WPF add image to cell in column
提问by lemunk
Using C#.NET4.5, Visual Studio 2012, WPF.
使用 C#.NET4.5、Visual Studio 2012、WPF。
Well here's how far I got with a lot of help from great people and advice!
好吧，这就是我在伟大人物和建议的帮助下取得的进展！
Set up a new column for images:
为图像设置一个新列：
DataGridTemplateColumn p1 = new DataGridTemplateColumn();
p1.Header = "p1";
FrameworkElementFactory factory1 = new FrameworkElementFactory(typeof(System.Windows.Controls.Image));
Binding b1 = new Binding("picture");
b1.Mode = BindingMode.TwoWay;
factory1.SetValue(System.Windows.Controls.Image.SourceProperty, b1);
DataTemplate cellTemplate1 = new DataTemplate();
cellTemplate1.VisualTree = factory1;
p1.CellTemplate = cellTemplate1;
paretogrid.Columns.Add(p1);
Then I check each "row" and set up some Ifs to check values:
然后我检查每个“行”并设置一些 Ifs 来检查值：
private void ShowArrows()
{
var rows = GetDataGridRow(paretogrid);
foreach (DataGridRow r in rows)
{
DataRowView rv = (DataRowView)r.Item;
var par3 = paretogrid.Columns[7].GetCellContent(paretogrid.Items[2]) as TextBlock;
int pconv3 = Convert.ToInt32(par3.Text);
var par2 = paretogrid.Columns[8].GetCellContent(paretogrid.Items[2]) as TextBlock;
int pconv2 = Convert.ToInt32(par2.Text);
var par1 = paretogrid.Columns[9].GetCellContent(paretogrid.Items[2]) as TextBlock;
int pconv1 = Convert.ToInt32(par1.Text);
var parNew = paretogrid.Columns[10].GetCellContent(paretogrid.Items[2]) as TextBlock;
int pconvNew = Convert.ToInt32(parNew.Text);
if(pconv3 == pconv2)
{
paretogrid.Columns[12].
}else
if(pconv3 > pconv2)
{
//uparrow
}
else
if (pconv3 < pconv2)
{
//down
}
}
}
So as you can see I step through, throw it into a few nested conditions then where the comments are is where I want to add the images, something like :
因此，正如您所看到的，我逐步完成，将其放入一些嵌套条件中，然后注释所在的位置就是我要添加图像的位置，例如：
paretogrid.columns[12].setvalue(can image go here? asks for dependency);
not sure how to add the image all I see is adding images to an entire column via the item source.
不知道如何添加图像我看到的只是通过项目源将图像添加到整个列。
Where am I going wrong?
我哪里错了？
EDIT: 08/04/2013Ok got two suggestions, so far no errors are happening which is always nice to me. unfortunatly no images are showing up.
编辑：08/04/2013好的，有两个建议，到目前为止没有发生错误，这对我来说总是很好。不幸的是没有图像显示。
Datagrid.Children.Add();
for some reason my datagrid does not have this .Children method in the intellisense, even when I force it it just redlines me. What am I missing?
出于某种原因，我的数据网格在智能感知中没有这个 .Children 方法，即使我强制它只是红线我。我错过了什么？
Not big on XAML so heres the grid.
XAML 不大，所以这里是网格。
Grid Margin="10,13,6,-13" Background="{DynamicResource {x:Static SystemColors.ActiveCaptionTextBrushKey}}" HorizontalAlignment="Left" Width="1442">
<DataGrid Name ="paretogrid" HorizontalAlignment="Left" Height="500" Margin="16,63,0,0" VerticalAlignment="Top" Width="1126" RenderTransformOrigin="0.5,0.5" Background="{x:Null}" FontSize="14" SelectionChanged="paretogrid_SelectionChanged">

I don't have exactly your environment (VS2012 and Windows 8), but in wpf you can access properties also with the SetValue()method. You could try to use something like this:
我没有完全符合您的环境（VS2012 和 Windows 8），但在 wpf 中，您也可以使用该SetValue()方法访问属性。你可以尝试使用这样的东西：
Image img = new Image();
img.SetValue(Grid.ColumnProperty, "2");
img.SetValue(Grid.RowProperty, "1");
Hope it helps.
希望能帮助到你。
I have tested a small demo on my machine and it works well. Here is the xaml:
我在我的机器上测试了一个小演示，它运行良好。这是xaml：
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Grid x:Name="paretoGrid">
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
</Grid>
and the code behind:
以及背后的代码：
var img = new Image {Width = 100, Height = 100};
var bitmapImage= new BitmapImage (new Uri(@"pack://application:,,,/Images/old-go-down.png"));
img.Source = bitmapImage;
img.SetValue(Grid.RowProperty, 1);
img.SetValue(Grid.ColumnProperty, 1);
paretoGrid.Children.Add(img);
Image Build Action has to be set as Resource.
Image Build Action 必须设置为Resource。
