Drag and drop in ALV tree
Hi All,
I have a small requirement, I have to implement drag and drop functionality in ALV ( simple trees ) in such a way that the entire contents ( Folders and its sub folders ) have to be copied. As of now i am able to drag and drop
one at a time, ie drag and drop folder and then again drag and drop its sub folder. Any solution to drag and drop both folder and its sub-folders in one step.
example program -> rsdemo_drag_drop_tree_multi which allows drag and drop of folders one at a time.
Thanks and Regards,
Kiran.
Hi ,
just type BCALV_DND_* in se38 editor and press f4 you will get log of examples for drag n drop funtionality.

Help needed in drag and drop of Flex tree
Hi,
We have an application which allows drag and drop between
multiple
trees and lists.
Here are the steps I follow to refresh on drag and drop:
1. Dispatch a custom event which calls server.
2. On successful response from server I change the model
which is
data provider for the tree.
3. Then, set a flag which triggers 'invalidateDisplayList'
and 'invalidateList' for tree (and other listeners).
4. The tree refreshes fine. But as soon as I drag and drop
between
trees again, I get this error in Tree.as:
TypeError: Error #1010: A term is undefined and has no
properties.
at mx.controls::Tree/::updateDropData()
at mx.controls::Tree/calculateDropIndex()
at mx.controls.listClasses::ListBase/showDropFeedback()
at mx.controls::Tree/showDropFeedback()
The behaviour is weird, sometimes the browser hangs and stops
responding.
I am calling 'contentTree.showDropFeedback(event)' in my
dragOver
event listener which is triggering error.
My tree data provider is a custom class which has 'children'
array
collection attribute.
Any help on how to resolve this issue would be highly
appreciated.
Thanks in advance,

Drag and Drop between two trees...
Hi ,
Please tell me how to drog and drop from two diffrient trees in a form?
is the any demo for this one .. please let me know if there..
thanks in advance
ManiMani,
this is not possible. Drag and drop works in client-server and even there you can't drag and drop from one tree to another because a tree is an item on its own. You could decide to build your own tree in a Java Bean and then apply drag and drop to it. Its a non trivial task though.

Error in drag and drop with a Tree component
Hello, everybody.
I'm doing a drag and drop with two trees.
But, when I drag from a tree to another show this error:
"oracle.job.RowNotFoundException:JBO25020: View line of oracle.jbo.Key[4.4] key not found in ViewTreeNodeRepository13_71."
Besides that, in my property SelectionListerner, when I have this line: "#{bindings.TreeNodeRepository.treeModel.makeCurrent}" there is a warning that says: "Reference makeCurrent not found".
Anyone can help me?
Thanks!Hi,
+Besides that, in my property SelectionListerner, when I have this line: "#{bindings.TreeNodeRepository.treeModel.makeCurrent}" there is a warning that says: "Reference makeCurrent not found".+
Don't worry, its a designtime warning because the EL cannot be resolved. MakeCurrent is a method on the FacesCtrl binding equivalent to ADF, which is applied at runtime and not available at design time
+But, when I drag from a tree to another show this error: "oracle.job.RowNotFoundException:JBO25020: View line of oracle.jbo.Key[4.4] key not found in ViewTreeNodeRepository13_71."+
In drag and drop, ADF Faces performs the drag. However, the rest of the drop handling is up to the developer. Without any more information of what yur drop handler is doing, this question cannot be answered

Hi All,
I have the latest version configured. In the ALV, I have new feature to drag and drop the column
in the ALV table so that it's position can be changed.
Because of this my columns settings are getting disturbed.
How to disable this feature.
I have already coded as
lr_model->SET_COLUMN_SELECTION_ALLOWED( abap_false ).
lr_model->set_fixed_cols_left_allowed( abap_false ).
lr_model->set_fixed_cols_right_allowed( abap_false ).
Earliest replies are highly appreciated.
Thomas: Any way to do this.
Regards,
Lekha.Hi Lekha,
Please refer to the link below. This link elaborates how to enable Drag and Drop functionality in tables. I hope reversing those settings and properties will disable drag n drop feature.
https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/d0760510-a2d5-2b10-de9f-d897679696e3
I hope this will help your cause.

How to drag and drop a sub tree between 2 treeview?
Suppose I have 2 tree rendered in 2 treeview. Then I want to drag and drop any subtree on any node between the 2 tree.
For example, in tree 1, if I drag node node1 and drop it on tree 2 node node2. I want all nodes from node1(subtree) moved to node 2 in tree 2.
How can I do it? Should I code for treeview 1 begindrag event, and code for treeview 2 dragenter event?
and how to move a sub tree with pb built-in function?Hi Kent,
I have just experimented with drag and drop between treeviews. Below is your bare minimum and caters for one node only. It does not drag any children along. If you drag an item it loses any children. Although it works both ways and within.
The handle is set in the dragbegin events.
In the dragdrop events you get source as an argument which is a pointer to the treeview where the drag started.
You get the node using GetItem ( ref treeviewitem ), then InsertItemSort as a child of the node dropped on.
NOTE: Must uncheck DisableDragAndDrop property for both treeviews.
// Instance Variable
ulong draggedhandle
type tv_1 from treeview within w_treehop
string dragicon = "Form!"
boolean dragauto = true
boolean disabledragdrop = false
end type
event begindrag;
draggedhandle = handle
end event
event dragdrop;
treeview tvSource
treeviewitem ltvidropped, ltvidragged
tvSource = source
if draggedhandle > 0
if handle <> draggedhandle or tvSource <> this then
tvSource.GetItem( draggedhandle , ltvidragged )
this.GetItem( handle , ltvidropped)
this.Insertitemsort( handle, ltvidragged )
tvSource.Deleteitem( draggedhandle )
draggedhandle = 0
end if
end if
end event
type tv_2 from treeview within w_treehop
string dragicon = "Form!"
boolean dragauto = true
boolean disabledragdrop = false
end type
event begindrag;
draggedhandle = handle
end event
event dragdrop;
treeview tvSource
treeviewitem ltvidropped, ltvidragged
tvSource = source
if draggedhandle > 0
if handle <> draggedhandle or tvSource <> this then
tvSource.GetItem( draggedhandle , ltvidragged )
this.GetItem( handle , ltvidropped)
this.Insertitemsort( handle, ltvidragged )
tvSource.Deleteitem( draggedhandle )
draggedhandle = 0
end if
end if
end event
To carry over nested treeview items (children) you can use FindItem ( draggedhandle, navigationcode )
navigationcode as per help:
ChildTreeItem! The first child of itemhandle.
NextTreeItem! The sibling after itemhandle. A sibling is an item at the same level with the same parent.

How to drag and drop nodes in Tree?
Hi,
I want to drag and drop nodes in the tree. For example a tree represents the hierarchy of employees reporting in an organization by using tree.I want to change the reporting an employee visible in the tree by simple drag and drop operation in place of going to another form for updating each employee record indiviually.
Regards
PiyushRon,
I looked into implementing drag / drop in one of the apex trees I created today and ran across this thread. Thank you Ron for the links, it helped a lot.
I added the code below to my page's "Execute when Page Loads" (tree region id is "tree_reg") and the tree is now drag/drop enabled.
It did break the [+] icon from collapsing the tree though ... but the apex.widget.tree buttons still work
var regTree = apex.jQuery("#tree_reg").find("div.tree");
regTree.tree({
callback : {
onmove: function(NODE, TREE_OBJ, REF_NODE, TYPE)
{alert(NODE.id+" "+TREE_OBJ.id+" "+ REF_NODE);}
});Next, I plan on creating a AJAX call using NODE.id, TREE_OBJ.id, and REF_NODE

How do i Drag and drop From one tree to another and vise versa?
I have two tree structures and i'm trying to drag a leaf of a branch from one tree to another and vise versa. i'm using flex 3 to code it. I'm also trying to put a prevention on dropping a leaf of one tree from being dropped inside a branch of another tree. Anything that is dragged over to another tree should be placed as a dangling node in that tree. Please share this code and help me find a solution.

This functionality should work on both the trees. I'll be glad if u can provide the solution.

Oracle Form Developer 6i.Hi jimbo7,
Is this through the Google Calendar web interface, or are you subscribed to the calendar in the Calendar application?
If it is the webpage, I have recently released an application that may help. Multi Event Filter is designed to take dates as text from any source (text of email, CSV or spreadsheet, webpage, text file) and quickly and easily creates events in Calendar. The application is $2.99 to buy on Apple's Mac App Store. You can see more information about it on my website.
On the other hand, if you are subscribing to the calendar in Calendar you should be able to copy the event in Calendar, change the active calendar to the one you want the event in and paste.
Best wishes

I would like to select files from a FileBrowser Tree window (filebrowser.fp) by the Drag -n- Drop method in my GUI. I want to drag a file in the filebrowser, to pull it over a Textbox, and to drop it, so the path and/or the filename appears in the Textbox. I found only one example for 'drag and drop', but it doesnt help, it shows me how to drag-and-drop inside a Tree box, with child items, and so on. (I cannot implement what I saw there due to I am still quite a beginner in LabWin.)
Could somebody give me a short example how to manage this, or a link with an example?
Thank you very much,

Drag and Drop between two ALV Tree.
Hi,
I am trying the drag and drop event between two ALV Tree.
After the occurence of drag and drop event , I am able to get the node key of the source tree node which is dragged . But when the node is dropped onto the target ALV Tree the target node does not gets selected, instead a plus mark appears focussing on the target node in the target ALV Tree. Can anyone suggest a way to get the node key of the focussed target node. Thanks.

Drag and Drop between two ALV Tree Controls
Hello all,
I have designed a spilt control of two ALV Trees using CL_GUI_ALV_TREE.
I have a top node as the Sales order Number and the child node as the items belonging to that sales order number.
Now i need to drag and drop the lines from one sales order to another.
Also these drag drop can take place between the nodes of the two different trees.
Can someone provide with a detail example as i need to complete the same urgently.
