Vb.net – DataGridView cell search using a LINQ query

I'm still relatively new to LINQ, and have done more stumbling around than anything, but I have really liked what I have seen so far. So with that in mind, I have a VB.NET search routine, part of which is provided, below, that checks all Text cells in a DataGridView for a given string (inclusive), using a basic set of nested loops to perform the search:

' Search for the first occurrence of the given string
For Each row As DataGridViewRow In dgvMembers.Rows
    ' Skip the new row
    If row.IsNewRow Then Exit For

    ' Loop through all the cells in the current row
    For Each cell As DataGridViewCell In row.Cells
        ' Skip non-text cells
        If cell.GetType IsNot GetType(DataGridViewTextBoxCell) Then Continue For

        ' Search for our matching text
        If cell.Value.ToString.ToUpper.Contains(searchText) Then
            ' Select the cell if we have a match
            dgvMembers.CurrentCell = cell
            WriteMessage("String '{0}' found.", searchText)
            Exit Sub
        End If
    Next
Next

' If we get to this point, we didn't find anything
WriteMessage("String '{0}' NOT found.", searchText)

Pretty straightforward. Now, my question is: is there a way to replicate this behavior using LINQ? Basically I would like the query to select (or return) the first DataGridViewCell whose text contains the search string. I've done some tinkering with sub-queries and the like, but I'm still having trouble wrapping my brain around the concepts (too many years of writing T-SQL, I guess).

Obviously the nested loop works fine, so this is more of a curiosity, really. Thanks in advance!
