Question

I’ve got a DataGrid whose main purpose is to allow the user to enter data in its cells.

However, the first field in this grid should display the contents of a list.

How would I go about setting the data source for just one column?

EDIT: I want to achieve something like this:

Specify your own DataGridTemplateColumn in DataGrid.Columns, and set the DataGridTemplateColumn.CellTemplate to whatever it is you’re looking to place in that column.

For example, if you wanted it to be a ComboBox pointing to some other list of fields:

<DataGrid.Columns>
    <DataGridTemplateColumn Header="Fields">
        <DataGridTemplateColumn.CellTemplate>
            <DataTemplate>
                <ComboBox ItemsSource="{Binding ElementName=MyWindow, Path=DataContext.SomeCategoryList}"
                          SelectedItem="{Binding SomePropertyOnDataItemInRow}" />
        </DataGridTemplateColumn.CellTemplate>
    </DataGridTemplateColumn>
</DataGrid.Columns>

I’m using a property called SomeCategoryList that’s on MyWindow.DataContext, however you can set the binding to point to wherever your field list is stored
