I’m completely wrong!  Holy crap, I have to go back an fix a lot of apps!

 

Hari, I’ll work on your issue in the other thread.

Huh? I can always be wrong, but I did not think that editable fields automatically updated a dataProvider.  I will go test this now.

Tracy,

            Thank you very much the info. I have a question for you about the NOTE you mentioned in earlier mail. Are you referring editcell event and editField( ) method with reference to new row or in general any cell? To my surprise I did not trap editcell event and did not call editField( ) on cells but I am able to save data changes to the data base, but not the data entered for the new row though. This makes me think that I have to call editField( ) on newly added row, am I correct?

 

Thanks!
Hari

Calling addItem() on the dataGrid is actually calling it on the dataProvider and physically adding the line.

 

Now, that line is empty, the "item" would be undefined (null?), and NOTE THIS: editing a datagrid cell does not automatically update the datagrid.  You will need to use the editCell event to call editField() to update the dp with the entered data.  I bet your dataProvider has a line but it is empty.

Hi,

            I would like to extend the scope of this thread by asking How to make this newly added row as a part of the dataprovider? What I mean is I am able to create a new row in datagrid by using your methodology. But when I try to access data in my POJO, I am getting nullpointer exception. That means, I think, the newly added row to grid is not truly added to dataprovider. Do I have to make any specific function call to make the newly added row attach to dataprovider? If this question is already discussed, please guide me with reference.

 

Thanks!
Hari

Here's a little mod that automatically adds the new row when you tab out of the last cell.  The doLater reminder solved an aggravating problem I was having!

         case "cellFocusOut":

            iItemIndex = oEvent.itemIndex;

            iColumnIndex = oEvent.columnIndex

            if (iColumnIndex == oEvent.target.columnNames.length - 1

                     && iItemIndex == oEvent.target.length - 1 )  {                             //leaving the last row, last column

               oEvent.target.addItem();

               doLater(this,"focusLastRow",[oEvent])

            }

            break;

        

      }//switch (oEvent.type)

   }//checkOnNav

     

   private function focusLastRow(oEvent:Object):Void{

      var dg:mx.controls.DataGrid = oEvent.target;

      dg.setFocus();

      dg.focusedCell = {columnIndex: 0, itemIndex: dg.dataProvider.length-1};

   }//setFocusNextLine

Note:

 

 1.  grid.addItem() will add a blank row

 2.  call focusNewRow() in the next frame using doLater()
