【问题描述】:
我正在使用ObservableCollection 在我的WPF 应用程序中生成一个列表。
public partial class NameList : ObservableCollection<SetCredentialsForAD>
{
public NameList() : base()
{
using var forest = Forest.GetCurrentForest();
Forest currentForest = Forest.GetCurrentForest();
DomainCollection domains = currentForest.Domains;
foreach (Domain objDomain in domains)
{
Add(new SetCredentialsForAD("domain", "name", "password"));
}
}
}
public class SetCredentialsForAD
{
private string loginName;
private string passWord;
private string domainName;
public SetCredentialsForAD(string domain, string lName, string pWord)
{
this.domainName = domain;
this.loginName = lName;
this.passWord = pWord;
}
public string DomaineName
{
get { return domainName; }
set { domainName = value; }
}
public string LoginName
{
get { return loginName; }
set { loginName = value; }
}
public string PassWord
{
get { return passWord; }
set { passWord = value; }
}
}
Xaml:
<ListBox x:Name="CredentialList" Width="auto" Height="auto"
Grid.Column="0" Grid.Row="2" Style="{StaticResource CredentialList}"
SelectionMode="Multiple"
ItemsSource="{Binding Source={StaticResource NameListData}}"
ItemTemplate="{StaticResource NameItemTemplate}"
IsSynchronizedWithCurrentItem="True"/>
xaml 数据模板:
<c:NameList x:Key="NameListData"/>
<DataTemplate x:Key="NameItemTemplate">
<Grid>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<TextBlock x:Name="DomainNameForCredentials" FontSize="18" Grid.Row="2" Grid.Column="0" Text="{Binding Path=DomaineName, Mode=TwoWay}" Style="{StaticResource CredentialListTextBlock}" ></TextBlock>
<Label Grid.Row="1" Grid.Column="1" Content="samAccountName" Style="{StaticResource CredentialListLabel}" ></Label>
<Label Grid.Row="1" Grid.Column="2" Content="Passwort" Style="{StaticResource CredentialListLabel}"></Label>
<TextBox x:Name="samAccountNameForCredentials" Grid.Row="2" Grid.Column="1" Text="{Binding Path=LoginName, Mode=TwoWay}" Style="{StaticResource CredentialListTextBox}" />
<TextBox x:Name="passwordForCredentials" Grid.Row="2" Grid.Column="2" Text="{Binding Path=PassWord, Mode=TwoWay}" Style="{StaticResource CredentialListTextBox}"/>
</Grid>
</DataTemplate>
我需要在单击列表中添加一个新项目以在我的 UI 中显示它并用它做其他事情。
我尝试了一些添加空列表项的方法,例如:
var setCredentialsforAD = new NameList();
setCredentialsforAD.Add(new SetCredentialsForAD("","",""));
解决我的问题的正确方法是什么?
谢谢

您没有描述任何问题。 UI 中的列表是否仍为空白?当您使用调试器查看项目时,是否不会在代码中添加项目?你设置了DataContext吗?帮助我们帮助您。
