I try to set like this:

> 
> `ListBox lb = new ListBox();  
> 
>  /* Bind datas */  
> 
>  lb.SelectedItem = someObject;`
> 
> 
> 

lb truely selected the someObject item. But it would select the 1st item at first. And that motion cause SelectedIndexChanged event which I don't wanted.

I just want SelectedIndexChanged be called when someObject selected.
How could I do to fix this?
