflow.
ExecuteWorkflowResponse response =
(ExecuteWorkflowResponse)service.Execute(request);
}
catch (Exception ex)
{
throw new InvalidPluginExecutionException();
}
}
Cheerssss :)
