Changing the SPWorkflowAssociation.AutoCleanupDays property

By default the SPWorkflowAssociation.AutoCleanupDays property value is set to ‘60’ days, to set this property we need to call the SPList.UpdateWorkflowAssociation(SPWorkflowAssociation) function, SPWeb.Update() won’t work here.

 

    1: SPSite site = new SPSite("<https://nishandv3:100/sites/DevSite/>");

    2: SPWeb web = site.OpenWeb();

    3: SPWorkflowTemplateCollection collection = web.WorkflowTemplates;

    4: SPList list = web.Lists["Shared Documents"];

    5: SPWorkflowAssociation _asso = null;

    6: foreach (SPWorkflowAssociation asso in list.WorkflowAssociations)

    7: {

    8: if (asso.Name == "Approval")

    9: {

   10: asso.AutoCleanupDays = 100;

   11: _asso = asso;

   12: }

   13: }

   14: list.UpdateWorkflowAssociation(_asso); 

 

Hope this works for you!
