Android Question B4XTable pnlTitle.Visible pnlHeader.Visible can't set to False

[VArt]

In example "Cross platform Editable B4XTable + Form"
add only one line

Private Sub B4XPage_Created (Root1 As B4XView)


'original example code


B4XTable1.pnlHeader.Visible=False  'my line

End Sub

Get error: "java.lang.RuntimeException: Object should first be initialized (B4XView)."

What way to hide navigation panel?

Need this, because my table is short, have fixed numbers of rows & columns and always visible. Therefore, navigation - not needed.

Add Sleep(0) before this line. It will allow the table layout to be loaded.

Thanks, Erel!

It works!


Problem solved

but...

table not shift to up, i have top empty space.

I'm trying to do this:

(BT - B4XTable)

BT.mBase.GetView(1).Top=0 'panel of table
BT.mBase.Height=BT.mBase.Height - BT.mBase.GetView(0).Height ' minus height of hided Header


Visual result is ok!
This is correct way?
Or may be exist more simple solution to shift up or redraw after hiding of header?

Another option is to put B4XTable inside a Panel and set its top to -60dip (pnlHeader.Height).
