[flexcoders] Re: Datagrid scrolling woes!

2006-12-29 Thread farmetha 
I'm having a very similar problem with a list control.  I have a data
model that has a cursor position that my list binds to, i.e.

mx:List width=200 height=100 dataProvider={dataModel}
   selectedIndex={dataModel.cursorPos}/

When I refresh my data model it automatically scrolls me back to the
top  of the list, it keeps my selectedIndex correct but if it is a
higher number than the viewed items it will be off of the viewed area.
 I tried adding in verticalScrollPosition={dataModel.cursorPos} but
it acts even stranger.  It still scrolls me to the top of my list and
adds a few empty lines at the top.

I am wondering if the scrollToIndex method will help with this and was
wondering if anyone else had come up with an easy solution to this.

I don't know if you're just trying to be misleading, or mis-typed 
something, but it doesn't help any if you're passing wrong 
information.

DataGrid (or List for that matter) doesn't have a vPosition property 
at all. 

I don't know the answer for sure, but there's a 'scrollPosition' 
property on dataGrid.verticalScrollBar ... thats the one I'd look at 
first.

good luck.

 Hello all, I'm trying to accomplish something that is seemingly
 easybut is driving me bananas due to the fact that it's not 
working.
 I want to setup a function that can be called and that function 
will
 scroll my datagrid to a specific row within that datagrid.
 
  
 
 Here's what I've got (that doesn't work)any thoughts?

Oops, maybe that was 1.5.  I'll check a bit.  And all my advice comes
with a money-back warranty!
