Dear Experts,

In my webdynpro application I am recieving a table from my Model, I have to read table rows fields and set them into my value attributes.

Request you to please suggest, and provide some code examples.

Hi Upendra,

Please go through this link:

Please note that there is method provided by the WDCopyService however i guessin this case that will not work since you want to transfer the model node data to value node. So you would have to iterate over the model node and set the values of the attributes in the value node.

Its similar requirement.

Thanks nad Regards,

My requirement is not to read the full table I have to just read a single line from the table and assign the values of that rows to my value attributes not value node, I know the index from which I have to read.

Please suggest.

Hi,

If you now the index use the following code

//Node used is "Employee"
// replace x with index
IEmployeesElement empElement = wdContext.nodeEmployees().getEmployeesElementAt(x);

hi

catch the size of the table .

set the for loop

int i=wdcontext.TableName.size();

leadSelection = wdcontext.node<NOdename>.getLeadSelection();

for(int i=0;i<ni++)

{

if(wdcontext.<nodeNOdeName>.isSelected(i) || leadSelection==i)

{

fetch the data from the table using the index .

String abc = wdcontext.node<Table Name>.getElementNameatindex{}.get<element>;

you can then store this values in the value attribute you need.

}

the above code will help you single row selection . and if the user wants multi selection simply change the if condition as if(wdcontext.<nodeNOdeName>.ismutliSelected(i) )

or

if you want both then use write both if conditions .

Hi,

Like Ayyapparaj KV suggested, I'd use the same piece of code;

IEmployeesElement employeesElement = wdContext.nodeEmployees().getEmployeesElementAt(x);
IEmployeesFormElement employeesFormElement wdContext.nodeEmployeesForm().currentSelection();
WDCopyService.copyElements(employeesElement, employeesFormElement );

I'm guessing here that you want to do some sort of Editable Form, which is kinda common. I'd use 1.1 in the Form node. Just remember, you need the same Value Attribute Name / Type in order to use the Copy.

Hi ..

you have to use code like

target cardinality should be---0:N...

WDCopyService.copyElements(source,target)

Hi,

int size = wdContext.node<name>().size();

int leadSelection = wdContext.node<name>.getLeadSelection;

for(int i=0; i<size; i++)

{

if (wdContext.node<name>().isMultiSelected(i) || leadSelected == i)

{

I<node name>Element ele = wdContext.node<name>().get<Attribute>ElementAt(i);

// now get the attributes of the element ele and set it to the desired node element.

}

}

hope it helps you meet your requirement,

Jithin.
