Should be no problem,

If tv_1. The getitem (ii_handle, tv_item)=1 then return
Tv_item. Label=ls_mess
The select Max (to_number (treeid)) into: ls_treeid from bm_bqbmb0_tree;
Ll_treeid=long (ls_treeid) + 1
Ls_parentid=string (tv_item. Data)
Ls_treeid=string (ll_treeid)
Insert into bm_bqbmb0_tree (treeid, treename, parentid)
Values (: ls_treeid, : ls_mess, : ls_parentid);
If the sqlca. Sqlcode<> 0 then
Messagebox (" prompt ", "generate data failed!" + the sqlca. Sqlerrtext)
Return
The else

end if

CodePudding user response:

Is this sentence tv_1 insertitemlast (ii_handle ltvi_new)
Plus it will increase the two nodes, without a also don't show, but the database is right, only added a data

CodePudding user response:

In ExpandItem ever written, or other place

CodePudding user response:

One is to increase the yourself, and a is itempopulate activates automatically add

You can be increased in such processing

CodePudding user response:

If add this if tv_cur. On the basis of my ExpandedOnce=true and tv_cur. Children=true then
It is ok to judge? How do I add new did not show up in the interface

CodePudding user response:

Is that before adding nodes, you can judge
