the way you focus on a cell, is you have to set the datagrid
focusedCell property.
you could do the following.
1) always save the currentcell position in cellFocusIn
2) make the remoteobject call whenever the datagrid change is
trigerred and set a boolean variable. (Now are you sure you want to
make that remoteobject call after a DataGrid.change event. I dont
think 'change' is trigerred if you use the tab key.)
3) then in back in your cellFocusIn function, check the value of
this boolean. if its false, refocus back on your recently focused
cell
eg (untested)
<mx:Application>
<mx:DataGrid id="dg" cellFocusIn="doCellFocusIn" change="doChange">
<mx:Script>
var validationResult:Boolean;
var myCell;
function doChange()
{
//make your remoteobject call - return handler(returnDoChange())
}
function returnDoChange()
{
validationResult = true or false
}
function doCellFocusIn(event)
{
if(validationResult || myCell == undefined)
{
myCell = {itemIndex:event.itemIndex,
columnIndex:event.columnIndex};
}
else
{
this.focusedCell = undefined;
this.focusedCell = myCell;
}
see if something like this is any good for you.
