Custom Delegation Form

changing AssignedTo task item field doesn't cause the task is delegated to new assignee!

so s/he's not authorized to respond

if you need to have control over task delegations you either need to call 'Delegate Workflow Task' workflow action or call 'DelegateTask' method of Workflow.asmx webservice.

In my scenario the solution will not work. Actually I am using "Request Approval" Task, here I have enabled delegation. Instead of SharePoint delegation form I have used my custom delegation form.

In my organization web services calls blocked.

Please let me know, is there any other way or what parameters need to updated using spservices call?

go on with first approach.

let the custom form save a 'Deletage request' to a dedicated list. configure a workflow on the list that starts when item is created. let the workflow delegate task using workflow action

Thank you for your continues support. As you said, I have tried below approach. Workflow Completed, but in workflow task list not updating assign to. Please let me know, is there any mistaken my end.

Below is my actual workflow image.

you seem to try to delegate task by a TaskID. 

Delegate task requires ActionID parameter to identify the task.

you have to capture respective ActionID within the Request Approval action

Thank you so much solution working :-) now i got lot of confidence on delegation. once again thank you.

great!
