I know there is probably a simple solution, but I can't quite figure it out. Is there a way to convert the example above to select only one row, but still deselect on second press?

Essentially, I only want to allow 1 row to be highlighted at 1 time, I want to unhighlight (deselect) it on a cell_click if it is already highlighted (selected).

In the code snippets found below, you will find that I have it acting as I should, except it is not unhighlighting (deselecting) rows.

I feel like I am missing something that should be obvious, so any help would be greatly appreciated. Thanks!

My Globals:
B4X:
    Dim sRow As Int = 0
    Dim pRow As Int = 0

My CellClicked:
B4X:
Sub B4XRegister_CellClicked(ColumnId As String, RowId As Long)
    If pRow = RowId Then
        sRow = -1
        pRow = -1
        Dim Index As Int = B4XRegister.VisibleRowIds.IndexOf(RowId)
        SetRowColor(Index, False)
    Else
        sRow = RowId
        pRow = RowId
        Dim Index As Int = B4XRegister.VisibleRowIds.IndexOf(RowId)
        SetRowColor(Index, True)
    End If
End Sub

My SetRowColor:
B4X:
Sub SetRowColor(RowIndex As Int, Selected As Boolean)
    Dim clr As Int

    If Selected Then
        clr = SelectionColor
    Else
        If RowIndex Mod 2 = 0 Then
            clr = B4XRegister.EvenRowColor
        Else
            clr = B4XRegister.OddRowColor
        End If
    End If

    For Each c As B4XTableColumn In B4XRegister.VisibleColumns
        Dim pnl As B4XView = c.CellsLayouts.Get(RowIndex + 1) '+1 because of the header
        pnl.Color = clr
    Next
End Sub

I don't understand why you use it?

Don't you see the very first sentence:
