Answer 1

You could use String.contains instead of an =.

Here is the MSDN article on the contains method:

http://msdn.microsoft.com/en-us/library/dy85x1sa.aspx

code to style the cell if it contains the search text:

    Dim someText As String = SearchTextBox.Text
    Dim gridRow As Integer = 0
    Dim gridColumn As Integer = 0
    For Each Row As DataGridViewRow In AccountsDataGridView.Rows
        For Each column As DataGridViewColumn In AccountsDataGridView.Columns
            Dim cell As DataGridViewCell = (AccountsDataGridView.Rows(gridRow).Cells(gridColumn))
            If cell.Value.ToString.ToLower.Contains(someText.ToLower) Then
                cell.Style.BackColor = Color.Yellow
            End If
            gridColumn += 1
        Next column
        gridColumn = 0
        gridRow += 1
    Next Row

Answer 2

Private Sub TextBox2_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox2.TextChanged

 For Each dr As DataGridViewRow In Me.DataGridView1.Rows

            If dr.Cells(0).Value.ToString.Contains(TextBox2.Text) Then dr.Visible = True Else dr.Visible = False


        Next
    End Sub

Well you could set the cell's background color with a different color to highlight all the matches, and select only the cell corresponding to the current match:

Dim searchIndex = 0
AccountsDataGridView.ClearSelection()
For Each row As DataGridViewRow In AccountsDataGridView.Rows
    For each cell As DataGridViewCell in row.Cells
        If CStr(cell.Value).Contains(SearchTextBox.Text, StringComparison.OrdinalIgnoreCase) Then
            If searchIndex = m_CurrentSearchIndex Then
                'This is the cell we want to select
                cell.Selected = True
            End If
            'Yellow background for all matches
            cell.Style.BackColor = Color.Yellow
            searchIndex += 1
        End If
    Next
Next

If m_CurrentSearchIndex has a value of 0, it would select the first match, second match for a value of 1, etc.
