爲什麼我的DataGridTemplateColumn和RadioButton在我的DataGrid中不可見？

Question

爲什麼我在DataGrid中看不到RadioButton的列？

<DataGrid x:Name="dg" Visibility="Visible" Margin="0,191,0,374" Width="1000" HeadersVisibility="Column" SelectionUnit="Cell" CanUserAddRows="False" AutoGenerateColumns="False" HorizontalAlignment="Left" Grid.ColumnSpan="2" Grid.RowSpan="2"> 
    <DataGridTemplateColumn Width="85" Header="Kurs"> 
     <DataGridTemplateColumn.CellTemplate> 
      <DataTemplate> 
       <RadioButton GroupName="DataGridChkBoxes" IsChecked="{Binding IsPresent2}" x:Name="rb" Content="rb" Width="50"/> 
      </DataTemplate> 
     </DataGridTemplateColumn.CellTemplate> 
    </DataGridTemplateColumn> 

    <DataGrid.Columns> 
     <DataGridTextColumn Binding="{Binding Nazwa}" Header="Nazwa" Width="300" IsReadOnly="True"/> 
     <DataGridTextColumn Binding="{Binding KursZdarzenia}" Header="Kurs" IsReadOnly="True"/> 
    </DataGrid.Columns> 
</DataGrid> 

Answer 1

您的DataGridTemplateColumn不在DataGrid.Columns區塊內。

嘗試中移動它：

<DataGrid ...> 
    <DataGrid.Columns> 
     <DataGridTemplateColumn Width="85" Header="Kurs"> 
      <DataGridTemplateColumn.CellTemplate> 
       <DataTemplate> 
        <RadioButton GroupName="DataGridChkBoxes" IsChecked="{Binding IsPresent2}" x:Name="rb" Content="rb" Width="50"/> 
       </DataTemplate> 
      </DataGridTemplateColumn.CellTemplate> 
     </DataGridTemplateColumn> 

     <DataGridTextColumn Binding="{Binding Nazwa}" Header="Nazwa" Width="300" IsReadOnly="True"/> 
     <DataGridTextColumn Binding="{Binding KursZdarzenia}" Header="Kurs" IsReadOnly="True"/> 
    </DataGrid.Columns> 
</DataGrid>
