RE: [flexcoders] creating row in datagrid at runtime

Fri, 20 May 2005 13:32:16 -0700

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!

 

<?xml version="1.0"?>

<mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml"

      xmlns="*">

<mx:Script><![CDATA[

     

   function checkOnNav(oEvent:Object):Void

   {

      var iItemIndex:Number;

      var iColumnIndex:Number;

      switch (oEvent.type)

      {

         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

  

]]></mx:Script>

   <mx:DataGrid id="grid" editable="true"

         cellFocusOut="checkOnNav(event)">

      <mx:dataProvider>

         <mx:Array>

            <mx:Object name="manish" colour="red" />

            <mx:Object name="abdul" colour="blue" />

         </mx:Array>

      </mx:dataProvider>

   </mx:DataGrid>

 

</mx:Application>

<?xml version="1.0"?>

<mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml"

  xmlns="*">

  <mx:Script>

    function enterNewRow():Void

    {

      grid.addItem();

      focusNewRow();

      doLater(this, "focusNewRow");

    }

    function focusNewRow():Void

    {

      grid.setFocus();

      grid.focusedCell = {columnIndex: 0, itemIndex:

grid.dataProvider.length-1};

    }

  </mx:Script>

  <mx:DataGrid id="grid" editable="true">

    <mx:dataProvider>

      <mx:Array>

        <mx:Object name="manish" colour="red" />

        <mx:Object name="abdul" colour="blue" />

      </mx:Array>

    </mx:dataProvider>

  </mx:DataGrid>

  <mx:Button label="Enter New Row" click="enterNewRow()" />

</mx:Application>

 

Note:

 

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

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