我有下一个boostrap单选按钮:

<div class="btn-group" id="filterDay" data-toggle="buttons">
       <label class="btn btn-default blue">
         <input type="radio" class="toggle" value="1">Monday
       </label>
       <label class="btn btn-default blue">
         <input type="radio" class="toggle" value="2"> Tuesday
       </label>
       <label class="btn btn-default blue">
         <input type="radio" class="toggle" value="3"> Wednesday
       </label>
       <label class="btn btn-default blue">
         <input type="radio" class="toggle" value="4"> Thursday
       </label>
       <label class="btn btn-default blue">
          <input type="radio" class="toggle" value="5"> Friday
       </label>
       <label class="btn btn-default blue">
           <input type="radio" class="toggle" value="6"> Saturday
        </label>
       <label class="btn btn-default blue active">
           <input type="radio" class="toggle" value="0"> Sunday
       </label>
</div>

我在提交表单时尝试获取活动按钮的值,而不创建"onclick"事件,只需从$('#filterDay')按钮组获取活动按钮.应该很容易,但我找不到获得价值的方法.我尝试了几个例子但是有效.

有人可以帮忙吗？

谢谢!

我正在尝试实现我的第一个MVVM应用程序.我可以将数据绑定到数据网格中,但是我在项目中所做的更改不会触发模型的RaisePropertyChanged方法.

这是我的ViewModel

    public class UsersViewModel : BaseViewModel
{
    private static TOPEntities _context;
    private ObservableCollection<UserModel> _usersCollection;

           public UsersViewModel()
    {
        _usersCollection = new ObservableCollection<UserModel>(GetAllUsers());

    }
          public ObservableCollection<UserModel> UsersCollection
    {
        get { return _usersCollection; }
        set
        {
            if (_usersCollection != value)
            {
                _usersCollection = value;
                RaisePropertyChanged(() => UsersCollection);
            }
        }
    }
public static List<UserModel> GetAllUsers()
    {
        using (_context = new TOPEntities())
        {

            return _context.Users.Select
             (user => new UserModel
             {
                 Id_User = user.Id_User,
                 Name = user.Name,
                 Username = user.Username,
                 Language = user.Language,
                 Password = …

当我按下按钮时,我正试图获得两个Texbox的值(我正在模拟一个登录窗口).按钮中指定的命令正确触发,但我不知道如何获取文本框的值来执行"登录".

这是我的ViewModel:

class LoginViewModel : BaseViewModel
{   
    public LoginViewModel()
    {

    }

    private DelegateCommand loginCommand;
    public ICommand LoginCommand
    {
        get
        {
            if (loginCommand == null)
                loginCommand = new DelegateCommand(new Action(LoginExecuted),
                               new Func<bool>(LoginCanExecute));
                return loginCommand;
            }
        } 

    public bool LoginCanExecute()
    {
        //Basic strings validation...
        return true;
    }
    public void LoginExecuted()
    {
        //Do the validation with the Database.
        System.Windows.MessageBox.Show("OK");
    } 
}

这是观点:

 <Grid DataContext="{StaticResource LoginViewModel}">

            <TextBox x:Name="LoginTxtBox" HorizontalAlignment="Left" Height="23" Margin="34,62,0,0" Width="154" />
            <PasswordBox x:Name="PasswordTxtBox" HorizontalAlignment="Left" Height="23" Margin="34,104,0,0" Width="154"/>
            <Button x:Name="btnAccept"
            HorizontalAlignment="Left" 
            Margin="34,153,0,0" 
            Width="108" …
