add value to text field in list with ItemAdded event receiver

Question

i have a textfield in a list, that i want to fill with custom text when a item is being added. nothing happens when i try to debug it, the breakpoint in the method is never reached.

Please can someone provide me with some example code about how to accomplish this.

Answer 1

first create one event receiver, sample code (not tested, just to give some basic idea)

public class YourClass: SPItemEventReceiver
{
   public override void ItemAdded(SPItemEventProperties properties)
   {
      SPListItem item=properties.ListItem;
      item["YourFieldNameInWhichYouWantToPlaceCustomText"]="Custom Text";
      //any other logic
      item.Update(); //must!!! or you can use item.SystemUpdate() also based on your requirement
   }
}

then create another feature receiver

public class MyFeatureReceiver: SPFeatureReceiver
{
public override void FeatureActivated(SPFeatureReceiverProperties properties)
    {            
            SPWeb web = properties.Feature.Parent as SPWeb;
            if (web != null && web.Lists["YouList"] != null)
            {
                web.Lists["YourList"].EventReceivers.Add(SPEventReceiverType.ItemAdded,
                    "Featurename, Version=1.0.0.0, Culture=neutral, PublicKeyToken=token",
                    "EventReceiverClass");
            }            
    }

    public override void FeatureDeactivating(SPFeatureReceiverProperties properties)
    {            
            SPWeb web = properties.Feature.Parent as SPWeb;

            if (web != null && web.Lists["YourList"] != null)
            {
                SPEventReceiverDefinitionCollection Recievers = site.Lists["YourList"].EventReceivers;
                //delete event receiver or perform some other activity
            }            
    }
}

that's all in a nutshell, if you dont have explicit reason, i would suggest go with ItemAdded rather than ItemAdding, ItemAdding shoudl be used only when synchronous activity is required, if you still face problem kindly post your code here

this first popped from googling it: http://msdn.microsoft.com/en-us/library/ms437502.aspx

Which event are you using? ItemAdded or ItemAdding? This seems to be the common issue...
