Hi

to add more than one recoed in the table

wat we do is create an array

decalare this array at the end that is

 /*
   * The following code section can be used for any Java code that is 
   * not to be visible to other controllers/views or that contains constructs
   * currently not supported directly by Web Dynpro (such as inner classes or
   * member variables etc.). </p>
   *
   * Note: The content of this section is in no way managed/controlled
   * by the Web Dynpro Designtime or the Web Dynpro Runtime. 
   */
  //@@begin others

//this is the array used in the program
  String emp[][]=
	{
	
	  {"nikhil","tapkir","pune"},	
	
	
	 { "juhi","bhatnagar","delhi"}, 
	
	};
  //@@end
}

i have to insert the above information in a table wid columns firstname lastname and city .

u need to use the for loop to insert the data in the table for more than 1 record

code the following thing in wd init

here fname lname and city are my value attributes mapped to my table columns.

for (int i=0;i<emp.length;i++)
	  {
   
	  IPrivateTabappView.ITablenodeElement tnode=wdContext.createTablenodeElement();
	  
	  tnode.setFname(this.emp<i>[0]);
	  tnode.setLname(this.emp<i>[1]);
	  tnode.setCity(this.emp<i>[2]);
	 wdContext.nodeTablenode().addElement(tnode);
	  }

i hope this is what ur doubt was if not pls clarify.

hope this helps u.

Hi Hema,

To populate a table with multiple rows please use the following piece of code:

For example: Consider that the value node DataNode having two attributes A and B is bound to the DataSource property of your Table UI Element.

IDataNodeElement objDataNode = null;

ArrayList arlDataNode = null;

int size = 0;

size = <No. of rows that you want in the table>;

arlDataNode = new ArrayList();

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

{

objDataNode = wdContext.createDataNodeElement();

objDataNode.setA(<Set some values>);

objDataNode.setB(<Set some values>);

arlDataNode.add(objDataNode);

}

wdContext.nodeDataNode.bind(arlDataNode);

Hope this of help to you.

hi

You have to create nodeelement for each row,to fill the values in each row of a table.

and bind this element to the node.

Try this simple code.

node-->Person

attributes-->Fname

Lname

Number

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

{

IPrivateFirstCompView.IPersonElement pelem=wdContext.nodePerson().createPersonElement();

pelem.setFname("fname"+i);

pelem.setLname("lname"+i);

pelem.setNumber(i);

wdContext.nodePerson().addElement(pelem);

}

or you can get the values from inputfields in a view and set to the table.

hi,

IPrivate<ur view name>View.I<Node Name>Node i<Node Name>Node = wdContext.node<Node Name>();

IPrivate<ur view name>View.I<Node Name>GridElement i<Node Name>Element ;

for(int i=0;i<10;i++){

i<Node Name>Node.create<Node Name>Element();

i<Node Name>Element .set<Your Attribute>("value"+i);

i<Node Name>Node.addElement(i<Node Name>Element );

i<Node Name>Node.moveNext();

}

thanks,
