Check box symbol in Tree control

Hi,
I have built a code for using checkbox symbol in tree function and stuck to get the selected check box item.
Actually my requirement is to to use tree with check box and do the multiple selection and get the selected item list. I have completed till the Check box selection but not able to get the all selected item list.
I have attached the code for your reference.
Please let me know hot to do this, If any one knows .
Thanks in advance

Sorry I didn't get here sooner, here is some example code I made a while ago that supports listboxes, MCLB, and Tree selections. It also supports nested levels to the tree, select all or select none, and selecting deselecting parent items, and partial selection of parents if children selection are mixed. Oh and it supports disabling items so the user can't change the selected state.

Check Box in af:tree

Hi,
In my project i need to use Check box in <af:tree> so that i can select some tree nodes .Has anyone tried it before?. any pointers regarding this would be helpful for me.
thanks in advance,

Hi,
Maybe you need to set a partialTriggers in af:selectBooleanCheckbox, referencing to clear button.
Anyway, see this Andrejus' article, perhaps you can on it a better way to achieve that: http://andrejusb.blogspot.com.es/2011/12/adf-tree-how-to-autoselectdeselect.html

Using check Box in a Tree Region style

I want to display some data in a hierarchical manner and use a checkbox for the user to select the node for which he wants to see a report.
I need to fetch the node value where the user has ticked in the check box.
I went through the documentation but it does not mention about using a checkbox.
Can any one please let me know if we can use checkbox to tree nodes and to capture the user checked nodes do we have to make the VO based on an EO or even with a read only VO I can know which node the user has selected.

Check Box in ALV tree

Dear Experts,
Currently a report is being displayed using CL_GUI_ALV_TREE class.
one of the column is check box and it is editable in the output list.
The checkbox column is getting displayed and is editable in all the leafs but I can't see the checkbox in the nodes.
e.g. Node-->Flights chkbx date
            Leaf **       chkbx date
            Leaf **       chkbx date
Can someone tell what could be the problem?

Hi Sravanthi,
I am able to display the check box in the node and it is editable.
Now in the following example, customer wants the check box to be displayed before the key node Flights e.i. in the place of $ there has to be a check box which can be editable.
e.g. Node-->$Flights chkbx date
              Leaf **       chkbx date
              Leaf **       chkbx date
Sravanthi do you have any idea on this. I tried to use change_node and change_item method but could not get the check box in front of the Key 'Flights'

Hi ,
just add the following code in your jsp page---
for (int i = 1; i <= no_of_rows ; i++){
 for (int j = 1; j <= no_of_columns ; j++){
 if(i%2!=0){
mytableView.setStyleForCell(i , j, TableCellStyle.GROUP_LEVEL2);
else{
 mytableView.setStyleForCell(i , j, TableCellStyle.GROUP_LEVEL3);
as it is obvious,this code is to set different colors in alternative rows.
myTableView is the id of TableView.
Refer this link for different colors...

Check Box in Tree (tree multiple selection)

I need to create a 2 level hierarchy tree, where the user is allowed to make multiple selection on leaf node. One way is to use TableTree (TreeByNestingTableColumn), but with this I am unable to get the same look and feel of a simple Tree view.
My questions are:
1. Is there a way to enable multiple selection on a simple Tree?
2. If the answer to question 1 is no, then is there a way to add check boxes to the Tree elements (be it parent or leaf)?
3. Is there anything that can be done to solve this issue without using TableTree?
Thanks in advance.

Hi,
Please go through Multiselection in Tree control thread.
The solution outline is like this:
1. When you click on a leaf, you mark it as selected and you can also store it in the context.
2. Click as many leaves as you like and the onAction will mark each of them as selected.
3. There's no need to do a CTRL+click, only normal clicks.
4. Once done you can find out all the marked leaves.

Satyajit.

How to add check box in SAP B1 grid controls..

hi all,
Anyone know how to add check box in SAP grid control?
It will be great if you could show me some sample code.
thanks.
regards,
sohch

Hi Sohch,
1. First of all you should define the Column in a matrix as it_CHECK_BOX. Like
        oColumns = oMatrix.Columns
        oColumn = oColumns.Add("chk_YesNo", SAPbouiCOM.BoFormItemTypes.it_CHECK_BOX)
        oColumn.TitleObject.Caption = "YesNo"
        oColumn.Width = 60
        oColumn.Editable = True
2. Bind it with a DBDataSource as defined
        oColumn = oColumns.Item("chk_YesNo")
        oColumn.DataBind.Bind("UDTable", "U_YesNo")
3. Make Sure that the value that is being put into the Database is either 'Y' or 'N'.
Hope this Helps

Check box in Tree ui element.

Hi All
I am using org.eclipse.swt.widgets.TreeItem for creating tree structure. Now I am trying to incorporate check box for last tree element. For example if I am preparing tree structure for files the check box should appear only for text file not for directory. User would select the file by checking the box. Here is my code..
for (int i = 0; i < files.length; i++) {
TreeItem item2 = new TreeItem(item1, 0);
item2.setText(files.getName());
item2.setData(files[i]);
if (!files[i].isDirectory())
//here i have to do some thing so that i can select the file in check box
if (files[i].isDirectory()) {
new TreeItem(item2, 0);
I cant use java script here. So pls help me out without using js.
Thanks a lot.

Check box in table control

Hi,
Is it possible to trigger an event by checking the check box in a table control ,
so that i can use it to activate/ inactivate any field in the same table control ?
anoop

with check box alone you cannot trigger an event. You need to use a button also. All you can do is to trigger one event when the check box is checked and another event when the check box is not triggered.

How can I save the all the values of a tree control ?

I have a problem, in run time, I adds new items on a tree control, but i don´t know how I can save the values of the child text of each item in a file.
Thanks.

I'm no expert on the tree control, but I made a small example to save all items to a textfile, including item tag, item string, and indent level. One drawback of this method is that it fully expands the tree regardless how the user left it. To go the other direction, you'd have to write a routine to go through the text file and programmatically build the tree.
To master the tree control, I think you have to resort to creating a control reference for it and using the Invoke Node to do some operations. For another approach to traversing and operating on a tree, check out the "Traversing Tree Controls and Setting Custom Symbols" (search the NI Developer Zone site).
Best of luck,
John

Check box Handling in ALV Tree Control

Hi All,
I am implementing a scenario wherein which I need to get the checked items and process upon the user action. In the implementation I am not getting the checked values.
This is how I have implemented.
I have added a check box field in the Field catalog which is type c
* Item Layout for the Check box.
lwa_item_layout-fieldname = 'CHKBOX'.
lwa_item_layout-class = cl_gui_column_tree=>item_class_checkbox.
lwa_item_layout-editable = 'X'.
APPEND lwa_item_layout TO lt_item_layout.
After that I have tried to used this code to get the checked items.
 CALL METHOD tree1->get_checked_items
 IMPORTING
 et_checked_items = t_checked.
But I am not getting any values in the table.
Further I have tried to use the Event checkbox_change for the check box logic( I am not sure but I thought it is)
But the event is not triggering with this... Please Help me in this regard...

CLASS cl_toolbar_event_receiver DEFINITION.
 PUBLIC SECTION.
* DATA: checked TYPE c,
* fieldname TYPE lvc_fname,
* node_key TYPE lvc_nkey.
 METHODS: on_function_selected
 FOR EVENT function_selected OF cl_gui_toolbar
 IMPORTING fcode.

How to handle check box events in alv tree.

hi,
i am working in CL_GUI_COLUMN_TREE class.Also using Check box. Now i want to handle events for check box . I am new to ABAP Objects.
Pls expaline in detail or send code
thanks in advance,
senthil kumar.r

Hello Senthil
Have a look at the sample report
SAPCOLUMN_TREE_CONTROL_DEMO
. The crucial points are:
(1) Register the required events at the control
* define the events which will be passed to the backend
" checkbox change
event-eventid = CL_GUI_COLUMN_TREE=>EVENTID_checkbox_change.
event-appl_event = 'X'.
append event to events.
CALL METHOD G_TREE->SET_REGISTERED_EVENTS
 EXPORTING
 EVENTS = EVENTS
 EXCEPTIONS
 CNTL_ERROR = 1
 CNTL_SYSTEM_ERROR = 2
 ILLEGAL_EVENT_COMBINATION = 3.
IF SY-SUBRC <> 0.
 MESSAGE A000.
ENDIF.
(2) Set the event handler
assign event handlers in the application class to each desired event
SET HANDLER G_APPLICATION->HANDLE_CHECKBOX_CHANGE FOR g_tree.
(3) Define and implement event handler method
METHOD HANDLE_CHECKBOX_CHANGE.
 " this method handles the checkbox_change event of the tree
 " control instance
 " show the key of the node and the name of the item
 " of the clicked checkbox in a dynpro field
 G_EVENT = 'CHECKBOX_CHANGE'.
 G_NODE_KEY = NODE_KEY.
 G_ITEM_NAME = ITEM_NAME.
 CLEAR G_HEADER_NAME.
ENDMETHOD.
