The theme with lowercase characters gives my backcolor in the column 'mnr'. The theme with upercase characters gives a white background in the column 'TABEL'.
Here my code to create the rows.
B4X:
For i = 65 To 67 'Add row A,B,C
Dim rCellThemes As List
rCellThemes.Initialize
tblTelling.AddRow(i,Array As String(Chr(i), i,"","","","","","",""))
rCellThemes.AddAll(Array As String("ABCcenter","abccenter","ABCcenter","ABCcenter","abcright","abcright","abcright","abcright","abcright"))
tblTelling.SetRowThemes(rCellThemes)
Next
Just like normal B4X, ABCcenter and abccenter is exactly the same (internally they are lowercases). This prevents making very hard to find typing bugs.
then there must be something else wrong in your code because two different theme names are certainly respected (I do it all the time in my own apps). But looking at both themes in your first post, aren't they exactly the same too? Looking at that code it doesn't matter which theme you pick, it has the same settings. Or I'm missing something completely? (quite possible, as it is my last day before the summer holidays, concentration is a bit low )
It is indeed the same code. This was to point out that the same code produced a differend result. I'll make a small sample project tomorrow and upload it.
