Situation:

A) I have a B4XTable view
B) I need that by clicking on any of the columns, I can change the background color of the entire row.

Basically what I want is for the USER to see which row was selected, showing it in another color.

Greetings

The easiest way Sergio is to use the extension class to B4XTable. Here is the link:

[B4X] B4XTableSelections - extended selection modes for B4XTable

B4XTableSelections extends B4XTable and adds new selection modes: SINGLE_CELL_TEMP - this is the built-in selection mode. Unlike the other selection modes it disappears automatically. SINGLE_CELL_PERMANENT - selection of a single cell. SINGLE_LINE_PERMANENT - selection of a single line...

You would choose in your case: SINGLE_LINE_PERMANENT - selection of a single line.
B4X: 
XSelections.Mode = XSelections.MODE_SINGLE_LINE_PERMANENT
    XSelections.SelectionColor=xui.Color_Green     'you can change the color of the row selected with this

Hello there @Mahares

I have followed your suggestions
Look at my surroundings:


I think I have the correct libraries, however it doesn't recognize "B4XTableSelections"
What I can be doing wrong?
Download this example (and it works!):

[B4X] B4XTableSelections - extended selection modes for B4XTable

B4XTableSelections extends B4XTable and adds new selection modes: SINGLE_CELL_TEMP - this is the built-in selection mode. Unlike the other selection modes it disappears automatically. SINGLE_CELL_PERMANENT - selection of a single cell. SINGLE_LINE_PERMANENT - selection of a single line...

UPS!!!!
My ignorance believed that it was included in "B4XCollections"
Adding "B4XTablesSelections.bas" came out working !!!!
It is also necessary to clarify that the following must be done (in addition to what you indicate above):

B4XTable1_DataUpdated: 
Sub B4XTable1_DataUpdated
...
    XSelections.Refresh
End Sub
Refresh the display when we change pages

B4XTable1_CellClicked: 
Private Sub B4XTable1_CellClicked (ColumnId As String, RowId As Long)
    XSelections.CellClicked(ColumnId, RowId) : Sleep(150)
...
End Sub
and we paint the row when selecting it

A million THANKS @Mahares
