    I am able to update the fields editor and modified by but if the versioning is enabled then after updating the field value I have to publish the item.Once published these field values automatically changes to current date and time which I donot want.I cannot disable versioning

  • Hi,

    then you could write an ListItemEventReceiver where you can catch the Event ItemUpdated and then change the FieldValues and make an item.SystemUpdate.

  • hi

    If I update my field in update event receiver then I think item will change again in draft mode and I have to publish it again which will again modify the field.When I publish the file then my field modified by changes to system account automatically.How can I prevent this change in the field while publishing my item

  • You might want to try this.

    Since you have the SPUser object of the user you want, then open your SPSite with the SPUser.UserToken property in the constructor. Then retrieve the SPFile and call the publish method. The modified by property will be set to that user.

  • I will try but when i publish modified date also changes how can I prevent that?.My modified date should not change but only the modifed by that also the user taken by code but the user will be given by me.

    According to you Steve I will able to publish with the user but not stop updating the modified date field.

  • To prevent modified date to be updated by current date, We need to overwrite it with modifed date before publishing it.

     SPListItem itmNewVersion = fileDest.Item;
         itmNewVersion["Modified"] = dateModifiedOn.ToLocalTime();

          if (libDest.EnableMinorVersions)
