Change the editing status of the current row after selecting the table row in the ADF.

Change the editing status of the current row after selecting the table row in the ADF.

 

Now, select a row in the table. The upload button for this row is available, and the unselected row is unavailable:

 

 

The specific implementation method is as follows:

1. corresponding table code. Use the <selectionListener> attribute Association implementation class.

<Af: table value = "# {bindings. PtsTestVVO1.collectionModel }"
Var = "row" width = "100%"
Rows = "# {bindings. PtsTestVVO1.rangeSize }"
First = "# {bindings. PtsTestVVO1.rangeStart }"
EmptyText = "# {bindings. PtsTestVVO1.viewable? 'No rows yet. ': 'Access Denied .'}"

SelectionListener = "# {testBean. selectionChanged }"
Banding = "none"
Binding = "# {testBean. testTable}">

 

2. The code corresponding to the "Upload" button. Pay attention to the disabled method.

<Af: commandButton text = "# {res ['upload']}"
UseWindow = "true"
Required wheight = "600" required wwidth = "450"
Immediate = "true" disabled = "# {row. Flag = '0 '? True: false }"
Action = "# {testBean. uploadFile}">

 

3. In the corresponding implementation class, the flag value is changed each time the current row is selected.

Public void selectionChanged (SelectionEvent selectionEvent ){
UIComponent cmp = selectionEvent. getComponent ();
// Obtain the current TABLEID
DCBindingContainer tableBindings =
(DCBindingContainer) getDCBindingContainer ();
DCIteratorBinding iterBinding = tableBindings. findIteratorBinding ("PtsTestVVO1 ");


String strID = cmp. getId ();

CoreTable tableReceiptOrderAssign = this. getTableOjb (strID );
// Traverse VO set Falg \
ViewObject VO = this. getPtsAM (). findViewObject ("PtsTestVVO1 ");
Int rowCount;
Int rowCount0 = VO. getRowCount ();
Int rowCount1 = VO. getRangeSize ();
If (rowCount0> = rowCount1 ){
RowCount = rowCount1;
} Else {
RowCount = rowCount0;
}
For (int I = 0; I <rowCount; I ++ ){
VO. getRowAtRangeIndex (I). setAttribute ("Flag", "0 ");
}
Set rowSet = tableReceiptOrderAssign. getSelectionState (). getKeySet ();
If (rowSet. size () = 0 ){
Return;
}
Iterator rowSetIter = rowSet. iterator ();
While (rowSetIter. hasNext ()){
Key key = (Key) rowSetIter. next ();
IterBinding. setCurrentRowWithKey (key. toStringFormat (true ));

RowImpl curentRow = (RowImpl) iterBinding. getCurrentRow (); // get the current row
CurentRow. setAttribute ("Flag", "1"); // you can specify a Flag.
}
AdfFacesContext. getCurrentInstance (). addPartialTarget (tableReceiptOrderAssign );
}
