Drag and Drop data binding and Enums

  
I'm using Visual Studio 2010 to design a simple WPF application. I created a simple class, with some Enum property, and added the class as a new data source, then dragged and dropped it from the Data sources window as a DataGrid. The result is a data grid that works properly, except for enum handling. Obviously, I want enums to be displayed as combo boxes, so I set the option. The problem is: I get a combo box column, but it is NOT populated with the Enum's values, instead only the current value is displayed and the user can't change it. This behavior seems completely useless to me. Am I doing something wrong here, or is there another explanation for this? Why isn't the designer handling enums in a sensible way? Another problem is, if I choose to drag the class as "Details". Again everything works except enums. I get a standalone combobox, but it displays the values of the property from the entire list, and choosing a different item in the combobox changes the active bound property. Once again, useless behavior - I expect the designer to create a combobox populated with values from the Enum, and for it to act like every other control in a master-details relationship - choosing a different value changes the state of the current item. Please advise.

Data Binding a DataGrid to a list fetch the same data multiple times

  
Hi, I'm using DataGrid to show data through data binding. My data are provided in a list. The setup I have is the following: DataGrid "binded" to the default view of my list that implement IList<T> and IList interfaces (MyList<T> : IList<T>, IList, INotifyCollectionChanged)             CollectionViewSource.GetDefaultView(_myList);             // Set the data context             DataContext = view; T: is here my 'business object' that hold the data, called 'MyRow'. Then the columns of the DataGrid are bound to public properties of 'MyRow' object. MyRow class has a public property of type 'object' (public object data[int index]) and first column of datagrid is bound to myRow.data[0], second column is bound to myRow.data[1] and so on.   When the datagrid is displayed, databinding kick in and my data are showed in the control. The issue I'm having is that data fetching is very repetitive even for the same rows. For example for a datagrid with 20 visible rows, the first row is fetched multiple times even if the datagrid is not resized or moved. I put break point inside my list (MyList<T> into This[T] property (public T this[int index]) and i got multiple hits into the property for the same index. Fetc

Binding list to form not working with '&' character in list field data

  
Hi, I have a SharePoint list with a field called Title. I have a form based on this list with the field bound to the form as a label (for workflow to access). Here is the code for the form field. <asp:Label runat="server" id="ff2{$Pos}" text="{@Title}" __designer:bind="{ddwrt:DataBind('u',concat('ff2',$Pos),'Text','','ID',ddwrt:EscapeDelims(string(@ID)),'@Title')}" /> I have a workflow that runs through a form action button which take ff2 (title) and  does other stuff. The problem I have is with records where the value of 'title' contains the '&' character (example ab&cd). Blank is pulled in by the workflow when I get the value of ff2. I am guessing it has to do with the data binding and/or escape (special) characters coming through but I don't know how to fix it. Any help will be greatly appreciated

Populate Drop-Down list box from Active Directory Data Connection?

  
Hi,

I recently created a data connection to my active directory, so that certain fields can be automatically populated given the user who is filling in the form.

However, I would like to have a drop-down box that is populated from Active Directory (i.e. the user of the form can select another AD member), the result of which will then populate other fields (with information such as Manager, Email Address, etc).

So, 2 questions:

  1. How do I get a drop-down list to populate with the members of AD?
  2. How do I get the result of this selection to populate other fields?
Cheers again - you guys are great!
