VB

 Private Function FindItems(ByVal strSearchString As String) As Boolean
    dgvsearchitem.ClearSelection()
 For Each myRow As DataGridViewRow In dgvsearchitem.Rows
        For Each myCell As DataGridViewCell In myRow.Cells
            If InStr(myCell.Value.ToString, strSearchString,CompareMethod.Text) Then
                myRow.Selected = True
                Return True
            End If
        Next
    Next
    Return False

End Function
 Private Sub txtitemsearch_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles txtitemsearch.KeyDown
    If (e.KeyCode = Keys.Enter Or e.KeyCode = Keys.Down Or e.KeyCode = Keys.Tab) And txtiname.Text <> "" Then
        dgvsearchitem.Focus()

    End If

Have you tried to select the row AFTER giving it the Focus ?

This code works for me..
I have an own implementation of DataGridView and my data is bound to a BindingSource _BS..
Maybe you can give it a shot.

VB

Public Function FindValue(ByVal tcValue As String, Optional ByVal tcColumn As String = "") As Boolean
   If Not String.IsNullOrEmpty(tcValue.Trim) Then
      Dim lcColumn As String = Me.CurrentCell.OwningColumn.DataPropertyName
      If Not String.IsNullOrEmpty(tcColumn) Then
         lcColumn = tcColumn
      End If
      If String.IsNullOrEmpty(lcColumn) Then
         lcColumn = Me.CurrentCell.OwningColumn.Name 
      End If
      For Each loRow As DataGridViewRow In Me.Rows
         If loRow.Cells(lcColumn).EditedFormattedValue.ToString.ToUpper().StartsWith(tcValue.ToUpper()) Then
            Me._BS.Position = loRow.Index
            Return True
         End If
      Next
   End If
   Return False
End Function

Solution 2

If your problem is still not solved :

The right Syntax for that use is :

VB

dgvsearchitem.rows(yourIndex).Selected = True
