Actually this is not quite simple.
Version 10.12 handles this properly.

I already requested my company for new FHW upgrade 11.1
I guess I need to wait for that.

Dear Silvio,

In my case, I used VK_DELETE key assign it to bKeyChar with code block alias->( dbdelete() ) and refresh the xbrowse.

if you mean the ::oTreeItem:Delete(), doesn't work perfectly with my case.

Kind regards,
Frances

My alternate solution is to exclude a record matching my condition..

Thank you for your suggestion.

Yes. For the time being, you can delete the record from the original data and then reconstruct the tree and refresh the browse. Seems very crude solution but works quite well and I myself used it under complex situations without hitting the performance.

Hello,

in other way are there the option to create a subtree or tree on run-time, per example all the item in the xbrowse are level 0 in the tree then by double click or another method we add a tree for the current row in the xbrowse and open it.

Marcelo

Yes.

Code (fw): Select all Collapse

WITH OBJECT oBrw:oTreeItem
   :SetTree( oSubTree )
   :Open()
END
oBrw:Refresh()

Hello again.

because I have thousands of records, I want to know if it possible to have a normal xBrowse database associated
with the possibility to make a tree in some row by demand, no for all, only for selected row

thanks in advance

Please try this:

Create browse of the DBF in the normal way.
Insert this line:

Code (fw): Select all Collapse

oBrw:SetTree( 1 )

just before activating window or dialog.

Now the browse will be on oBrw:oTree created automatically by XBrowse and each oItem of the oTree having the record number of the dbf.
When the tree is navigated, the dbf goes to the record. The browse will still look like the one you created on the dbf.

Now you add a child tree to any item you want.
