how to bind the data from database to gridview and select a specified value from a column

provide this content in a xaml :

 <Grid>

        <DataGrid Background="{x:Null}" BorderBrush="#FFE21414" FontSize="14" FontStretch="Expanded" FontStyle="Italic" FontWeight="Medium" Foreground="#FFDE2828" Height="119" HorizontalAlignment="Left" Margin="77,32,0,0" Name="dgvPath" VerticalAlignment="Top" Width="326" AutoGenerateColumns="True" ItemsSource="{Binding}" />

        <GroupBox Header="user" Height="128" HorizontalAlignment="Left" Margin="146,162,0,0" Name="groupBox4" VerticalAlignment="Top" Width="171" Foreground="#FFDE2525" BorderBrush="#FFDE1A1A">

            <StackPanel DataContext="{Binding ElementName=dgvPath,Path=SelectedItem}">

                <Grid Height="117">

                    <Label Content="{Binding Path=name}" Foreground="#FFD81E1E" Height="28" HorizontalAlignment="Left" Margin="45,20,0,0" Name="lblSlave" VerticalAlignment="Top" Width="61" FontFamily="Script MT" FontSize="12" FontStretch="Expanded" />

                    <Button Content="Button" Height="23" HorizontalAlignment="Left" Margin="45,64,0,0" Name="button1" VerticalAlignment="Top" Width="75" Click="button1_Click" />

                </Grid>

            </StackPanel>

        </GroupBox>

    </Grid>

where <StackPanel DataContext="{Binding ElementName=dgvPath,Path=SelectedItem}"> in which dgvPath refers to datagridview name and <Label Content="{Binding Path=name}" Foreground="#FFD81E1E" Height="28" HorizontalAlignment="Left" Margin="45,20,0,0" Name="lblSlave" VerticalAlignment="Top" Width="61" FontFamily="Script MT" FontSize="12" FontStretch="Expanded" /> in which Content="{Binding Path=name}" in which name refers to column name from which the value is selected

use this in buttonclick event:

SqlConnection con = new SqlConnection("Data Source=raj=pc\\SQLEXPRESS;Initial Catalog=sampleDB;Integrated Security=True");

        private void button1_Click(object sender, RoutedEventArgs e)

        {

            con.Open();

            SqlDataAdapter da = new SqlDataAdapter("select * from complaintsdetails",con);

            DataSet ds = new DataSet();

            da.Fill(ds, "ss");

            this.DataContext = ds.Tables["ss"];

            con.Close();

        }
