my code:
dhxTree.attachEvent("onDrag",function(sid,tid){
if(tid == sid) return false; /* denies same people*/
var list = this.getSubItems(tid);
if (list.length == 0)
{
this.changeItemId(sid,tid+"_"+sid);/*sets new id*/
return true;
}
else
{
leaves = list.split(",");
for(var i =0; i < leaves.length;i++)
if(leaves[i]==tid+"_"+sid) return false; /* denies drag-n-drop*/
this.changeItemId(sid,tid+"_"+sid);/*sets new id*/
return true;
}
})
Source tree’s structure like this:
Level1:Area-A
Level2: Customer-A(id:13-11)
Level2: Customer-B(id:13-1)
Level1:Area-B
Level2: Customer-C(id:13-3)
Target tree’s structure like this:
Level1:Type-A
Level2: Customer-A (id: 13-11)
Level2: Customer-C (id: 13-3)
Level1: Type-B
Level2: Customer-B (id: 13-1)
1. drag “Customer-A”, drop “Customer-A”, action cancel, ok
2. drag “Customer-B”, drop “Customer-A”, add in, wrong item-id at line3, 6
Target tree’s structure like this:
/line1/Level1:Type-A
/line2/Level2: Customer-A (id: 13-11)
/line3/Level3: Customer-B (id: 13-1)
/line4/Level2: Customer-C (id: 13-3)
/line5/Level1: Type-B
/line6/Level2: Customer-B (id: 13-11_13-1)
3. drag “Customer-B”, drop “Customer-C”, add in, wrong item-id at line3, 5, 7
Target tree’s structure like this:
/line1/Level1:Type-A
/line2/Level2: Customer-A (id: 13-11)
/line3/Level3: Customer-B (id: 13-3_13-1)
/line4/Level2: Customer-C (id: 13-3)
/line5/Level3: Customer-B (id: 13-1)
/line6/Level1: Type-B
/line7/Level2: Customer-B (id: 13-11_13-1)
