Datagrid圖像列以編程方式添加wpf

我正在尋找一種方法，我如何以編程方式將一列顯示圖像添加到數據網格。我一直在尋找如何找到解決方案很長一段時間沒有成功。Datagrid圖像列以編程方式添加wpf

我現在做它的方式是這樣的：

DataGridTemplateColumn col1 = new DataGridTemplateColumn(); 
col1.Header = "Betaald"; 
FrameworkElementFactory factory1 = new FrameworkElementFactory(typeof(System.Windows.Controls.Image)); 
Binding b1 = new Binding("Picture") { Mode = BindingMode.TwoWay }; 
factory1.SetBinding(System.Windows.Controls.Image.SourceProperty, b1); 
DataTemplate cellTemplate1 = new DataTemplate(); 
cellTemplate1.VisualTree = factory1; 
col1.CellTemplate = cellTemplate1; 
dtgVerkoopsdocumenten.Columns.Add(col1);

這應該創建一個列在那裏我可以顯示圖片。所有數據，我從一個數據庫，這是我在colums存儲這樣得到：

System.Windows.Controls.Image image = new System.Windows.Controls.Image(); //this is on top of my class 

MySqlDataReader reader = cmd.ExecuteReader(); 
while (reader.Read()) 
{ 
    string naam = getKlant(reader.GetInt32(2)); 

    if (reader.GetBoolean(7) == false) 
    { 
     BitmapImage betalen = new BitmapImage(new Uri("/WpfApplication1;component/Images/false.png", UriKind.Relative)); 
     image.Source = betalen; 
    } 
    else 
    { 
     BitmapImage betalen = new BitmapImage(new Uri("/WpfApplication1;component/Images/true.png", UriKind.Relative)); 
     image.Source = betalen; 
    } 

    dtgVerkoopsdocumenten.Items.Add(new DataItem 
    { 
     ID = reader.GetInt32(1), 
     klant = naam, 
     netto = reader.GetDouble(3), 
     btw = reader.GetDouble(4), 
     bruto = reader.GetDouble(5), 
     datum = reader.GetDateTime(6).ToString("dd-MM-yyyy"), 
     soort2 = soort, 
     Picture = image 
     }); 
    } 
    reader.Close();

DataItem的是自己製作類，我保存在我的所有綁定：

//more code, but the one below is the one I'm talking about 
public System.Windows.Controls.Image Picture { get; set; }

我現在得到絕對沒有。我沒有得到任何錯誤。

所以我的問題是：如何將圖像存儲到數據網格中，而不必太多地混淆xaml文件。

輸出：

System.Windows.Data Error: 1 : Cannot create default converter to perform 'two-way' conversions between types 'System.Windows.Controls.Image' and 'System.Windows.Media.ImageSource'.

BindingExpression:Path=Picture; DataItem='DataItem' (HashCode=435249); target element is 'Image' (Name=''); target property is 'Source' (type 'ImageSource')

你需要它作爲一個2路綁定模式？如果沒有，請將其更改爲單向 – 2013-04-23 15:40:11

我試過這樣做，唯一發生變化的是在輸出窗口中「雙向」到「單向」。 – 2013-04-23 15:44:36

看看[這個答案]（http://stackoverflow.com/a/3427387/1466627）修復你的圖像到ImageSource錯誤。 – 2013-04-23 15:46:05

您應該使用的，而不是SetValue的SetBinding方法，因爲你是分配結合的財產，而不是分配價值的財產。

來源：

factory1.SetValue(System.Windows.Controls.Image.SourceProperty, b1);

要：

factory1.SetBinding(System.Windows.Controls.Image.SourceProperty, b1);

你約束力的聲明也可以寫爲：

Binding b1 = new Binding("Picture") { Mode = BindingMode.TwoWay };

我仍然沒有在我的datagrid。 – 2013-04-23 15:01:41

@RobbeVanWinckel輸出窗口中什麼都沒有？ – 2013-04-23 15:14:27

檢查主帖以查看輸出。 – 2013-04-23 15:21:12
