Question

我有这个Xaml，它在DataGrid中生成一列按钮。问题是图像不显示！我怎么解决这个问题？

<DataGrid.Columns>
    <DataGridTextColumn Header="Description" Binding="{Binding Description}" Width="*" />
    <DataGridTextColumn Header="Output" Binding="{Binding Output}" Width="*"/>
    <DataGridTextColumn Header="Input" Binding="{Binding Input}" Width="*" />
    <DataGridTemplateColumn>
        <DataGridTemplateColumn.CellTemplate>
            <DataTemplate>
                <Button Click="Add_Button_Click" Visibility="Visible" Height="16" Width="16">
                    <Image Height="16" Source="/Resources/plus.png" Stretch="Fill" Width="16"/>
                </Button>
            </DataTemplate>
        </DataGridTemplateColumn.CellTemplate>
    </DataGridTemplateColumn>
</DataGrid.Columns>

Answer 1

添加按钮内容并将图像放入Button.Content

<Button >
  <Button.Content>
     <Image x:Name="KeyName"  Source="pack://Resources/image.png"  />
  </Button.Content>
</Button>
