Thanks Erel.

The first tableview was added to the Mainform using the Scene Builder and then I generated the members.

I decided to try adding another tableview to the Mainform in CODE and interestingly everything displays fine when I add and display the the same data using the same subs(tableview).

So now we have two tableviews(one in the layout and the other added in code), the first one has the data but does not show, the second works fine.

If that is not enough for you, I will upload the project.

Thanks,
Hilton.

Hi Erel,

The attached program is one that I am simply using to learn about b4j.

Erel,

My apologies, I must have done it wrong as it is the first time I have tried.

Hilton.

It was indeed confusing. You should first create the columns:

B4X:

Sub setTvHeadings(tv As TableView)
   MainForm.Title = "People"
   tv.SetColumns(Array As String("Col1", "Col2", "Col3")) '<----- C
   tv.SetColumnHeader(0,"Name")
   tv.SetColumnHeader(1,"Dob")
   tv.SetColumnHeader(2,"Age")
End Sub

Erel,

I foolishly assumed that setting up the columns in the Scene Builder that they would have been created for me. Ok, no more assuming!

Thank you very much,
Hilton.
