WPF - 将字符串列表绑定到数据网格中的列 [英] WPF - Binding a list of a string to a column in Data Grid

问题描述

我有一个包含三列的数据网格.

I have a datagrid with three columns.

 <DataGrid IemSource={Binding SomeData}>
       <DataGrid.Columns>
           <DataGridTemplateColumn>

           </DataGridTemplateColumn>

          <DataGridTemplateColumn>

          </DataGridTemplateColumn>

          <DataGridTemplateColumn>
             <DataGridTemplateColumn.HeaderTemplate>
                <DataTemplate>
                   <ItemsControl ItemSource="{Binding SomeList}">
                     <StackPanel Orientation="Horizontal">
                       <TextBlock Text="SomeTopic"/>
                       <ComboBox ItemSource="{Binding }"/>
                    </StackPanel>
                  </ItemsControl>
               </DataTemplate>
            </DataGridTemplateColumn.HeaderTemplate>
         <DataGridTemplateColumn.CellTemplate>
             <DataTemplate>
                 <ComboBox  />
            </DataTemplate>
       </DataGridTemplateColumn.CellTemplate>
    </DataGridTemplateColumn>


    </DataGrid.Columns>

SomeData 是 ClassA 的对象集合.A 类包含两个字符串字段，我已将它们绑定到前 2 列.

SomeData is a object collection of ClassA. Class A contains two string fields and I have binded them to the first 2 columns.

该类包含名称为 SomeList 的字符串变量列表.我已将其绑定到第 3 列.我需要将它附加到第 3 列标题中的组合框.但是这段代码没有给我我想要的.

The class contains a List of string variables of which the name is SomeList. I have binded it to the 3rd column. I need to attach it to the combobox in the header of column 3. But this code does not give me what I want.

有人可以帮忙吗?

推荐答案

您的问题似乎是您将 StackPanel 作为项目添加到 ItemsControl 而不是在 DataTemplate 中使用它.

Your problem seems to be that you add the StackPanel as item to the ItemsControl instead of using it in a DataTemplate.

代替

<ItemsControl ItemSource="{Binding SomeList}">
    <StackPanel Orientation="Horizontal">
        <TextBlock Text="SomeTopic"/>
        <ComboBox ItemSource="{Binding }"/>
    </StackPanel>
</ItemsControl>

它应该是这样的:

<ItemsControl ItemSource="{Binding SomeList}">
    <ItemsControl.ItemTemplate>
        <DataTemplate>
            <StackPanel Orientation="Horizontal">
                <TextBlock Text="SomeTopic"/>
                <ComboBox ItemSource="{Binding }"/>
            </StackPanel>
        </DataTemplate>
    </ItemsControl.ItemTemplate>
</ItemsControl>
