what is the code for finding a node that how many attributes it is holding in runtime

Thanks in advance.

Dear Krishnakk

You can call the SIZE() method of the NODES and LENGTH() method on ATTRIBUTES.

Like if you have node Employee and Employee_ID and Employee_Name are attibute under it. suppose you have already populated the node employee.

***what is the code for finding a node that how many attributes it is holding in runtime

You have to identified the which node will be called based on the user actions;

You can fin the size of the node to identify number of the rows holding at runtime. loop through for to find the attributes

IWDMessageManager messageManager = wdComponentAPI.getMessageManager();
if(wdContext.nodeEmployee.size() > 0)
{        
         //Print Node size           
         messageManager.reportSuccess("Size of the Node ::"+wdContext.nodeEmployee.size() );
         for(int i=0; i<wdContext.nodeEmployee.size(); i++
          {
                 //Print Length of the Attributes Employee ID and Name
                 messageManager.reportSuccess("Length of the Employee Name ::"+wdContext.nodeEmployee().getEmployeeElementAt(i).getEmployee_ID().length());
               
                 messageManager.reportSuccess("Length of the Employee ID ::"+wdContext.nodeEmployee().getEmployeeElementAt(i).getEmployee_Name().length());
      
          }
}

Hope it will helps

The size of a context node is the number of elements stored in the node. I never heard the notion "length" of a context node. What do you mean with "how many attributes it is holding in runtime"?

Go through this help of node properties.

code for finding a node that how many attributes it is holding in runtime

int size = wdContext.nodeName().size();
for(int i=0;i<size;i++)
{
     //Display the node elements
     wdComponentAPI.getMessageManager.reportSuccess(wdContext.nodeName().getNodeElementAt(i).getAttName());
}
