Question

I’m using WPF DataGrid and there is an extra column on the right side.

How can I remove it ?

XAML:

 <Grid>
    <DataGrid ItemsSource="{Binding Persons}" Background="LightBlue" AutoGenerateColumns="False" Width="200">
        <DataGrid.Columns>
            <DataGridTextColumn Header="First Name" Binding="{Binding FirstName}" Width="200"/>
        </DataGrid.Columns>
    </DataGrid>
</Grid>

You can set RowHeader width to 0, but not actually remove the RowHeader itself, as far as I know. You can use this line of code after InitializeComponent():

 dataGrid.RowHeaderWidth = 0;

EDIT: Note that user will not be able to select rows(for example for deleting) if you do this.
