How can I use LINQ to find a DataGridView row?

Question

Is there any way to use a LINQ style query to find a DataGridView row? I am trying to find the one bound to a specific object and highlight it.

MyDatagrid.R

For those who came here looking for the VB-version, Lee's answer translates to:

MyDatagrid.Rows.Cast(Of DataGridViewRow)().FirstOrDefault(Function(r) r.DataBoundItem Is myItem).Selected = True

Furthermore, if you're like me, and are using this to find your DataGridViewRow from your bound DataTable.DataRow (DataGridView.DataSource = DataTable), then you can access it like this:

Dim MyDataRowSearch() As DataRow = MyDataTable.Select("SomeColumn = SomeValue")
If MyDataRowSearch.Count = 1 Then
  MyDataGrid.Rows.Cast(Of DataGridViewRow)().FirstOrDefault(Function(r) DirectCast(r.DataBoundItem, DataRowView).Row Is MyDataRowSearch(0)).Selected = True
End If

This is much more efficient than looping through your DataGridView looking for matching values.
