DataGrid shows image path instead of image itself

Question

The following lines finish showing the path instead of the image to which it leads. AutoGenerateColums is set to true; setting it to false will result in completely empty lines.

System.Data.DataTable DataTable = new System.Data.DataTable();
System.Data.DataColumn DataColumn = new System.Data.DataColumn();

Uri uri = new Uri(@"C:/Users/User/Desktop/szagdoga/error.png");
BitmapImage img = new BitmapImage(uri);
DataColumn.DataType = img.GetType();
DataColumn.ColumnName = ("this");

DataTable.Columns.Add("Test #");
DataTable.Columns.Add(DataColumn);
DataTable.Columns.Add("Min Range");
DataTable.Columns.Add("Max Range");
DataTable.Columns.Add("Result");
for (int i = 6; i <50; i++)
    DataTable.Rows.Add(ExcelFile[0, i],img, ExcelFile[1,i],0,0,0);

ChannelDataGrid.ItemsSource = DataTable.DefaultView;

Please help me show the images somehow! Thank.

Answer 1

, DataGrid DataGridTextColumns, AutoGeneratingColumn . DataGridTemplateColumn, ( DataTable). .

:

xaml part

<DataGrid Name="ChannelDataGrid" AutoGeneratingColumn="ChannelDataGrid_OnAutoGeneratingColumn">

    <DataGrid.Resources>
        <DataTemplate x:Key="ImgCell">
            <Image Source="{Binding Path=Img}"/>
        </DataTemplate>
    </DataGrid.Resources>        
</DataGrid>

:

private void InitializeDataTable()
{
    System.Data.DataTable DataTable = new System.Data.DataTable
    {
        Columns = {"Test #", "Img", "Min Range", "Max Range", "Result"}
    };

    Uri uri = new Uri(@"C:/Users/User/Desktop/szagdoga/error.png");

    for (int i = 6; i < 50; i++)
        DataTable.Rows.Add(ExcelFile[0, i], uri, ExcelFile[1, i], 0, 0);

    ChannelDataGrid.ItemsSource = DataTable.DefaultView;
}

private void ChannelDataGrid_OnAutoGeneratingColumn(object sender, DataGridAutoGeneratingColumnEventArgs e)
{
    if (e.PropertyName == "Img")
    {
        // replace text column with image column
        e.Column = new DataGridTemplateColumn
        {
            // searching for predefined tenplate in Resources
            CellTemplate = (sender as DataGrid).Resources["ImgCell"] as DataTemplate,
            HeaderTemplate = e.Column.HeaderTemplate,
            Header = e.Column.Header
        };
    }
