Get the value from a selected row in a table

[Former Member]

Hi all,

My table contains a tree structure.

When I select a single row, I need to get the value of a particular column.

I created an action on the leadSelect of the table and gave the following code:

public void onActionleadValue(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )

{

//@@begin onActionleadValue(ServerEvent)

String strLeadValue = wdContext.nodeAttribute_View_Out().currentAttribute_View_OutElement().getAttributeAsText("<MyModelAttributename>");

wdComponentAPI.getMessageManager().reportSuccess("selected lead value "+strLeadValue);

wdContext.currentContextElement().setLeadselectedvalue(strLeadValue);

//@@end

}

My Bapi returns me 6 records. and when I click on any row its always pointing to the last record value.

What could be the problem?

Thanks

Anjana

It is simple.

Let us assume, Table is your node and name is your value attribute.

Table

- name

wdContext.nodeTable().getLeadSelection(). - is the lead selection.

wdContext.nodeTable().getTableElementAt(wdContext.nodeTable().getLeadSelection()).getName());

Hi Sridhar,

Thanks for your reply.

I am able to get the lead selection values.

But now the problem is I am displaying the values from my bapi in a hierarchy inside my table.

My hierarchy looks like this:

S(Parent) //row 1

---SChild1 //row 2

-

---

SChild1Leafattribute1 .......attribute2.....attribute3 //row 3

-

---

SChild2 //row4

-

---

SChild2Leafattribute1 .......attribute2.....attribute3 //row 5

I am able to get the value of my S(Parent).But not able ti get the value of my SChild1,SChild1Leafattribute1,attribute2 and attribute3.

How can I get these values on my lead select(for eg. on clicking row3)?

Thanks

Anjana.

Hi,

Use treeselection

Ex: wdContext.node<Your Context>().getTreeSelection();

If you want the selected one in any of the actions of the table then you can map the nodeElement

IWDTable tab =//Your table;

Ex:tab.mappingOfOnLeadSelect().addSourceMapping(IWDTreeNodeType.IWDOnLoadChildren.NODE_ELEMENT, "element");

Hi Anjana,

Try this.

try

{

IWDMessageManager msg = wdComponentAPI.getMessageManager();

int leadselect = wdContext.nodeSChild1().getLeadSelection();

for(int i=0;i<wdContext.nodeSChild1().size();i++)

{

if(leadselect == i)

{

//Displaying output in diff table

// IPublicTestComp.ITableNodeElement tabelm = wdContext.createTableNodeElement();

// tabelm.setAttribute1(wdContext.nodeSChild1().getSChild1ElementAt(i).getAttribute1());

// tabelm.setAttribute2(wdContext.nodeSChild1().getSChild1ElementAt(i).getAttribute2());

// tabelm.setAttribute3(wdContext.nodeSChild1().getSChild1ElementAt(i).getAttribute3());

// wdContext.nodeTableNode().addElement(tabelm);

String att1 = wdContext.nodeSChild1().getSChild1ElementAt(i).getAttribute1();

String att2 = wdContext.nodeSChild1().getSChild1ElementAt(i).getAttribute2();

String att3 = wdContext.nodeSChild1().getSChild1ElementAt(i).getAttribute3();

msg.reportSuccess("Row ("i") : "att1"====="att2"======"+att3);

}

}

} catch (WDDynamicRFCExecuteException e) {

wdComponentAPI.getMessageManager().reportException("Message : "+ e.getMessage(),true);

}

Hi Mithu,

Thanks for ur response.

But SChild1 is my data in the row, its not a value node or model node.

I tried with my value node, but still it was not retrieving the attribute values.

Hi Ayyapparaj,

I am giving the following code in my wdDoModify method.

IWDTable myTable = (IWDTable)view.getElement("tblfortree");

myTable.mappingOfOnLeadSelect().addSourceMapping(IWDTreeByNestingTableColumn.IWDOnLoadChildren.AttributeViewElemet,"element");

Its giving me error under (IWDTreeByNestingTableColumn.IWDOnLoadChildren.AttributeViewElemet,"element");

I dont have IWDTreeNodeType option. I am using tree by nesting table column for creating my tree structure.

Please guide me how to goahead.

Thanks

Anjana.

Hi

I gave the following code

IWDTable myTable = (IWDTable)view.getElement("tblfortree");

myTable.mappingOfOnLeadSelect().addSourceMapping("row","element");

public void onActionleadValue(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent, int element )

{

//@@begin onActionleadValue(ServerEvent)

wdComponentAPI.getMessageManager().reportSuccess("element is "+element);

}

And I am able to get the integer value for each selected row. For eg. if I select the first row, element = 0, if I select row2 element =1 and so on in my tree hierarchy.

Now I want to get the attribute value (column value)in a selected row.

I tried

String strCCode = wdContext.nodeAttributeView().nodeAttributeViewNode(Lead).nodeAttributeViewNode(element-2).getAttributeViewElementAt(element-2).getAttributeAsText("Zcstcd");

Its giving the costomer code value in the third row. But if I click on row 4 its not giving me any value for csutomer code.

How can I get the values?

Thanks

Anjana.

Hi,

Change the following

myTable.mappingOfOnLeadSelect().addSourceMapping(IWDTreeByNestingTableColumn.IWDOnLoadChildren.AttributeViewElemet,"element");

To

<b>myTable.mappingOfOnLeadSelect().addSourceMappingtab.mappingOfOnLeadSelect().addSourceMapping("nodeElement", "element")</b>

<b>element</b> is of type <b>IWDNodeElement</b>

Hi Ayyapparaj,

If I use your code, its returning me the node((TitleMaintenanceView.AttributeView.0.AttributeViewNode.0.AttributeViewNode.0)

at the selected row.

But my aim is to get the attributes in that row.

Since the tree is getting created dynamically, how can I get the values inside it?

Thanks

Hi,

If your attribute is of Type IWDNodeElement

then you can access the attributes using

IWDNodeElement nodeElement;

nodeElement.getAttributeValue(attributeName)

Hi Ayyapparaj,

I am able to solve the problem by creating the NodeElement as u suggested. Here is how I proceeded.

IAttributeViewElement myElement =(IAttributeViewElement)wdContext.nodeAttributeView().getTreeSelection();

myElement.getEwbez();

wdComponentAPI.getMessageManager().reportSuccess("Tree Selection "+ myElement.getEwbez());

Thanks for you suggestions.

Have awarded points!

Anjana.

Hi Anjana,

If your table contains a tree structure.

then for getting the correct child selection, you should use :

IWDNodeElement elemnt= wdContext.nodeTable().getTreeSelection();
