How to filter in datagridview on keypress in vb.net

I need to filter the product on key press. I have below code but its not working. how to do it?

Private Sub TextBox3_KeyPress(sender As Object, e As KeyPressEventArgs) Handles TextBox3.KeyPress
        Me.Test_LaunchTableAdapter.Fill(Me.DataSet1.Test_Launch)
        Me.DataGridView1.Visible = True
        Dim dv As DataView
        dv = New DataView(Me.DataSet1.Test_Launch, "(convert([Code Article], 'System.String') like '%" & TextBox3.Text & "%')", Nothing, DataViewRowState.CurrentRows)
        DataGridView1.DataSource = dv
    End Sub

But I am getting this error

> System.NotSupportedException: The DataSource property of the containing DataGridView control must be set to a BindingSource.

in this line getting error

DataGridView1.DataSource = dv

The code you have is crazy. Every time the user presses a key, you query the database and get the same data you already have, then filter it locally. Don't do that. Query the database once and populate your DataTable, bind that to a BindingSource and bind that to your DataGridView. You should then set the Filter property of your BindingSource on the TextChanged event of your TextBox:

myBindingSource.Filter = $"[Code Article] LIKE '%{TextBox3.Text}%'"

Better still, restart a Timer on the TextChanged event and then set the Filter on the Tick of that Timer. That way, you won't be filtering over and over when the user types multiple characters in a row. You can experiment with the Interval so that the user doesn't have to wait too long after they stop typing to see the filtered data but long enough that they can type multiple characters without filtering occurring after each one. Something around 300 milliseconds is a good place to start. I'll leave that to you as an exercise. Note that you'd call Stop and Start on the Timer in the TextChanged event and then Stop on the Tick event.
