programatically add a image in Datagrid template c#


The following xaml code binds the "Image" with the datagrid template column.

     <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();

this is what i have Tried.... how to bind the datagridtemplate column to a image ??


Solution

  • Here is the code to add a DataGridTemplateColumn programatically.

    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);
    

    I have also added the source code of the sample app that I created. Hope it helps.
