Table

[david_fryda2]

Hi,

I created un table that get results from a BAPI.

Everything works fine.

Now, I am trying to get the line where the user would click on and extract the data of this line.

How do I create a listener and how to get the data, the index of the line selected.... ?

Thanks a lot!

Hi David,

1. Create an action (AN_RowSelect)

2. Assign the action to the "onLeadSelect" property of the table.

3. Create an action handler (onActionRowSelect)

4. In the action handler implement the following code.

int nSelectedRow = wdContext.nodeVnResultTable().getLeadSelection();

IPrivateMyViewView.IVnResultTableElement nodeEltVnResultTable = wdContext.nodeVnResultTable().getVnResultTableElementAt(nSelectedRow);

Once you get the selected row element, you can access the column values by

String col1 = nodeEltVnResultTable.getCol1Value();

String col2 = nodeEltVnResultTable.getCol2Value();

Hope this solves your problem.

Hi David

The following code deals deleting a row similar lines we can select add the row

onActionDeleteProduct()

//@@begin onActionDeleteProduct(ServerEvent)

int n = wdContext.nodeProducts().size();

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

// loop backwards to avoid index troubles

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

{

if (wdContext.nodeProducts().isMultiSelected(i) ||

leadSelected == i)

{

wdContext.nodeProducts().removeElement(wdContext.nodeProducts().

getElementAt(i));

}

}

//@@end

To avoid problems with the index, the context is here executed in reverse. All

elements selected in the table are deleted.

Hope this helped you

Hi,

As Valery said you can retrieve the details of the clicked row using

wdContext.current<node>Element.get<element>

in the actionhandler for the onLeadselect Action of the table.

Thanks everyone, it works!

I just notice that using WebDynPro is not straigh forward as if you were coding the application by yourself.

I do not know how to deliver you the rewards points since you are many people to give me the answers.

So, I will try to do my best.

Thanks again.

Hi,

You can access selected element through getLeadSelection of table data source in onLeadSelect (table event) event handler.

Hi David,

1. Create Action (see coresponding tab of View Controller editor) -- the process is straighforward, no parameters are necessary.

2. Assign action created to Table UI <b>OnLeadSelect</b> property.

3. In generated action handler for this Action you may use wdContext.node<YourTableNode>().current<YourTableNode>Element to get/set properties of record selected.

Hi,

You can get the selected row information from the context as below.

wdContext.current<Node>Element().get<<Attribute1>>

wdContext.current<Node>Element().get<<Attribute2>>

etc

Create an action and bind the action to the OnClick event of the Table and you can write the above statements in the action.
