Add buttons with a wpf datagridtemplatecolumn based on a linq for sql table

Question

I have a datagrid that I bind to a database table. Here is the XAML

<dg:DataGrid Name="dgContents" Grid.Column="1" AutoGenerateColumns="False" RowEditEnding="dgContents_RowEditEnding">
    <dg:DataGrid.Columns>
        <dg:DataGridTextColumn Binding="{Binding name}" Header="Name"></dg:DataGridTextColumn>
        <dg:DataGridTextColumn Binding="{Binding ip}" Header="ip"></dg:DataGridTextColumn>
        <dg:DataGridTemplateColumn Header="Progams">

        </dg:DataGridTemplateColumn>
    </dg:DataGrid.Columns>
</dg:DataGrid>

Here is the code I use to databind it. It's run on click from a treeview

public void changeFolder(int folderId)
{
    selectedFolder = folderId;
    var f = from c in rbdb.contents where c.folderId == folderId select c;
    dgContents.ItemsSource = f;
}

What I want is to create a number of buttons inside the datagridtemplate. I want one "add" button, then I want a dynamic number of buttons based on a SQL table thats called "commands". A click on the buttons should call a program, a right click should bring up a menu where the user can edit or delete the button. How do I do this?
