Here is the code I have to record the date when the workflow status on an item has been updated/changed. I created accustom column named Completed Date as a Date type in the list to display the date.
The workflow deploys fine but does not render any data under the Completed Date Column. Am I missing something?
namespace WorkflowDateRecorder.EventReceiver1
{
/// <summary>
/// List Item Events
/// </summary>
public class EventReceiver1 : SPItemEventReceiver
{
/// <summary>
/// An item is being updated.
/// </summary>
public override void ItemUpdating(SPItemEventProperties properties)
{
base.ItemUpdating(properties);
if (properties.BeforeProperties["Wokflowstatus"] != properties.AfterProperties["Wokflowstatus"])
{
properties.ListItem["Completed Date"] = DateTime.Now;
properties.ListItem.Update();
properties.Web.Update();
}
}
}
}
In ItemUpdating method, you should be setting your new field value using
properties.AfterProperties[Completed_x0020_Date] = newFieldValue;
//AfterProperties and BeforeProperties are using internal names of columns.
Also question is then, if your if statement is ever visited? Cause calling ListItem.Update() most probably would result in recursive call on this event receiver.

I have an MVC Web API project which is all working fine, but for some reason the entries in the help docs for just one of the controllers does not appear.
This was all fine until just recently, unfortunately though I don't know at what point it disappeared but it definitely used to be there.
The XML comments all look ok.
The XmlDocument.xml file looks correct.
Is there a way to specify which controllers and methods feature in the help docs?
How can I make sure the actions for this controller appear?
In case it helps, this is a snip with the first action:
public class UserController : ApiController
{
/// <summary>
/// Get details of a user or all users, including accounts and group memberships
/// </summary>
/// <param name="username">The name of the user, if a single result is required</param>
/// <param name="account">The account id, if multiple results are required</param>
/// <param name="offset">The first row to return</param>
/// <param name="limit">The maximum number of rows to return</param>
/// <param name="sortby">The column to sort by, if required</param>
/// <param name="order">The sort order; asc[ending] (default) or desc[ending]</param>
/// <returns>Response structure including status and error message (if appropriate), as well as User structure including account and group details</returns>
[Route("user")]
[CombinedAuthentication(AuthLevel = "2")]
[HttpGet]
[AcceptVerbs("GET")]
public UserGetResponse Get(string username = "", int account = 0, int offset = 0, int limit = 0, string sortby = "", string order = "")
{
if (!string.IsNullOrEmpty(username))
{
return new UserGetResponse(username);
}
else
{
return new UserGetResponse(account, offset, limit, sortby, order);
}
}
}
This bit stops the help docs entry being generated:
[AcceptVerbs("GET")]
I removed that and all was fine!
I have a property in my View Model
public const string WelcomeTitlePropertyName = "WelcomeTitle";
private string _welcomeTitle = string.Empty;
/// <summary>
/// Gets the WelcomeTitle property.
/// Changes to that property's value raise the PropertyChanged event.
/// </summary>
public string WelcomeTitle
{
get
{
return _welcomeTitle;
}
set
{
RaisePropertyChanging(WelcomeTitlePropertyName);
_welcomeTitle = value;
RaisePropertyChanged(WelcomeTitlePropertyName);
}
}
This is hooked up to a textbox and has 2 way binding.
Now I have a KeyDown event that I need to get the current length of the "WelcomeTitle" property
public ICommand AutoComplete
{
get
{
return new RelayCommand<KeyEventArgs>(e =>
{
var length = WelcomeTitle.Length;
});
}
}
Yep what I am finding is that WelcomeTitle property does not get updated till the user leaves the textbox. This does not work for me as I need to know the length(and later the current value in WelcomeTitle) and keydown.
How can I get around this? In codebehind this is no problem.
In WPF it would be easily achieved by setting UpdateSourceTrigger="PropertyChanged" in the binding; unfortunately, this is not possible with Windows Phone, so you need a workaround. A few options are described in this question.
I will have many Roles, and each Role has many functions, so the RequireRoles Attribute I don't think will suffice in my case. I need some way to dynamically let the Controller action define to the View what sections and/or controls in the View (without adding if/else logic inside the View).
My thought is that the Controller should be telling the View how to present itself and not the View with the if/else logic.
Any ideas on how to design this ?
You need to first of all create a filter which you can use an attribute to control what roles see what actions. See http://www.asp.net/mvc/tutorials/older-versions/controllers-and-routing/understanding-action-filters-cs.
public class RequiresRoleAttribute : ActionFilterAttribute {
private List<string> requiredRoles = null;
/// <summary>
/// Initializes a new instance of the <see cref="RequiresRoleAttribute"/> class.
/// </summary>
/// <param name="roleNames">The role names.</param>
public RequiresRoleAttribute(params string[] roleNames) {
this.requiredRoles = new List<string>(roleNames);
}
/// <summary>
/// Called by the MVC framework before the action method executes.
/// </summary>
/// <param name="filterContext">The filter context.</param>
public override void OnActionExecuting(ActionExecutingContext filterContext) {
bool hasRole = false;
// check to see if the user has the proper role here
// if the do not have the role, they are not allowed to execute the action
if (!hasRole)
throw new UserAccessException("You do not have access to this action (" + filterContext.ActionDescriptor.ActionName + ", " + filterContext.ActionDescriptor.ControllerDescriptor.ControllerName + ")");
base.OnActionExecuting(filterContext);
}
}
Second to solve your problem of no logic in the views you could use child actions for each section which requires a role. Again you could apply your filter to the child actions. For more on child actions see: http://msdn.microsoft.com/en-us/library/ie/ee839451.aspx.
What you would need to change is the section that throws the exception. You'd need to check to see if the action being executed is a child action. If so, you'd want to return an empty content result.
Currently I'm using this code to create a custom filter:
var fName = new FilterDescriptor
{
Member = "Name",
MemberType = typeof(string),
Operator = FilterOperator.Contains,
Value = name
};
Which will be added to the GridCommand like this:
gridCommand.FilterDescriptors.Add(fName);
However, would like to create filters based on Linq lambda expression like:
IQueryable<CD> query = ...
if (!string.IsNullOrWhiteSpace(Artist))
{
query = query.Where(cd => cd.Artist.Contains(Artist));
}
if (!string.IsNullOrWhiteSpace(Name))
{
query = query.Where(cd => cd.Name.Contains(Name));
}
How to do this ?
In the QueryableExtensions.cs file from Telerik, this extension method will do the job:
/// <summary>
/// Filters a sequence of values based on a collection of <see cref="IFilterDescriptor"/>.
/// </summary>
/// <param name="source">The source.</param>
/// <param name="filterDescriptors">The filter descriptors.</param>
/// <returns>
/// An <see cref="IQueryable" /> that contains elements from the input sequence
/// that satisfy the conditions specified by each filter descriptor in <paramref name="filterDescriptors" />.
/// </returns>
public static IQueryable Where(this IQueryable source, IEnumerable<IFilterDescriptor> filterDescriptors) { }
Ok so there isnt much wrong with the way you are doing it currently. Except if you were determined to add as linq expression then use the following example.
var query = from t in query where t.Artist.Contains(Artist) && t.Name.Contains(Name) select t;
If both Artist and Name are empty or null then it will return all anyway.
I have had a problem where it appeared as though the second execution of a stored procedure was being ignored.
The first time I call my stored procedure it found 20 records and extracted information for the date range August 2009. The first line was meter id 233 with a data value 200
I then called the stored procedure and 20 records were also returned. This time meter id 233 had a data value of 300.
Linq is detecting that meterid 233 already exists in the context and so doesnt update
I am sure this is something to do with ObjectTrackingEnabled but this does not seem to be available for me to set to false?
I didnt write the context code so I dont really know how it all works, but I have noticed that it seems to inherit from ObjectDataContext
This was generate using Entity Framework and VS 2008
namespace DataServiceDAL
{
/// <summary>
/// There are no comments for dbChildDataContext in the schema.
/// </summary>
public partial class dbChildDataContext : global::System.Data.Objects.ObjectContext
{
/// <summary>
/// Initializes a new dbChildDataContext object using the connection string found in the 'dbChildDataContext' section of the application configuration file.
/// </summary>
public dbChildDataContext() :
base("name=dbChildDataContext", "dbChildDataContext")
{
this.OnContextCreated();
}
/// <summary>
/// Initialize a new dbChildDataContext object.
/// </summary>
public dbChildDataContext(string connectionString) :
base(connectionString, "dbChildDataContext")
{
this.OnContextCreated();
}
/// <summary>
/// Initialize a new dbChildDataContext object.
/// </summary>
public dbChildDataContext(global::System.Data.EntityClient.EntityConnection connection) :
base(connection, "dbChildDataContext")
{
this.OnContextCreated();
}
partial void OnContextCreated();
..............
}
I use the following linq to extract the data
public static List<MeterTotalConsumpRecord> GetTotalAllTimesConsumption(DateTime dtStart, DateTime dtEnd, EUtilityGroup ug, int nMeterSelectionType, int nCustomerID,
int nUserID, string strSelection, bool bClosedLocations, bool bDisposedLocations)
{
dbChildDataContext db = DBManager.ChildDataConext(nCustomerID);
var tbl = from t in db.GetTotalConsumptionByMeter(dtStart, dtEnd, (int) ug, nMeterSelectionType, nCustomerID, nUserID, strSelection, bClosedLocations, bDisposedLocations, 1)
select t;
return tbl.ToList();
}
I need a way of clearing this cache out so that the objects are updated properly or I need a way of refreshing the objects
Can anyone help?
Cheers
Paul
We recommend you to refresh objects using MergeOption.
Here is a simple example:
var query = from d in context.Depts
where d.Deptno < 50
select d;
(query as ObjectQuery).MergeOption = MergeOption.OverwriteChanges;
