将模型值绑定到datagrid [英] Bind model values to datagrid

问题描述

我有一个小问题，我有一个模型（基本上在视图模型中它将是模型列表）

I have a small question, I have a model (well basically in view model it will be list of models)

public class FlagAnalysis
{
    public DateTime DailyTimestampInterval { get; set; } = DateTime.UtcNow;

    public int[] Flags { get; set; } = {};
}

在视图模型中：

 public ObservableCollection<FlagAnalysis> FlagValues { get; set; } = new ObservableCollection<FlagAnalysis>()

因为你看到我有一个带有Datetime和int集合的模型集合，现在我想基于此构建一个datagrig，所以它看起来像：

So as you see I have a collection of model with a Datetime and a collection of int, Now i want to build a datagrig based on this so it would look like:

  02.03.2018 | 03.03.2018 | 04.03.2018
  --------------------------------------
       1     |      0     |     3
       2     |      2     |     1

对于每个DailyTimestampInterval作为标题标题，我想要一个包含标志集合值的collumn ，

For every DailyTimestampInterval as a header title, i want a collumn that contains flags collection value,

现在我的xaml看起来像

for now my xaml looks like

<DataGrid ItemsSource="{Binding FlagValues}" AutoGenerateColumns="False" >

< DataGrid.Resources > < businessLogic ： BindingProxy   x ： 键 = &qu ot;代理"  数据 =" { 绑定 } "   />

<DataGrid.Resources> <businessLogic:BindingProxy x:Key="proxy" Data="{Binding}" />

< / DataGrid.Resources > < DataGrid.Columns >

< DataGridTemplateColumn  标题 =" { 装订  数据 。 时间戳 ，  来源 = { StaticResource   proxy }} "   />

<DataGridTemplateColumn Header="{Binding Data.Timestamps, Source={StaticResource proxy}}" />

< / DataGrid.Columns < span style ="color：blue">>

< / DataGrid >

sutch是否可能

推荐答案

嗨  WojszaM，

Hi  WojszaM,

也就是说，假设有多个项目在FlagAnalysis中，此数据网格中有多少列？

这不是DataGrid应该做的。

That is not DataGrid should do .

< span class ="x_x_short_text"id ="x_x_result_box"lang ="en"tabindex =" - 1"> 改用ListBox或ItemControl，覆盖
ItemsPanel 进行安排这几项。定义datatemplate以显示Item。

Use ListBox or ItemControl instead, override the ItemsPanel to arrange the items. Define the datatemplate to display Item.

    <ListBox
                    Height="300"
                    Margin="10"
                    ItemsSource="{Binding observableCollection, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type Window}}}">
                    <ListBox.ItemsPanel>
                        <ItemsPanelTemplate>
                            <VirtualizingStackPanel Orientation="Horizontal" />
                        </ItemsPanelTemplate>
                    </ListBox.ItemsPanel>
                    <ListBox.ItemTemplate>
                        <DataTemplate>
                            <Grid >
                                <Grid.RowDefinitions>
                                    <RowDefinition  />
                                    <RowDefinition />
                                </Grid.RowDefinitions>

                            </Grid>
                        </DataTemplate>
                    </ListBox.ItemTemplate>
                </ListBox>
