Oracle forms Hierarchical tree

user6672850Jun 23 2016 — edited Jun 25 2016

Hi All,

I am working on Oracle form version : 10.1.2.0.2 and database : 11g Enterprise Edition Release 11.2.0.4.0

I have a requirement and we need to develop dynamic form to full fill our requirement.

so if we are saying dynamic means user can add and delete text item at run item.

Few points related to requirements are given below :

1.The number of node we need to populate around 100+ ( at all level)

2. We have relation like :

a. parent: Main parent

b. ---Parent1 : Child of parent and parent for others

c. -------Parent2 : Child of parent1 and parent for others

d. ---------Child : Child of parent2

3. Every level we have some text item which we need to display on basis of some selection at parent level

4. User can delete the item from any level.(If I am saying deletion means just delete from this record not from the database).

and on the basis of my selection at parent level we need to populate our child.

5. I have started my analysis with keep in mind that we can achieve this requirement by Oracle Hierarchical tree in Oracle forms but looking your suggestions as well if you have any..

Please let me know if the requirement is not clear and you want some more details on this..

Thanks in advance...

>so if we are saying dynamic means user can add and delete text item at run item.

You cannot create textitems dynamically.

What is the requirement behind this? Is each textfield a custom property?If so, the common approach is to have a number of hidden textitems in your datablock (lets say 20) and at runtime dynamically show or hide them depending of the data conditions you have.

For the second requirement with the tree... Unfortunately you cannot display textitems in a forms-tree. I'm not sure if i understand your requirement correctly, but maybe you are talking about a treetable as described here. Building a treetable-like form (part 2) - Andreas Weiden - About Oracle

If you need further assistance, please give more details on your requirements.

Hi Andreas .. Thanks for quick reply...

We have around 200 items and user can select any number of items out of 200. eg. 50 or 80 or 150 or 200..so its really hard to manage show and hide at run time..

and the structure of my form will be like that....

Parent

Child1

Child11

Value

possible value YES or no if yes then we need to display all item like child11… child14 . If value is NO then we need to display only child11 and child 14. we need to hide child12 and child13

Child12

Value

Child13

Value

Child14

Value

Child2

Child21

Value

Child22

Value

Child23

Value

Child24

Value

Child3

Option1(chkbox-Selected)

Option2 (Selected)

Option3(chkbox)

Child31

value

Possible value yes or no. If value is yes then we need to display all item from child 31.. Child33. if value is no then we need to hide child32.

You can see the Option 1 ,Option2 and Option3.if user select all the checkbox then in child31 option we want all three input values from user. like user selected option1 and option 2 so we need to display Option_1_item and Option_2_item in canvas.

Option_1_item

Value

Option_2_item

value

Child32

Child33

I do not understand the dependencies between different childs in the tree. Can you explain the rules a little more detailed?

Are the options always at the last level of the tree?

Does the tree have a fixed depth?
