How to remove multiple rows from table

[Former Member]

Hi All,

in my application iam using two tables,

this is my code

int selection = wdContext.nodeA().getLeadSelection();

String num = wdContext.nodeA.geAAt(selection).getV_Num();

for(int b=0;b<wdContext.nodeVn_Context().size();b++)

{

if(wdContext.nodeVn_Context().getVn_ContextElementAt(b).getVa_num().equalsIgnoreCase

(num))

{

wdContext.nodeVn_Context().removeElement(wdContext.nodeVn_Context().getVn_ContextElementAt(b));

}

}

here Vn_Context is having 4 rows, i mean size of Vn_Context is 4. when i use this code to remove that 4 rows based on the condition, which i gave in if, its able to remove only one row, so how to remove those four rows, is this code correct or not, please help me.

Hello Sushma,

Assuming that your node allows multi-selection, use the following method:

Loop over the elements and select each element using the setSelected() method, according to your condition, eg.

wdContext.nodeXXX.setSelected(idx, true/false)

At the end of the loop call the method removeSelectedElements().

wdContext.nodeXXX.removeSelectedElements();

Hi,

Try this code,

for (int i = wdContext.node<Node>().size() - 1; i >=0; --i)

{

I<Node>Element e = wdContext.node<Node>().get<Node>ElementAt(i);

if ( condition_to_delete(e) )

wdContext.node<Node>().removeElement(e);

}

Hi,

Write this code in your method.

int n = wdContext.nodeA().size();
int leadSelected = wdContext.nodeA().getLeadSelection();
String num = wdContext.nodeA.geAAt(selection).getV_Num();



	
		// loop backwards to avoid index troubles
		for (int i = n - 1; i >= 0; --i) 
{
if(wdContext.nodeVn_Context().getVn_ContextElementAt(b).getVa_num().equalsIgnoreCase
(num))
{

		  if (wdContext.nodeA.isMultiSelected(i) || leadSelected == i) 
{
			wdContext.nodeA().removeElement(
			  wdContext.nodeA().getElementAt(i));
		  }
		}
}

Thanks

hi

instead of the forward loop , try reverse loop.
