How to populate the master column in a table

[arjun_thakur]

Hi Experts,

I am trying to implement a hierarchy structure in a table. For that I have inserted a master column of TreeByNestingTableColumn type. The value which are getting displayed in a table are hard coded by me, but I am not able to understand how should I populate the values so that when the table initially appears, it should contain some data (which I hard code) and when I click the master column, it should expand and display value according the master column selected(which I again hard code).

Please help me in achieving it.

Regards

Hi,

Go throgh the tutorial "Creating a Tree Structure in a Table" in the blow link.

In these example only the souce of data changes as per your requriement. In the examples they are reading data from java class.

1. First you need to create a value node with (Parent Id, Boolean Type: isLeaf, Expanded, ChildernLoaded), attributes.

2. Then you have to create one recursive node under that Value node by selecting that node as reference.

3. As given in the example create one method called addChildern(Node, ParentId).

4. Now in the wdDoInit method call this method by passing the Value node and "ROOT" as parent Ids

5. In addChildern method if parentId is ''ROOT" then populate all the root elements in the parent node.

6. Now root elements will be populated.

7. When user clicks on any of the root element then invoke the action loadChildern(this should be binded to Master column) and pass recursive node of that parent element and the parenId (as given in the exmaple).

8. Based on this parentId now populate the chids in addChildern method.
