SPFieldChoice to the dropdown list programatically:

1. List Name: MyList
2. Choice Field Name: MyChoiceField and the values are
1. MyChoice1
2. MyChoice2
3.  MyChoice3

First example to set the SPChoice field default value as dropdown list default value.

          try
            {
                using (SPSite site = new SPSite(SPContext.Current.Site.ID))
                {
                    SPWeb web = site.OpenWeb(SPContext.Current.Web.ID);
                    SPList liMyLists = web.Lists["MyList"];
                    SPFieldChoice fcTypes = (SPFieldChoice)       
                                                liMyLists.Fields["MyChoiceField"];
                    ddlChoiceField.DataSource = fcTypes.Choices;
                   //To set choice field default value as dropdown list default value.
                    ddlChoiceField.SelectedValue = fcTypes.DefaultValue; 
                    ddlChoiceField.DataBind();
            }
            catch (Exception ex)
            {
               //code
             }

Enhancements in event receivers in SharePoint 2010

Before learning new enhancements in sharepoint2010, we have to know why they were enhanced. So that we can remember new features easily, below are the limitations on sharepoint2007 what I covered in my development career.

• Cannot hook the events to a particular SharePoint lists.
• Need to use standard pre-defined error page when canceling the events, which is not so intuitive for the end users
• No JavaScript alert instead of redirecting to pre-defined error page
• No events for SPWeb object.
