Issues in Deleting table rows

[Former Member]

Hi all,

After deleting any rows/row in the WebDynpro table it is showing one blank row showing the presence of row there already. This blank row is appearing when we add new row next time. I don't want to appear this blank line after deleting the row. I Used

wdContext.nodename().removeElement();

removeElement() to delete the row.

Is there any other possibilities to avoid this.

Plz let me know.

Hi,

if you want to delete a row in a table use the follwing code,

IWDNodeElement e=wdContext.node<Nodename>().getElementAt(position); //position refers the number of the row which is going to be deleted.

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

HI

How many rows i am deleting that much blank rows are available. Here is the code which i used,

int leadSelected=wdContext.nodename().getLeadSelection();

for(int i=r2-1;i>=0;--i)

{

if(wdContext.nodename().isMultiSelected(i)||leadSelected==i)

{

wdContext.nodename().removeElement(wdContext.nodename().getElementAt(i));

}

}

plz reply.

Hi,

Those blank rows are created by default. if you have 5 rows in your table and table's visible column count is 5, then you delete one row.

Now the table shows 4 rows with values and one empty row, because visible row count is 5. That's why the table automatically add one row in it.

Hi,

Thanks for your reply.

I got your point, but if i set the visible row count as 4, next time if i add one row means that empty row is also displaying. Is there any other way to reduce the visible row count, other than this.

Hi,

Create one value attribute in context and bind it with rowCount property of the table.

After deletion, you have to set the visible rowcount as

int r=wdContext.node<tablenode>.size();

wdContext.currentContextElement().set<visiblerow>(r);

Hi,

Try this code, it may use full for you.

<b>Removing Element</b>

ITestNodeElement ele = (ITestNodeElement) wdContext.nodeTestNode().getElementAt(wdContext.nodeTestNode().getLeadSelection());
wdContext.nodeTestNode().removeElement(ele);

<b>Adding Element to the node</b>

ITestNodeElement testNodeELe = null;
testNodeELe = wdContext.nodeTestNode().createTestNodeElement();
testNodeELe.setTest1("Second ");
testNodeELe.setTest2("Third ");
wdContext.nodeTestNode().addElement(testNodeELe);

It is working fine for me.

Note: - TestNode is the node and Test1 and Test2 are the two elements in the node

krishnaveni,

Now it's hard to understand where is the problem.

Try the following:

1. Make sure that cardinality of node used as Table.dataSource is 0..n (not 1..n)

2. Create calculated read-only attribute of type integer, bind visibleRowCount to this attribute and add the following code as calculated attribute "getter":

return Math.min(wdContext.nodeTableDataSource().size(), 5);
