以下 xaml 代码将“图像”与 datagrid 模板列绑定。

     <DataGridTemplateColumn Header="">

       <DataGridTemplateColumn.CellTemplate>

           <DataTemplate>

                <Image Source="{Binding Path=Image}" Height="16" Width="16" VerticalAlignment="Top" />

             </DataTemplate>
        </DataGridTemplateColumn.CellTemplate>

   The same thing need to be done in codebehind (c# code)  

       DataGridTemplateColumn im = new DataGridTemplateColumn();
       im.Header = "";
       Binding items1 = new Binding();

这就是我尝试过的......如何将datagridtemplate列绑定到图像？

这是以编程方式添加 DataGridTemplateColumn 的代码。

http://social.msdn.microsoft.com/Forums/en/wpf/thread/df77a277-91d4-41f1-a42a-0fa02a443ff4

DataGridTemplateColumn imgColumn = new DataGridTemplateColumn();
imgColumn.Header = "Image";

FrameworkElementFactory imageFactory = new FrameworkElementFactory(typeof(Image));
imageFactory.SetBinding(Image.SourceProperty, new Binding("ImgPath"));

DataTemplate dataTemplate = new DataTemplate();
dataTemplate.VisualTree = imageFactory;

imgColumn.CellTemplate = dataTemplate;

DGImages.Columns.Add(imgColumn);

我还添加了我创建的示例应用程序的源代码。希望能帮助到你。

你可以尝试更改为

<DataGridTemplateColumn Header="Image">

和

<Image Source="{Binding Image}" /> maybe this one 2
