Solution 1

I Hope following solution will help you

Key Features:

1) DataTable : to store data from database and to bind this data with data grid
2) ValueConverter : Convert column value to specified image source
3) DataTemplate : Template for grid column having image type

1) DataTable : here i have used static table you can fetch data from database

DataTable dt = new DataTable();
DataRow dr = dt.NewRow();
dr["Name"] = "tick";
grid1.ItemsSource = null;
grid1.ItemsSource = dt.DefaultView;

2) Value Converter

[ValueConversion(typeof(string), typeof(SolidColorBrush))]
      public class StringConverter : IValueConverter
          public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
              string val = value.ToString();
              return "/FormWithTab;component/Images/" + val + ".png";

          public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
              throw new NotSupportedException();

3) DataTemplate

<pre><window x:class="FormWithTab.Window2" xmlns:x="#unknown">
         xmlns:wpf="" Loaded="Window_Loaded"
    Title="Window2" Height="300" Width="300">
        <local:stringconverter x:key="NameToStringConverter" xmlns:local="#unknown" />
        <datatemplate x:key="ImageColTemplate">
            <image x:name="img" stretch="None" horizontalalignment="Center" source="{Binding Name,  Converter={StaticResource NameToStringConverter}}" />
        <wpf:datagrid x:name="grid1" verticalalignment="Top" height="150" autogeneratecolumns="False" xmlns:wpf="#unknown">
                <wpf:datagridtemplatecolumn header="Image" celltemplate="{StaticResource ImageColTemplate}" />
