所以我现在有一些硬编码的数据，但打算查询SQL数据库以填充一些字段。
我想根据需要使用ContactExpander UserControls填充此StackPanel：
<ScrollViewer Height="350" VerticalScrollBarVisibility="Auto" CanContentScroll="True">
<DockPanel>
<StackPanel Name="ContactStackPanel" Margin ="16">
<!-- Autopopulate the usercontrols here -->
</StackPanel>
</DockPanel>
</ScrollViewer>
ContactViewModel如下：
namespace Outreach_Alpha2
{
class ContactViewModel : ViewModelBase
{
//Declare contact variables
private string _title;
private string _firstName;
private string _middleInitial;
private string _lastName;
private string _position;
private string _email;
private string _phoneNumber;
private string _phoneExtension;
private string _faxNumber;
public string ContactHeader { get; set; }
public ObservableCollection<string> TitleSource { get; set; }
//First Name
//Set regex
public string Title
{
get { return _title; }
set
{
if (_title != value)
{
Validator.ValidateProperty(value, new ValidationContext(this, null, null) { MemberName = "Title" });
_title = value;
OnPropertyChanged("Title");
}
}
}
//First Name
[Required(AllowEmptyStrings = false)]
[RegularExpression(@"\b^[A-Z][a-zA-Z '&-]*[A-Za-z]$\b", ErrorMessage = @"Invalid First Name.")]
public string FirstName
{
get { return _firstName; }
set
{
if (_firstName != value)
{
Validator.ValidateProperty(value, new ValidationContext(this, null, null) { MemberName = "FirstName" });
_firstName = value;
OnPropertyChanged("FirstName");
}
}
}
//MiddleInitial
//Set regex
public string MiddleInitial
{
get { return _middleInitial; }
set
{
if (_middleInitial != value)
{
Validator.ValidateProperty(value, new ValidationContext(this, null, null) { MemberName = "MiddleInitial" });
_middleInitial = value;
OnPropertyChanged("MiddleInitial");
}
}
}
//Last Name
[Required(AllowEmptyStrings = false)]
[RegularExpression(@"\b^[A-Z][a-zA-Z '&-]*[A-Za-z]$\b", ErrorMessage = @"Invalid last name.")]
public string LastName
{
get { return _lastName; }
set
{
if (_lastName != value)
{
Validator.ValidateProperty(value, new ValidationContext(this, null, null) { MemberName = "LastName" });
_lastName = value;
OnPropertyChanged("LastName");
}
}
}
//Position
//Set regex
public string Position
{
get { return _position; }
set
{
if (_position != value)
{
Validator.ValidateProperty(value, new ValidationContext(this, null, null) { MemberName = "Position" });
_position = value;
OnPropertyChanged("Position");
}
}
}
//Email
//Set regex
public string Email
{
get { return _email; }
set
{
if (_email != value)
{
Validator.ValidateProperty(value, new ValidationContext(this, null, null) { MemberName = "Email" });
_email = value;
OnPropertyChanged("Email");
}
}
}
//Phone Number
//Set regex
public string PhoneNumber
{
get { return _phoneNumber; }
set
{
if (_phoneNumber != value)
{
Validator.ValidateProperty(value, new ValidationContext(this, null, null) { MemberName = "PhoneNumber" });
_phoneNumber = value;
OnPropertyChanged("PhoneNumber");
}
}
}
//Phone Extension
//Set regex
public string PhoneExtension
{
get { return _phoneExtension; }
set
{
if (_phoneExtension != value)
{
Validator.ValidateProperty(value, new ValidationContext(this, null, null) { MemberName = "PhoneExtension" });
_phoneExtension = value;
OnPropertyChanged("PhoneExtension");
}
}
}
//Fax Number
//Set regex
public string FaxNumber
{
get { return _faxNumber; }
set
{
if (_faxNumber != value)
{
Validator.ValidateProperty(value, new ValidationContext(this, null, null) { MemberName = "FaxNumber" });
_faxNumber = value;
OnPropertyChanged("FaxNumber");
}
}
}
}
}
ContactExpander UserControl模板如下：

</UserControl>
这是ContactExpander UserControl的代码隐藏：
namespace Outreach_Alpha2
{
/// <summary>
/// Interaction logic for ContactExpander.xaml
/// </summary>
public partial class ContactExpander : UserControl
{
public ContactExpander()
{
InitializeComponent();
this.DataContext = new ContactViewModel();
}
}
}
我有一个包含以下内容的自定义结构：
public class ContactInfo
{
public String FirstName { get; set; }
public String MiddleInitial { get; set; }
public String LastName { get; set; }
public String Title { get; set; }
public String Position { get; set; }
public long PhoneNumber { get; set; }
public int PhoneExtension { get; set; }
public long FaxNumber { get; set; }
public String Email { get; set; }
public String CurrentUser { get; set; }
}
我填充这些字段：
var contactList = new List<ContactInfo>()
{
new ContactInfo(){ FirstName = "John", MiddleInitial = "", LastName = "Doe", Title = "Dr.", Position = "CEO", PhoneNumber = 8005551234, PhoneExtension = 1234, FaxNumber = 3615559876, Email = "john.doe@abc.com", CurrentUser = ""},
new ContactInfo(){ FirstName = "Jane", MiddleInitial = "", LastName = "Doe", Title = "Mrs.", Position = "", PhoneNumber = 8005551235, PhoneExtension = 1234, Email = "jane.doe@abc.com", CurrentUser = ""},
};
我只是不知道从哪里开始。我不知道如何使用绑定到ViewModel的自动填充ContactExpander UserControl，我不知道如何使用自动填充的ContactExpanders自动填充Stackpanel。
