我正在尝试使用Label控件在XAML中显示一个字符串.以下是我的XAML代码:

<Label Height="28" HorizontalAlignment="Left" Margin="233,68,0,0" Name="label13" VerticalAlignment="Top">
    <Label.Content>
        <MultiBinding StringFormat="{}{0} x {1}">
              <Binding Path="Width" />
              <Binding Path="Height" />
        </MultiBinding>
    </Label.Content>

宽度和高度是我的类Movie的两个属性.我希望标签显示:"宽度x高度"ex.800 x 640但标签控件仍为空.任何帮助表示赞赏.我想在不使用转换器的情况下做这件事.

我使用TextBlock而不是Label修改了我的xaml.但它仍然不会填充显示输出.

<TextBlock Height="28" HorizontalAlignment="Left" Margin="233,68,0,0" Name="label13" VerticalAlignment="Top">
                <TextBlock.Text>
                    <MultiBinding StringFormat="{}{0} x {1}">
                        <Binding Path="Width" />
                        <Binding Path="Height" />
                    </MultiBinding>
                </TextBlock.Text>
            </TextBlock>

我有以下XAML.如何突出显示ItemsControl中的所选项？我可以覆盖ListView的选定项目模板,但如何为ItemsControl实现相同的功能？有没有可以显示图像集的替代控件？

<Window x:Class="ImageScrollDemo.View.MoviePosterView"

我有以下类结构:

public class PriceLog
{
   public DateTime LogDateTime {get; set;}
   public int Price {get; set;}
}

对于List <PriceLog>,我希望Linq查询生成一个输出,该输出等效于如下所示的数据:

LogDateTime | AVG(价格)
2012年1月| 2000年
2月2012 | 3000

简单地说:我想计算一年中每个月的平均价格.
注意:LogDateTime属性应格式化为LogDateTime.ToString("MMM yyyy")

我尝试了以下内容,但不确定它是否会产生所需的结果:

var result = from priceLog in PriceLogList
                         group priceLog by priceLog.LogDateTime.ToString("MMM yyyy") into dateGroup
                         select new PriceLog { GoldPrice = (int)dateGroup.Average(p => p.GoldPrice), SilverPrice = (int)dateGroup.Average(p => p.SilverPrice)};

我正在尝试根据以下模型对我的集合进行分组:

public class Person
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public Role PersonRole { get; set; }
}

public class Role
{
    public int Id { get; set; }
    public string RoleName { get; set; }
}

我的PersonCollection,

public ObservableCollection<Person> PersonList;

该集合中填充了三个Person对象,两个具有相同的角色.

我想按照他们的角色名称对所有人进行分组.我有以下XAML:

<Grid.Resources>

        <CollectionViewSource x:Key="cvs" Source="{Binding PersonList}">
            <CollectionViewSource.GroupDescriptions>
                <PropertyGroupDescription PropertyName="PersonRole.RoleName"/>
            </CollectionViewSource.GroupDescriptions>
        </CollectionViewSource>

    </Grid.Resources>

<ListBox ItemsSource="{Binding Source={StaticResource cvs}}">
        <ListBox.ItemTemplate>
            <DataTemplate>
                <TextBlock Text="{Binding FirstName}"/>
            </DataTemplate>
        </ListBox.ItemTemplate>
        <ListBox.GroupStyle>
            <GroupStyle>
                <GroupStyle.HeaderTemplate>
                    <DataTemplate>
                        <TextBlock Text="{Binding …

我有一个列表列表对象:

List<List<Movie>> MovieList

该MovieList对象是电影列表的集合,每个电影列表基于特定的电影类型.恩.MovieList[0]将是喜剧类型的电影列表,依此类推现在我想将这个列表列表MovieList对象绑定到XAML中的ListView.ListView ItemSource将绑定到此MovieList对象,此ListView的每个ListViewItem将是一个ListView本身,绑定到特定类型的电影列表.恩.喜剧类型电影列表.此外,此内部List的每个ListViewItem都将绑定到该特定影片的Title属性.请帮我设计XAML代码.

我正在尝试为项目控件中的每个项目设置边框.以下是我的XAML代码.但这不起作用.

<ItemsControl.ItemContainerStyle>
    <Style>
        <Setter Property="Control.BorderThickness" Value="5" />
        <Setter Property="Control.BorderBrush" Value="Black" />
    </Style>
</ItemsControl.ItemContainerStyle>

我在MVVM中为WPF DataGrid实现了CollectionViewSource的小型演示.我非常感谢任何帮助来验证实现并评论这是否是使用CollectionViewSource的正确方法.

public class ViewModel : NotifyProperyChangedBase
{       
    private ObservableCollection<Movie> _movieList;
    public ObservableCollection<Movie> MovieList
    {
        get { return _movieList; }
        set
        {
            if (this.CheckPropertyChanged<ObservableCollection<Movie>>("MovieList", ref _movieList, ref value))
                this.DisplayNameChanged();
        }
    }

    private CollectionView _movieView;
    public CollectionView MovieView
    {
        get { return _movieView; }
        set
        {
            if (this.CheckPropertyChanged<CollectionView>("MovieView", ref _movieView, ref value))
                this.DisplayNameChanged();
        }
    }

    public ViewModel()
    {
          MovieView = GetMovieCollectionView(MovieList);
    }

    private void DisplayNameChanged()
    {
        this.FirePropertyChanged("DisplayName");
    }

    public void UpdateDataGrid(string uri)
    {            
        MovieView = GetMovieCollectionView(new ObservableCollection<Movie>(MovieList.Where(mov => uri.Contains(mov.ID.ToString())).ToList<Movie>()));
    }

我的角度页面有以下Kendo UI gridOptions:

ctrl.gridOptions = {
        rowTemplate: '<tr data-uid="#: uid #" class="#:ApprovalStatus=\'Approved\'? \"approved\" : \"unapporved\"#"></tr>',
        //rowTemplate: '<tr data-uid="#: uid #" class="#:ApprovalStatus=\'Approved\' ? \'approved\' : \'unapproved\' #"><td>#:ProcessName #</td><td>#:TradeAmount #</td><td>#:AQRID #</td><td>#:ApprovalStatus #</td></tr>',

                    }, function (response) {
                        alert('something went wrong')

我有以下用于WPF ListBox控件的xaml.我已经定制了它以满足我的UI要求.但是,滚动条滑块不会到达滚动条的顶部和底部.如果我点击垂直滚动条轨道上的其他位置,拇指也不会滚动.请帮我解决问题.任何帮助表示赞赏.

我想删除在上面的datagridcell中可以看到的Romance周围的虚线边框.每当我使用键盘左右导航键时,就会出现边框.我怎么能摆脱它？
