在数据网格中显示子集合 [英] Display a sub collection in a datagrid

问题描述

我有一些招聘人员，每个招聘人员都有一组电子邮件地址。



我可以选择电子邮件地址，并将它们放入如下集合中： br $> b $ b

I have a collection of recruiters, and each recruiter has a collection of email addresses.

I can select the emailadresses and put them in a collection like:

var query =来自_container中的e。 EmailAddresses选择e

this.EmailAddresses = new DataServiceCollection< emailaddresses>（查询）。







当我进行这样的用户控制时

var query = from e in _container.EmailAddresses select e
this.EmailAddresses = new DataServiceCollection<emailaddresses>(query).



When I make an usercontrol like this

<UserControl>
<DataGrid ItemsSource="{Binding Path=Recruiters"}>
<DataGrid.Columns>
<DataGridTemplateColumn>
<DataGridTemplateColumn.CellTemplate>
<ItemsControl ItemsSource="{Binding DataContext.EmailAddresses, RelativeSource={RelativeSource AncestorType=UserControl}}>
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<Stackpanel Orientation="Vertical"/>
</ItemsPanelTemplate>
<ItemsControl.ItemTemplate>
<DataTemplate>
<TextBox Text = "{Binding Address"}/>
</DataTemplate>
</ItemtsControl.ItemTemplate>
</ItemsControl>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
</DataGrid.Columns>
</DataGrid>
</UserControl>

我每行上都一样电子邮件地址，我理解。



我可以通过各自的电子邮件获得招聘人员的集合，例如

I get on each row the same email addresses, which I understand.

I can get the collection of recruiters with their respective emailaddresses like

var query = from r in _container.Recruiters.Expand(r => r.EmailAddresses) select r

this.Recruiters = new DataServiceCollection<Recruiters>(query).

我必须将usercontrol绑定到Recruiters.EamilAddresses，但这不起作用。



任何想法如何实现这一目标？



基本上我想在每一行上显示一个子集。



亲切的问候



Jeroen

I would have to bind the usercontrol to Recruiters.EamilAddresses, but that doesn't work.

Any ideas how to accomplish this?

Basically I would like to display a subcollection on each row.

Kind regards

Jeroen

推荐答案

想出来。



将xaml更改为

Figured it out.

Change the xaml to

<usercontrol>
<usercontrol.resources>
<datatemplate x:key="EamilAddresses" datatype="{x:Type something:Recruiters}" xmlns:x="#unknown">
<stackpanel orientatien="Vertical">
<textbox text="{Binding" hold=" /></StackPanel><br mode=" path="Recruiters"}">
<datagrid.columns>
<datagridtemplatecolumn>
<datagridtemplatecolumn.celltemplate>
<datatemplate>
<itemscontrol itemssource="{Binding EmailAddresses}<br mode=" hold=" />ItemTemplate="></itemscontrol></datatemplate></datagridtemplatecolumn.celltemplate></datagridtemplatecolumn></datagrid.columns></textbox></stackpanel></datatemplate></usercontrol.resources></usercontrol>

<usercontrol>
<usercontrol.resources>
<datatemplate x:key="EamilAddresses" datatype="{x:Type something:Recruiters}" xmlns:x="#unknown">
<stackpanel orientatien="Vertical">
<textbox text="{Binding" hold=" /></StackPanel><br mode=" path="Recruiters"}">
<datagrid.columns>
<datagridtemplatecolumn>
<datagridtemplatecolumn.celltemplate>
<datatemplate>
<itemscontrol itemssource="{Binding EmailAddresses}<br mode=" hold=" />ItemTemplate="></itemscontrol></datatemplate></datagridtemplatecolumn.celltemplate></datagridtemplatecolumn></datagrid.columns></textbox></stackpanel></datatemplate></usercontrol.resources></usercontrol>
