Dynamically binding a datagrid WPF

I'm binding data to a datagrid dynamically but it does not shows the data. It gives me this five columns in it: RowError, RowState, table, ItemArray and HasError.

But the row count is correct it gives same row count as I have in database.

This is the Vb code:

Dim con As New OdbcConnection("dsn=PAUSPAN")
con.Open()
Dim cmd As New OdbcCommand("select * from tbl_chart", con)

Dim da As New OdbcDataAdapter(cmd)
'Dim dt As New DataTable("a")
Dim ds As New DataSet()
ds.Tables.Add("a")

da.Fill(ds, "a")
MsgBox(ds.Tables("a").Rows.Count.ToString)

DataGrid1.ItemsSource = ds.Tables("a").AsEnumerable.ToList()
'DataGrid1.DataContext = ds.DefaultViewManager

con.Close()

And this is the XAML code:

<Window x:Class="datagrid"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"        
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="datagrid" Height="344" Width="599">
    <Grid>
        <Button Content="Button" Height="23" HorizontalAlignment="Left" Margin="486,225,0,0" Name="Button1" 
                VerticalAlignment="Top" Width="75" />
        <DataGrid Height="241" HorizontalAlignment="Left"
                  Margin="12,12,0,0" 
                  Name="DataGrid1" VerticalAlignment="Top"
                  Width="386" ItemsSource="{Binding ds}" />
    </Grid>
</Window>

how to solve this problem? how do it bind the dataset to datagrid dynamically?

Bind ItemsSource with DataView instead of DataTable. You can get DataView with either of the approaches mentioned below -

DataGrid1.ItemsSource = ds.Tables("a").DefaultView;

OR use extension method AsDataView -

DataGrid1.ItemsSource = ds.Tables("a").AsDataView();

You are a bit mixing dynamic and static binding. you should remove ItemsSource="{Binding ds}" from XAML and DataGrid1.DataContext = ds.DefaultViewManager from code behind as you're communicating with ItemsSource from code behind.
