Adding only 1st Row of Datagrid with combobox

Dec 15, 2009 at 4:21 PM
I am trying to add 1st row of the Datagrid to be one with a mulitpl selection(Combox). The other rows will be will be editable text. I do this by binding to a dataset. If I want an extra column I am able to do it easily by adding a templatedcolumn in the XAML datagrid. 
Is there some way to similarly add row.
P.S(The requirement is to reverse the rows and columns to avoid scrolling).
I have pasted below the sample code.
<Grid Height="339" Width="697">
        <Label Margin="96,33,379,206">Name:</Label>
        <Label Name="tableName" Content="{Binding Name}"  Margin="143,33,176,267"></Label>
        <Label Margin="67,62,411,238">Reset Action:</Label>
        <ComboBox Height="23" HorizontalAlignment="Left"  Margin="152,62,0,0" ItemsSource="{Binding ResetAction}"  SelectedValue="{Binding Path=ResetAction}"  Name="resetaction"  VerticalAlignment="Top" Width="120" />
        <dg:DataGrid IsReadOnly="False"  Name="tablegrid" AutoGenerateColumns="True"  RowHeight="20" Margin="152,91,58,39">
        <Button Name="Addbutton" Click="Addbutton_Click" Margin="258,303,378,9">Add</Button>
        <Button Name="Deletebutton" Click="Deletebutton_Click" Margin="0,306,309,9" HorizontalAlignment="Right" Width="53">Delete</Button>
