iStock_000015057287XSmallThis snippet is from my archives and reminds me how to setup column names for a WPF/Silverlight datagrid and bind them to the data by not using AutoGenerateColumn feature. (See below for the visual end result.)

DataGrid Column Names Setup in Xaml

In this example we will have two columns where the data will be filename strings. We will specify the columns in the Xaml to use the DataGridTextColumn and not to dynamically generate columns on our Datagrid:

<DataGrid x:Name="dgOperation" AutoGenerateColumns="False">
    <DataGrid.Columns>
        <DataGridTextColumn Header="File Name Before" Binding="{Binding Path=Original}"/>
        <DataGridTextColumn Header="File Name After"  Binding="{Binding Path=New}"/>
    </DataGrid.Columns>
</DataGrid>

The result is that the header row will have two columns with the name “File Name Before” and “File Name After” will subsequently bind them to a data object with the property names of “Original” and “New”.

Actual Binding During the Loading of the Grid

We will read in a directory for the WPF example from the hard drive and fill the original file names to the first column and a generated name for the second column. Since we have specified in the Xaml that we are binding to “Original” and “New” properties the dynamic linq object created will have those properties.

dgOperation.ItemsSource = Directory.GetFiles( @"C:\" )
                                   .Select( ( nm, index ) => new
                                       {
                                          Original = System.IO.Path.GetFileName( nm ),
                                          New = string.Format( "{0}_{1}{2}", System.IO.Path.GetFileNameWithoutExtension( nm ),
                                                                             index,
                                                                             System.IO.Path.GetExtension( nm ) )
                                        } );

The result is as below:

DataGridBind

Note: Out of the box editing the rows will throw an exception. To fix that make each of the rows read only.
