sfComboBox1.TextBox.TextChanged += SfComboBox1_TextChanged;
sfComboBox1.SelectedIndexChanged += SfComboBox1_SelectedIndexChanged;
 
private void SfComboBox1_TextChanged(object sender, EventArgs e)
{
     //Text changed
     var selectedText = ((TextBox) sender).Text;
}
 
private void SfComboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
}

AddHandler sfComboBox1.TextBox.TextChanged, AddressOf SfComboBox1_TextChanged
AddHandler sfComboBox1.SelectedIndexChanged, AddressOf SfComboBox1_SelectedIndexChanged
 
Private Sub SfComboBox1_TextChanged(ByVal sender As Object, ByVal e As EventArgs)
'Text changed
Dim selectedText = (CType(sender, TextBox)).Text
End Sub
