Search datagridview on user keypress

Question

I\'m trying to select the first row where the cell value starts with the same keychar the user pressed. That\'s the part that is giving me trouble.

Here\'s how I\'m hand

This is a VS2008 VB.NET DataGridView extension meant to do kind of what you are doing but using a TextBox for searching information (not designed with case in mind but could easily be added). This extension works so perhaps there is something that might be helpful. I did notice that your code selects a row using select where mine uses CurrentCell.

     _
Public Function PartSeek(ByVal GridView As DataGridView, ByVal ColumnName As String, ByVal Value As String, ByVal Part As Boolean) As Boolean
    Dim Located As Boolean = False

    If GridView.Columns.Contains(ColumnName) Then
        Dim SingleRow As DataGridViewRow
        If Part Then
            SingleRow = (From Rows In GridView.Rows.Cast(Of DataGridViewRow)() _
                         Where Rows.Cells(ColumnName).Value.ToString().Contains(Value)).FirstOrDefault
        Else
            SingleRow = (From Rows In GridView.Rows.Cast(Of DataGridViewRow)() _
                         Where Rows.Cells(ColumnName).Value.ToString() = Value).FirstOrDefault
        End If
        If Not IsNothing(SingleRow) Then
            If GridView.CurrentCell.RowIndex <> SingleRow.Index Then
                GridView.CurrentCell = GridView(0, SingleRow.Index)
            End If
            DirectCast(GridView.Parent, Form).ActiveControl = GridView
            Located = True
        End If
        Return Located
    Else
        Throw New Exception("Column '" & ColumnName & "' not contained in this DataGridView")
    End If

End Function
