Hi

I have an ASP.NET Page that updates registered User Address Details for a selected record. Below is the Update method that i am calling from Controller.

When i am calling ApplyPropertyChanges method, I am getting the below error. Did anyone run into the same error while updating the record with Entity Framework.

Appreciate your responses.

Error Message:

The existing object in the ObjectContext is in the Added state. Changes can only be applied when the existing object is in an unchanged or modified state.

My Update Method Code:

[HttpPost]
    public bool UpdateAddressDetail([Bind(Prefix = "RegUser")] AddressDetail regUserAddress, 
                        FormCollection formData)
    {
    regUserAddress.AD_Id = 3;
        regUserAddress.LastUpdated = HttpContext.User.Identity.Name;
        regUserAddress.UpdatedOn = DateTime.Now;
        regUserAddress.AddressType = ((AddressDetail)Session["CurrentAddress"]).AddressType ?? "Primary";
        regUserAddress.Phone = ((AddressDetail)Session["CurrentAddress"]).Phone;
        regUserAddress.Country = ((AddressDetail)Session["CurrentAddress"]).AddressType ?? "USA";

        miEntity.ApplyPropertyChanges(regUserAddress.EntityKey.EntitySetName, regUserAddress);
        miEntity.SaveChanges();
        return true;
    }
