How can I programatically select the record in the dropdown that matches the text typed in ?

You can handle DropDown event of comboBoxAdv1 and set as shown in the following code snippet.

C#

private void comboBoxAdv1_DropDown(object sender, System.EventArgs e)

{

this.comboBoxAdv1.ListBox.SelectedItem=this.comboBoxAdv1.TextBox.Text ;

}

VB

Private Sub comboBoxAdv1_DropDown(ByVal sender As Object, ByVal e As System.EventArgs)

Me.comboBoxAdv1.ListBox.SelectedItem =Me.comboBoxAdv1.TextBox.Text End Sub
