I've this code:
Code:
TextBox1.AutoCompleteMode = AutoCompleteMode.Append
TextBox1.AutoCompleteSource = AutoCompleteSource.CustomSource
If dttest.Rows.Count > 0 < 2 Then
For counter As Integer = 0 To dttest.Rows.Count - 1
TextBox1.AutoCompleteCustomSource.Add(dttest.Rows(counter)("test"))
Next
For counter As Integer = 0 To dttest.Rows.Count = 328
If dttest.Rows(0).Item(0).ToString = TextBox1.Text Then
.....
End If
But textbox doesn't get the autocomplete mode, in this way, it need only to check the rows of datatable, and if find correct match with one on textbox then append the left text.
